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 will not work with 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 will need a powered
USB Hub. 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®usually findsthe 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.

4
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.

5
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.

9
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
0on 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.

RF Laser Setup Parameters
Channel
Default Channel 0
• The default Channel is always shipped as 0. There are 10 channels
in the USA and Canada. The Channel for the RF Laser Reader is set
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
Appendix A for information on changing the channel on the Base
from the shipped default channel of 0.

Caps Lock ON C
Caps Lock OFF D
For information about Code 39 and Full ASCII Code 39, see Appendix C.
See page 23 for information about Accumulate Mode (this setting also
controls Code 93 and Code 128).
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.

11
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.

UPC-E Compressed C
UPC=E Expanded D
EAN-8 observes 9 & A above E
EAN-8 is forced to transmit 8 digits F
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 2to 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.

12
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.
Code 128
Disable Code 128 0
Enable Code 128 1
Disable UCC/EAN-128 2

Bar Code IDs transmitted E
Bar Code IDs not transmitted F
To enable a Bar Code ID character to be transmitted at the beginning of
each bar code read, scan E. The ID’s are as follows:
Codabar a I2of5 e 93 i Plessey x
Code 39 b 2of5 f UPC-E0 n LabelCode4 y
UPC-A c 128 g UPC-E1 o LabelCode5 z

For information about Codabar, see Appendix E.
CLSI format is a form of Codabar often used by libraries.
Enabling Start/Stop character transmission means that the RF Laser will transmit
start/stop characters to your computer along with data. If you're varying
start/stop characters with different label types, you'll want to enable
transmission.
2 of 5 Code
Enable Interleaved 2 of 5 0
Disable Interleaved 2 of 5 1
Enable Interleaved 2 of 5 Check Digit 2
Disable Interleaved 2 of 5 Check Digit 3
Enable Check Digit Transmission 4
Disable Check Digit Transmission 5
Enable Standard 2 of 5 6
Disable Standard 2 of 5 7
For information about Interleaved and Standard 2 of 5, see Appendix G.
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.

14
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!
Code 93
Enable Code 93 0
Disable Code 93 1
Enable Full ASCII Code 93 2
Disable Full ASCII Code 93 3
For more information on Code 93 see Appendix D.
Terminator characters (This applies to the BASE only)
CR (Enter) 0
Tab 1
None 2
Depending on your application, you may wish your RF Laser to transmit bar
code data to your computer with an Enter (carriage return), a Tab at the end,
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).
Beep Options
Decode and Acknowledge 0
Acknowledge Only 1
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.

15
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:
Bar Code Data Preamble Data Transmitted
123 XYZ XYZ123
12345678 ~3XYZ XYZ45678
12345678 ~9 12345678
12345 ~A 12345
123456 ~5 6
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, 1through 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:

16
Bar Code Data Postamble Data Transmitted
123 XYZ 123XYZ
12345678 ~3XYZ 12345XYZ
12345678 ~9 12345678
12345 ~A 12345
123456 ~5 1
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 31and 92to 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

17
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”:
