SE 2223/3223 Scan Engine Integration Guide
According to AIM standards, a UPC with supplemental bar code is transmitted in the
following format:
]E0 (UPC chars) (terminator) ]E2 (supplemental) (terminator)
In the SE 2223, however, the format is changed to:
]E0 (UPC chars) ]E2 (supplemental)
Therefore, a UPC with two supplemental characters, 01234567890510, is transmitted to
the host as a 21-character string,
]E0 0012345678905 ]E1 10.
Setting Code Lengths Via Serial Commands
There are two lengths (L1 and L2) for each variable length code type. See the individual
code types in
Chapter 8 for the L1 and L2 parameter numbers.
Depending on the selected option, the scanner decodes:
• One discrete length bar code
• Two discrete length bar codes
• Bar codes within a range of lengths
• Any length of bar codes.
Table B-4 lists the requirements for each option.
Table A-5. Setting Variable Code Lengths
Code length option L1 value L2 value
One discrete length is decoded Discrete length to decode 00h
Two discrete lengths are decoded Higher length value Lower length value
Lengths within a range are decoded Lower length value Higher length value
Any length bar code is decoded 00h 00h
