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

1-2

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,

Recharge-

ables 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

1-3

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. Turn OFF the R/F Terminal.

2. 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.

3. 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.

4. If using rechargeable batteries, make sure that rechargeables are

specified. See the previous page to quickly determine the setting

using the Status key.

5. Replace the battery door and turn the reader on using the ON/OFF

switch.

6. Sign ON and resume your application.

Recharging the batteries

1. 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.

2. With the RF Terminal shut off, plug the 9V power adapter into the

RF Terminal.

3. The firmware in the terminal then checks the level of charge in the

1-4

batteries to see if they need charging, displaying the following message:

Checking Batteries

Please Wait………..

4. 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

Point with the same SSID

To move on to the first menu item, press any key on the R/F Terminal keypad.

The display now reads:

*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

2-3

• 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:

DEVICE SIGN ON -----1

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 0.0.0.0

Use a Fixed Address 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 0.0.0.0

Use a Fixed Address 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.

Subnet Mask

Default Subnet Mask 255.255.255.0

User Defined Subnet Mask nnn.nnn.nnn.nnn

• If you wish to change the default Subnet Mask of 255.255.155.0, the

enter a new mask in the format of nnn.nnn.nnn.nnn.

Starting Channel

Default Starting Channel 1

User Defined Starting Channel 1-11

• The terminal device's channel should be set to the channel of the most

frequently used Access Point to minimize the initial SIGN ON. The

Terminal Device will try other channels in case the Starting Channel

does not immediately find an Access Point; so this is just to minimize

the time required.

2-6

SSID

Default SSID blank

User Defined XXXXXXXXXXX

• If wish to restrict terminal device to a specific network name, enter the

name here. The default blank setting allows the terminal device to sign

on to any available wireless network. If you want an SSID with lower

case characters, you will have to scan the Full ASCII Menu.

Encryption Method

None 0

64 bit 1

128 bit 2

• For security of the network, Access Points and Devices can be set to a

unique encryption key. This key can be 64 bits or 128 bits long. Here is

where you specify the Encryption Method. The default is None.

Encryption Key

• Here is where you enter the encryption key (WEP). If you specified an 64

bit key, enter the 10 hex number string to use. If you specified a 128 bit

key, enter the 26 hex number string to use. Whatever you enter should

match the Access Point's WEP key.

Control Keys Only

No 0

Yes 1

• Several special keys on the RF Terminal keypad can generate a

response automatically, sending a separate message to the host by

simply pressing the appropriate control key (without pressing the

ENTER key afterward). This allows for simple and fast scrolling by the

operator. The arrow keys, Begin, End, and Search are the specific keys

supported. The default setting is to require the ENTER key to be

pressed before data transmission.

• If you set this feature to 1 (YES), in order for the RF Terminal to

transmit the following values, the corresponding Control Key must be

the first key pressed in a data entry sequence. If it is not the first data

entered, the arrow key is ignored.

• The Start and Stop character for Code 39 is the * character. Settings 6

and 7 determine whether or not those characters are transmitted to the

computer along with the data. For example, at setting 6, the data of

1234 would be transmitted as *1234*. Transmitting the start and stop

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.

• Caps Lock ON causes lower case letters read as data to be transmitted

to the computer as UPPER CASE, and upper case letters to be

transmitted as LOWER CASE. Numbers, punctuation and control

characters are not affected. Caps Lock OFF means that letters will be

transmitted exactly as read. This setting applies to all bar code types.

UPC codes to assure that the supplement code is not missed.

• ISBN (International Standard Book Numbering) bar codes are EAN-13

with a 5-digit supplement. If the “Bookland” bar code uses 978

(books) or 977 (periodicals) as the first three digits, then the RF

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.

• Use setting 4 and 9 to enable transmission of the NSC character to your

computer. The Number System Character is the leading character in

the bar code. For details, see Appendix J, UPC/EAN.

• Use setting 6 and A to enable transmission of the check digit character

to your computer. The check digit is the last character and is based

upon a calculation performed on the other characters.

• Setting C transmits UPC-E0 bar codes as is; setting D transmits them

with inserted zero’s to make them the same length as a UPC-A bar

code. A NSC of 0 is assumed. It is possible to read UPC-E1 bar codes;

by default this option is disabled. Do not enable UPC-E1 if you plan

on reading EAN-13 bar codes; you may experience partial reads when

reading EAN-13. The UPC-E1 option is set in the 2 of 5 Code

Codes

to 8. To turn off UPC-E1 reading, set it back to the default of 9.

• If you prefer to transmit UPC-E bar codes in a 6-digit format while EAN-

8 is transmitted in its original 8-digit format use setting F. This will

allow you to use settings 9 and A and still transmit EAN-8 as 8 digits.

• UPC-A can be transmitted in EAN-13 format by adding a leading 0

• 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

possible. The 00 setting is supplied for the purposes of reading codes

of unknown length, counting the digits and setting the length to the

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. Scan the Preamble bar code or select Preamble from the

keypad menu.

2. Scan the desired characters (up to 15) from the FULL ASCII Menu.

3. Scan the SET bar code, or if using the keypad, press ENTER.

4. 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:

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:

12345678 ~9 12345678

12345678901 ~A 1

123456 ~5 6

Preamble trims leading characters

• 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.

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. Scan the Postamble bar code or select Postamble from the

keypad menu.

2. Scan the desired characters (up to 15) from the FULL ASCII Menu.

3. Scan the SET bar code, or if using the keypad, press ENTER.

4. To clear the Postamble and return to the default (no

Postambles defined), scan CLEAR at step #2, and then

continue with your setup.

Other

2-16

• 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:

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:

Data Postamble Data Transmitted

123 XYZ 123XYZ

12345678 ~3XYZ 12345XYZ

12345678 ~9 12345678

12345678901 ~A 1

123456 ~5 1

Postamble trims trailing characters

• Using the Bar Code ID feature and the Postamble, 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 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 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.

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:

2-17

• Scan Characters

• Scan up to seven 4-digit pairings where the first 2 digits represent the

hex number to replace and the second 2 digits represent the hex

number to insert. You can have up to seven character reassignments.

• Scan SET

You can eliminate the output of a character by using FF as the hex number to

insert. For example, if you wanted to eliminate all $, following the above

instructions, enter 24FF.

Set Date

For correct date display, the 6-digit date must be set in the date format you

plan to use. By default the US terminals use the US date format of

dd/mm/yy. If you change the date format, you must re-set the date to match

the new format. For example, to set a date of January 20, 1999, you would

enter 012099 (US format) or 200199 (European format). The date can be

scanned in from the bar coded Setup Menu or entered from the RF Terminal

keypad. To display the date during operation, press the STATUS key.

Set Time

The time is set using a 4-digit military hhmm format. For example, to set

the time to 3:08 p.m., you would enter 1508. The time can be scanned in

from the bar coded Setup Menu or entered from the RF Terminal keypad.

To display the time during operation, press the STATUS key.

Display of Year

• By default, the RF Terminal is configured to display and transmit the

year in a 2-digit format; i.e. 2005 would transmit and display as 05.

• Before you change the RF Terminal to display a 4-digit year, i.e. 2005,

make sure that the software receiving data from the RF Terminal is set

up to accept a 4-digit year.

Voice Message Partitions

This parameter partitions the total amount of voice messages into different

message lengths. The default setting is:

303015

xx yy zz

where: 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

ones combined.

Shut Down Time

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

all, set the Shut Down Time to 00.

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 4-

second 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

tethered laser scanners. Before the laser beam spreads, you can create a brighter

aiming dot to be sure you are on the bar code you want to read. The default is set

to 00, no aiming dot. You can key in 01 through 99 which creates an aiming dot

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

3-2

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. 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.

2. 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 0-

100, 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.

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.

5-2

• 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 mid-

transaction, 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.

6-1

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 FS (ASCII 28)

DOWN ARROW key GS (ASCII 29)

LEFT ARROW key RS (ASCII 30)

RIGHT ARROW key US (ASCII 31)

BEGIN key ETB (ASCII 23)

END key CAN (ASCII 24)

SEARCH key VT (ASCII 11)

6-2

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.

6-3

• 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. A terminal going out of range and having its power cycled

before returning within range OR

2. 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.

6-4

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 pro-

perties 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.

6-5

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.

InputAny

Parameters: basename, channel, terminal, line, position,

prompt, shifted, timestamped

Function: This instructs the terminal attached to client

basename on channel to display the prompt at line

and position and wait for data to be entered from

either terminal keypad or scanner. If shifted is set to

"true", the terminal will start in shifted mode.

Timestamped appends a (hhmmss) prefix to the

returned data.

InputKeyBd

Parameters: basename, channel, terminal, line, position,

prompt, shifted, timestamped

Function: This instructs the terminal attached to client

basename on channel to display the prompt at line

and position and wait for data to be entered from

the terminal keypad only. If shifted is set to "true",

the terminal will start in shifted mode.

Timestamped appends a (hhmmss) prefix to the

returned data.

InputScanner

Parameters: basename, channel, terminal, line, position,

prompt, allowbreakout, timestamped

Function: This instructs the terminal attached to client

basename on channel to display the prompt at line

and position and wait for data to be entered from

the terminal scanner only. Setting allowbreakout to

true allow user to "breakout" of scanner only mode

6-6

by pressing the end key on the terminal. A

termID+CR will be sent to the host.

InputYesNo

Parameters: basename, channel, terminal, line, position, prompt

Function: This instructs the terminal attached to client

basename on channel to display the prompt at line

and position and wait for a Yes (Enter key or C

key) or a No (0 key or B key) from the terminal

keypad.

Function: This instructs the terminal attached to client

basename on channel to re-initialize. Must be

followed by an "Input" method call to take effect.

6-8

NOTE: Base Stations use the message "Buffer

Reinitialized..." to indicate a single terminal re-

initialization.

ReInitAll

Parameters: basename, channel

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

clients. Results are recorded in the log.

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.

6-9

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!

6-10

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: basename, channel, terminal

Event: The left-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.

OnTermRightArrow

Data passed: basename, channel, terminal

Event: The right-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.

OnTermBeginKey

Data passed: basename, channel, terminal

Event: The BEGIN button has been pressed on a terminal.

You must issue another Input method call before

WDIPterm can respond to another keypress on this

terminal.

OnTermEndKey

Data passed: basename, channel, terminal

Event: The END button has been pressed on a terminal.

You must issue another Input method call before

WDIPterm can respond to another keypress on this

terminal.

6-11

OnTermSearchKey

Data passed: basename, channel, terminal

Event: The SEARCH button has been pressed on a

terminal. You must issue another Input method call

before WDIPterm can respond to another keypress

on this terminal.

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.

6-12

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

RF Terminal ID + T2: DATA + CR

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.

6-13

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:

Part Number Description Price/

Roll

E2L1 2"x1" Vinyl Shelf Adhesive Labels $3.50

E2L2 2"x1.25" Paper Permanent Adhesive Labels $2.50

E2L3 2”x2” Paper Permanent Adhesive Labels $2.50

E2L4 2”x1.25” Vinyl Shelf Adhesive Labels $3.00

E3L1 3"x1" Vinyl Shelf Adhesive Labels $7.50

E3L2 3"x1.75" Paper Permanent Adhesive Labels $5.00

Shelf adhesive labels are designed for ease of removal to facilitate

replacement. Permanent adhesive labels are designed to stick and stay

stuck, making removal difficult without leaving a residue.

Chapter 7

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

7-2

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:

7-3

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

7-4

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

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.

8-2

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

Press the STATUS key again to resume processing.

If using the Active X program with XP, be sure "connection pooling" is

disabled.

Radio not Responding The terminal's radio is not responding, Call for an RMA.

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. At the center of the area of intended coverage, and

2. 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.

RF Terminal Problems

When laser is triggered, it cycles power by itself – 1st screen

When a voice message plays, it cycles power by itself –1st screen

I get black bars on the display when I turn it on

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

terminal s with alcohol soaked cloth. Battery acid leaks are not

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

8-6

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

8-7

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-2

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 specifi-

cations). Code 39 is flexible, features a large character set, variable data

length and density, and bi-directional readability. Code 39 is extremely

accurate; substitution errors are almost nonexistent. Its character set

consists of numbers 0 through 9, upper case A-Z, and characters Space, $,

%. / + and -.

The name "Code 39" comes from both the fact that its

character set originally contained 39 characters (it

now has 43) and from its structure. Each character is

formed of three wide and six narrow elements, made

up of five bars and four spaces. Code 39's density can

vary from a low of .75 characters per inch (cpi) to a

high of 9.4 cpi. There should be a ¼" "quiet zone"

(white space) to 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 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. Assigning a value to each character in the data to be bar coded from

the table as follows derives the check character:

Char value Char value Char value Char value

Mod 43 Check character calculation for Code 39

Here is an example to illustrate how the check character is calculated

for bar code data of 123XYZ:

1. Take the sum of the values assigned to each character:

1 + 2 + 3 + 33 + 34 + 35 = 108

1 2 3 X Y Z

2. Divide the sum by 43: (thus the name modulus 43)

108/43 = 2 with a Remainder of 22

3. Find the character corresponding with the remainder.

M (value 22) is the CHECK CHARACTER

The data becomes 123XYZM, with M added as the Mod-43 check

character.

C-3

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.

This table depicts the Full ASCII character set as a function of Code 39

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

parameters. Choose 4 to Enable or 5 to Disable this feature.

This numeric Code 39 "Barpad" illustrates ACCUMULATE Mode.

Scan 5, 3, 8, and Enter. The RF Terminal transmits a single message of

“538”.

Appendix D

Code 93 Specifications

Code 93 is variable length, continuous, bi-directional, compact code. Code

93 is an alphanumeric bar code which consists of 43 data characters (0-

9,A-Z,$/+%.- and Space), 4 control characters, and a unique start/stop

character. The entire set of 128 ASCII characters is represented in Code 93

using combinations of control characters and data characters.

The control characters are , , , and . Pairing these control

characters with normal data characters creates full ASCII 93. 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. 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.

Appendix E

Codabar Specifications

Codabar is widely used in libraries, blood banks, the

cotton industry and transportation industries. Its'

character set consists of numbers 0 through 9, and

punctuation characters + . - / : and $. Symbols a, b,

c, d, t, n, * and e are used as start and stop

characters. Characters are constructed of four bars

and three spaces.

Codabar is a numeric-only code, but different combinations of start and

stop characters can be used to identify different types of labels.

Codabar's variable data length and extremely low error rate make for a

versatile bar code.

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 2-

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/EAN-

128 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.

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:

Start C not transmitted

Function Code 1 transmitted

2 Digit Qualifier transmitted

7 Digit Data Portion transmitted

1 Digit Mod 10 Check Digit* transmitted-

1 Digit Modulus 103 not transmitted

*Calculated using 19digits-UPC method

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

Interleaved 2 of 5 Code

Specifications

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:

• 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:

123456

G-2

(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

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. 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:

Uniform Code Council, Inc.

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-2

• 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).

2 Store-marked random weight items of meat and

produce.

3 Reserved for National Drug Code and Health Related

Items.

4 Use this leading digit for in-store marking of non-food

items.

5 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

data:

18314589938

Assign even and odd positions, starting at the right and moving left:

8 3 9 9 8 5 4 1 3 8 1

odd even odd even odd even odd even odd even odd

1. Starting with the leading digit, 8, take the sum of all the

characters in the odd positions.

8 + 9 +8 + 4 + 3 + 1 = 33

2. Multiply the result of step 1 by 3.

33 x 3 = 99

3. Now take the sum of all the even-position characters.

3 + 9 + 5 + 1 + 8 = 26

4. Add the result in Step 2 to the result in Step 3.

99 + 26 = 125

H-4

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:

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

Position 10 digit code

0 abcde0 00000 3 ab00000cde

1 abcde1 10000 3 ab10000cde

2 abcde2 20000 3 ab20000cde

3 abcde3 00000 4 abc00000de

4 abcde4 00000 5 abcd00000e

5 abcde5 0000 6 abcde00005

6 abcde6 0000 6 abcde00006

7 abcde7 0000 6 abcde00007

8 abcde8 0000 6 abcde00008

9 abcde9 0000 6 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:

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

I-2

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:

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.

Table M-1. Scanner Comparison Chart

6 mil = high density 40 mil = low density 100 mil = very low density (with paper and retro-reflective label stock)

To scan a bar code using your laser or CCD scanner, (whether it be a

handheld or integrated)

1. put your RF Terminal in One-Way mode with the host computer

program not running; or even unplug the serial cable,

2. point the laser scanner at the bar code at about 6” away.

3. 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.

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 4-

second 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-3

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

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.

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.
