3–16 Configuring the Scanner
According to AIM standards, a UPC with supplemental bar code is
transmitted in one of the following formats:
]E0 (UPC chars) (terminator) ]E2 (supplemental) (terminator) or
]E2 (supplemental) (terminator) ]E0 (UPC chars) (terminator)
In the 2755-HDG-4, however, this format is changed to:
]E0 (UPC chars) ]E2 (supplemental)
Therefore, a UPC with two supplemental characters, 01234567890510,
will be transmitted as a 21-character string ]E00012345678905]E110.
