Introduction

The 7001 RF Terminal is a low cost, easy-to-use radio frequency interactive terminal which communicates with PCs (or any computer) by RS-232 serial port. This new terminal offers unprecedented power and ease of use, while maintaining compatibility with programs written for the older Worth Data Terminals. The list of fantastic features include:

•Low Cost

•Up to 3.3 mile range, LOS (10 x the competition)

•64 Terminals per Base Station

•Spread Spectrum frequency hopping avoids interference

•No license required in USA and Canada

•Small size, (5.9" L, 3.6" W, 1.0" D) even with laser

•Certified to multiple 5 ft. drops to concrete

•Long Battery Life (15 hours of usage)

•Fast Recharging (2-3 hours) from External Power Supply

•No programming necessary on terminal

•Host communication thru RS-232 Serial

•User Customizable Voice Prompting plus Display

•Backlit Color TFT Display Standard

•Uses Li-Ion battery

The RF Terminal maintains software compatibility with applications written for the older generation T71/LT71 and T701/LT701 RF Terminals. Differences are noted below.

Differences

While the new 7000 series RF Terminals are fully software compatible with the older 70 and 700 series terminals, there are a few differences between them. The differences between the older generation of Worth Data RF Terminals and the generation referred to within this manual are:

•64 Terminals per Base Station instead of 16. Valid Terminal ID's are 0-9, A-Z, a-z, - and =.

•Valid Channels are 0-5.

•Base Station parameters (Baud Rate, Parity, Security Code, etc) are not set through the Terminal, but rather set with a Windows program.

•The maximum number of characters that can be sent to a Base Station by a host program is 231 instead of the old 247.

•Speaker volume is controlled by the RF Terminal's Setup menu.

•The 7000 Series does not have a choice of battery types. It comes with a built-in Li-Ion rechargeable battery. The battery is charged by the same power supply that is used with the Base Station. An adapter cable is provided to allow connection to the RF Terminal.

•Voice prompts are now recorded on the PC and uploaded to the RF Terminal using the Voice Prompt utility. Up to 99 voice prompts can be stored in the RF Terminal with a total time of about 90 seconds.

•

Some differences are simply advantages:

•Greater range (3.3 miles line-of-sight vs. 3000 feet line-of-sight).

•Optional “gun” handle with secondary battery that doubles operational time.

•Color TFT display standard

•Faster transaction times.

Installation

Components

The components in your R/F Terminal system will vary according to the configuration of your system. Your R/F Terminal shipment should contain at least:

•An RF Terminal T7001 or LT7001 - If the R/F Terminal is an LT7001 model, it will have an integrated laser scanner built-in to the body of the terminal.

•Serial Cable – for programming and voice prompt upload.

•5V Power Supply – battery charger with adapter cable.

•Utilities CD ROM – demo programs, DLL, and firmware loader program

If Base Stations were ordered with your system, you should receive at least:

•A Base Station (B5001) including a 5v power adapter for each.

•A Serial Cable (F34 or F36).

•A Relay Test Cable and junction connector block if ordering bases as Relay Stations.

Installation Sequence

1.Start with one Terminal and Base Station. Get everything working with the single terminal and base and then add other terminals, being certain that all terminals have unique Terminal IDs. After all terminals are working, add the first relay. Then add remaining relays, remembering to: 1) assign Relay IDs, and 2) set the jumpers of each relay to terminated or not terminated properly.

2.All equipment is shipped with the default setting of Channel 0, Terminal ID 0, and Relay ID 0. Unless you have other Terminal/Base configurations already operating on that channel, you probably don’t need to change the channel.

3.A Base and a Relay are the same product. A jumper change is all that is required to use a Base station as a Relay. See Appendix A for details.

4.Without attaching the Base Station to the computer, and with only the power supply plugged in the base, you can perform a site test to be sure you have adequate coverage and the radios are working perfectly. (See

Chapter 4).

5.Now connect the Base Station to the computer’s serial port. Be sure to turn OFF all handshaking on the COM port used; in Windows, go to Start Menu, Settings, System, Device Manager, Ports (COM and LPT). Now run one of the RF Terminal demo programs found on the Utilities CD-ROM.

6.Now run one of the demo programs to validate that everything is working. If you have problems, refer to the Trouble Shooting Section.

Connecting the Base Station to a serial port

How it works…

The R/F Terminal transmits data to the Base station, which in turn transmits the data to the host serial port. The computer software reads the data coming through the serial port and processes the information accordingly. When the computer software running on the host has a task for the terminal, it transmits data

out to the serial port, which then passes this data on to the Base station. The Base station then broadcasts the message to the terminal, causing the terminal to display the message to the user.

The Base station is not machine-sensitive (it needs a standard RS-232 serial port) nor is it operating system dependent (you just need to be able to read and write to the serial port as a separate device).

Connecting the Base station…

If you specified a 25 pin cable (part #F34) or a 9 pin cable (part #F36) when you ordered your Base station, simply plug the RJ45 end of that cable into the COMPUTER port on the Base station, and the 25 or 9 pin end into your computer’s serial port. If you are not connecting to a PC, see Appendix C for cable and serial pin-outs.

For an extension cable, you can use existing network cabling already in existence, but you must be certain that the Transmit and Receive data lines are not in the same twisted pair.

If you are using an extension cable and are having problems, test the cable by:

1.Connecting the Base station without using the extension cable. Simply plug in the F34 or F36 cable that came with the Base.

2.If the Base works with only the F34 or F36 cable in place, add in the extension cable without changing the physical location of the Base station. If the extension cable appears to be the culprit, check to be sure that Transmit lines are connected to Receive lines.

Configuring the Base station…

After connecting the Base station to your serial port, you need to configure the serial settings on the Base station to match those required by your software. The default settings are:

•9600 baud

•No parity

•8 data bits

•1 stop bit

•“None” protocol setting

You may want to increase the baud rate for performance. If you want to change any or all of these settings, see Chapter 2 for details on configuring the Base station using the 700 RF Base Station Serial Configuration Utility.

Base station channel…

To determine what channel your Base station is set to, plug in the power supply and watch the LED light on the front of the Base station. The LED will blink “the channel + 3” times.

For example, the default channel is 0. On power up, the LED on a Base station set to channel 0 would blink 3 times. A Base station set to channel 5 would blink 8 times.

If this is the only Base station operating, leave the channel at 0. If you have other Base stations in the area and need to change the channel, see Appendix A; Channel and Jumper Changes for details on how to open the Base station and set the rotary switch inside to the desired channel.

R/F Terminal Operation

Using the RF Terminal keypad…

The R/F Terminal is turned on by pressing the green ON/OFF button located in the upper lefthand corner of the R/F Terminal keypad.

It is a good idea to fully charge the R/F Terminal before you use it the first time to make sure the battery charged. See below for more information on battery charging.

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 nonshifted state, and alpha characters in its shifted state. You can readily determine if the SHIFT is on by the cursor on the display. When SHIFT is on, the cursor is a large 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.

Battery Life Indicator

The R/F Terminal detects low battery and displays the following message:

LOW BATTERY

Charge Battery

Hit Any Key_

At this point you have approximately 10% of battery life remaining. You should complete what you are doing and charge the battery soon. When the battery is too low to operate the unit properly another message is displayed:

Battery too Low to Operate

Hit Any Key to Power Down

If you turn it back on without charging batteries, you may experience constant beeping, intermittent scanning, and very irritating symptoms that look like equipment failure.

The R/F Terminal also has a battery life indicator that can be accessed while operating in ONE-WAY or TWO-WAY mode or while in the MENU. To display the remaining battery life of the battery (as well as the date and time) press the STATUS key:

mm/dd/yy hh:mm:ss BATTERY: |||||||||||||||||||| zz% R7Uxxx ID=0 CH=0 RL=N SC=N RF=8C C=N

zz=percent in numbers i.e. 99, 10, 05

Press the STATUS key again to resume processing.

The lifetime of the R/F Terminal's Li-Ion battery is 500-1000 charge cycles. If the battery runtime seems to

be significantly shorter than when the device was new, the battery should be replaced. If you have the optional “gun” handle with the extended battery then both batteries should be replaced at the same time. The main battery is a common digital camera battery sold as Fujifilm NP-120 or Pentax D-LI7. We use a high quality Japanese Li-Ion cell in our OEM pack that we supply with the R/F Terminal. You can obtain a replacement from Worth Data (P/N: L02) . Our pack is rated at 1950 mAh and provides the longest runtime available. Do not use a battery pack of unknown quality or origin. Doing so can risk damage to your unit. The optional handle battery is custom made for Worth Data and must be ordered from us.

Your old battery should be recycled. You can get free recycling information at: http://www.rbrc.org/

To change the internal battery:

1.Turn OFF the R/F Terminal.

2.Remove the battery holder door on the back of the R/F Terminal by removing the two screws holding the door in place..

3.Remove the old battery and insert a new one, making sure to orient the battery with the battery contacts facing the battery connector.

4.To replace the optional handle battery, remove the 2 screws holding the handle in place. Unplug the handle battery assembly.

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

6.Sign ON and resume your application.

Recharging the battery:

1.With the RF Terminal shut off, plug the 5V power adapter into the RF Terminal using the supplied adapter cable.

2.The RF Terminal will turn On and display the following message:

Charging Battery

Please Wait………..

3. When the battery is fully charged after 2-4 hours the following messaged is displayed:

Battery Charge Complete

4.The unit will remain ON for a half hour or so after the charge cycle has completed and then turn OFF.

5.If you press the POWER key while the unit is charging, nothing will happen.

6.If you press the POWER key after the unit has turned OFF after completing a charge cycle and the charger is still attached, the “Charging Battery” message will display again and a charge cycle will begin.

7.It will take about 2 hours to fully charge a unit with a single battery and about 4 hours to fully charge a unit with the optional handle battery.

8.Do not charge the battery if the Terminal is very hot or very cold since this will give a false reading on the condition of the battery and it may not get charged properly.

9.You cannot operate the unit when the charger is attached, except to charge the battery.

R/F Terminal Menu Functions

Upon power-up, the R/F Terminal displays the following opening screen:

R/F TERMINAL LT7001

FIRMWARE: Uxxx – HWyy-Rzz

USA CHANNEL: 0 TERM ID: 0

HIT ANY KEY TO CONTINUE

(The opening screen can be bypassed upon power up. See Chapter 2)

•On second line on the screen, FIRMWARE: Uxxx, gives the firmware revision number. The letter U indicates USA frequency. Rzz refers to the version of the radio processor firmware.

•HWyy indicates the version of the hardware.

•TERM ID: 0 refers to the current Terminal ID. The default setting is 0. Every Terminal must have a unique ID.

•Line 3 refers to the channel currently used by the R/F Terminal. USA CHANNEL: 0 refers to a Terminal set to channel 0.

To move on to the main menu, press any key on the R/F Terminal keypad. The display now reads:

•Press the 1 key to SIGN ON to a two-way communication host computer program through the Base station.

•Pressing 2 enters the Setup Mode for the R/F Terminal or Base station.

•Press 3 to enter ONE-WAY mode. ONE-WAY mode allows the R/F Terminal to transmit data to the host computer without prompting from the host computer program – we call this “dumb” data entry. (If you want a Terminator Character on the bar code, you will have to enter a Postamble using the Setup Menu). ONE-WAY mode is also useful for demos, as it does not require any interaction from the host computer.

•Press 4 to enter SITE TESTING. SITE TESTING is an excellent way to assess your R/F communication in any area. It can help you determine the best place to locate your Base station for maximum R/F performance as well as troubleshoot problems that may relate to range or interference.

You can back-out of any mode or prompt by pressing the F1 key. For example, if you select SETUP MODE but really want ONE WAY MODE, press the F1 key to take you back to the menu. The F1 key on the R/F Terminal keypad works like the ESC key on the PC – it will usually get you out and back to the previous

(requires GWBasic or QBasic)

step. You can use the F1 key to exit and SIGN OUT when using a Two-Way communication program running on the host computer.

The entire mode menu can be skipped (see Chapter 2; RF System Setup), causing the R/F Terminal to automatically SIGN-ON or go to ONE-WAY mode on power up.

Once you have selected a group to edit, you will see each parameter displayed in the order listed above. Use the next section of this chapter as a reference for all RF Terminal Setup Parameters.

RF Configuration

Default settings are shown in bold type.

The RF Terminal will typically require no setup changes except, Terminal ID (if more than one terminal) and enabling bar codes to be read other than UPC or Code 39.

RF Terminal ID

Default ID	0
Available ID's	0-9, A-Z,
	a-z, - =

•Every terminal needs a unique Terminal ID. The default Terminal ID is always shipped as 0. If you have more than one RF Terminal assigned to a Base Station, you must be sure that each RF Terminal has a unique Terminal ID, (otherwise you will have big troubles including false error messages). The Terminal ID is always displayed on the Start Up screen when you power up the terminal. There are 64 Terminal ID's available - 0-9, A-Z, a-z, and the special characters "-" and "=". To change the Terminal

ID, select option 2 on the keypad after which a box will appear where you can enter the desired Terminal ID. Enter one character for the Terminal ID.

RF Terminal Channel

Default Channel

0

•The terminal's radio operates by "frequency hopping" spread spectrum. The radios hop from one frequency to another using a pseudo-random sequence. The radio goes through 26 different frequencies and then repeats the sequence – all in the 902-928 MHz band at 250 milliwatts of power. Different sequences define the channels. It is possible to have more than one RF Network in the same area, providing each RF Network is on separate channels to avoid interference and general confusion.

•The default Channel is always shipped as 0. There are 6 channels in the USA. The Channel can be set by pressing the 1 key when in the RF Configuration menu. Each time you press the 1 key the Channel will increment through the 6 possible channels.

All Terminals, Base Stations and Relays in the RF Network must be set to the same channel. The channel is always displayed on the Start Up screen when you power up the Terminal. It is possible to have more than one RF Network in the same area, providing each RF Network is on separate channels to avoid interference and general confusion.

Security Code

Security Code	OFF
Available security codes	3 characters

•A Security Code can be utilized to minimize the possibility of a Base Station listening to data from a Terminal that is talking to a different Base Station. A Security Code can also prevent interference from having many Base Station/RF Terminal configurations in one area; i.e. a merchandise mart with multiple vendors all running RF Terminal networks.

•A Security Code consists of 3 characters - any combination of ASCII 33 - ASCII 126. This allows for the possibility of more than 830,000 different character combinations. The characters are entered using the bar coded FULL ASCII MENU provided in Appendix O; ASCII Code Equivalent Table.

•Once you press 3 to enable the Security Code, you will see 3 boxes appear where you can enter the desired security code. Pressing the CLEAR key will reset the Security Code to the default value which is OFF. You can enter any key on the keypad. If you press the shift key the cursor will turn RED and you can enter any of the shifted values on the keypad.

To enter characters that are not on the keypad, use the FULL ASCII MENU provided in Appendix O.

Skip Opening Screens

OFF

Go to Two-Way (TWO WAY)

Go to One-Way (ONE WAY)

Many users want to skip the opening screens and go directly to TWO WAY or ONE WAY communication once their programs are fully operational. Selecting TWO WAY or ONE WAY will automatically take the operator to the corresponding mode and into your application, skipping the usual Mode Menu. If you want to return to the Mode Menu at any time, simply press the F1 key.

Control Keys Only

Control Keys Only	Off
Control Keys Only	On

•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 ON, 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.

Control Key on RF Terminal	Code transmitted to Host
Up Arrow	FS (ASCII 28)
Down Arrow	GS (ASCII 29)
Left Arrow	RS (ASCII 30)
Right Arrow	US (ASCII 31)
Begin	ETB (ASCII 23)
End	CAN (ASCII 24)
Search	VT (ASCII 11)

The message is sent to the host as:

Bytes	Function	Value
1	RF Terminal ID	0-9, A-Z, a-z, - =
2	Data Transmitted	ASCII Value from Table Above
Last	Terminator of Message	CR

Automatic Check Back

This parameter should not be changed under normal circumstances. After the host sends a prompt, the Terminal goes to sleep waiting on the operator to key or scan input in response to the prompt. It waits until the Automatic Shut Off time or until the operator responds. This parameter sets the time that the Terminal stops waiting on input from the operator, discards the current prompt, and goes back to the host to see if there is a change in instructions. If no change, the host must resend the prompt again because the Terminal has discarded the original prompt. The host now has the opportunity to change a prompt. The time can be set in increments of 5 seconds, up to 495 seconds. The default value is 00. The values possible for entry are 0099. An entered 99 gives 99x5 seconds, or 495 seconds between check backs. The Terminal sends back an ASCII 07 for the data back to the host (ID ASCII 07 CR). To change this value press the 6 key in the RF Configuration menu and enter the 2 digit value desired.

Transmit Start Stop	ON	OFF	4
MOD 43 Check Digit	ON	OFF	5
Transmit MOD 43	ON	OFF	6
Caps Lock	ON	OFF	7
Decode Option		0, 1, 2	8

•The Start and Stop character for Code 39 is the * character. Setting 4 determines whether or not those characters are transmitted to the computer along with the data. For example, at setting ON, 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 (6) will send the check digit data along with the rest of the bar code data to your computer. To use 6, you must also be using 5.

•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.

•See Appendix E; Code 39 for more information regarding Accumulate Mode.

•Decode Option is used to allow reading of Code 39 bar codes through a windshield. Setting this option to 1 will loosen up the decoder a little and option 2 will loosen up the decoder a bit more. This should be used with caution since using a looser decoder can cause substitutions.

UPC-A / EAN-13 Options

•Use setting 2 to enable reading of the 2 and 5 digit UPC/EAN supplements commonly found on magazines and paperback books as well as the Extended Coupon Codes. Using this setting force left to right reading of UPC codes to assure that the supplement code is not missed.

•Use setting 3 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 4 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.

•Use setting 5 to enable the transmission of the EAN-13 country code (the first 2 digits).

•Use setting 6 to enable the transmission of the EAN-13 check digit.

•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. To enable transmission of the ISBN format, set option 7 to ON. To return to the default of normal EAN-13 transmission, set option 7 to OFF. For details on ISBN, see Appendix J, UPC/EAN.

•UPC-A can be transmitted in EAN-13 format by adding a leading 0 (USA county code) to the UPC-A data. To transmit in EAN-13 format, set option 8 to ON.

UPC-E / EAN-8 Options

UPC-E First Digit	ON	OFF	1
EAN-8 First Digit	ON	OFF	2
UPC-E Check Digit	ON	OFF	3
EAN-8 Check Digit	ON	OFF	4

UPC-E1	ON	OFF	6

•Use setting 1 and 2 to enable or disable the UPC-E or EAN-8 first digit.

•Use setting 3 and 4 to enable or disable the UPC-E or EAN-8 check digit. The check digit is the last character and is based upon a calculation performed on the other characters.

•Use setting 5 to select UPC-E0 compressed or expanded. When set to ON (the default setting) UPC-E1 codes are transmitted as is, when set to OFF UPC-E1 codes are transmitted with inserted zero's to make them the same length as a UPC-A bar code. A NSC of 0 is assumed.

•Use setting 6 to enable the reading of UPC-E1 bar codes. Do not enable UPC-E1 if you plan on reading EAN-13 bar codes. You may experience partial reads when reading ENA-13.

•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, set option 7 to ON.

Code 128

Code 128	ON	OFF	1
UCC/EAN 128	ON	OFF	2

• UCC/EAN-128 is a subset of Code 128 that follows certain specifications regarding character content, length and check digits. Enabling UCC/EAN-128 (2) causes the RF Terminal to look for a Code 128 bar code that begins with the Code 128 F1 (Function 1) character. See Appendix H: Code 128 for more details.

Codabar

Codabar	ON	OFF	1
Codabar CLSI	ON	OFF	2
Start Stop Character	ON	OFF	3

•CLSI is a form of Codabar often used by libraries.

•Setting 3 will transmit the Codabar start and stop characters with the bar code data to your computer. If you are varying the start and stop characters to differentiate between different labels, transmitting the start and stop can be helpful. See Appendix G; Codabar for more information.

Interleaved 2 of 5	ON	OFF	1
Check Digit	ON	OFF	2
Transmit Check Digit	ON	OFF	3
Standard 2 of 5	ON	OFF	4
2 of 5 Code Length		06	5

•Setting 2 requires that the last digit in your bar code conform to the specifications for the 2 of 5 check digit calculation. See Appendix I; 2 of 5 Code for more information.

•Transmission of the check digit (3) requires the use of setting 2 and will transmit the check digit along with

the bar code data to the computer.

•2 of 5 is so susceptible to misreads that the RF Terminal adds an additional safeguard - it can be configured to look for fixed-length data only.

•The default setting of 06 causes the RF Terminal to read only 2 of 5 codes that are 6 digits in length. To set the RF Terminal to read a different length, enter any two-digit number. 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 proper number.

RS-232 I/O Settings

Baud Rate

Use the 1 key to select the baud rate. The default value is 9600. The available baud rates are 2400, 4800, 9600, 19200, 38400, 57600 and 115200.

Parity

•Use the 2 key to select the parity.

•The options are None, Even or Odd.

•None is generally used with 8 data bits

•Even or Odd parity is generally used with 7 data bits.

Data Bits

• Use the 3 key to select either 8 or 7 data bits.

XON / XOFF Printer

• Setting 4 pertains to use of a serial Printer with your RF Terminal. Use key 4 to enable XON / XOFF if

your serial Printer supports it. It DOES NOT apply to the Cameo and QL3 Printers.

•Settings E and F pertain to the way the RF Terminal handles illegal statements coming from the host computer. RF Terminal software versions prior to 9.059 did not handle illegal statements the same way as current versions. This setting is really only applicable if you had written your host program to be compatible with RF Terminal versions prior to RFT9059.

Date & Time Setting

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

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, 2009, you would enter 012009 (US format) or 200109 (European format). To display the date during operation, press the STATUS key.

Date Format

US Format	0
European Format	1

•The US format of mm/dd/yy is the default setting.

•If you switch formats, you must reset the date (SET DATE) in the new format also.

Year Output

2 digit	0
4 digit	1

•By default, the RF Terminal is configured to display and transmit the year in a 2-digit format; i.e. 2009 would transmit and display as 09.

•Before you change the RF Terminal to display a 4-digit year, i.e. 2009, make sure that the software receiving data from the RF Terminal is set up to accept a 4-digit year.

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 enter two digits - the default is 05 (5 minutes)- to correspond to the length of time in minutes. For example, 01 would be 1 minute. Setting the Shut Down Time to 00 will disable automatic shutdown.

Keypad Tone

Keypad Tone ON OFF 4

The “Keypad Tone” is the key click that you hear each time a key is pressed. Press the “4” key to toggle this On and Off.

Laser Options

Double Decode

Double Decode ON OFF 1

•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.

4.5 Second Laser Beam

4.5 Second Laser Beam ON OFF 2

• 4.5-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. The default beam time is 2 seconds.

Aiming Dot Duration

Aiming Dot Duration (in 1/10 seconds)

00 – 99

3

•This parameter applies to the built-in internal laser. 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 in 1/10th second increments; i.e., 20 would be two seconds.

LCD Options

4 / 6 Line Legacy Mode

6 Line Legacy Mode	OFF	1
4 Line Legacy Mode	OFF	1

The LT7001 is backward compatible with the LT701 6-Line and 4-Line display modes. This will enable you to use the LT7001 without making any changes to your software that you use with your LT701. This is host software compatibility only and the LT7001 will not communicate with the B551 Base Station.

Background Color

Background Color 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F 2

The default background color can be set to one of 16 different values. Each time you press the “2” key a small rectangle will show the selected background color with the current text color. The default value is 1 for Black. You can find more information about colors in chapter X.

Text Color

Text Color 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F 3

The default text color can be set to one of 16 different values. Each time you press the “3” key a small rectangle will show the selected text color with the current background color. The default value is 2 for Blue. You can find more information about colors in chapter X.

Brightness

Brightness LOW, MED, HIGH

The default brightness of the LCD is medium which works well for indoor use. In high ambient light areas, like outdoors, you may want to increase the brightness of the display. Increasing brightness shortens battery life.

Brightness Timeout

Brightness Timeout (in seconds)

00..05..99

This setting controls the timeout for the display to dim after a key is pressed or data is displayed on the LCD. The dim setting is the same as the LOW brightness setting so if you have the brightness above set to LOW you will not see any effect from the timeout. Dimming the display helps extend battery life. The default is 05 for 5 seconds. A setting of 00 will disable the timeout and keep the display always at the standard brightness level.

Other Settings

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 entered from the keypad or scanned from the bar coded FULL ASCII Menu. To set a preamble:

1.Select option “8” from the RF Terminal Setup menu then “1” for Preamble from the Other Settings menu.

2.Enter the desired characters (up to 15). Pressing the shift key will turn the cursor red to indicate that the shift is active. Pressing shift again will turn the cursor white and return to unshifted mode.

3.Press “ENTER”.when you are finished entering data.

4.To clear the Preamble and return to the default (no Preamble defined), press “CLEAR”.

You can use the Preamble to trim characters from the data you are entering into the RF Terminal. You can trim from 1-15 characters from the data by creating a preamble of:

~x

where ~ is ASCII 126 and x is a single hex digit 1-F (corresponding to 1-15). Data that is shorter than the trim amount is transmitted without trimming. Preambles trim characters from the front of the data. Here are some examples:

Data	Preamble	Data Transmitted
123	XYZ	XYZ123
12345678	~3XYZ	XYZ45678
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 maxi-mum 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.

To set a Postamble:

1 Select option “8” from the RF Terminal Setup menu then “2” for	Postamble from the Other
Settings menu.

2 Enter the desired characters (up to 15). Pressing the shift key will turn the cursor red to indicate that the shift is active. Pressing shift again will turn the cursor white and return to unshifted mode..

3 Press “ENTER”.when you are finished entering data.

•To clear the Postamble and return to the default (no Postamble defined), press “CLEAR”.

•You can use the Postamble to trim characters from the data you are entering into the RF Terminal. You can trim from 1-15 characters from the data by creating a Postamble of:

~x

where ~ is ASCII 126 and x is a single hex digit 1-F (corresponding to 1-15). Data that is shorter than the trim amount is transmitted without trimming. Postambles trim characters from the end of the data. Here are some examples:

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:

•Select option “8” from the RF Terminal Setup menu then “3” to enable character entry. A square cursor will appear.

•Enter 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.

•Press “Enter” when done or “Clear” to reset to none.

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.

System Tools

Download File

This will allow you to download a new voice prompt file or a firmware update. You must run the utility program on the PC to download the file.

Play Voice Prompt

To play a voice prompt, select option “2” then enter the 2-digit number of the voice prompt that you wish to play. The valid range is 01 to 99.

Reset to Factory Default

Select option “3” to reset all setup values to the factory default values. This will reset all values in all menus of the RF TERMINAL SETUP.

Base and Relay Setup

The Base and Relay Setup is only accessible via the RF 7000 Configuration Utility included on the Utilities CD that came with your RF Terminal. You can also download the utility from our website at:

http://www.barcodehq.com/downloads.html

Using the RF 7000 Configuration Utility

After you install the Configuration Utility from the CD or from the web, make sure your Base Station or Relay is attached to one of the computer COM ports using the 9 pin serial cable (F36) cable included with your system and that the power supply (5v from Worth Data ONLY) is plugged in. A Base Station will light the LED Green, while a Base jumpered as a Relay will light a the LED Yellow, so be sure your unit is jumpered properly.

Start the RF 7000 Configuration Utility.

If you know which COM port you are attached to, select that port in the program, then click "Continue". If you are unsure of the COM port number, the program can find it for you. Enter the range of COM ports to search, then click "Find Base Station".

The program will look for the Base or Relay and determine its current configuration. Once the program finds it, it will display the Device Type (BASE or RELAY), the RF Channel (default is 01) and the Firmware Version (xxxxx-pp). The first five characters are for the main processor's firmware, which can be updated by you from the latest firmware always available on our website. The last two last two characters are the firmware version of the radio processor; this is not field updateable. If these two characters don't show, (you see only xxxxx), it means your radio processor is not responding and you need to call us to authorize a repair.

If you want to change any of the settings (Baud, Parity, Data Bits and Stop Bits), you can do so by clicking the desired setting.

If you are configuring a Relay, the first Relay should be configured as Relay ID "0", which is the default. If you have more than one Relay, then select the desired Relay ID for this unit.

You can enable a Security Code for either a Base or a Relay. The Security Code needs to be three characters and when enabled, requires anyone wanting to make a change to the Base or Relay to enter this 3-character code.

"Xon/Xoff Sensitive" should be checked ONLY if your system has XON/XOFF specified for handshaking on the serial port in use. Typically in Windows, handshaking will be set to "None" and you should leave this setting unchecked. See "Addressing a Terminal not Signed In" and "Base Station Initialized Message" in

Chapter 6 for details.

Once you have made any and all changes, click on the "Send Settings" button. Your Base or Relay is now configured!

Testing the RF link between base station and host

Use the following command to test the transmission of data from host to Base and back again to the host:

@@*Edataaaaaaaa<EOT>

where dataaaaaaaa is any string of data, terminated by EOT. This string should be sent from the host to the Base Station. If the data is received by the Base, it is echoed back to the host in the format:

dataaaaaaaa<CR>

where dataaaaaaaa is the data string from the original transmission, terminated by a CR (ASCII 13). This test verifies communication in both directions (host to Base, Base to host).

•If the data isn’t echoed back, either your host COM port or the Base Station has a problem.

•Once you know the Base Station is communicating with the host correctly, compare the channel of the Base Station with the channel of the Terminal. Use Site Testing to check the communication of the Terminal to the Base and back. Stay close, make sure no other Terminals are in use, and go to Site Test mode on the Terminal. You should get 90-100% on first try. If you don’t, it’s a good chance your radios need repair. Call Worth Data for an RMA.

If you are using PICK or UNIX as your operating system, make sure the Base Station is set to "XON/XOFF Sensitive".

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. The RF Terminal has three different modes of communication:

•Two-Way Mode - the host program transmits requests for data to the terminal via the Base Station. The RF Terminal transmits a response back to the Base Station, which in turn sends the data on to the host program. This is a truly interactive mode allowing you to create flexible programs for a variety of applications that are computer led and controlled.

•One-Way Mode - the RF Terminal transmits to the host with only confirmation from the Base Station. The host program receives data from the Base Station as it would any other serial device. The host cannot send data to the terminal; it can only receive information.

•Site Survey Mode – the Base Station and RF Terminal work together to evaluate the site and determine

the best location for the Base Station. The site survey evaluates the signal strength of a number of test packets that are exchanged between the Base and Terminal. The higher the number, the more successful your communications will be from that area. This helps you to identify problem areas before you implement your RF Terminal system. At 30 ft., this is also the acid test for suspected bad radios in a base or in a terminal.

Let’s start with a discussion of the basic theory behind a Two-Way RF Terminal system.

How the Two-Way RF System works

Basic RF System communications…

The RF system consists of three components – Host Computer, Base Station and RF Terminal. The Base Station connects to the Host Computer via the serial port. The application running on the Host Computer sends a data prompt to the com port where the Base Station receives it. The Base Station then transmits the data prompt via radio frequency to the intended RF Terminal. 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 Base Station, which in turn passes it on to the Host Computer. The application on the host computer processes the information and sends a new data prompt out to the Base Station 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. The Worth Data RF system is different from other systems in that our RF Terminal does not constantly “listen” for a data prompt from the host. We decided to use a different approach that would help to eliminate unnecessary radio traffic, conserve battery power, reduce the size of the Terminal, and greatly simplify the operation.

Here is how it works:

Each RF Terminal has a unique Terminal ID. When the RF Terminal powers up, it asks if you want to SIGN ON? Pressing YES at the SIGN ON? prompt causes the RF Terminal to transmit it’s Terminal ID and a byte of data indicating to the Base Station that it wants to sign on to the system.

When you press YES to the SIGN ON prompt on the RF Terminal, the Terminal will display the following message:

WAITING ON BASE TO ACKNOWLEDGE

This message is normal when first establishing communication and may occur occasionally during normal operation.

When the Base Station receives a SIGN ON message from a RF Terminal, the Base Station transmits the SIGN ON information to the host computer. The host computer application can then do one of two things:

•If it has something for the Terminal to do, it can send a prompt to the Base, which in turn transmits it 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 Base Station.

•If the host program does nothing within an allotted time, the Terminal displays the message:

WAITING ON HOST PROMPT
