ASCII Character Entry Modifier

Commands that require ASCII text fields, such as Preamble and Postamble commands, can be sent to the Imager as hex value pairs.

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 , can only be entered as hex pairs. 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.
