Note: HEX–ASCII and Symbology charts are shown below the Preamble/Postamble
Examples. Special Characters and their explanations are on following (menu) page.
ENTER,
, EXIT
Where: ENTER (Preamble/Postamble) enters programming mode.
selects postamble programming and clears current postamble.
EXIT saves changes and exits programming mode.
2. To frame a message with <STX> (start of transmission) and <ETX> (end of transmission):
ENTER,
, 0, 2,
, 0, 3, EXIT
Where: ENTER (Preamble/Postamble) enters programming mode.
selects preamble programming and clears current preamble.
02 represents the hexadecimal ASCII value for the <STX> character.
selects postamble programming and clears current postamble.
03 represents the hexadecimal ASCII value for the <ETX> character.
EXIT saves changes and exits programming mode.

Code ID
The scanner will transmit the decoded message after every successful bar code read. You
have the option of adding characters before (preamble) and after (postamble) the bar code:
Transmitted data frame –>
Preamble
Postamble
Bar Code Message
Characters for the preamble and postamble are selected by their hexadecimal ASCII
value, up to 8 characters each. In addition, special characters are available for code
identification and for error detection. Programming preamble/postambles is flexible,
allowing creative framing possibilities.
These preamble/postambles apply to all messages regardless of the symbology, and
cannot be assigned for a specific symbology. The special characters for Code ID
will
change to indicate the decoded symbology.
Preamble/Postamble Examples:
1. The postamble defaults to a carriage return plus line feed:
<CR> <LF>
Bar Code Message
If no postamble is desired, scan:
<STX>
First program the preamble, then the postamble, by scanning:
<ETX>
