The LZ400-RF and the B78 Base Station have been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
•
•
•
•
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Shielded cables and I/O cords must be used with this equipment to comply with the relevant FCC regulations.
Changes or modifications not expressly approved in writing by Worth Data may void the user's authority to
operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and 2) this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1)
this device may not cause interference, and 2) this device must accept any interference, including interference
that may cause undesired operation of the device.
The laser used is a Class II Laser Product and has a 1.2 Milliwatts Output. To operate the laser scanner, aim the
scanner at the bar code, and pull the trigger. The light source will turn off, once a successful scan has occurred or 2.5
seconds has elapsed, whichever is first. Do not look directly into the laser light source with the trigger depressed;
avoid direct eye contact with the laser light source.
Introduction
The Worth Data RF Lasers have the following features:
1)
The LZ400-RF Laser Scanner for the USA and Canada. This laser has
a range of 500 feet 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 RF Lasers can communicate with one 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 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 Lasers can also operate
in the same room as the 701 RF Terminal.
4)
The R/F Lasers can read and discriminate between Code 39, Full ASCII
Code 39, Interleaved 2 of 5, Codabar, Code 128, EAN-13, EAN-8, UPCE, UPC-E1, UPC-A, MSI, LabelCode4, LabelCode5, Code 93 and
Plessey.
5)
The RF Lasers have a rechargeable lithium ion battery. The battery is
recharged with an included 5v power supply. Recharge time on fully
discharged batteries is 2 hours.
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 R/F Base Station with 1-10 RF Lasers.
2.
A Worth Data regulated 5V power supply with each Base Station and
Laser Scanner ordered. 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 laminated RF Laser Reader Setup Menu sheet.
5.
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
Before connecting to a USB port, first plug one of the Worth Data 5v
regulated power supply into the Base Station. (REMEMBER, any other brand
will damage the Base Station.) 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.
Now connect the USB port to the Base Station. The Base Station will be
automatically sensed 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 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 23. Now turn to page 8.
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.
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. See page 28 for a simple BASIC program to read the serial port
for testing purposes.
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 8
for the details of the pin-outs of the cables.
Turn to page 8 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.
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 8 for the
details of the pin-outs of the dual port serial cable.
Turn to page 8 to configure the your reader using the RF Laser Reader Setup
Menu.

Configuring the RF Laser Reader
for your computer and application
Find the 8 1/2 x 11" laminated RF Laser Reader Setup
Menu sheet and look it over. This simple menu lets you
easily configure the Radio/Freedom Reader 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 Reader 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 beams 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, or
the supplied Laser Setup Assist window, to "block off" bar codes
adjacent to whatever configuration bar code you need to read.
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, 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 Reader 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 9 before continuing.
2.
Next, choose the topic you want to change an option for, and scan its
code. Let's use Beep Tone, at the lower left corner of the menu, as an
example. Scan the Beep Tone code now. You'll hear two beeps.
3.
Then, choose the option you want to change, from the list next to the topic
bar code you just scanned. For Beep Tone, the options range from 0 for
the lowest pitch to 4 for the highest pitch. Using the "Barpad Table" on
the right side of the Reader Setup Menu, scan the number or letter
associated with the option you have selected. Let's change the beep pitch
to Highest.
4.
Now scan End Setup (at the top-right corner of the Reader Setup Menu to
complete the setup exercise. You'll hear three beeps,. If you followed the
instructions correctly and successfully changed beep tone to "highest", the
10
three beeps will be higher in pitch than the other beeps had been. If they
aren't higher in pitch, repeat the steps on this page until you are successful at
changing the beep tone.
Now that your beep tone is at the "highest" pitch, you may want to change it
back to "medium" or a different setting. Repeat the steps above, selecting the
option you prefer to "highest" in step 3.
When you've successfully changed the beep pitch, and are ready to configure
the reader for your specific application, scan Start Setup again. Continue
scanning topics and options until you've made all the changes you desire, and
then scan End Setup to complete setup. For keyboard models, pay attention to
Keyboard Country, Computer Interface, and Data Transmission Timing. For
serial models, pay attention to Baud Rate, Parity, and Data Bits. 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 Wireless Reader
options. Default settings are shown in bold in this manual and marked with an
* on the Reader Setup Menu.

Default Channel
•
The default Channel is always shipped as 0. There are 10 channels
in the USA and Canada. The Channel can be set by scanning the bar
coded 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.

For information about Code 39 and Full ASCII Code 39, see Appendix C.
See page 28 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.
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.

EAN-8 is forced to transmit 8 digits
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 C0de 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.
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.
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
transmission 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.
15
2 of 5 Data Length
2 of 5 Code is so susceptible to interpreting partial scans as valid reads
that the Radio/Freedom Reader 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!

For more information on Code 93 see Appendix D.
Terminator characters
Enter (carriage return)
None
HT
CR/LF
Depending on your application, you may wish your Wireless Reader 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 HT or CR/LF, you can
get it by specifying None here and then selecting your desired terminator
character(s) specified in the Postamble (See Page 18).
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. With the 2Way LZ2x2-RF Laser, the Preamble applies to the scanner, not the base
station because there may be multiple scanners per base.
The default is no preamble. To select a preamble, 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 preamble setting, scan Clear here
instead of scanning SET or any characters from the FULL ASCII MENU.
16
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
XYZ
~3XYZ
~9
~A
~5
Data Transmitted
XYZ123
XYZ45678
12345678
12345
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 13 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:

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. (Don't use this option to configure the Radio/Freedom Reader
for your non-US keyboard -- instead, use the Keyboard Country option
described below.)
For example: Suppose you want the Radio/Freedom Reader 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
back of Wireless Setup 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.
Keyboard country
This option configures the Radio/Freedom Reader for your choice of 15
keyboard country settings, such as USA (the default), UK, French, German, etc.
Scan the keyboard country bar code and then the two-digit code for your
keyboard country (listed on the Reader Setup Menu), such as 14 for UK.
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.
18
Link Test Code
This is a code to test the transmission link between the Wireless Scanner 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 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 Wireless Reader to its default settings (as described on page 9),
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 Protocol
Scan 3 to select a 1 second aiming dot, or
4 to select a 2 second aiming dot, or
5 to select a 3 second aiming dot, or
6 to select a 4 second aiming dot, or
7 to select a 5 second aiming dot, or
2, the default, to eliminate an 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. (CCDs will not read through a windshield,
only laser scanners.) You may want to use the aiming dot above too.
19
"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”:
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.

This applies to use of the "F45-1 Serial Y Cable" only. "Full Duplex" means
that the R/F Reader will transmit data only through the HOST connector. With
"Half Duplex", data is transmitted through the HOST and TERM connectors.
Full Duplex should be used in almost all cases, but Half Duplex. 0 is useful for
testing pin-out reversal.
21
Protocol
This parameter only applies to serial operation of a Base Station.
None
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.)
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.
Please refer to Host Response Delay to determine if you need to compensate
for slow host program response by slowing down the retry time when failing
to get a response from the base station.
22
Test the Reader with your computer
If you are connected by usb interface, or if you have a serial reader and are
using PortKey with an IBM compatible, you should be able to scan the bar
code on the next page, hear a beep (2 beeps on 2-way laser), 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
10. 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 (two
beeps with 2-way laser scanner), but no data displayed:
If you still have trouble, see the Troubleshooting section of this manual.
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 on the enclosed 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.
24
Accumulate Mode
Accumulate Mode is an option (which can be enabled or disabled using the
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.
Clear Buffer

Enter
Function/Control Key Support
The RF Scanner 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.

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.
26
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:
Keystroke
Alt ON
Ins (0 on the numeric pad)
Down Arrow (2 on the numeric pad)
Numpad 5
Ins (0 on the numeric pad
Alt OFF

• All of the above problems are an indication that your BATTERIES ARE
TOO LOW. With any of the above symptoms, recharge the battery in the
RF Laser before assuming you have some other kind of problem.
The reader won't beep when reading bar codes
• Recheck all the connections. Get close to the Base Station. Try reading
the Link Test bar code, following the steps for scanning on page 10.
•
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 25) will not be transmitted to your
computer until you read a bar code without a leading space. Try
reading the Test Label on page 23 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.
•
Reread the configuration section and make sure you properly enabled
the bar code types you're trying to read.
Extra characters at the beginning or end of your bar code data
• Clear the Preamble and Postamble.
Poor read rate
• Get close to the Base Station and try reading the test label on page 24
(following the scanning instructions on page 9) as an example of a
known good bar code. Examine your bar codes to make sure they have
dark bars, clearly defined bars and white spaces, and a "quiet zone" of
at least 1/4 inch to the left and right. If the bars are gray, or so dark that
they "bleed" into the white spaces, the person or organization printing
them will need to adjust the printer or get a new ribbon or toner
cartridge for it.
I get six beeps when the RF Laser powers up or six flashes or the Base
Station flashes and turns Red or Orange.

Serial Troubleshooting
The reader beeps on reads, but nothing appears on your screen using
PortKey OR nothing appears to your own software.
• Recheck the installation instructions beginning on page 2 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 25) 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 23 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.
•
Try reading a known good bar code -- the test label on page 23,
following the steps for proper scanning technique on page 9.
•
Read the instructions beginning on page 9 on configuring the Reader
for different bar code types and formats, and make sure you properly
enabled the bar code types you're trying to read.

Data characters are garbled or missing.
• Make sure you've set the reader to the same baud rate, parity, data bits
and stop bits as your serial port.

If you're getting occasional extraneous characters, try cutting the
jumper between pins 8/20 in the serial Y-Cable's DB25 connectors. See
page 7.

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 screw driver 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.
32
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.
33
Appendix B
Recharging the Batteries
The LZ400-RF Laser and LZ403-RF Laser have 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, (DON'T USE ANY Supply Except Worth
Data). That way it will always be recharged. The built-in recharger is a smart
charger, so you can't overcharge the battery and ruin it.

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 -.
*C39*
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 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 Wireless Readers give you
the option of transmitting or not transmitting these characters when the bar
code is read.
Exact specifications for Code 39 and other bar code symbologies can be
obtained from ANSI at the address below:

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
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.
36
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.

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.
, and
. Full ASCII 93 is created by
The control characters are
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.

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.
a12345b
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.
Codabar start/stop transmission
The Codabar section on the Wireless 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 Wireless Reader and data coming from the
keyboard. If neither situation applies, you'll probably want to disable it.
39
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
12345
encoding scheme to create a more compact bar code.
Code 128 uses an internal Mod 103 check character that
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 Wireless 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).
40
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
Wireless 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 Wireless Reader to look for one length of I 2 of 5
code only. By default, the Wireless 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 Wireless 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
42
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
43
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. UPCE 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:

8:00 a.m. to 6 p.m. EST
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 UPC Council. 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.
44
•
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 UPC Council. (Do not use 0 as the leading number
for in-store marking).
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 Wireless Reader 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 Wireless 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:
1.
odd
even
odd
even
odd
even
odd
even
odd
even
odd
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.
5.
99 + 26 = 125
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).
46
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:
UPC-E Data
Insertion Digits
Insertion

Abcd00000e
Abcde00005
Abcde00006
Abcde00007
Abcde00008
Abcde00009
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:
4.
The complete 8 digit code consists of the Number System Character,
the original 6 digit code and the check digit:
01234565

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
7.
Data with check digit is:
823450
48
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
(If the remainder is 10, no check digit is added.)
6.
Data with check digit is:
9434578
