D-15 Entering ASCII Characters as Hex
Values
Commands that require ASCII text fields, such as Preamble and Postamble commands, can be sent
to the reader as hex values.
To enter ASCII fields as hex values (00 to FF), add a lower-case h directly after the command’s K
number, and then enter the hex value that corresponds with the desired ASCII character.
Example:
Consider the Postamble command:
Imagine that your application requires the ASCII character > to be the postamble in your symbol
decode output.
The ASCII characters <, >, and
, can only be entered as hex values. So, to make > the postamble in
your symbol decode output, enter the Postamble command as follows:
<K142h,,3E>
Note that the “status” field contains only a
, . This is because the only field that is being changed is the
“postamble character(s)” field. (See Serial Configuration Command Conventions for a more detailed
explanation of this command shortcut.)
Serial Cmd Format: <Knnnh,00-FF>
Serial Cmd: <K142,status,postamble character(s)>
