![2-132 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.

![7-3Record/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](https://usermanual.wiki/Worthdata/LT802/User-Guide-599054-Page-52.png)
![7-4To 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.](https://usermanual.wiki/Worthdata/LT802/User-Guide-599054-Page-53.png)

![F-1 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. 12345](https://usermanual.wiki/Worthdata/LT802/User-Guide-599054-Page-75.png)
![F-2Scanning 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 Stop Code 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.
