Serial Programming Command Examples
Command Function
STX ESC PC ETX Enable Interleaved 2 of 5 with check digit.
STX ESC PD12 ETX Set Interleaved 2 of 5 minimum length to 12.

STX ESC LB6162364 ETX 1 Set Postamble to ’abcd’.
Each ASCII character is encoded as two hexadecimal characters. For example:
1=31, 2=32, 3=33, 4=34 and a=61, b=62, c=63, d=64. 1
The scanner firmware makes no attempt to resolve
conflicts between serial programming commands and
manually scanned menu labels. If you plan to scan
menu labels, do not attempt serial programming, and
vice versa.
Serial commands are given priority over pending
menu labels. For example, if you scan the menu label
PD (which sets a minimum length for Interleaved 2 of
5 labels) and the scanner is waiting for a two-digit
minimum length code when a serial command is
issued, the serial command is acted upon and the
pending manual command (PD – Set Interleaved 2 of 5
Minimum Length) is ignored.
