MS851B User’s Manual
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 scanner, 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.
