Installation

Components

The 802 Terminal is 802.11b compatible operating between 2399.5 MHz and 2474.5 MHz 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 Manual.

• 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.

• 802 Utilities CD ROM – demo programs, Active X development

software, test program, 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 Tips

1. Be sure all Access Points and Terminals have the same SSID and WEP Key, (if Encryption is used). Terminals are shipped with a SSID of

WORTH DATA.

2. Start with one Terminal. Get everything working with the single terminal and then add other terminals, being certain that all terminals have unique IP Device Address.

3. Use the 802 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

1-1

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 SHIFT is on by the cursor on the display. When upper case alpha 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 rechargeable batteries (L01) from Worth Data along with a 9v recharging Power Supply that recharges the batteries completely within 2 hours. When recharging options (batteries or Power Supply) 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 non-rechargeable alkalines with no recharging options set in the Terminal. However, you may change the battery type yourself. Using NIMH or alkaline batteries, you should get 24 hours of operation (assuming 1 transaction every 8 seconds).

If you did not order the rechargeable batteries and you change to rechargeables, you must change the Terminal's Setup to Batteries 1 to allow recharging. If you want to charge the batteries without having to remove them from the Terminal, you must use the Worth Data 9v power supply.

You can safely use alkaline batteries in a terminal set for recharging,

providing you don’t plug a power supply into the terminal. Recharging Alkaline batteries may cause the batteries to explode and leak battery acid throughout the RF Terminal. Battery acid damage is not covered by the

Worth Data warranty because it not deemed to be “normal use”. If you are using alkaline batteries (either regular or rechargeables) and

have selected the Rechargeables setting in the Battery setup parameter (See Chapter 2; RF System Setup), the RF Terminal will generate the following error message:

Alkaline Batteries Detected, Rechargeables Are Specified Do Not Recharge

1-2

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 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. Press the STATUS key to display the remaining battery life of the AA batteries (as well as the date, time and other information) as follows:

mm/dd/yy hh:mm alkBAT-zz% ServerIP=nnn.nnn.nnn.nnn DeviceIP=nnn.nnn.nnn.nnn Ch:=n SSID=xxxxxxxxxxxx WEP=128 Signal=nn%

setup

• 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, if 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 first 12 characters of the up to

32 character network name.

• WEP=128 or 64 or NO shows how the Device is configured

with an encryption key.

1-3

• Signal=nn% shows the signal strength from the best Access

Point with the same SSID (if already SIGNED ON).

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 NiMH 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 F15 9V power adapter into the RF Terminal.

3. The firmware in the terminal then checks the level of charge in the 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 three modes of operation for the R/F Terminal:

DEVICE SIGN ON Signs R/F Terminal on for two-way

communication with host.

SETUP MODE Accesses Setup parameters for Terminal and Base. SITE SURVEY Allows you to survey the Access Points strength

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

802 TERMINAL 1XWFUnnn ServerIP=nnn.nnn.nnn.nnn DeviceIP=nnn.nnn.nnn.nnn Ch:=n SSID=xxxxxxxxxxxx WEP=128 Rnn HIT ANY KEY

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

• The first line on the screen, 802 TERMINAL WFUnnn, 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 if it

is determined by a DHCP Server, shows 0.0.0.0.

• Ch:=nn shows the channel to start using, (the channel of the most

frequently used Access Point, 01-11).

• SSID=xxxxxxxxxxxx refers to the first 12 characters of the up

32 ch character network name.

• WEP=128 or 64 or NO shows how the Device is configured

with an encryption key.

• Rnn=the radio firmware version.

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

RF System Setup

RF Terminal Setup

The RF Terminal itself can be configured using the Terminal keypad or by using the bar coded Setup Menu, which is in the back of your manual. Even if you configure the RF Terminal using the keypad, you may need the bar coded Setup Menu to use as a reference. Most users do not need to change anything in the setup. Some parameters are available only by bar code menu and others only by keypad:

Bar Code Menu Only Keypad Only

Reset Server IP

Device IP Starting Channel SSID Subnet Mask WEP Encryption Key Control Keys Only

Automatic Check Back

If you are using the bar coded Setup Menu and are unfamiliar with scanning bar codes, see Appendix M; How to scan a bar code to learn proper scanning technique before you begin scanning the bar codes on the Setup Menu.

RF Terminal Default Settings

This is the default configuration of the RF Terminal as it is shipped from the factory. If you ever need to return the RF Terminal to these default settings, use the bar coded Setup Menu and scan the following bar codes in this sequence:

• START SETUP

• RESET

• END SETUP

Using the bar code RF Terminal Setup Menu

To use the bar coded 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

• 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.

2-2

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 SETUP MODE----------->2 SITE SURVEY----------->3

Press the 2 key to change the configuration of the Terminal Device. At this point, the terminal will ask for a password:

SETUP MODE PASSWORD?_

Enter WDTRI on the keypad. The next item allows you to choose which item to configure:

R/F Terminal------->1 Voice Operations->2

Press 1 to enter the RF Terminal Setup. Now you are in the RF Terminal Setup Menu and can choose from the

following options:

RF Setup---0 Batteries--4 BarCodes--1 Speaker---5 RS232-------2 Other------6 Date/Time--3 Exit-------F1

At this point, choose which group you want to configure. Most of the RF Terminal setup parameters are accessible from the either the keypad Setup Menu or the bar code Setup Menu. There are only 2 that are available only from the bar code Setup Menu while there are quite a few options that are available only from the keypad Setup.

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 (default) 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 Address

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

Setup

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 255.255.255.0, then

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. To save time, the Terminal Device will try other channels in case the Starting Channel does not immediately find an Access Point.

2-5

Setup

SSID

Default SSID None

User Defined XXXXXXXXXXX

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

name here (up to 32 chs). The default setting is NONE. You will need to change it in order to sign on to your network. The SSID is casesensitive; if you want an SSID with lower case characters, use Shift F2 to go into lower case or you will have to scan the Full ASCII Menu.

WEP Encryption Key

• Here is where you enter the encryption key (WEP). If you want a 64 bit

key, enter the 10 hex number (0-F) string to use. If you want a 128 bit key, enter the 26 hex (0-F) number string to use. Whatever you enter should match the Access Point's WEP key.

Authentication

Open System 0

Shared Key 1

• Before a wireless client device can communicate on a network, it must

authenticate to the access point and the network. You must enter a WEP Encryption key to access the Authentication settings.

Setup

• Open System authentication, which is the default setting, is the

preferred method – it allows any device to authenticate with the access point, but will only allow it to communicate if the WEP keys match.

Setup

• Shared Key is allowed to comply with the IEEE 802.11b standard,

however, because of its security flaws; it is not the recommended type of authentication.

Control Keys Only

No 0

Yes 1

Othe

• 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.

2-6

• 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.

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)

LCD Backlight Display Mode

No 0

Yes 1

Other

The Backlit Display is standard. The default setting is for the LCD Backlight to be ON. As shipped the Backlight Duration is 5 seconds.

Backlight Duration

Always ON 0 Duration in # of seconds

1..2..5..-9

Othe

The Backlight Duration is of no concern unless you have set the LCD Backlight Display to 1 for YES. This setting determines how long the

Backlight Display is on at startup or when triggered by pressing the F2 key. Always ON will create a drain on your batteries and you can expect shorter battery life. The default setting is 5 seconds.

Skip Opening Screens

No 0

Go to Device SIGN ON 1

Setup

• Many users want to skip the opening screens and go directly to SIGN

ON communication once their programs are fully operational. Selecting 1 will automatically take the operator to the DEVICE SIGN ON and into your application program, skipping the screen shown below:

DEVICE SIGN ON ------>1 SETUP MODE------------>2 SITE SURVEY------------>3

2-7

If you have skipped the above screen and want to get to it, simply the press the F1 key.

If your skip the opening screen and you want to check the settings of the Terminal without having to reset this parameter, just press the Status Key and the terminal will display six lines as follows:

mm/dd/yy hh:mm alkBAT-zz% ServerIP=nnn.nnn.nnn.nnn DeviceIP=nnn.nnn.nnn.nnn Ch:=n SSID=xxxxxxxxxxxx WEP=128 Signal=nn%

alk - when Alkaline batteries are specified in Battery setup rch- when NiMH batteries specified in Battery

setup

zz=percent or battery life left in numbers i.e. 99, 50, 23

• 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 if 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 first 12 characters of the up to

32 character network name.

• WEP=128 or 64 or NO shows how the Device is configured

with an encryption key.

• Strength=nn% shows the signal strength from the best Access

Point with the same SSID, (if already SIGNED ON).

Press the STATUS key again to resume processing.

Speaker and Headphone Volume Controls

Speaker

By selecting Speaker in the keyboard Setup Mode, you get to the options to control the Speaker/Beeper and Headphone volumes. If you are using headphones, you will want set the Speaker volume to 0 to conserve batteries. Volume settings possible are 0-9.

The prompt for Speaker Volume is:

SPEAKER VOLUME Enter 0-9 for Volume Control Current Value is: 5

2-8

The prompt for Headphone Volume is:

HEADPHONE VOLUME Enter 0-9 for Volume Control Current Value is: 5

Automatic Check Back

Other

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 00-99. 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). This parameter's prompt is:

AUTOMATIC CHECK BACK Key 00-99. Current Value: 00

Codes

• 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

2-9

characters can be useful if you need to differentiate between data that

comes from a bar code versus data coming from the keypad.

• Enabling use of the Mod 43 check character requires that the last

character of your bar code conform to the Mod 43 check character specifications. See Appendix E; Code 39 for more information. Enable transmission (A) will send the check digit data along with the rest of the bar code data to your computer. To use A, you must also be using 8.

• 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.

• 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.

• 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 (prior to January

2-10

2006) 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 parameter. To enable UPC-E1 reading, set the 2 of 5 Code parameter 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

(USA county code) to the UPC-A data. This setting is found in the

Laser Options parameter. To transmit in EAN-13 format, set the Laser Options parameter to F. To return to the default (UPC-A transmitted in original format) set it to E.

• 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.

code used for the storage of computer data tapes. Enabling the tape label

code (C) does not disable reading of Code 128 or Code 39 bar codes.

• Bar Code ID’s are characters assigned to each bar code type to identify

that particular type of code. These Bar Code IDs can be output as a prefix to the bar code data to identify what type of bar code you are using. The Bar Code ID’s are assigned as follows:

specifications for the 2 of 5 check digit calculation. See Appendix I; 2 of 5 Code for more information.

• Transmission of the check digit (5) requires the use of setting 2 and will

transmit the check digit along with the bar code data to the computer.

• Setting B pertains to the decoding algorithms used by the RF Terminal

when using a Laser Scanner. In most cases, this should be left at the default B setting.

• If scanning VINs (Code 39) through windshields with a laser scanner,

(applies to the LZ400 only) try setting this parameter to C or D. Try D first. If you get substitutions, try C.

2 of 5 Length

Default setting 06

Valid entries 00-98 To read variable length 2 of 5 codes 00

• 2 of 5 is so susceptible to misreads that the RF Terminal adds an additional

safeguard - it can be configured to look for fixed-length data only.

• The default setting of 06 causes the RF Terminal to read only 2 of 5

codes that are 6 digits in length. To set the RF Terminal to read a different length, scan any two-digit number from the bar pad table. For example, to change the RF Terminal to accept an 8-digit bar code, scan 0 then 8 from the bar pad table. 2 of 5 code must always be an even number of digits so the length setting must always be an even number.

• Reading variable length I 2of5 or 2 of 5 codes is to be avoided if at all

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.

Set Date

Time

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.

Voice Message Partitions

Other

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.

• Double Decode is there to minimize the possibility of misreads when

scanning very poor quality bar codes. This option forces the RF Terminal to keep reading until it gets two results that are identical. This "double scan checking" takes longer but will minimize misreads since it must get the same result twice before considering it a "good" read.

• 4-second laser beam increases the amount of time the laser beam is

activated, giving the laser more time to try and read a code. This option is useful for trying to read poor quality code. Using the 4second laser beam with long range lasers give the operator more time to aim the laser properly at a distant bar code (usually using the "marker" beam). The default beam time is 2 seconds.

Aiming Dot Duration

Other

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

in 1/10

second increments; i.e., 20 would be two seconds.

Reset

While in Setup Mode, DO NOT scan the RESET bar code unless you want to set all of the RF Terminal setup parameters back to the factory default settings. Scanning RESET will erase all changes you have made.

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 RF Terminal system consists of three components – Host Server, Access Points and RF Terminal. The Access Points are connected to the Host Server by Ethernet wiring. The RF Terminal "signs in" by establishing communication with a Server Program (located on the Host Server) through an Access Point. After the RF Terminal "signs in", the Server Program can send a

prompt to the terminal with the ActiveX program interface provided by Worth Data. The application running on the Host Server sends a data prompt to the RF Terminal device to the Access Point (using the Ethernet wiring), 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 Host Server. The application on the Host

Server 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 and WEP Key using the Channel Number in its configuration as the starting channel.

2. If the terminal is configured to obtain its IP address from a DHCP Server, it requests an IP address from a DHCP Server. If it requests an IP address, the terminal will display:

Looking for DHCP Server, Please Wait

3. If the terminal does not have a fixed Server IP address configured, it does a search for an Application Server. While is searches for an Application Server, the terminal will display:

Looking for App Server, Please Wait

4. Now the RF Terminal 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.

3-1

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

1. 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 2 seconds, the Terminal displays the message:

WAITING FOR PROMPT FROM HOST COMPUTER

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 within 2 seconds, the Terminal Device displays

WAITING FOR PROMPT FROM HOST COMPUTER

until the prompt is received. If the Terminal gets no response after 3 transmissions, it will perform an

Access Point scan. If it fails to get a good signal from an Access Point with matching SSID and WEP Key, it will display the message:

TERMINAL OUT OF RANGE PRESS ANY KEY TO RETRY_

You might walk closer to an Access Point or you might simply hold the terminal up high over your head. When you have repositioned the terminal, pressing a key on the Terminal starts the transmission process over again.

If the Access Point scan finds a satisfactory Access Point, the Terminal will display the message:

SERVER NOT AVAILABLE HIT ANY KEY_

This tells you that the Application Server host program is not running. If you press a key, you will be transferred to the mode menu where you can chose to Sign On again.

3-2

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 to a slow operator or even locate a lost terminal with beeping. You can do this using the "Automatic Check Back" option. You set a predetermined interval (in increments of 5 seconds) of when you want the terminal to send back a message "do you have a change for me?" If there is no change, you simply resend the original prompt; if there is a change, you send the changed prompt. (See Chapter 2

, Automatic Check Back).
