5-42 Chapter 5: Programming
Note:
Refer to the ASCII Code Chart for the Hex Characters; however, values of 20 to
7E are recommended. Do not use the same characters as the Terminator Byte or the
message may terminate too soon. Also, a Common Byte cannot be 00.
If not using a Common Byte, scan any Hex tag twice except Hex 0 or the Terminator
Byte value.
Note: Four (4) tags must be scanned to go to the next parameter.
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.
