Installation
Components
The 802 Terminal is 802.11b compatible operating between 2.412GHz and 2.462Ghz
using direct sequence spread spectrum; it works with Access Points that are 802.11b
or 802.11g compatible (b is a subset of g). The components in your 802 Terminal
system will vary according to the configuration of your system. Your R/F Terminal
shipment should contain at least:
•
An R/F Terminal T802 or LT802 (unit includes keypad and display).
If the R/F Terminal is an LT802 model, it will have an integrated laser
scanner built-in to the body of the terminal. Each terminal is shipped
with a shoulder strap, boot, and Setup Menu.
•
An optional Scanner – if you ordered the T802 models instead of the
LT802 models with the built-in laser scanner.
•
Optional rechargeable batteries and a 9v power supply.
•
Utilities CD ROM – demo programs, DLL, and firmware loader program
Keep the shipping box for the R/F Terminal in the event it is necessary to
return equipment for repair later.
Installation Sequence
1.
Start with one Terminal. Get everything working with the single
terminal and base and then add other terminals, being certain that all
terminals have unique Device Addresss.
2.
Now run the T802 Test Programs to validate that everything is
working. If you have problems, refer to the Trouble Shooting Section.
Using the RF Terminal keypad…
The R/F Terminal is turned on by pressing the green
ON/OFF button located in the upper left-hand corner
of the R/F Terminal keypad.
The R/F Terminal has a Shut Down Time feature that allows you to
determine the length of time the R/F Terminal must be inactive before
automatically shutting down to conserve battery power. When the R/F
Terminal shuts down, simply press the ON/OFF button to resume operation.
The keypad is custom designed for the R/F Terminal operations. It has
numeric and control keys in the non-shifted state, and alpha characters in its
shifted state. You can readily determine if the SHIFT is on by the cursor on
1-1
the display. When SHIFT is on, the cursor is a large black rectangle. When
SHIFT is off, the cursor is a narrow underline character. For all prompts
which ask for a YES or NO response, the ENTER key, is the YES reply,
and the 0 (zero) key is the NO reply. As you key data, you will see each
character displayed on the screen. If you make a mistake, you can delete the
last character by pressing the DELETE key, or you can clear all characters
displayed on the screen by pressing the CLEAR key.
You can order NIMH batteries (L01) from Worth Data along with a 9v
recharging Power Supply that recharges the batteries completely within 2
hours. When recharging options are ordered with the Terminals, the
Terminal's Batteries Setup parameter is set for recharging "1" which allows
the batteries to be recharged under program control. Otherwise, the batteries
shipped are alkalines with no recharging options set in the Terminal.
However these are changeable by the customer. Using NIMH or alkaline
batteries, you should get 24 hours of operation (assuming 1 transaction
every 8 seconds).
If you did not order the rechargeable batteries and you change to
rechargeables, you must change the Terminal's Setup to Batteries 1 to allow
recharging. If you want to charge the batteries without having to remove
them from the Terminal, you must use the Worth Data 9v power supply.
You can safely use alkaline batteries in a terminal set for recharging,
providing you don’t plug a power supply into the terminal. Recharging
Alkaline batteries may cause the batteries to explode and leak battery acid
throughout the RF Terminal. Battery acid damage is not covered by the
Worth Data warranty because it not deemed to be “normal use”.
If you are using alkaline batteries (either regular or rechargeables) and
have selected the Rechargeables setting in the Battery setup parameter (See
Chapter 2; RF System Setup), the RF Terminal will generate the following
error message:
Alkaline Batteries
Detected,
Rechargeables Are Specified
Do Not Recharge
Battery Life Indicator
The R/F Terminal detects low AA batteries and displays the following message:
LOW BATTERIES
Finish, Sign Off
Change Batteries
Hit Any Key_
At this point you have approximately 2 minutes of operational time to finish
your transaction (or note where you are leaving off if in the middle of a
1-2
transaction) and sign off. After 2 minutes, the R/F Terminal displays:
CHANGE BATTERIES
UNIT SHUT DOWN_
This message displays for 20 seconds before the R/F Terminal signs off from
the host (if signed on) and then shuts itself down. If you turn it back on
without changing batteries, you may experience constant beeping, intermittent
scanning, and very irritating symptoms that look like equipment failure.
Once you remove the batteries, you have 5 minutes to change them before
you lose the date and time in the Real-Time Clock.
The R/F Terminal also has a battery life indicator . To display the
remaining battery life of the AA batteries (as well as the date and time)
press the STATUS key:
mm/dd/yy hh:mm
AAxBAT










-zz%
x=a when Alkaline batteries are specified in Battery setup
x=n when NiMH or NiCad batteries specified in Battery setup
zz=percent in numbers i.e. 99, 10, 05
Press the STATUS key again to resume processing.
To change the AA batteries:
1.
2.
3.
4.
5.
6.
Turn OFF the R/F Terminal.
Remove the battery holder door on the back of the R/F Terminal by
pressing down on the grooved portion of the door and pushing outward.
Remove the old batteries and insert the new ones, making sure to
orient the batteries with the positive (+) end facing down toward
the bottom of the R/F Terminal.
If using rechargeable batteries, make sure that rechargeables are
specified. See the previous page to quickly determine the setting
using the Status key.
Replace the battery door and turn the reader on using the ON/OFF
switch.
Sign ON and resume your application.
Recharging the batteries
1.
2.
3.
Be sure you have specified rechargeable batteries in the RF
Terminal's Setup. If you ordered rechargeable batteries with a RF
Terminal, Worth Data makes the change before shipping. See
Battery in the RF Setup.
With the RF Terminal shut off, plug the 9V power adapter into the
RF Terminal.
The firmware in the terminal then checks the level of charge in the
1-3

batteries to see if they need charging, displaying the following message:
Checking Batteries
Please Wait………..
If the batteries are already charged, the message will disappear. If
the batteries need charging, the following message is displayed:
Charging Batteries
Please Wait………..
R/F Terminal Menu Functions
There are four modes of operation for the R/F Terminal:
SIGN ON
Signs R/F Terminal on for two-way communication
with host.
SETUP MODE
Accesses Setup parameters for Terminal and Base.
Upon power-up, the R/F Terminal displays the following opening screen:
802 TERMINAL 3C1nnnx
ServerIP=nnn.nnn.nnn.nnn
DeviceIP=nnn.nnn.nnn.nnn
Ch:=n SSID=xxxxxxxxxxxx
WEP=Y Strength=-nn
HIT ANY KEY
(The opening screen can be bypassed upon power up. See Chapter 2)
•
The first line on the screen, 802 TERMINAL 3C1nnnx, gives the
firmware revision number.
•
Server IP either shows the Server's fixed TCPIP address; or if
Device searches out the Server, shows 0.0.0.0.
•
Device IP either shows the Device's fixed TCPIP address or that
it is determined by a DHCP Server shows 0.0.0.0.
•
Ch:=n shows the channel to start using, (the channel of the most
frequently used Access Point).
•
•
SSID=xxxxxxxxxxxx refers to the 12 character network name.
WEP=Y (or N) shows that the Device is configured with an
encryption key.
•
Strength=-nn shows the signal strength from the best Access

*All parameters are set back to their defaults when reset using the bar coded Setup Menu, even
parameters that are changed by keypad only. Shaded items are keypad access only.
Using the bar code RF Terminal Setup Menu
To use the bar coded RF Terminal Setup Menu, scan these bar codes in this
order:
•
•
Start Setup - you should hear 2 beeps
Setup Parameter bar code (i.e. “Beep Tone”)-you should hear 2
beeps for each scan
2-2
•
Number bar code that corresponds to the appropriate setting
(i.e. “3” to change the Beep Tone to “high”) - you should hear 2
beeps for each scan
•
End Setup-you should hear 3 beeps after END SETUP.
More than one Setup Parameter can be changed before you scan END
SETUP. For example, if you scanned START SETUP, then “Beep Tone”,
then 3, then “Speaker Operation”, then 1, then END SETUP, this would
change the beep tone to “high”, and turn the speaker "off".
If you are using a Laser Scanner to setup the RF Terminal, the beam will
often cover more than one bar code. Cover any adjacent bar codes before
scanning, and then check the RF Terminal display to make sure the correct
setting was entered.
Using the keypad to setup the RF Terminal
The RF Terminal can be setup via the Terminals' keypad by entering Setup
Mode from the menu. Turn on the Terminal and press any key. You should see:

RF Terminal Setup Parameters
Default settings are shown in bold type in this manual and are marked by a * on
the bar code Setup Menu.
The RF Terminal will typically require no setup changes except, Device Address (if
more than one terminal) and enabling bar codes to be read other than UPC or Code 39.
Device IP Address
Get Device IP from DCHP Server
Use a Fixed Address
•
0.0.0.0
nnn.nnn.nnn.nnn
Every terminal needs a unique Device IP Address. You can use a fixed
IP address, or you can use a DHCP Server to obtain an IP address.
Enter in the address in the format of nnn.nnn.nnn.nnn (where each n is
a value of 0-9); or if you wish to use a DHCP Server, enter 0.0.0.0. The
terminal's default setting is to use a DHCP Server.
Server IP Adress
Search for Server IP Address
Use a Fixed Address
•
0.0.0.0
nnn.nnn.nnn.nnn
The terminal communicates with a Server by IP address. The Server IP
address can be found by a search initiated by the terminal, or you can
enter in a fixed IP address for the server. The default setting in the
terminal is to search, (a setting of 0.0.0.0). If you want to use a fixed
server IP address, enter the IP address nnn.nnn.nnn.nnn (where each n
is a value of 0-9.

characters can be useful if you need to differentiate between data that
comes from a bar code versus data coming from the keypad.
•
Enabling use of the Mod 43 check character requires that the last
character of your bar code conform to the Mod 43 check character
specifications. See Appendix E; Code 39 for more information. Enable
transmission (A) will send the check digit data along with the rest of the
bar code data to your computer. To use A, you must also be using 8.

Terminal can transmit it in the ISBN format. The settings for this are
found under the Laser Options parameter. To enable transmission of
the ISBN format, set the Laser Options parameter to D. To return to
the default of normal EAN-13 transmission, set it to C. For details on
ISBN, see Appendix J, UPC/EAN.

2 of 5 is so susceptible to misreads that the RF Terminal adds an additional
safeguard - it can be configured to look for fixed-length data only.
•
The default setting of 06 causes the RF Terminal to read only 2 of 5
codes that are 6 digits in length. To set the RF Terminal to read a
different length, scan any two-digit number from the bar pad table. For
example, to change the RF Terminal to accept an 8-digit bar code, scan
0 then 8 from the bar pad table. 2 of 5 code must always be an even
number of digits so the length setting must always be an even number.
•
Reading variable length I 2of5 or 2 of 5 codes is to be avoided if at all

Preamble
Preambles are user-defined data that is attached to the beginning of data
(bar code or keyed) that is transmitted to the host by the RF Terminal. For
example, if you set a preamble of @@ and scanned bar code data of 12345,
@@12345 would be transmitted to the host.
•
By default, the RF Terminal has no preambles configured. Preambles
can contain up to 15 characters scanned from the bar coded FULL
ASCII Menu. To set a preamble:
1.
2.
3.
4.
•
Scan the Preamble bar code or select Preamble from the
keypad menu.
Scan the desired characters (up to 15) from the FULL ASCII Menu.
Scan the SET bar code, or if using the keypad, press ENTER.
To clear the Preamble and return to the default (no Preambles
defined), scan CLEAR at step #2, and then continue with your
setup.
You can use the Preamble to trim characters from the data you are
entering into the RF Terminal. You can trim from 1-15 characters from
the data by creating a preamble of:
~x
where ~ is ASCII 126 and x is a single hex digit 1-F (corresponding to
1-15). Data that is shorter than the trim amount is transmitted without
trimming. Preambles trim characters from the front of the data. Here
are some examples:

Using the Bar Code ID feature and the Preamble, you can trim data
selectively, trimming characters only on the bar code type specified.
To use selective trimming, enter:
~bx
where b is the Bar Code ID character (see the Code 128 setup parameter)
and x is the number of characters to trim from the front of the data. For
example, ~b2~c1 says “trim 2 characters from Code 39 data and 1
character from UPC-A data”. Remember that the Preamble trims leading
data. This applies to One-Way and host prompted communication.
•
Lastly, the Preamble can be used to check a minimum/maximum data
length for bar code data entered. To check for bar code length in the
Preamble enter:
|nnmm
where | is ASCII 124, nn is the two-digit minimum and mm is the two-digit
maximum. |0210 would check for a minimum of 2 characters and a
maximum of 10. If you try to scan a bar code outside the minimum or
maximum lengths, no decode will result. Entering data by keypad is not
affected.
Other
Postamble
Postambles are user-defined data that is attached to the end of data (bar
code or keyed) that is transmitted to the host by the RF Terminal. For
example, if you set a Postamble of @@ and scanned bar code data of
12345, 12345@@ would be transmitted to the host.
•
By default, the RF Terminal has no Postambles configured. Postambles
can contain up to 15 characters scanned from the bar coded FULL
ASCII Menu. To set a Postamble:
1.
2.
3.
4.
Scan the Postamble bar code or select Postamble from the
keypad menu.
Scan the desired characters (up to 15) from the FULL ASCII Menu.
Scan the SET bar code, or if using the keypad, press ENTER.
To clear the Postamble and return to the default (no
Postambles defined), scan CLEAR at step #2, and then
continue with your setup.
2-15
•
You can use the Postamble to trim characters from the data you are
entering into the RF Terminal. You can trim from 1-15 characters from
the data by creating a Postamble of:
~x
where ~ is ASCII 126 and x is a single hex digit 1-F (corresponding to
1-15). Data that is shorter than the trim amount is transmitted without
trimming.
Postambles trim characters from the end of the data. Here are some
examples:

To use selective trimming, enter:
~bx
where b is the Bar Code ID character (see the Code 128 setup
parameter) and x is the number of characters to trim from the end of
the data. For example, ~b2~c1 says “trim 2 characters from Code 39
data and 1 character from UPC-A data”. Remember that the Postamble
trims trailing data.
•
Lastly, the Postamble can be used to check a maximum character
length for data entered. To check for length in the Postamble, enter:
|nnmm
where | is ASCII 124, nn is the two-digit minimum and mm is the twodigit maximum. |0210 would check for a minimum of 2 characters and
a maximum of 10 If you try to scan a bar code outside the minimum or
maximum lengths, no decode will result. Entering data by keypad is not
affected.
Characters
This setting allows the RF Terminal to output chosen ASCII characters in
place of the actual characters entered. For example, if you scanned the
number 1 (hex 31) and wanted the RF Terminal to output hex 92 instead,
you would enter 3192 for the Characters parameter. This would re-assign
the output characters, with the RF Terminal outputting hex 92 every time it
sees hex 31. To re-assign characters:

xx is number of ½ second messages
yy is the number of 1-second messages
zz is the number of 2-second messages
The total time allotted must not exceed 75 seconds. To change the partitions, scan
or enter 6 digits total; 2 for the number of ½-second messages, 2 for the number
of 1-second messages and 2 for the number of 2-second messages. See the
default setting as an example.
WARNING: changing the Voice Message Partitions parameter after you
have recorded messages could result in having to re-record some of them;
they would still be there but longer messages may get cut up and shorter

Shut Down Time
Other
By default, if the RF Terminal is inactive (no keystrokes or scanning) for
more than 5 minutes, it will shut itself down in order to conserve batteries.
This includes SIGNING OFF if appropriate. To resume operation, you
must turn the RF Terminal back on using the ON/OFF key. To change the
amount of time the RF Terminal waits before shutting down:
•
•
Scan Shut Down Time
Scan two digits - the default is 05 (5 minutes)- to correspond to the
length of time in minutes. For example, 01 would be 1 minute.
If you want to prevent the RF Terminal from shutting off automatically at

the features below seem to fit your situation, set them appropriately.
Settings C through F are not laser-dependent and are for UPC/EAN bar
code types only. See the UPC/EAN parameter for more information
•
Double Decode is there to minimize the possibility of misreads when
scanning very poor quality bar codes. This option forces the RF Terminal
to keep reading until it gets two results that are identical. This "double scan
checking" takes longer but will minimize misreads since it must get the
same result twice before considering it a "good" read.
•
4-second laser beam increases the amount of time the laser beam is
activated, giving the laser more time to try and read a code. This
option is useful for trying to read poor quality code. Using the 4second laser beam with long range lasers give the operator more time to
aim the laser properly at a distant bar code (usually using the "marker"
beam). The default beam time is 2 seconds.

Aiming Dot Duration
This parameter applies to the built-in internal laser and the LZ200 and LZ400

Chapter 3
Operational Theory
Before you jump in and start writing a complex host program, it might be nice to
be familiar with the theory behind the operation of your RF Terminal.
Basic RF System communications…
A WIFI system consists of three components – Host Server, Access Points
and RF Terminal. The Access Points are connected to the Server by
Ethernet wiring. The Terminal Device "signs in" by establishing
communication with a Server Program through an Access Point. After the
terminal "signs in" the host program can send a prompt to the terminal with
the ActiveX program interface provided by Worth Data. The application
running on the Server sends a data prompt to the terminal device using the
Ethernet wiring to the Access Point and then by radio link to the terminal
device. The RF Terminal displays the data prompt on the display and waits
for the operator to enter the requested data. Once the operator enters his
data, the RF Terminal transmits the data to the Access Point, which in turn
passes it on to the Server. The application on the host computer processes
the information and sends a new data prompt out to the Access Point and
the whole process begins again.
A little more in depth…
This RF system’s dialogue is Terminal initiated. The Terminal says, “I’m
here, give me something to do.
When you select DEVICE SIGN ON?, the RF Terminal first establishes
communication with the network as follows:
1.
It looks for an Access Point with an identical SSID using the Channel
Number in its configuration as the starting channel.
2.
Once it finds an access point, it checks to see if the encryption of the
Access Point matches its WEP key.
3.
If the unit is configured to obtain its IP address from a DHCP Server, it
requests an IP address from a DHCP Server.
4.
If it does not have a fixed Server IP address configured, it does a search
for an application Server.
5.
Now the Terminal Device sends a SIGN ON message to the application
Server. All messages include data as well as the transmitter's and
receiver's MAC address, IP address, and Port address.
While attempting to establish communication with the application Server,
the Terminal Device will display the following message:
WAITING ON SERVER TO ACKNOWLEDGE
3-1
When the Server receives a SIGN ON message from a RF Terminal, the
Server transmits the SIGN ON information to the host application program..
The host application can then do one of two things:
1.
2.
If it has something for the Terminal to do, it can send a prompt to the
Terminal. The RF Terminal receives the prompt, waits for the
operator to enter the requested data, and then transmits the data back
to the application program.
If the host program does nothing within an allotted time, the
Terminal displays the message:
WAITING ON HOST PROMPT
Lets suppose that a RF Terminal and a host application program have been
processing data by sending prompts and data back and forth as described in
example 1. The host application program sends a data prompt to the RF
Terminal. The RF Terminal transmits the operator-entered data back to the
Server. If the host application program has another prompt for the
terminal, it sends it out, repeating the process above.
If the host application program doesn't respond immediately, the Terminal
Device displays:
WAITING FOR HOST PROMPT
until the prompt is received.
If the Terminal gets no response after several re-transmissions, it assumes it
is out of range from the Access Point with which it was communicating,
and attempts of establish contact with any Access Point. If the Terminal
can't establish communication with an Access Point, it displays:
TRANSMISSION FAILED
HIT ANY KEY_
Pressing a key on the Terminal starts the re-transmission process over
again. The RF Terminal will try to retransmit its data, displaying the
TRANSMISSION FAILED message after several unsuccessful tries.
Can I change a prompt after it has been sent?
Normally once the Terminal has received a prompt from the host, it goes to
sleep and waits (as long as it takes) for the operator to scan or key
something in response. The host cannot send another data entry prompt
without creating a "Sequence Error." However, you might want to change
the prompt or locate a lost terminal with beeping. You can send an advisory
message as long as it doesn't end with a request for data entry. For example,
maybe you want to send a message "See Supervisor" or 20 beeps to be sure
the unit has not been misplaced and to aid in finding it. It is the user
programmer's responsibility to no overwrite the last data entry prompt, (the
advisory message should go onto the display in lines that are different from
the last data entry prompt.

Performance Issues
Evaluating your area of planned operation
Since every operational environment is different, it is impossible for us to
tell you exactly what equipment you need and where you should put it to
achieve maximum performance from your RF System. However, since the
Access Points are very inexpensive, you should be able to obtain whatever
coverage you need. You can evaluate the RF Signal Strength of the
strongest Access Point with the same SSID by simply pressing the Status
Key. The status key will display the following:
mm/dd/yy hh:mm
alkBAT










-zz%
ServerIP=nnn.nnn.nnn.nnn
DeviceIP=nnn.nnn.nnn.nnn
Ch:=n SSID=xxxxxxxxxxxx
WEP=Y Strength=nnn
The last line shows the signal strength. This is a number that can vary from 0100, 100 being best. You have adequate signal strength at 20. If you have less
than 20, you need to add an Access Point.
There is also some basic information about Radio Frequency itself that can help you
make smart choices about the location and composition of your system:
•
Metal walls are almost impenetrable by RF. If your warehouse
computer is located in a metal shed, don’t locate the Access Point
Station inside with the computer. Locate at least one Access Point
outside the metal shed instead.
•
The more walls you try to transmit through, the more the signal
breaks down. Walls that have metal studs (interior office walls)
and concrete walls with steel rebar slightly degrade the signal with
each wall you try to go through. Metal walls may require the use of
Relay Stations to achieve adequate coverage.
•
Organic material absorbs RF energy. If you are trying to operate in
an area with lots of densely packed organic material (bags of beans or
corn), expect and plan for reduced operating ranges.
Raise the Access Point. Sometimes just raising the Access Point 12 feet will
dramatically increase your operating range, especially in a warehouse or grocery
store environment. Mounting the Access Point on the ceiling with the antenna
pointing down is the best.
4-3
Chapter 5
Before you begin programming…
The RF Terminal receives messages from the host user program. The Terminal
responds back to the host application program with data that was keyed or scanned
by the Terminal's user. The host application program processes the data and sends
back the next prompt. Each RF Terminal has a unique IP address (or at least a
unique Mac address). The Server program either reports the IP address or for the
sake of compatibility with programs written for 70/700 series terminals, resolves
terminal addresses to a single character Terminal ID (0-9,A-Z, a-z, and -=).
This dialog is established when a Terminal SIGNS ON to the RF network. The
host computer application waits until a Terminal SIGNS ON, then begins its
processing by sending the first prompt out to the Terminal via the Access Point.
Before you begin programming, there are some factors you should take into
consideration during the planning process.
•
Plan for system failures. This includes hardware failures,
software failures and operator failures. In order to create an
efficient application, you must put some thought into what you will
do when different parts of the system fail.
•
Look for All Errors. Be sure your program is trapping all possible
error conditions that the Server may return to you. The list includes:
Sequence Errors detected
Illegal Command detected
Server Re-Initialized
Addressing a Terminal Not Signed In
Command without an ID
All of these error conditions are detailed in the next chapter. Don’t
forget to program for them; this is a common mistake. Failure to
trap them will give create very strange, unpredictable results.
Even though you don’t think your code will ever make a mistake,
take advantage of feedback that the Server provides. Failure to do
so is a common mistake that eventually results in serious program
failure, sometimes due to hardware problems that go undetected.
•
Parse the Returned Strings thoroughly. Don’t assume anything
about the next response from the Server to your program and look
only for the partial string such as the ID only. Parse the string
returned completely, and be sure you are examining every
possibility. Failure to do so is a common mistake.
•
Plan for expansion. You may start small (1 Terminal) but try to
create an application that will allow for easy expansion.
5-1
•
Use the Test Program. The test program can at least allow you to
see how the system functions and whether you can anticipate any
system-wide problems. The test program should also be used as a
response-time benchmark.
•
Study the Demo Programs. Demo programs are included for
examples of how to use the ActiveX tool provided.
Failure Planning
Hardware Failures
Let’s assume that each part of the system has failed. How are you going to
know what has happened and how are you going to recover?
•
The most frequent failures are at the Terminal level. If a Terminal has
a hardware failure, it will not be able to SIGN OUT. It is possible for
the Terminal operator to press the ON/OFF key or the F1 key by
accident, forcing the Terminal to SIGN OUT - sometimes in the
middle of a transaction. This happens at battery-changing time also.
You need to plan for partial transactions - do you trash the data you do
have and start over, or pick up where you left off?
•
Keep in mind that if a Terminal has SIGNED OUT in midtransaction, the Server clears any pending message for that
Terminal before it will allow it to SIGN ON again. Make
allowances to re-send messages or prompts that were cleared upon
SIGN ON if necessary.
Operator Errors
• Plan on your operator walking out of range and going to lunch in
the middle of a transaction. What do you do with the data you do
have, and where are you going to start up again?
•
Let’s say your operator is SIGNED ON and decides it’s time to
take a break. Instead of pressing the F1 key to SIGN OUT, he
presses the OFF key. Pressing the OFF key is OK (it will SIGN
him OUT) but there is a delay until the SIGN OUT is
acknowledged. Because of the delay, the operator might think he
didn’t press the key hard enough and press it again - this time
actually powering down the Terminal before the SIGN OUT was
complete. If this happens, you need to plan to re-send the last
prompt to the Terminal when he SIGNs ON again.
5-2
Chapter 6
Programming for the RF Terminal
The programming support offered for the RF Terminal are Active X drop-in
components. Every necessary function is defined. You just complete the code
for each function.
Remember, plan for every error that the Server might return including:
Sequence Errors detected
Illegal Command detected
Addressing a Terminal Not Signed In
Command without an ID
Programs languages that can interface with the Active X tool include VB,
C++, Delphi, Access, FoxPro, etc.
If the Application Server receives any of
1. 5 Addressing a Terminal not SIGNed On messages in a row or
2. 5 Sequence Errors in a row, or
3. 5 illegal commands in a row,
the Server transmits the following message to the Terminal and shuts down:
Server Shut Down
Due to Host Logic
Error
Check your program to correct these errors before starting again. The host
application program will have to restart and you will have to cycle power on the
Terminal and Sign On again in order to continue.
Control Keys for Possible Programming
There are some keys on the RF Terminal keypad that when pressed, can
transmit special ASCII characters back to the host program. This feature might
be used by a programmer to allow the operator to review transactions. You can
use these keys for special program functions, such as scrolling thru data,
backing up steps, jumping, finishing a process, etc The keys are as follows:
Key
Code transmitted to Host
UP ARROW key
DOWN ARROW key
LEFT ARROW key
RIGHT ARROW key
BEGIN key
END key
SEARCH key
FS (ASCII 28)
GS (ASCII 29)
RS (ASCII 30)
US (ASCII 31)
ETB (ASCII 23)
CAN (ASCII 24)
VT (ASCII 11)
6-1
The STATUS key is reserved to only display the Time and Date.
The Control keys can be used without pressing the ENTER key by using the
Control Keys Only Terminal Setup parameter. See Chapter 2; RF System
Setup for details.
802Control/ActiveX
PromptNET/ActiveX is a drop in COM component that allows
programmers to easily add the ability to send prompts to and receive data
from their R/F Terminal across a TCP/IP network connection.
The ActiveX component is compatible with Visual Basic, Visual C++,
Delphi, and most other 32-bit development platforms. The client program
requires Windows 98 or later. See the help file for installation instructions.
Programming Considerations
Network Setup
• The network settings on the and server must support TCP/IP
communications.
•
It is critical that the Access Point(s) and Server are "visible" to
each other across your network. Both must have an IP address in
the same subnet. Both the Server and the Terminal Device(s) can
either have a static address or use an assigned IP address via a
DHCP server or equivalent. Refer to your Windows networking
administration utility in the Control Panel to configure computer IP
address settings.
•
PromptNET uses ports 54123 (server).
•
You can link server and client through a dial-up or DSL internet link
as long as the server has a static IP address and your router passes
the above ports.
•
If you are unsure of how to set up your IP configuration properly,
refer to your network administrator for help.
Server Communications
• Run the Server Test Utility on the server computer. Now go to the
client computer, set the IP address for the server computer and a
unique "Base Name" for the Client Utility and attempt to connect to
the Server Test Utility. If the Client Utility connects, you are
configured properly. Go to the server computer, shut down the Server
Test Utility and begin work on your PromptNET server application.
•
For Client/Server communications, the Client Utility is required to
be running on the PC that the serial Base Stations are attached to.
6-2
•
Before making any WDIPterm method calls in your application,
make sure to set the ServerOn property to "true".
Test For Good Communication
• Implement an event handler for OnTermBaseRegister that causes
a beep or displays a message when called. If communication
between the host PC and the base station is good, your event
handler will fire when your program is running and you power up
an attached base station.
Multiple Base Stations
• For installations using multiple base stations attached to a single
client PC, simply use the four "channels" provided by the Client
Utility program.
Terminal Tracking
• Since you get only one set of event handlers, you will need some
scheme for keeping track of where each terminal (up to 64 per base
station, up to 4 base stations per client) is in its transaction sequence.
One possible solution is to use a "state" variable for each terminal
(perhaps stored in an array). Test the state variable to determine the
next prompt for any given terminal. See the samples for more ideas.
•
It is very important to keep track of "login status" for each terminal.
Every SignOut event should have an associated SignIn event and a
given terminal should not be allowed to SignIn twice without and an
intervening SignOut. Multiple SignIns from one terminal without
appropriate SignOuts indicate either:
1.
2.
A terminal going out of range and having its power cycled
before returning within range OR
Two (or more) terminals using the same ID (terminal ID
conflict).
Concepts - TCP/IP COM
Drop-in components are tools that are added to your programming
environment "tool kit". Only the ActiveX variety are widely compatible
with almost all development environments. When you use drop-in
components in your program you will follow the standard object-oriented
programming paradigm that uses properties, methods, and events to
implement the functionality of the drop-in component.
Properties are the various configuration variables used by the drop-in
component. An example of a property is the ServerOn setting.
Methods are function calls used to issue commands and access features of
the drop-in component. An example of a method is sending an Input
command to the terminal.
6-3
Events are function definitions placed in your application’s source code.
The function definitions in your source code are called Event Handlers. The
skeleton structure of the event handler’s source code is automatically
generated. The code in the Event Handler is called ("fired") by the drop-in
component when a specific event occurs. An example of an event is when a
terminal returns data and the OnTermData event is fired.
The details of how to access Properties/Methods/Events varies between
development platforms. Details of how it works in some of the most popular
platforms is illustrated in the samples included with the RF Utilities CD or
available for download from our website at:
http://www.barcodehq.com/wdterminal.exe
Properties - TCP/IP COM
Properties are the various configuration variables used by the WDIPterm
control. They are directly assignable in your application (eg.
"WDIPterm.ServerOn = true") and can be set in your development
environment’s object browser.
Note that your development environment may show more properties for the
WDIPterm control than are listed here. This is normal. You may ignore properties you see listed in your development environment that are not listed here.
ServerOn
Valid values: True, False
Function:
Set to True to enable the server. Set to false to turn
the server off. You should leave this off unless your
program is actually running. Setting it to True at
design-time can cause problems.
Quiet
Valid values: True, False
Function:
If Quiet is set to True then any status and error
message generated by WDIPterm will be
suppressed.
LogFile
Valid values: blank or a valid file name
Function:
If the file does not exist it will be created. If it
exists, it will be appended to. If LogFile is blank,
no log file is maintained.
6-4
ClientList
Valid Values: Read Only.
Function:
Returns a formatted string listing all attached client
BaseNames and associated IP numbers. Format is
"basename CR/LF ip address CR/LF basename…".
Methods - TCP/IP COM
Methods are commands that you issue to the WDIPterm control. All of the
"Inputxxx" commands cause the terminal to wait for operator input.
Note that your development environment may show more available methods
for the WDIPterm control than are listed here. This is normal. You may
ignore methods you see that are not listed here.

Function:
This instructs all terminals attached to client
basename on channel to re-initialize.
TestClient
Parameters:
none
Function:
This instructs the Server to "ping" all attached

Events - TCP/IP COM
WDIPterm events occur when a specific condition is met. When an event
is "fired", an event handler function in your application is called.
Though the details of exactly how it is done varies from one programming
environment to the next, the source code skeletons for the various event
handlers are automatically generated and inserted into your source code for
you. See the samples for more specific information.
Each event passes relevant information to your event handler function.
OnTermData passes the data that was keyed or scanned into the terminal.
Terminal ID is always passed as 0-63. A terminal ID value of 99 is used as
a placeholder for logging purposes.
Once you have the event handler skeletons, you can proceed to add
whatever functionality you desire to each event.
You must set the ServerOn property to true before any events can be fired.
OnTermBaseRegister
Data passed:
basename, channel
Event:
A base station on client basename has successfully
powered up on channel and communicated with the
host computer via the serial connection.
OnTermSignIn6
Data passed:
basename, channel, terminal
Event:
A six-line terminal has signed in on channel at
client basename. Terminal ID is passed in terminal.
6-8
OnTermSignIn4
Data passed:
basename, channel, terminal
Event:
A four-line terminal has signed in on channel at
client basename. Terminal ID is passed in terminal.
OnTermSignOut
Data passed:
basename, channel, terminal
Event:
A terminal has signed out on channel at client
basename. Terminal ID is passed in terminal.
OnTermData
Data passed:
basename, channel, terminal, data
Event:
A terminal on channel at client basename has sent
data in response to an Input method call.
OnTermNotSignedIn
Data passed:
basename, channel, terminal
Event:
A command has been sent to a terminal that is not
signed in.
OnTermSequenceError
Data passed:
basename, channel, terminal
Event:
The one-for-one host prompt/terminal response
protocol has been violated. The host cannot send a
second Input command until it has received a response
from the first Input command. If a base station receives
5 sequence errors in a row, a Host Logic error is
generated and the base shuts itself down.
While PromptNET/ActiveX will intercept and
prevent most logic errors, they are still possible so
you should implement this event handler!
OnTermIllegalCommand
Data passed:
basename, channel, terminal
Event:
An illegal command has been sent to a terminal.
PromptNET/ActiveX is designed to prevent illegal
commands but we may not have imagined all the
ways in which our customers will want to use it!

OnTermUpArrow
Data passed:
basename, channel, terminal
Event:
The up-arrow button has been pressed on a
terminal. You must issue another Input method call
before WDIPterm can respond to another keypress
on this terminal.
OnTermDownArrow
Data passed:
basename, channel, terminal
Event:
The down-arrow button has been pressed on a
terminal. You must issue another Input method call
before WDIPterm can respond to another keypress
on this terminal.
OnTermLeftArrow
Data passed:

Portable Printers
Cameo and QL 3 Common Information
Both of these printers are stocked by Worth Data for the convenience of our
users who need portable printing.
These printers do not require any special protocol; they do not require the
“wake-up byte” as do other printers. They do require a special cable that
can be ordered from Worth Data (part #C12); cable pin-outs are available in
Appendix C: Cable Pin-outs.
Shipped with every Cameo or QL 3 printer ordered is a CD ROM with the
Programmers Manual in PDF format and a label design program –
LabelVista. This program allows you to design the program and create
multiple format files that can be sent to the printer where they become
resident in flash. Variable fields are defined and can then be filled in by the
program when in operation.
Keep in mind the following information when using these versatile printers:
•
The printer turn on ("Wake-up") is accomplished by the RF
Terminal toggling the DSR line on the printer, so only the @S
command and the data you are sending to the printer is needed.
•
Once the RF Terminal has turned on the printer, it stays on until
the host program turns it off using the POWER OFF COMMAND
"ESC(0x1b)`p'(0x70)" described in the Printing Systems
Programming Manual, or until the automatic shut-down takes
place (2 minute default).
•
The 231 character limit applies to your command string. See your
Portable Printing Systems Programming Manual for details on
programming your printer.
Zebra Cameo Printer
The Zebra “Cameo ” Printers are portable direct thermal receipt printers,
(not label printers – the QL 3 below prints labels). Bar codes can be printed
on the receipts, but you can’t print labels.
6-11
One model of the Cameo printer is available with a magnetic stripe reader,
allowing magnetic stripe input to the RF Terminal using the @M (magstripe
input) command.
•
The Cameo printer with magstripe input is capable of reading
Track 1, Track 2 or Tracks 1&2. See your Portable Printing
Systems Programming Manual for the correct character string to
send in the @M command to turn on the magstripe reader. (see
page 6-2 for details).
•
When the Terminal sends data to the host, it sends it in the
following format:
RF Terminal ID + DATA + CR
Typically, the data is simply a string of characters, but in the
instance of data coming from the magstripe reader, there are some
additional characters you need to be aware of. The magstripe
reader sends its data in the following formats:
Track 1:
T1: DATA
Track 2:
T2: DATA
Track 1&2:
T1: DATAT2: DATA
So, when the RF Terminal transmits the data to the host, it will be
in the following format:
RF Terminal ID + T1: DATA + CR
or
RF Terminal ID + T2: DATA + CR
or
RF Terminal ID +T1: DATA + T2: DATA + CR
For further information, see your Printing Systems Programming
Manual on the CD ROM shipped with the printer.
6-12
Zebra QL 3 Printer
The QL 3 Printer is used for label printing. It doesn’t have Magstripe input.
The classic application is for printing shelf labels during shelf price
verification:
1.
The operator scans a shelf label.
2.
The Terminal transmits scanned data to the host computer.
3.
The host computer looks up the price, description, etc. and
transmits the computer price back and sends the necessary
commands to the attached QL 3 printer to prints a new shelf label
with the correct price.
4.
The terminal operator then peels off the label and applies it to the
shelf.
Each printer is shipped with a no charge roll of thermal paper that can be
used for development, including determining the exact label size that best
fits you needs and the capabilities of the printer.
We stock the 2” and 3” QL 3 printers with several label sizes immediately
available including:

Voice Message Operations
The RF Terminal’s exclusive use of voice prompts allows you to overcome
problems such as literacy, language and lighting. With proper planning, voice
prompting can enhance your RF Terminal application, making it faster and
simpler. Voice messages are recorded in the RF Terminal, and then triggered by
a prompt from the host computer.
Why Use Voice Messages and Prompts?
•
Voice messages can be in any language.
•
The operator does not have to be able to read to perform some jobs.
•
Audible instructions can be heard in poor lighting where it is
difficult to read a LCD screen. MOST IMPORTANTLY, the data
collection process is faster because the operator does not have to
continually look at the screen for instructions. This is especially
useful when you do not want or need to enter data from the
keypad. Scanning bar coded numbers from a Quantity BARPAD
can make keying unnecessary.
Voice messages and prompts are a good way to keep the operator’s
attention focused on the job at hand. Audible error messages and warnings
also help to limit mistakes and downtime.
Tips for Using Voice Prompts
Over 90 voice messages can be recorded in the RF Terminal. Here are some
tips on making your voice prompts user-friendly:
•
Short messages are preferable for prompts; most English prompts
can be stated in ½ second. Instead of saying, “Enter the Item
Number,” say “Item”. The typical RF Terminal operator does not
want to hear long messages thousands of times. Error messages are
typically longer because they are the exception and need to provide
more precise instruction to the user.
•
Record your voice prompts calmly. A frantic sounding voice can
become irritating, especially when heard repeatedly.
•
Speak clearly. Correct pronunciation will make the voice prompts
easier to follow for all users. Use common words that all users will
understand.
•
Vary the tone of your voice for different prompts. Using a
different tone of voice or even a different voice for consecutive
7-1
prompts or error messages will make it easier for the user to
distinguish between them.
•
Be sure to record error messages for all possible problems that
the user may encounter during a session. Once the operator
becomes accustomed to listening to the voice prompts, it may
become easy to overlook a “display only” error message.
RF Terminal’s Voice Message Mapping
The RF Terminal is shipped with 75 seconds of total recording time. The
time allotted for each message is partitioned as follows:
30 – ½ second messages (message numbers 01-30)
30 - 1 second messages (message numbers 31-60)
15 - 2 second messages (message numbers 61-75)
Messages are sequentially numbered beginning with the ½-second
messages, followed by the 1-second messages, and finally the 2-second
messages. You can change the partitions to allow for more or less of a
particular length message. For example, if you decide you do not want any
½ second messages and you want 15 more 1-second messages, your
allocation would look like this:
00 – ½ second message
45 - 1 second messages (message numbers 01-45)
15 - 2 second messages (message numbers 46-60)
Voice message partitions are set in the RF Terminal either from the bar coded
Setup Menu or by the keypad setup. From the Setup Menu, scan the bar code
for “Voice Messages”, and then scan six digits. The first 2 digits correspond to
the ½ second messages, the second 2 digits for the 1-second messages and the
last 2 digits for the 2-second messages. See Chapter 2; RF System Setup for
details on Terminal setup (by bar code setup menu and keypad). Remember that
the total amount of time must add up to 75 seconds.
Programming Voice Messages
To record and playback messages or assign messages to error conditions,
you have to get to SETUP MODE and enter the password. If you don’t
know how to do this, see Chapter 2; RF System Setup for details on how to
get into the SETUP MODE. Once you have entered the password (OK, its
WDTRI) you will see the following prompt:
R/F Terminal Setup->1
R/F Base Setup------>2
Voice Operations---->3
Press 3 to select Voice Operations. The next screen gives you your options:
7-2
Record/Playback--->1
Assign Errors------->2
Cloning Master----->3
Cloning Receiver-->4
Pressing the “1” key takes you into the voice recording and playback
function. Pressing the “2” key allows you to assign voice message numbers
to error conditions. “3” and “4” allow you to clone voice messages from
one RF Terminal to another. Each option is shown in detail below:
Recording and Playback of Voice Messages
If you respond with a “1” at the menu, you will see the following
Record/Playback prompt:
RECORD/PLAYBACK?
KEY [R/P]?
First, we will playback a message that has already been recorded. Let’s use
message #01 for this example. Press the P key (for Playback) to get to the
next prompt:
KEY [R/P]?
MESSAGE #: _
At this prompt, enter a two digit number for the message number you want
to listen to. Enter “01” and then press the ENTER key. You will probably
hear the “ITEM” prompt recorded at the factory unless you have edited or
reset the default messages. If you heard nothing, a new message can be
safely recorded in the area assigned to message # 01. After you have heard
the message (or static if no message has been recorded), the RF Terminal
displays the RECORD/PLAYBACK prompt again:
RECORD/PLAYBACK?
KEY [R/P]?
To record a message, get out the microphone (no, it’s not an earphone)
shipped with the RF Terminal and plug it into the AUX jack located next to
the POWER jack on the bottom of the RF Terminal. Answer the prompt by
pressing the R key to record a message. The bottom line of the display now
reads:
MESSAGE #: _
Enter the message number you are going to record. For this example, enter
message #03 (by default this is a blank message) by pressing 03, then the
ENTER key. The RF Terminal screen now shows:
HIT ANY KEY TO
START RECORDING
7-3
To record a message, press any key and hold it down. When you release the
key, immediately start speaking into the microphone. To practice, let’s
record something in message #03. Get ready to say ITEM (in English or
your language) into the microphone of the RF Terminal. When ready, press
the ENTER key and the instant you release it, speak ITEM into the
microphone. Remember to speak clearly – you have plenty of time to say
ITEM in ½ second. When the message time is over, you will hear two
beeps. The display is back to the RECORD/PLAYBACK prompt:
RECORD/PLAYBACK?
KEY [R/P]?
Now you’re ready to listen to your first recording. Press the P key and key
in 03 for the message number. Do not be discouraged if you didn’t record
the entire message. Our first attempt produced “EM” in a very frantic tone
of voice. Practice speaking clearly and calmly (think of the poor guy who
has to hear it 10,000 times next week) as soon as the key is released. You
will get the hang of it with just a little practice.
That is the way all messages – prompts and errors - are recorded. If you are
not sure which message numbers are blank, you can listen to messages until
you find a blank for recording.
The host computer relies on the fact that the voice messages are stored in
the RF Terminal itself and not generated by the host. The host computer
will trigger the broadcast of a voice message by sending a prompt to the RF
Terminal that tells it which message number to play. If the host thinks that
message #05 is STOP when it’s really GO, it can cause confusion for the
operator. That is why it is important to keep track of what messages are
recorded where.
Assigning Error Messages
Error Messages are recorded the same way other messages are - by going
into RECORD/PLAYBACK, selecting a message number and recording a
voice message. The RF Terminal comes from the factory with some voice
prompts and error messages pre-recorded. You can change any of these
messages but keep in mind that the error conditions are hardware-related
and that the voice error messages they are linked to are fixed. For example,
the “Low Batteries” message is located at message #31. Whenever the RF
Terminal detects very low batteries, it will play message #31, regardless of
what is recorded there. You could record “Happy Birthday” and the RF
Terminal would broadcast it any time it detected the low battery condition.
To avoid confusion, try to keep the error messages somewhat related to the
error condition they represent.

Cloning Voice Messages and Setup from RF Terminal
to RF Terminal
If you have several RF Terminals, you can record all of your voice
messages in one RF Terminal and then simply “clone” them to your other
RF Terminals. Cloning also copies the RF Terminal setup (except for
Terminal ID).
You need 2 cables to clone RF Terminals; the Data Cloning Cable #F38
and the Voice Cloning Cable #T15. The Data Cloning Cable plugs into the
“Computer” port on each RF Terminal. This cable must be connected to
clone properly.
One jack on the Voice Cloning Cable has two black rings on it – this end
must plug in to the RECEIVING RF Terminal (the one you are
transmitting to). Plug the single-banded jack end into the MASTER RF
Terminal (the one you are going to record from).
Once both cables are plugged in to both Terminals, go to the Setup Menu on
both Terminals. Select 3 for Voice Operations from the menu.
The “Receiving” RF Terminal must be started first. On the receiving Terminal,
press the 4 key for Cloning Receiver. The “Receiving” unit will display:
Recv Setup/Voice
Please Wait_
Now you can start the “Master” RF Terminal by pressing the 3 key for
Cloning Master. The “Master” Terminal will display:
Xmit Setup/Voice
Please Wait_
During the cloning process, you will hear the voice messages played aloud
as they are copied. The process takes about 75 seconds to complete. After
the Terminals are done cloning, they will both display:
End of Cloning
Hit Any Key_

If you did not hear the correct messages or you heard no messages at all,
check your cables and receiver/master setup - you may have transmitted
from the wrong RF Terminal.

If you get the DATA XMIT ERROR message, you have to restart the whole
cloning procedure.

Troubleshooting
General Considerations
System Test
If your program fails to run successfully, you can run the 802 Test Program
to check out the host/network/access point/terminal link.
Radio Test
The most basic tool for troubleshooting the Terminal Device's radio is to
check the Signal Strength of the Access Points by pressing the Status Key
and reading the Signal Strength on the last line displayed. Do this test at
about 50 feet or less from the Access point (no walls). If it reads less than
20%, chances are that you have a Terminal Device's radio that needs repair.
Changing Batteries
For RF Terminals, the most frequent cause of problems is low batteries that
have either been ignored or undetected. The real test for batteries is to
remove batteries from a working unit and place them in a suspect unit.
Don’t assume that just because the batteries are new they are good. We
have purchased “new “ batteries off the shelf and tested them immediately
to discover they are bad.
Most of the time batteries become the problem as a result of two failures:
1.
The operator ignores the Low Batteries message and doesn’t finish
up the transaction and immediately change the batteries. If you turn
the unit off and turn it on again, the batteries may have had time to
“almost” recover. Unfortunately they will have so little reserve
power that they will likely operate just long enough to produce some
very screwy behavior on the RF Terminal. Intermittent laser beams,
continuous beeping, black bars on the screen, etc. are just a few of
the disastrous symptoms that can be exhibited.
2.
NiCad or NiMH rechargeable batteries are being used, but the
Terminal thinks that Alkalines are still being used. The Terminal
ships with Alkaline batteries in the Setup. Alkalines and rechargeable
batteries have different reserve powers, so the Terminal has to know
if you have decided to use rechargeables in order to properly notify
you that the batteries have reached the low point requiring the
batteries to be changed.
If you are using rechargeable batteries, you must change the Batteries
parameter in the Terminal Setup to reflect the usage of rechargeable
batteries, otherwise you will strange behavior on the Terminal including:
Intermittent laser beams, continuous beeping, black bars on the screen, etc.
8-1
See Chapter 2: Batteries to change the setting. To display the remaining
battery life of the AA batteries and the type of batteries the Terminal is
expecting, press the STATUS key shows:
AAxBAT










-zz%
x=a when Alkaline batteries are specified in Battery setup
x=n when NiMH or NiCad batteries specified in Battery setup

Radio not Responding
Troubleshooting specific problems
My response time is poor...
• First, do Site Test 50 feet from the Access Point. If it's not 90+%,
the Radio in the Terminal or the Point is the problem.
•
Second, run the 802 Test Program. If it runs fast, your program
that is slow.
•
If you have good response time everywhere but on the outer fringe
area, you may need to add another Access Point.
•
If using the Active X program with XP, be sure "connection
pooling" is disabled.
I'm not getting the distance I need...
To maximize range, the Access Points should be located:
1.
2.
At the center of the area of intended coverage, and
As high as possible - mounted on the ceiling of a room with the
antenna pointing downward works the best. Sometimes just raising
the Access Point to 12 feet will dramatically increase the distance,
especially in warehouses or grocery stores with tall shelving.
Access Points mounted on the wall with the antenna parallel to the
floor is the worst position.
To accurately determine the hardware required to cover a particular
area, you should use Signal Strength shown by pressing the Status Key
on the RF Terminal.

When I turn it on, it just beeps continually.
•
If the batteries are way low, when turned on, the Terminal will just
keep beeping; it is cycling power, over and over because the batteries
are too low.
•
If the batteries are at a specific low point, the laser triggering or
playing a voice message will be just enough extra power draw to
force the terminal to cycle power.
•
Change to known good batteries, preferably out of a working unit
and try again. Some "new" batteries are not good.
The unit won’t power up with batteries (good batteries)
• Your battery terminals inside the case may be corroded with battery
acid or just contamination. Open up the case and clean the battery

covered by the Worth Data warranty.
I get 6 beeps when the RF Terminal powers up...
• The unit needs repair. Call Worth Data for an RMA.
Problems reading Bar Codes
The reader won't beep when I try to read bar codes...
• Try reading a known good bar code - try the 1 on the Setup Menu
bar pad table. Follow the steps for proper scanning technique
discussed in Appendix M; How to scan a bar code.
•
Make sure the reader is configured to read the type of bar code you are
trying to scan. Most bar code types are disabled by default and need
to be enabled using the Setup Menu or keypad while in Setup Mode.
I get extra characters at the beginning or end of my bar code data...
• Clear the Preamble and Postamble settings.
I have very poor read rates when scanning bar codes...
• Carefully follow the scanning instructions in Appendix M; How to
scan a bar code when reading any and all bar codes. As
straightforward as scanning may seem, many people who call with a
complaint about poor read rates simply aren't doing it right.
•
Try reading the following bar code below as an example of a
known “good” bar code. This bar code is a Code 39 bar code and is
8-5
readable by the RF Terminal set to its default settings.
•
Make sure your bar codes have clearly defined dark bars and clean
white spaces. If the bars are so light that they are gray instead of
black or are so dark that they “bleed” into the white spaces, the
printing of the bar codes is the problem. Whoever is printing the
bar codes needs to make the necessary corrections.
•
The bar code should also have a “quiet zone” of at least ¼” to the
left of the first bar and to the right of the last bar. Make sure to
start your scanning to the left of the bar code in the “quiet zone”,
moving the scanner quickly and smoothly as if drawing a line
through the bar code. If using a laser scanner or CCD scanner,
make sure the beam covers the bar code completely.
•
If using a laser or CCD, clean the window of the scanner with a
soft cloth.
If you have a problem…
•
If you have a problem with your RF System, consult the
troubleshooting section of this manual FIRST. As a last
resort before calling for an RMA, you can perform a diagnostic
reset on your terminal. This resets everything back to the
factory defaults, so be prepared to remake any setup changes
(i.e. Terminal ID) you had made prior to the reset.
1. At the SIGN ON prompt, press the F1 key and release it.
2. then press the SHIFT key and release it.
3. press the D key and release (you will now see a menu)
4. press the K key and release.
If you cannot find the answer here, or the diagnostic reset does
not work, call your Dealer or Worth Data for help.
•
Save the shipping box. If you ever need to send the RF
Terminal or any of its’ parts back for repair, us this box.
•
Before you call your dealer or Worth Data for technical
support, have your RF Terminal and related equipment in front
of you and be prepared to explain your problem in detail to
8-6
the Technical Support Engineer.
•
The Engineer may ask you to go through some troubleshooting
procedures while on the telephone. This will help them
determine what is wrong and what the course of action should
be. Many problems can be resolved over the telephone and
will not require that you return the equipment to us. If you
do need to return any of the RF equipment to Worth Data, the
Engineer will issue an RMA number.
•
If you do need to return the RF Terminal for ANY reason, you
MUST have an RMA number first. Write the RMA number
on the outside of the original shipping box and make sure to
insure the shipment. All RMAs should be shipped back to the
following address unless directed otherwise:

Firmware Upgrades
Occasionally it is necessary to get firmware fixes for problems
discovered with the R/F Terminal System.
R/F Terminal Firmware Upgrades
The R/F Terminal firmware can be upgraded by downloading new
firmware into the R/F Terminal from your computer.
Normal Firmware Download for a Terminal
The RF Terminal firmware can also be upgraded by downloading a file
with the current firmware into the RF Terminal's flash EPROM using
the LOADER.EXE program or the RF Terminal EPROM Loader
Windows program found on the 802 Terminal Utilities Disk.
If you have received a disk with the latest firmware or have
downloaded the firmware from our website, www.barcodehq.com,
download the firmware into the R/F Terminal by following the
instructions on the screens of the program for a normal Terminal
firmware update.
The normal firmware update is done through RF. If there is some bug
in the RF communication there is a failsafe firmware download through
the serial port using an F36 Serial Cable.
Failsafe Firmware Download for a Terminal
If the firmware gets completely wiped out, you will get a blank screen
or a blank screen with a cursor in the upper left. There is a failsafe
download still possible, but you will need to open up the RF Terminal
case and move a jumper to the FDL position as shown below.
B-1
After moving the jumper, reassemble the case, plug the power into the
RF Terminal, and connect the F36 Serial Cable to the host computer
and proceed to download firmware using the 802 RF Terminal EPROM
Loader program. Specify a failsafe terminal firmware update and
follow the program's directions.

Appendix C
Code 39 Specifications
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 RF Terminal gives
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 has several advanced features and functions that are discussed
further in this appendix.

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

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
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.

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.

Accumulate Mode
Accumulate Mode is an option allowing the RF Terminal 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.
Accumulate Mode works with Code 39, Code 93 and Code 128 only
and can't be used with a check digit. When the RF Terminal reads a bar
code with a space as the first character, 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. Once
it reads this last bar code, the entire buffer (including that last code) is
transmitted as one long bar code. A “double-minus” sign (--) bar code
clears the buffer. The ENTER code on this Barpad is a Code 39
Start/Stop Character only.
Accumulate Mode must be turned on using the bar coded Setup Menu
or by using the keypad. Accumulate Mode is located in the Code 39

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 (09,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.

. Pairing these control

identical to the pairings for Code 39; Code 39 uses $M to produce a
Carriage Return (ASCII 13) character -- Code 93 uses
Carriage Return.
M to produce the
Code 93's two built-in check digits greatly minimize the possibility of
reader substitution errors. The bar code reader never transmits digits the
check digits. 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.

Codabar Specifications
a12345b
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.
Codabar start/stop transmission
The Codabar section on the RF Terminal 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 Terminal
and data coming from the keyboard. If neither of these situations apply,
you'll probably want to disable it.

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 212345
character 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/EAN128 bar codes always start with a Function Code 1 character. In
addition, a Function Code 1 character terminates all variable length
fields unless they are the last field in the bar code.
The RF Terminal 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). The Mod 10 Check digit is calculated the same as the
Interleaved 2 of 5 example in Appendix D. 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.
F-1
Scanning the appropriate bar codes on the RF Terminal Setup Menu
enables UCC/EAN 128; or you can use the keypad in the
PROGRAMMING MODE “Change Setup” option. 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
If UCC/EAN-128 is enabled on the R/F Terminal reader, all Function 1
codes are transmitted as ]C1. In addition, should you be reading a 20
digit Shipping Serial Container code, the Mod 10 check digit is also
compared with the computed Mod 10 value to give further assurance of
no substitutions. The UCC/EAN-128 Shipping Serial Container Code is a
subset of UCC-128 or EAN-128 adopted for voluntary marking of
shipping boxes with the exact serial number of the box, (used with EDI
typically to identify a specific boxes contents. The code consists of the
following format:

Interleaved 2 of 5 Code
Specifications
123456
Interleaved 2 of 5 Code is a numeric-only, even-number-ofdigits bar code. It is widely used in warehouse and
industrial applications. A combination of five elements, two
wide and three narrow represent each character. Oddnumber 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:
•
Use one length of I 2 of 5 code. Using one length of data
allows you to tell the RF Terminal to look for one length of I 2
of 5 code only. By default, the RF Terminal 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 Terminal Setup Menu. Setting the
length to 00 digits allows variable length bar codes scanning.
If you must use the 00 setting, we recommend that you then
use the “Minimum/Maximum” data length field when creating
a program in the RF Terminal to check each field for the
proper length.
•
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:
G-1
(7 + 9) x 3 = 48
5. Add the results of steps 3 and 4:
9 + 48 = 57
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

Appendix H
UPC / EAN 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. EAN13 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:
Uniform Code Council, Inc.
7887 Washington Village Drive, Suite 300
Dayton, OH 45459
937-435-3870
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.
H-1
•
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
assignedby 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.
Supplemental codes
The UPC standards include the addition of a 2
or 5-character supplemental code as well as the
Extended Coupon Code. To read the
supplements, you must first enable them using
the RF Terminal Setup Menu.
NOTE: Enabling the supplements disallows the reading of UPC codes
from right to left to assure that the 2 and 5 digit supplements are not
get missed. Coupon codes can be read from right to left or left to right.
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 Terminal 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

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
H-3
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).
UPC-E Checksum Calculation
Use the sample data of 123456 to demonstrate the UPC-E checksum
calculation:

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

How to scan a bar code
The RF Terminal can be used with either a laser or a CCD scanner. Which
one you choose is dependent upon your application and the quality and
density of your bar codes. This section will include information on
different scanners as well as how to use each one.
Laser and CCD Scanners
If you are using a laser or CCD scanner, technique is not critical. The
scanners are “point-and-shoot”; you can’t miss. Upon triggering the beam,
the laser and CCD scans the bar code multiple times (36 scans per second)
until it has a good read, at which point it automatically shuts off. These
scanners are more expensive, but virtually foolproof. They read from a
distance, so they are much more convenient for distance shelf scanning or
scanning in tight spots. Different laser scanners have different distance
capabilities. Table M-1 shows the comparison of all the laser and CCD
scanners available from Worth Data.

1.

3.
put your RF Terminal in One-Way mode with the host computer
program not running; or even unplug the serial cable,
point the laser scanner at the bar code at about 6” away.
Pull the trigger (or push the button on an integrated model)
and line up the beam on the bar code. If you don’t get a read,
vary the distance of the scanner from the bar code by pulling
up or moving down. The idea is to scan through the center of
the bar code.
J-1
Laser Options
Several options are applicable to all laser and CCD Scanners that are
used with the RF Terminal. These options are: 1) Longer timeout on
the laser reading, and 2) Double decode required.
Longer Laser Reading: A temporary solution to problem bar codes is
sometimes 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 4second beam:
Scan Start Setup
Scan Laser Options
Scan 3 to select the 4-second beam
Scan End Setup
To return to the default 2-second beam, scan 2.
Double Decode: The default setting for the RF Terminal is one
successful decode results in a “good read”. If you are getting incorrect
reads, (due to defective bar codes), a temporary solution is to turn on
make the RF Terminal perform two straight identical decodes before
beeping, outputting data, and completing a “good read” read.
To activate the double decode:
Scan Start Setup
Scan Laser Options
Scan 1 to select double decode
Scan End Setup
To return to the single decode beam, scan 0.
There are two Setup Options that do not apply to the LZ300. The two
options are:
1.
“Aiming Laser Dot” for a predetermined time before the laser
beam expands into a “line” for reading. The RF terminal
requires a no charge feature to be added to it before shipping
for the Aiming Dot to be used. This feature applies to the
LT70x models of the RF Terminal with its built-in laser and
the external tethered LZ400 Laser Scanner.
2.
“Difficult Code 39 Reading” for reading Vehicle
Identification Numbers (VIN) through the automobile
windshield. This applies only to the external tethered LZ400
Laser Scanner.
Aiming the 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
J-2
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:
From the Keypad, go to RF Terminal Setup. Choose “Other”. Press
Enter repeatedly until you get to the parameter labeled “AIMING
DOT”. The default is 00. Enter the time in 1/10s of a second you wish
the dot to appear before the laser beam spreads, (i.e. enter 30 for 3
seconds).
"Difficult Code 39 Reading":
This setting facilitates reading of difficult Code 39 bar codes such as
the Vehicle Identification Number (VIN number) on automobiles,
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 with a LZ400:
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.
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 itself is wiped clean before
reading
J-3
Appendix K
Using the Scan Stand
Stand mode allows the operator to use an LZ300 laser in “hands free” mode
while attached to an RF Terminal. This is useful in shipping applications or any
application where the operator requires both hands to perform their function.
Stand Mode is actually a fast cycling laser looking for a bar code (many
transitions between black and white). The user scans the bar code on the
Stand to activate it. A scan of the same bar code while in "Stand Mode" will
deactivate it. The "Stand Mode" on the RF Terminal only supports the
external LZ300 Scanner, not the internal scanner and not the LZ400
Scanner. When the scanner detects a suspect bar code, the beam spreads
wider and stays on for 2 1/2 second or until a bar code is successfully read.
If successfully read, the scanner turns off until the next prompt. If no read
occurred, it resumes the cycling looking for a prospective bar code.
When in Stand Mode, if a key is pressed, we assume the user wants to key
data instead of scan data, so the scanner is turned off; at this point the
scanner can be used if triggered. Once the data entry is finished and
transmitted and the next prompt is received from the host program
requesting either 1) scanner only input, or 2) scanner/keyboard input; the
"Stand Mode" operation is resumed.
The Stand itself is available in two models, one with a weighted base (if you
need to move the stand from site to site) or a gooseneck-only model that
must be permanently mounted to a surface.

bends). The warranty is 2 years.
Laser Scanners
The LT802 model RF Terminal is available with an integrated laser
scanner for one-handed scanning. This laser uses the Symbol SE900
Scan Engine with a lifetime warranty on the scan element. We also offer
cabled laser scanners (the LZ300, LZ400 and PSC Long Range) as an
add-on, plugging directly into the SCANNER port of the RF Terminal.
L-1
LZ300 Laser Scanner
This laser scanner uses the Symbol 1200WA Scan Engine with a
lifetime warranty on the scan element. The 10 ft. cable is durability
rated for 1,000,000 bends. It reads all densities of bar codes down to a
3 mil narrow bar and reads a typical UPC code at about 12". The
warranty on the LZ300 is 2 years.
LZ400 Laser Scanner
This laser scanner is the equivalent of the lasers used in the LT802. The
LZ400 uses the Symbol 1200HP Scan Engine with a lifetime warranty
on the scan element. It can read a 10 mil bar code at 17", a 40 mil bar
code at 44 “ ft., and a reflective 100 mil bar code at 9.5 ft. It can read
high density code down to a 3 mil narrow bar width.
This scanner supports the aiming dot mode, useful for difficult aiming
and scanning in bright sunlight.
Durability features include a cable tested to withstand 1,000,000 bends
of operation, as well as a scan engine tested to withstand 2000 G's of
force. It is an extremely rugged product, made to withstand harsh
treatment including repeated drops.
PSC Long Range Laser
This laser is a long-range laser (it reads a 100 mil reflective bar code
from up to 17 ft.), but it also reads normal codes. This makes it ideal for
reading shelves so high you can’t even reach them, (i.e. a forklift
operator can scan the shelves without getting up); but it can still read
desktop bar codes at close range. It actually has two lasers built-in; one
for close up reading, and one for distance reading. It has a two position
trigger; the first position stop is an aiming spot, the second position stop
triggers the beam. Warranty is 2 year.
Laser Accessories
H11 Laser Holder
The H11 Laser Holder is for the LZ300 and LZ400 laser scanners. The
H11 Laser Holder can be mounted vertically (wall) or horizontally
(table top). Double-sided tape is included to use for mounting, or you
can use wood or metal screws (not provided) to mount the holder.

The RF Terminal has a variety of carrying cases and holsters available
for use, depending upon the configuration and function of your RF
Terminal. Choosing the correct carrying case or holster can increase
productivity by making the RF Terminal more accessible and portable.
The RF Terminal can use the following carrying cases and holsters:
F41 Leather RF Terminal Carrying Case
The F41 Leather Carrying Case features either a
shoulder strap or belt loop attachment. The RF
Terminal is worn upside down to make it easier for
the operator to simply
lift the RF Terminal
up and view the
display and keypad in
the correct orientation. The case has
openings for all cable and scanner
attachments, making it unnecessary to
remove the case for uploading. This case has
a clear plastic keypad window to protect the
RF Terminal keypad from the elements.
T46 Holster for RF Terminal
The T46 RF Terminal holster is worn on a belt and
provides a convenient way to store and carry the RF
Terminal during use.
The holster can
accommodate all 700
RF Terminal models
with a boot included.
It provides quick
extraction and
insertion.
Rubber Boot for RF Terminal
The B12 Rubber Boot is shipped standard with
every RF Terminal ordered. It is a rugged,
protective rubber boots intended to protect the
RF Terminal in the most hostile environments.
This boot doesn't have to be removed to
change batteries or connect any of the cables
or recharging power supply.
