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 SE955, 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, ]E00012345678905]E110.

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, Parameter Menus for the L1 and L2

parameter numbers.

Depending on the selected option, the scan engine decodes:

• One discrete length bar code

• Two discrete length bar codes

• Bar codes within a range of lengths within the scan engine capability

• Any length of bar codes within the scan engine capability.

Table A-3 lists the requirements for each option.
