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.)
