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.
Serial Cmd Format: <Knnnh,00-FF>
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:
Serial Cmd:
<K142,status,postamble character(s)>
Imagine that your application requires the ASCII character > to be the postamble in your
symbol decode output.
The ASCII characters <, >, and
postamble in your symbol decode output, enter the Postamble command as follows:
<K142h,,3E>
Note that the "status" field contains only a
changed is the "postamble character(s)" field. (See Serial Configuration Command
Conventions for a more detailed explanation of this command shortcut.)
