Bar Code Type
The Bar Code Type parameter selects the bar code type for entering its associated label
identifier information. After entering a Bar Code Type, enter the Common Byte and Unique
Identifier. This procedure repeats until the label identifiers are specified for each bar code type.
Scan the
Hex 0 through Hex 9 tag to enter the appropriate Bar Code Type.
Note:
UPC Version D is always disabled.
Common Byte
The Common Byte parameter selects which common bytes, if any, to add to the bar code data
message. Each entry is unique to the previously specified Bar Code Type. Scan the
Hex 0 tag
for no Common Bytes, the Hex 1 tag for Common Byte 1, the Hex 2 tag for Common Byte 2,
the Hex 3 tag for both Common Bytes, or the Hex 4 tag for AIM ID on GS1 DataBar.
Unique Identifier
The Unique Identifier parameter permits the specification of the data sent to the host terminal
in the Unique Identifier field. Each entry is unique to the previously specified Bar Code Type.
Enter this data as two (2) Hex characters using recommended values of 20 to 7E (Refer to the
“
ASCII Code Chart” section in chapter 5).
Note:
If the same characters are used as in the Terminator Byte, the message may terminate
too soon.
