•
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 J ; 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.
•
Settings 8 and 9 enable and disable the reading of UPC-E1 codes. See
the UPC/EAN setup parameter for more information.
2 of 5 Length
Default setting 06
Valid entries 00-98
To read variable length 2 of 5 codes (temporarily ONLY!) 00
•
2 of 5 codes are so susceptible to partial misreads that only one length
of code should be read, and that should be checked by the TriCoder.
•
The default setting of 06 causes the TriCoder to read only 2 of 5 codes
that are 6 digits in length. To set the TriCoder to read a different
length, scan any two digit number from the bar pad table. For example,
to change the TriCoder 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.
•
If you have to read variable length Interleaved 2 of 5 codes, specify a 2
of 5 length of
00 , however, you will want to use other checking features
(Data ID, etc.) when creating a program for data collection. 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.
