Worth Data 802 RF user manual Length, MSI and Plessey

•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 (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.
