Introduction  
The Worth Data RF Laser has the following features:  
1) The LZ400-RF Laser Scanner for the USA and Canada. This laser has  
a range of up to 500 feet (open area) and has collision detect and retry  
logic built within. The LZ400-RF Laser communicates with the B78  
Base Station. The Base Station communicates with a host PC through the  
USB port or a RS-232 Serial Port. Up to ten LZ-400 RF Lasers can  
communicate with one B78 Base Station.  
2) If you use the USB interface, data is transmitted as keyboard data. If you  
use the serial interface instead, serial data is transmitted to one of the  
computer's COM ports.  
3) The USA LZ400-RF Laser and Base operate in the 902MHz band. The  
laser and base radios operate by "frequency hopping" spread spectrum.  
The radios hop from one frequency to another every 400ms. The radio  
goes through 25 different frequencies and then repeats the sequence – all  
in the 902 MHz band at 15 milliwatts (10 dBm) of power. Different  
sequences define the channels. It is possible to have up to ten RF  
Lasers/Base Stations in the same area, providing each pair is on separate  
channels to avoid interference and general confusion. The RF Laser can  
also operate in the same room as the 701 RF Terminal.  
4) The R/F Laser can read and discriminate between Code 39, Full ASCII  
Code 39, Interleaved 2 of 5, Codabar, Code 128, EAN-13, EAN-8, UPC-  
E, UPC-E1, UPC-A, MSI, LabelCode4, LabelCode5, Code 93 and  
Plessey.  
5) The RF Laser has a rechargeable lithium ion battery. The battery is  
recharged with the included F10 5v power supply. Recharge time on  
fully discharged batteries is 3 hours. Do NOT use any other power  
supply to charge your laser.

Installation  
Components of RF Laser Readers  
In the event the shipping box shows damage on arrival, please note the  
damage on the carrier's receipt log.  
The supposed contents of your Reader shipment is the following:  
1. An B78 RF Base Station with 1-10 LZ400-RF Lasers.  
2. A Worth Data regulated 5V power supply with each LZ400-RF Laser  
Scanner ordered, and if you ordered a serial cable with the B78 Base  
Station, you will receive a power supply for the Base also. TO  
PREVENT DAMAGING the Base Station or RF Laser, DON'T USE  
ANY OTHER BRAND OF POWER SUPPLIES.  
3. Either a serial cable (F36) or USB cable (C21), depending on which one  
you ordered.  
4. A plastic barpad for entering variable quantity information and  
performing the Link Test without data transmission.  
Scanner Beeps and LEDs (what they mean)  
When you scan, you will get one beep when you get a successful decode and a  
high-pitched beep. The data is then transmitted to the Base Station (as it is  
being transmitted, the LED flashes yellow). When the Laser receives the  
acknowledgement from the Base Station that the data has been received, the  
Laser emits a lower pitched beep and turns on a green LED for three seconds.  
If the transmitted data fails to be acknowledged,  
1) further scanning is prohibited. You can't pull the trigger again  
until the data reaches the base or until you clear the scanner.  
2) The laser will retransmit three times, (the yellow LED will  
indicate retransmissions).  
3) If it fails three times, it will emit a distinct 8 beep pattern and  
turn off. This is your clue to check out the Base Station.  
4) You can pull the trigger to try transmission again. (the laser beam  
will not come on until the transmission is acknowledged or you  
hold the trigger down for 30 seconds to clear the data).

USB Installation  
USB attachment does not require the Worth Data F10 5v power supply for the  
B78 Base Station. If for some reason your USB port or hub does not have  
enough power to operate the Base Station correctly, you may use our F10  
power supply, but you must plug it in AFTER you have powered up on the  
USB cable only. The Base Station will power up with 3 more flashes than the  
channel setting; i.e. if it is set on Channel 0, it will flash green three times. If  
the Channel were set to 7, it would flash green 10 times.  
Once you connect the B78 Base Station to the computer using the supplied  
USB cable, the Base Station should be sensed automatically by the computer  
and the driver installation will begin. Windows can usually find the necessary  
driver on the hard drive under /Windows/System 32/Drivers; occasionally you  
will have to insert the original Windows CD. The Mac always finds the driver.  
In either case, the driver used is the standard keyboard driver. No special  
drivers are required.  
You should be connected as below:  
If you mistakenly abort your driver installation, see the Trouble Shooting  
Section of this manual.  
For testing, bring up Notepad or WordPad on your computer and scan the  
TEST LABEL on page 21. Now turn to page 7.

Installing the R/F Reader with a dedicated serial port  
The Base Station can be directly attached to a spare serial port as shown  
below. This configuration requires the Worth Data F10 5v power supply for  
powering the Base Station. Upon power-up, the Base Station LED will flash  
with 3 more flashes than the channel setting; i.e. if it is set on Channel 0, it  
will flash green three times. If the Channel were set to 7, it would flash green  
10 times.  
Your software will need to read the serial port as a separate device, unless  
you're using an IBM-compatible computer and Worth Data’s PortKey  
software, which makes serial-port data appear as though it had been typed at  
the keyboard. You can also use the WDR Test Utility to test communication  
with your com port.  
If you specified a 25-pin null-modem cable (part number F34) or a 9-pin cable  
(part number F36) when you placed your order, you can cable directly from  
the RF/Reader's Y-Cable port to your computer's serial port. Refer to page 6  
for the details of the pin-outs of the cables.  
Turn to page 7 to configure the RF Laser Reader using the Setup Menu.

Installing the R/F Reader between a computer and  
terminal  
If you attach the s Base between your computer and a terminal, as shown  
below, using Cable Selection F45-1, bar code data will be sent to the computer  
as if it had been typed on that terminal. Refer to page 8 for the details of the  
pin-outs for each connector on the cable. You will also need to change jumpers  
(JP2 on the RF Base) on the board inside the case from the “S” position to the  
“Y” position.  
This configuration requires the Worth Data F10 5v power supply for powering  
the Base Station. Upon power-up, the Base Station LED will flash with 3 more  
flashes than the channel setting; i.e. if it is set on Channel 0, it will flash green  
three times. If the Channel were set to 7, it would flash green 10 times.  
Cables may require modification, depending on the genders and pin-outs of  
your serial ports and cables. You may require "gender changers" (available at  
most computer stores) for the two 25-pin connectors. Refer to page 6 for the  
details of the pin-outs of the dual port serial cable.  
Turn to page 7 to configure the reader using the RF Laser Reader Setup  
Menu.

Configuring the RF Laser Reader  
for your computer and application  
The RF Laser Setup Menu is located in Appendix J of  
this manual. This simple menu lets you easily configure  
the RF Laser to work with almost any computer system,  
and to tailor its bar code reading and data format  
characteristics.  
Be sure to read the scanning instructions on the next  
page. To read Reader Setup Menu bar codes and  
configure your reader, you must know the right way to  
scan bar codes.  
These are the RF Laser Reader's default settings and are shipped configured to  
these settings; they can be reset to them at any time by scanning the Start  
Setup and Reset codes on the RF Laser Setup Menu.

Laser Scanning Instructions  
Using a laser scanner is basically as simple and intuitive as "point and shoot"  
at a distance of 0-24", depending on the density of the bar code.  
Basically, the laser scanner's beam must cross every bar and space on the bar  
code, without touching any other bar codes, as shown in the first example  
below. You'll need to hold the scanner further away to produce a wider beam  
for large bar codes, and closer for bar codes with bars very close together.  
Even though momentary exposure to a laser's low-power, visible-light is not  
known to be harmful, you should not aim the beam into anyone's eyes.  
When you scan, you will get one beep when you get a successful decode and a  
high-pitched beep. The data is then transmitted to the Base Station (as it is  
being transmitted, the LED flashes yellow). When the Laser receives the  
acknowledgement from the Base Station that the data has been received, the  
Laser emits a lower pitched beep and turns on a green LED for three seconds.  
If the transmitted data fails to be acknowledged,  
1) further scanning is prohibited. You can't pull the trigger again  
until the data reaches the base or until you clear the scanner.  
2) The laser will retransmit three times, (the yellow LED will  
indicate retransmissions).  
3) If it fails three times, it will emit a distinct 8-beep pattern and  
turn off. This is your clue to check out the Base Station.  
4) You can pull the trigger to try transmission again. (the laser beam  
will not come on until the transmission is acknowledged or you  
hold the trigger down for 30 seconds to clear the data).  
The important thing to remember about using a laser with the RF Laser Reader  
Setup Menu is that you need to make sure the scanner's beam covers only one  
bar code at a time. The laser scanner's beam is wide enough, and the  
configuration bar codes close together enough, that you will need to use your  
fingers, post-it notes, or the supplied Laser Setup Assist window, to "block  
off" bar codes adjacent to whatever configuration bar code you need to read.  
8
 
For example, to  
read this "5" bar  
code on the Setup  
Menu, you would  
need to cover any  
adjacent bar codes  
with paper or a  
finger first, as  
shown.  
Don't forget to take the R/F Laser Scanner of Setup Mode by scanning End  
Setup, otherwise the batteries will run down totally because the radio  
transmitter remains on.  
Using The RF Laser Setup Menu  
1. To configure your reader using the Reader Setup Menu found in Appendix J  
of this manual. You must first scan the Start Setup code at the top left corner.  
Do this now. You'll hear two beeps. During Setup, nothing will be  
transmitted to your computer; the RF Laser Setup Menu codes are strictly for  
configuring the reader. If you did not hear two beeps, try scanning the code  
again, until you hear the two beeps. If you've never scanned bar codes before,  
read the scanning instructions on page 8 before continuing.  
2. Next, choose the parameter you want to change an option for, and scan its  
code (i.e. Code 3 of 9, or Postamble). You should hear two beeps if you  
scanned correctly.  
3. Then, choose the option you want to change from the list below the  
parameter bar code you just scanned, and scan the number on the barpad  
that corresponds to that option. For example, if you scanned the parameter  
“Codabar” and wanted to “Enable Codabar”, you would scan the number  
0 on the barpad.  
4. Now scan End Setup (at the top-right corner of the Reader Setup Menu to  
complete the setup exercise. If you scanned correctly, you'll hear three beeps.  
Continue scanning topics and options until you've made all the changes you  
desire, and then scan End Setup to complete setup. If you are planning to use  
several RF Laser scanners with one base station, pay attention to the Set ID  
parameter.  
The next several pages will show you all of the various RF Laser options.  
Default settings are shown in bold in this manual and marked with an * on the  
RF Laser Setup Menu.

by scanning the Setup Menu.  
All Lasers and associated Base Station must be set to the same  
channel. If you have more than one RF Laser per Base Station, you  
must set a unique ID in each RF Laser. (See SET ID.)  
The Laser channel must match the channel on the Base station. See

Enabling Start/Stop character transmission means that the RF Laser Reader  
will transmit the * Start/Stop characters to your computer along with the data.  
For example, data of 1234 would be transmitted as *1234*.  
Enabling the Mod 43 Check Digit requires the units position of your data to  
match the calculation for the check digit explained in Appendix C.  
10  
 
If you've enabled the check digit, enabling Check Digit transmission causes  
the reader to transmit it to your computer along with the bar code data.  
"Caps Lock ON" means that for all codes lower case letters read as data will be  
transmitted as upper case, and upper case as lower. Numbers, punctuation &  
control characters are not affected. This applies to Code 128 and Code 93 also.  
"Caps Lock OFF" means that letters will be transmitted exactly as read.

For more information on UPC and EAN, see following page and Appendix H.  
Enabling supplements allows you to read 2 and 5-digit supplemental codes  
used with magazines and paperbacks. This disallows right-to-left reading of  
UPC codes, to assure that the supplement doesn't get skipped.  
Use setting 2 to enable reading of the 2 and 5 digit UPC/EAN supplements  
commonly found on magazines and paperback books. Use this setting to force left  
to right reading of UPC codes, assuring that the supplement code is not missed.  
This setting also allows for reading of the UCC/EAN 128 Extended Coupon Code.  
The Extended Coupon Code consists of a UPC code with a NSC of 5 or and EAN  
code with a country code of 99 along with a Code 128 supplemental code to the  
right. This setting allows you to read the Code 128 supplement with the  
UPC/EAN, providing the UPC has a NSC of 5 or the EAN code has a country  
code of 99. Without the correct NSC or country code, the Code 128 portion will be  
ignored; UPC code with an NSC of 5 or EAN codes with country code of 99 will  
not be read unless there is a readable Code 128 supplemental code read also.  
UPC-E Compressed Format transmits UPC-E codes as is; Expanded  
Format adds zeros to make them the same length as UPC-A.  
11  
 
UPC-E can be used in either normal UPC-E format (implicit NSC of 0) or  
UPC-E1 format (NSC of 1). UPC-E1 is enabled by scanning 2 of 5 Code and  
8 (9 disables UPC-E1). It is very easy to partially read EAN-13 as UPC-E1, so  
don't enable UPC-E1 if reading EAN-13.  
If you wish to transmit UPC-A data in EAN-13 format, (an added leading 0  
for the USA's country code), scan Terminator Character and F. Scanning E,  
the default, sets UPC back to no country code transmitted.  
ISBN, International Standard Book Numbering, bar codes are EAN-13 codes  
with a 5 digit supplement. If the first three digits are the "Bookland" country  
codes of 978 for books or 977 for periodicals, then you can enable trans-  
mission of EAN-13 bar codes in the ISBN format. Suppose you scan an EAN-  
13 with 5-digit supplement which is a bar code of 978055337062153495. It  
would be transmitted in ISBN format as 0553370626 (as of Jan.1, 2006, the  
correct ISBN format is the EAN-13 bar code with the 5 digit supplement).  
055337062 are the first nine digits of the ISBN format, and 6 is the newly  
calculated Mod-11 check digit.  
To enable the transmission of the ISBN format, scan Terminator  
Character and D. Scanning C, the default, disables conversion to ISBN  
format back to regular EAN-13 format.

Enabling the Check Digit requires the data's units position to match the  
calculation for the check digit explained in Appendix F. If you've enabled the  
check digit, enabling Check Digit transmission causes the reader to transmit it  
to your computer along with the bar code data.  
13  
 
2 of 5 Data Length  
2 of 5 Code is so susceptible to interpreting partial scans as valid reads  
that the RF Laser uses fixed-length data as a safeguard. To choose a data  
length, scan it as a two-digit number using the Barpad Table. For example, to  
select 8-digit data length, you would scan a 0 and then an 8. Because  
Interleaved 2 of 5 is required to be an even number of digits in length, you  
must use an even number. If you're unsure of your bar code length,  
temporarily set the length to 00, read a bar code, and count its digits and then  
set it to the actual length. DO NOT PERMANENTLY SET THE 2 of 5  
LENGTH TO 00 or you will get misreads!

Depending on your application, you may wish your RF Laser to transmit bar

or with no extra terminating character at all.  
If you need a terminator character other than CR or TAB, you can get it by  
specifying None here and then selecting your desired terminator character(s)  
specified in the Postamble (See Page 15).

Preamble  
A "Preamble" is a user-specified data string transmitted at the beginning of  
each bar code. For example, if you specify the preamble @@ and read data of  
123456, "@@123456" would be transmitted to your computer.  
14  
 
The default is no preamble. To select a preamble, scan up to 15 characters from  
the "FULL ASCII MENU" on the back of the RF Laser Setup Menu, and then  
scan SET when you're done. To return to the no preamble setting, scan Clear  
here instead of scanning SET or any characters from the FULL ASCII MENU.  
You can trim 1-15 leading characters from bar code codes by scanning a ~  
(tilde -- ASCII 126) followed by a single digit, 1 through F, as part of the  
Preamble. (Bar codes that are shorter than the amount-to-trim are transmitted  
with no trimming.) Consider the examples in the following table to  
understand how trimming works:

You can also trim selectively by bar code type. For example, you can trim 2  
characters from Code 39 and a different amount from other bar code outputs. This  
is done by using the bar code ID character in conjunction with the tilde (~). A  
preamble of ~b2~c1 says trim 2 characters from the front of Code 39 output and  
trim 1 character from the front of UPC-A. Refer to the Code 128 parameter on  
page 12 for a list of the ID character associated with each bar code type.  
A final use of the Preamble/Postamble is to enter a minimum/maximum length  
check for bar code data read. Use the Preamble or Postamble by entering  
|nnmm where "|" is ASCII 124, "nn" is the two digit minimum to be read and  
"mm" is the two digit maximum to be read.  
Postamble  
"Postamble" refers to a user-specified data string transmitted at the end of each  
bar code. For instance, if you specify the postamble @@ and read data of  
123456, "123456@@" would be transmitted to your computer.  
The default is no postamble. To select a postamble, scan up to 15 characters  
from the "FULL ASCII MENU" on the back of the Reader Setup Menu, and  
then scan SET when you're done. To return to the no postamble setting, scan  
CLEAR here instead of scanning SET or any characters from the FULL  
ASCII MENU.  
You can trim 1-15 trailing characters from bar code codes by scanning a ~ (tilde  
-- ASCII 126) followed by a single hex digit, 1 through F. (Bar codes which are  
shorter than the amount-to-trim are transmitted without trimming.) Consider the  
examples in the following table to understand the options of the Postamble:  
15

Bar codes that are shorter than the sum of the Postamble trimming and  
Preamble trimming will be transmitted without trimming. Selective trimming  
and min/max bar code data is also supported through Postamble specifications,  
(See Preamble above for complete details).  
Characters  
This setup option allows you to output ASCII characters different from the  
ones scanned.  
For example: Suppose you want the RF Laser to output a hex 92 character  
every time you scan a 1 (hex 31); you want to remap hex 31 to hex 92, (If  
you're using 8 data bits, output of 80-F8 codes is possible.)  
1) Scan the Start Setup Bar Code  
2) Scan the Characters Bar Code on the Setup Sheet.  
3) Scan 3 1 and 9 2 to output hex 92 when reading a "1".  
4) Scan up to 7 other pairs of character reassignments.  
5) Scan Set when complete.  
6) Scan End Setup to exit setup mode.  
Hex values for each character code are shown on the Full ASCII Menu. The  
equivalent decimal values are also shown for each character.  
You can also eliminate characters by reassigning hex codes to FF. For  
example, to strip all $ (dollar sign) characters from transmission, you would  
follow the above instructions and scan 2 4 F F in step 3.  
Set ID Character  
The ID is used to differentiate between multiple RF Lasers attached to the  
same Base Station.  
Multiple scanners on one base station require each scanner to be set to a  
unique ID of 0,1,2,3.....9. Scan Set ID Character and then scan 0-9 for each  
scanner, giving each a different ID of 0-9.  
Link Test Code  
This is a code to test the transmission link between the RF Laser and its Base  
Station, without transmitting data. You can use this to be sure you are in range  
and able to hear the base station beeping. No data is transmitted. Do not enter  
16  
 
the Setup Mode when performing the link test. This code is the same as the  
"Clear Buffer" code on the Barpad Menu.  
Reset  
Once you are in the Setup Mode, don't scan Reset unless you're sure you want  
to restore the RF Laser to its default settings (as described on page 7), erasing  
all changes you've made.  
DIFFICULT CODE SETUP OPTIONS  
Aiming Laser Dot: Sometimes it is difficult to see the laser beam and know  
you are on the bar code, especially if you are attempting to read outdoors in  
direct sunlight. The laser can be outputted as a brighter dot for a few seconds,  
allowing the user to place the dot in the middle of the bar code; then the laser  
beam starts sweeping for the read. As shipped, the laser beam never forms an  
aiming dot, but you can program a number of seconds that you wish the  
aiming dot to appear before the sweeping beam by scanning the following:  
Scan Start Setup  
Scan Aiming Dot Duration  
Scan 1 digit from the Barpad Table. The default is 0, for no aiming  
dot. You can enter any 1 digit number from 0 to 9 (9 gives you 9  
seconds). Typically you will want to set it to a 1 second (scan 1) or a  
2 second (scan 2) aiming dot.  
Scan End Setup  
4-second beam: Another option with problem reading conditions is to increase  
the length of the time the scanner attempts to read, from the default 2-second  
beam to a 4-second beam. To select the 4-second beam:  
Scan Start Setup  
Scan 2 of 5  
Scan F to select the 4-second beam  
Scan End Setup  
To return to the default 2-second beam, scan E instead of F.  
Automobile VIN READING:  
There is special support for reading automobile Vehicle Identification Numbers,  
VIN, remotely from the computer. You may want to use the aiming dot above too.  
"Delayed Transmission": is a feature which allows the user to leave the  
computer, (perhaps being operated by someone else), go to the location of the  
car, scan the VIN with the first trigger pull, return to the computer, be certain  
that the screen and cursor are properly positioned, and then pull the trigger  
again for transmission. The first trigger pull scans and stores the bar code. The  
second trigger pull transmits the data, permitting the user to be sure the cursor  
is properly positioned. To change the reader to “Delayed Transmission”:  
17  
 
Scan Start Setup  
Scan Terminator  
Scan B to select "delayed transmission"  
Scan End Setup  
To disable "delayed transmission", repeat the above substituting A for B.  
"Difficult Code 39 Reading": This feature facilitates reading of he VIN  
number on automobiles, which is often a difficult-to-read bar code, especially  
reading through a windshield. VIN numbers are long, often weathered, often  
dirty, and challenging to read.  
To enable the more aggressive Code 39 algorithms necessary to read  
windshield VINs:  
Scan Start Setup  
Scan 2 of 5 Code  
Scan D for windshield reading  
Scan End Setup  
To return to the default Code 39 decode algorithms, scan B instead of D.  
"Double-scan checking": When reading a VIN, you will also want to disable  
double scan checking. The reader’s default is to not output or beep until it has  
two successive identical decodes. This is an acceptable safeguard with most  
codes, but with VIN numbers read through a windshield, you will have to  
deactivate double scan checking to get timely reads.  
Scan Start Setup  
Scan Code 39  
Scan F to disable doubles scans.  
Scan End Setup  
To enable double scan checking, scan E instead of F.  
Don’ forget the common sense things you can do to facilitate reading the VIN:  
1) Be sure the window on the laser scanner is clean.  
2) Be sure the windshield is wiped before of reading.

Host Controlled Acknowledge  
"None" means that Base Station will immediately transmit an acknowledgement to  
the RF Laser from which it has just received transmitted data, (without waiting for  
a response from the host computer program.)  
19  
 
If you want the host computer program to analyze the data and to send back  
different beep patterns to the laser scanner, enable Host Controlled  
Acknowledge. With this parameter enabled, the data is passed to the computer  
and no acknowledgement is sent to the scanner until the host computer replies to  
the base station with one of three possible ASCII codes: ACK (ASCII 06), BEL  
(ASCII 07), DC2 (ASCII 18). Upon receipt of these codes from the host  
computer, the base sends a signal back to the transmitting laser scanner that  
causes it to emit beeps as follows:  
ACK - one short beep in laser  
BEL - two longer low pitched beeps  
DC2 - three longer low pitched beeps  
This allows the host computer program to give limited feedback to the scanner  
operator.  
Test the RF Laser with your computer  
If you are connected by USB interface, or if you have a serial reader and are  
using PortKey on a PC, you should be able to scan the bar code on the next  
page, hear a beep and see data displayed on the computer's screen. First get  
your computer to some program where you can type and see it on the screen,  
(i.e. Notepad). Now scan the TEST LABEL below. Your screen should show:  
TEST LABEL  
If you can't read the TEST LABEL, see the Scanning Techniques back on page  
8. If you don't get a beep, try moving closer to the Base Station and moving  
the scanner closer or farther away from the bar code. If you get a beep but no  
data displayed:  
•
•
Check your connections  
If you are connected to serial port and aren't using PortKey, you will  
need to use a communications program; or use the WDR Serial Test  
Program distributed with your serial reader. The program is for  
Windows only.  
If you are using the WDR Serial Test Program, follow these guidelines:  
•
•
Make sure the serial parameters on your Base Station match those  
used by your computer.  
Make sure you are connected to a valid serial port.  
If you still are having problems, see the Troubleshooting Section.

Radio Considerations  
Operating Instructions  
Operational Details  
The RF Laser:  
1. chirps on a "good read" or successful scan while turning off the scanner  
beam, and  
2. beeps loudly when it gets the acknowledgement back from the Base  
Station that it has received the data.  
The yellow light on the back of the scanner indicates that it is transmitting.  
You will see up to four transmission attempts before the unit goes to sleep and  
waits for you to pull the trigger again. The green light indicates that it has  
received the acknowledgement from the Base Station. After four unsuccessful  
tries of transmitting to the base without an acknowledgement, the scanner  
chirps 8 times and goes to sleep waiting on the operator to move closer to the  
base station and pull the trigger again for a transmission retry. After going to  
sleep on an unsuccessful read, when the trigger is pulled again, the scanner  
beam doesn't turn on for reading; instead, the unit beeps three times to indicate  
is re-transmitting and just transmits again. This sleep and retransmission cycle  
is repeated until the acknowledgement is received or the buffer is deliberately  
cleared. In this way, no scanned data is lost, even though you have wandered  
out of range of the Base Station. Until the pending data acknowledgment has  
been received, pulling the trigger will only retransmit and not activate the  
scanning laser beam for additional reading.  
If you are out of range and want to clear data in the scanner's buffer waiting to  
be transmitted again, by pulling the trigger and holding it down for 30 seconds,  
the buffer will be cleared and the scanner will emit 3 low pitched beeps.  
Range  
The operational range of 500 feet is far greater than is practical to operate  
blind from the PC. However, unless the unit becomes defective, you should  
experience excellent transmissions in almost any environment.  
Avoid locating the Base Station next to a 900 MHz phone. Raise the Base if  
you are having any range issues.  
22  
 
Accumulate Mode  
Accumulate Mode is an option (which can be enabled or disabled using the RF  
Laser Reader Setup Menu's Code 39 section) allowing the reader to  
accumulate multiple bar codes in its buffer, then transmit them to the computer  
as if they had been a single bar code. This is useful for entering quantities and  
other variable data. A small laminated barpad card is provided with each  
reader ordered to aid in entering variable quantities.  
It works with Code 39 only, and can't be used with a check digit. When the  
reader reads a bar code with a leading space, it beeps and buffers the data  
without transmission. It continues to read and buffer bar codes (up to 40  
characters) until it reads a bar code without a leading space. Then the entire  
buffer (including that last code) is transmitted as one long bar code. A bar  
code of a double minus (--) sign clears the buffer. Scanning a backspace code  
($H) backspaces in Full ASCII mode. A handy code for Enter (as seen on the  
"Barpad" below) is a Start/Stop only. (No data.) The code to use for testing the  
transmission link between the RF Laser Scanner and the RF Base Station is the  
CLEAR BUFFER code (the same bar code as titled Link Test on the Setup  
Menu. It will cause beeps to be heard, but no data will be transmitted to the  
computer -- testing blind with no computer consequence.  
This numeric "Barpad" illustrates Accumulate Mode. Scan 5, 3, 8, and Enter.  
The reader transmits a single message of 538.

Function/Control Key Support  
The RF Laser can also transmit key sequences for function, control, alt  
(command and option keys on Macs), cursor and shift keys, for ease of use  
with the many software packages using these keys for menus or commands.  
You can include these codes in other bar codes, or you can scan these  
“keystrokes” into your Preamble or Postamble in order to add them to every  
scan from your reader. You must have Full ASCII Code 39 enabled on your  
reader (this is the default setting). Scan the corresponding bar code (or pairs of  
codes for Pg Up, Pg Dn, Home, etc) from the Full ASCII menu to emulate the  
chosen key.

* refers to the keys on the Number pad on the far right side of a PC keyboard.  
To emulate any of the keys above, scan the appropriate bar code from the  
FULL ASCII MENU. For example, to emulate the f5 key, scan the ENQ bar  
code.  
24  
 
Simply scan the correct bar code(s) from the FULL ASCII MENU. For  
example, if the WDP reads the bar code SOH (ASCII 001 -- a control-A) from  
the FULL ASCII MENU, it will transmit an F1 key.  
Shift, Ctrl and Alt keys require three sequences:  
1) The ON code generated when the Shift, Ctrl or Alt key is pressed.  
2) The other key to be used in conjunction with the Shift, Ctrl or Alt key.  
3) OFF code generated when the Shift, Ctrl or Alt key is released.  
(For example, to create a Control C bar code: use Control ON, C, and Control  
OFF. To put Control C in a Preamble or Postamble, scan from the Full ASCII  
Menu: Control ON, C, and Control OFF).  
Function keys F11 and F12  
Function keys F11 and F12 require two bar codes to be scanned to make these  
functions keys. The F11 key is created by combining the Null and SOH. The  
F12 key is created by combining the Null and the STX.  
Windows Key  
The Windows key on a Windows keyboard is transmitted by scanning 4 bar  
codes - NULL and C for Windows On (pressing down) and NULL and D for  
Windows Off (releasing the key).  
Command and Option Keys on Mac USB Keyboards  
When you have a WDP Reader attached to a Macintosh Computer's USB port,  
to emulate the Command key, use the Windows key ON/OFF bar codes  
NULL, C (Command ON) and NULL, D (Command OFF) For the Option Key  
ON/OFF use RS (Option On) and US (Option Off).  
Transmitting any ASCII character using its 3-digit ASCII code  
You can also transmit any ASCII character from 000 to 255 by emulating the  
PC technique of typing a character's ASCII number on the numeric pad while  
holding down the Alt key. For example, to transmit ASCII 250, you would  
scan the bar codes for:  
Full ASCII Menu

Recheck all the connections. Get close to the Base Station. Try reading  
the Link Test bar code, following the steps for scanning on page 8.  
•
If you hear two beeps, but see nothing on the screen, and you are  
reading the pocket card, you must read the ENTER bar code to have  
anything transmitted. Any Code 39 or 128 bar code with leading spaces  
(such as the Barpad on page 23) will not be transmitted to your  
computer until you read a bar code without a leading space. Try  
reading the Test Label on page 21 as an example of a known good label  
without a leading space. If you have bar codes with leading spaces in  
them, and you want them transmitted, you must disable Accumulate  
Mode using the Setup Menu.

Recheck the installation instructions beginning on page 4 to make sure  
all cables are properly connected.  
•
If you're trying to read Code 39 bar codes with leading spaces (such as  
the Barpad on page 23) and have enabled Accumulate Mode, those bar  
codes will not be transmitted to your computer until you read a bar  
code without a leading space. Try reading the Test Label on page 21 as  
an example of a known good label.  
•
•
If you're using PortKey on an IBM-compatible, verify that the readers  
matches the program's COM port, baud rate, data bits, stop bits, and parity  
If you're using your own software to read the serial port, verify that the  
problem is not in your software. Run the WDR Serial Test Program  
that shipped with your reader and see if it gets any data on the screen  
when you read a bar code.  
•
Use a "null modem" connector to test switching pins 2 and 3 on one or  
more serial cables, or use a breakout box to modify your cable(s).  
The reader doesn't beep when you try to read your bar codes.  
•
Make sure the power adapter is plugged in.

Appendix A  
Changing Jumpers and Channels  
You may want to change the channel on the Base Station or you may want to  
set the unit to use a Serial Y Cable. To do so, open up the case.  
Turn your Base unit upside-down and unscrew its single Phillips screw. If you  
don't completely remove the screw you can use it as a lever to pull up on the  
cover, otherwise insert a fingernail, credit card edge or small screwdriver  
blade into the gap between the base and side of the case. Gently use it as a  
lever to lift up the edge of the base, then grasp the edge of the base and open it  
outward like a door.  
This exposes the reader's circuit board, as shown on the next page. When  
you've finished examining or changing jumper settings, put the reader case  
back together by reversing the steps illustrated on this page.  
To change the Channel (0-9 for USA and Canada), unplug the power supply  
and use a small flat head screwdriver to move the rotary switch shown below  
to the number of the channel you desire. Now simply put the case back  
together and plug in the power supply. You should see channel number set+ 3  
green flashes on the base's LED; i.e. channel 0 setting will flash 3 times --  
channel 6 setting will flash 9 times.  
29  
 
Serial Users, if you are going to use the Serial Y Cable (F45-1), you will need  
to change the JP2 (Jumper 2) from S to Y. This permits Half Duplex  
transmissions and interface between a host and terminal.  
30  
 
Appendix B  
Recharging the Batteries  
The LZ400-RF Laser has a rechargeable lithium ion battery built-in.  
When not in use, the RF Laser should be plugged into the supplied, regulated  
Worth Data 5V power adapter (DO NOT USE ANY Supply Except Worth  
Data), so that it will always be recharged. The built-in recharger is a smart  
charger, so you can't overcharge the battery and ruin it. A full charge takes  
about 3 hours.  
If you ordered the USB interface, the F10 power supply included with the laser  
is used for recharging, since USB does not usually require the power supply to  
power the Base Station (see page 6). The serial configuration will require a  
second Worth Data 5v power supply if you want to keep the Base Station  
powered up at all times. You can get by with one power supply by simply  
unplugging the Base Station so you can recharge the RF Laser Reader.

Appendix C  
Specifications for Code 39  
Code 39 (or Code 3 of 9) is the de facto standard of non-retail American  
industry. It is widely used in the automotive industry (AIAG specifications) as  
well as in government and military applications (LOGMARS specifications).  
Code 39 is flexible, features a large character set, variable data length and  
density, and bi-directional readability. Code 39 is extremely accurate;  
substitution errors are almost nonexistent. Its character set consists of  
numbers 0 through 9, upper case A-Z, and characters Space, $, %. / + and -.  
The name "Code 39" comes from both the fact that its  
character set originally contained 39 characters (it now  
has 43) and from its structure. Each character is formed of  
three wide and six narrow elements, made up of five bars  
and four spaces. Code 39's density can vary from a low  
of .75 characters per inch (cpi) to a high of 9.4 cpi.  
There should be a ¼" "quiet zone" (white space) to  
*C39*  
the left and right of the bar code.  
Code 39 uses an asterisk (*) as a start and stop character. This character must  
precede and follow the data in the bar code. The RF Laser Reader gives you

Code 39 Advanced Features and Functions  
Mod 43 Check Character  
Standard Code 39 can be printed with a "Mod 43 Check Character". This  
Mod 43 check character cannot be used with Full ASCII Code 39. The check  
character is derived by assigning a value to each character in the data to be bar  
coded from the table as follows:

Table C-1. Mod 43 Check character calculation for Code 39  
Here is an example to illustrate how the check character is calculated for bar  
code data of 123XYZ:  
1. Take the sum of the values assigned to each character:  
1 + 2 + 3 + 33 + 34 + 35 = 108  
1
2
3
X
Y
Z
2. Divide the sum by 43: (thus the name modulus 43)  
108/43 = 2 with a Remainder of 22  
3. Find the character corresponding with the remainder.  
M (value 22) is the CHECK CHARACTER  
The data becomes 123XYZM, with M added as the Mod-43 check character.  
33  
 
Full ASCII Extension to Code 39  
"Full-ASCII Code 39" expands the Code 39 character set to include all 128  
ASCII characters. Symbols 0-9, A-Z and punctuation characters. and - are  
identical to their Code 39 representations. Lower-case letters, additional  
punctuation characters and control characters are represented by sequences of  
two Code 39 characters.

Table C-2. Full ASCII Table  
34  
 
Appendix D  
Code 93 Specifications  
Code 93 is variable length, continuous, bi-directional, compact code. Code 93  
is an alphanumeric bar code, which consists of 43 data characters (0-9,A-Z,  
$/+%.- and Space), 4 control characters, and a unique start/stop character.  
The entire set of 128 ASCII characters is represented in Code 93 using  
combinations of control characters and data characters.  
The control characters are  
,
,
, and  
. Full ASCII 93 is created by  
pairing these control characters with normal data characters. It is almost identical  
to the pairings for Code 39; Code 39 uses $M to produce a Carriage Return  
(ASCII 13) character -- Code 93 uses  
M to produce the Carriage Return.  
Code 93's two built-in check digits greatly minimize the possibility of reader  
substitution errors. These check digits are never transmitted by the bar code  
reader. Code 93's Start and Stop characters are also never transmitted.  
If you have not decided which bar code type to use for your application and  
are considering using Code 93, while we agree that Code 93 is an excellent  
code, we believe that Code 128 is generally preferable because:  
1. Code 93 does not have the numeric compression capability that  
128 does, and  
2. Code 93 requires pairings to make all Full ASCII characters while  
128 does not.  
35  
 
Appendix E  
Codabar Specifications  
Codabar is widely used in libraries, blood banks, the cotton industry and  
transportation industries. Its' character set consists of numbers 0 through 9,  
and punctuation characters + . - / : and $. Symbols a, b, c, d, t, n, * and e are  
used as start and stop characters. Characters are constructed of four bars and  
three spaces.  
Codabar is a numeric-only code, but different  
combinations of start and stop characters can be used to  
identify different types of labels. Codabar's variable  
data length and extremely low error rate make for a  
versatile bar code.  
a12345b  
Codabar start/stop transmission  
The Codabar section on the RF Laser Reader Setup Menu lets you determine  
whether Codabar start/stop characters are transmitted or not. If you are  
varying start/stop characters with different types of labels, you'll want to  
"Enable Stop/Start character Transmission". Start/stop character  
transmission can also be helpful if you want your program to differentiate  
between data coming from the RF Laser Reader and data coming from the  
keyboard. If neither situation applies, you'll probably want to disable it.  
36  
 
Appendix F  
Code 128 Specifications  
Code 128 is a very powerful bar code, combining an extensive character set  
and variable length with compactness and error checking. The character set  
contains all 128 ASCII characters with each character made up of three bars  
and three spaces. Each element (bar or space) varies from one to four units in  
width, totaling 11 units of width per character. Code 128 contains two levels  
of error checking:  
•
•
Each character is checked for internal parity, and  
The last character is a checksum.  
Code 128 has three subsets, A, B and C. Subset A  
contains alphanumeric characters and unprintable  
control characters, subset B contains alphanumeric  
characters plus printable control characters and subset C  
contains only numeric characters and uses a 2-character  
encoding scheme to create a more compact bar code.  
Code 128 uses an internal Mod 103 check character that  
12345  
is not displayed by the bar code reader. Code 128 bar codes can be made up of  
only one subset or may be a combination of several.  
The Code 39 features of Accumulate Mode, Caps Lock ON and Caps lock  
OFF also apply to Code 128.  
UCC-128/ EAN-128  
UCC-128/EAN-128 Code is a subset of Code 128 adopted by the UCC and  
EAN council’s for use as a shipping label symbology. UCC/EAN-128 bar  
codes always start with a Function Code 1 character. In addition, all variable  
length fields are terminated by a Function Code 1 character unless they are the  
last field in the bar code.  
The RF Laser Reader outputs the following for the special function codes and  
start sequences:  
]C1 Start C/Function Code 1  
^] (GS) Function Code 1 as a variable string terminator  
If UCC/EAN 128 is enabled, the reader looks for the Start C/Function Code 1  
to indicate a UCC/EAN 128 bar code.  
The UCC Serial Shipping Container Code specification calls for a 19 digit  
UCC/EAN 128 code with an additional Mod 10 Check digit (20 digits in all).  
37  
 
The Mod 10 Check digit is calculated the same as the Interleaved 2 of 5  
example in Appendix G. It is the data length as well as the MOD 10 check  
digit that distinguishes the UCC Serial Shipping Container Code from other  
UCC /EAN 128 bar codes.  
UCC/EAN 128 is enabled by scanning the appropriate bar codes on the RF  
Laser Reader Setup Menu. If UCC/EAN 128 is enabled, you will be able to  
read both standard Code 128 bar codes as well as the UCC/EAN 128 bar codes  
with the Function 1 character and the Mod 10 check character.  
UCC 128 Shipping Container Code  
The UCC 128 specification is used extensively by the retail industry. If you  
have a requirement for a UCC 128 Serial Shipping Container bar code, be  
sure to follow the specification as closely as possible as many vendors will  
impose fines for non-conformance. For more information on UCC/EAN 128,

Appendix G  
Interleaved 2 of 5 Code  
Interleaved 2 of 5 Code is a numeric-only, even-number-of-digits bar code. It is  
widely used in warehouse and industrial applications. A combination of five  
elements, two wide and three narrow represent each character. Odd-number  
position digits are encoded in the bars, even-number positions in the spaces.  
Interleaved 2 of 5 Code is so susceptible to partial scans being  
interpreted as valid reads that we recommend at least one of the  
following safeguards:  
123456  
•
Use one length of I 2 of 5 code. Using one length of data allows  
you to tell the RF Laser Reader to look for one length of I 2 of 5  
code only. By default, the RF Laser Reader is set to look for a 6  
digit I 2 of 5 code but you can set the length to something different  
using the RF Laser Reader Setup Menu. Setting the length to 00  
digits allows variable length bar codes scanning but also  
dramatically increases your chance of a mis-read.  
•
Use a check digit. Worth Data’s LabelRIGHT printing program  
automatically calculates and prints a check digit upon request using  
the method below:  
Interleaved 2 of 5 Mod 10 check digit calculation  
1. Assume that the bar code data is 1987.  
2. Starting with the least significant digit (in this case, a 7), label the  
digits alternatively even and odd.  
7 - even  
8 - odd  
9 - even  
1 – odd  
3. Take the sum of the odd digits:  
8 + 1 = 9  
4. Multiply the sum of the even digits by 3:  
(7 + 9) x 3 = 48  
5. Add the results of steps 3 and 4:  
9 + 48 = 57  
39  
 
6. Subtract the result of step 5 from the next highest multiple of 10:  
60 - 57 = 3  
7. The checksum becomes the low-order digit:  
19873  
8. Because the data now has an odd length, a leading zero is added,  
for the final result of  
019873  
40  
 
Appendix H  
UPC Specifications  
UPC symbols are found on almost all grocery  
products and many other retail items. The UPC  
code most people are familiar with (UPC-A) is a  
fixed-length (12 digits) numeric only code, with  
the first digit controlled by UPC coding  
assignments and the last digit a checksum. UPC-  
E and UPC-E1 are variations of the standard  
UPC-A code. Each digit is constructed of two bars and two spaces. UPC has  
very precise standards of code size, structure, and numbers to be used.  
EAN is an international superset of UPC. EAN-13 has  
13 digits, with the first two digits representing a  
country code. The final digit is, as with UPC, a check  
digit. EAN-8 is a shorter version on the EAN-13 code  
containing seven data digits and ending again with a  
checksum.  
The exact UPC/EAN symbol specifications are available from:

Specifications are also available via the Internet at:  
http://www.uc-council.org  
Keep the following guidelines in mind when printing UPC bar codes:  
•
If you plan to use a "supermarket-type" in-counter scanner to read  
the codes, specify a bar code height of at least .9" for an optimal first  
read rate.  
•
Make it an early practice to observe the numbering conventions of  
the GS1 US. Do not label unmarked merchandise with a bar code  
whose numbers may conflict with those already assigned. If products  
with these numbers are not in your store now, they are likely to be in  
the future, causing conflicts in your inventory system.  
41  
 
•
The leading Number System Character, (the first number of the 11  
digits to be entered) should conform to these UPC assignments:  
0,6,7,8 Regular UPC 12 digit codes with numbers assigned by  
the GS1 US. (Do not use 0 as the leading number for in-  
store marking).  
2

5
Store-marked random weight items of meat and produce.  
Reserved for National Drug Code and Health Related Items.  
Use this leading digit for in-store marking of non-food items.  
Reserved for coupons. Do not use this today, or you will not  
be able to process coupons through your system tomorrow.  
UPC 2 and 5-character supplemental codes  
The UPC standards include the addition of a  
2 or 5-character supplemental code used  
with magazines and paperback books. To  
read the supplements, you must first enable  
them using the RF Laser Setup Menu.  
NOTE: Enabling the supplements disallows  
the reading of UPC codes from right to left  
to assure that the supplement does not get missed.  
ISBN Specifications  
ISBN (International Standard Book Numbering) bar codes are essentially  
EAN-13 with a 5-digit supplement, where the first 3 digits are the Bookland  
country codes of 978 for books and 977 for periodicals. Although the bar code  
contains 18 characters, the ISBN format uses only 9 of them, along with a  
newly calculated Mod-11 check digit. For example, a bar code containing the  
numbers 978055337062153495 would transmit as 0553370626 in the ISBN  
format. The RF Laser Reader has the option of transmitting in the ISBN  
format.

The UPC/EAN checksum character  
The last character in a UPC-A, UPC-E, UPC-E1, EAN-13 or EAN-8 bar code  
is the checksum. For reference, these are the methods of calculation:  
Checksum calculation for UPC-A, EAN-13 and EAN-8  
Use Worth Data’s phone number (it's not a real UPC-A code) as sample data:  
18314589938  
Assign even and odd positions, starting at the right and moving left:  
8
3
9
9
8

odd even odd even odd even odd even odd even odd  
1. Starting with the leading digit, 8, take the sum of all the characters in  
the odd positions.  
8 + 9 +8 + 4 + 3 + 1 = 33  
2. Multiply the result of step 1 by 3.  
33 x 3 = 99  
3. Now take the sum of all the even-position characters.  
3 + 9 + 5 + 1 + 8 = 26  
4. Add the result in Step 2 to the result in Step 3.  
99 + 26 = 125  
5. Subtract the result from the next higher multiple of 10.  
Next higher multiple of 10 over 125 = 130  
130 - 125 = 5  
5 is the Modulo-10 check character. The data to be printed  
becomes:  
183145899385.  
This same formula is used for EAN-13 (using the 1-12 digits) and EAN-8  
(using the 1-7 digits).  
43  
 
UPC-E Checksum Calculation  
Use the sample data of 123456 to demonstrate the UPC-E checksum  
calculation:  
1. The 6 digit UPC-E code is converted to a 10-digit code, using an  
expansion scheme based on the sixth digit:  
If the code  
ends in:

Because the sample UPC-E code ends in a 6, the insertion digits 0000 are  
inserted at the sixth digit (insertion position 6):  
1234500006  
2. Add the Number System Character of 0 to the sample data:  
01234500006  
3. Use the UPC-A check digit calculation described in the previous  
section to produce a check digit as if it were a UPC-A code. The  
check digit for the sample data is:  
5
4. The complete 8 digit code consists of the Number System Character,  
the original 6 digit code and the check digit:

Appendix I  
MSI/Plessey Specifications  
Plessey is a variable length numeric only bar code. MSI Bar Code is a  
variable length, numeric-only code with an automatically appended Modulus  
10 check digit. MSI is sometimes called Modified Plessey Code. If the user  
specifies an additional check digit, the MSI code can be 14 digits long,  
otherwise it has a maximum length of 13 characters. This is how the MSI  
check digit(s) are calculated:  
The MSI Mod 10 check digit is calculated as follows:  
The example bar code data is:  
82345  
1. Form a number from the odd positions, starting in the units position.  
835  
2. Multiply the new number by 2  
(835) x 2 = 1670  
3. Add the digits of product  
1 + 6 + 7 + 0 = 14  
4. Add the even digits of the original number to the result in 3  
2 + 4 + 14 = 20  
5. Subtract the result from the next highest multiple of 10  
20 - 20 = 0  
6. New Check Digit  
0
7. Data with check digit is:  
823450  
45  
 
The MSI Mod 11 check digit is calculated as follows:  
The example bar code data is:  
943457842  
1. Assign a checking factor to each number, starting with the units  
position of the number (in this example, the 2) up to the highest  
order position (the 9). Use checking factors of:  
2,3,4,5,6,7,2,3,4,5,6,7...  
2. Multiply the checking factor with its assigned number and add the  
products:  
4 + 12 + 32 + 35 + 30 + 28 + 6 + 12 + 36 = 195  
3. Divide the sum by 11  
195/11 = 17 remainder 8  
4. Subtract remainder from 11  
11 - 8 = 3  
5. New Check Digit  
3
(If the remainder is 10, no check digit is added.)  
6. Data with check digit is:
