6.2 Hex Dump Mode

Hex Dump mode is a useful diagnostic tool for debugging label formats and hardware problems, as
received host data strings are printed without interpretation by the printer.

To enter Hex Dump mode, press the MENU Key and select DIAGNOSTICS. Go to HEX DUMP
MODE then select ENABLED and press the ENTER Key. Exit the menu, saving your changes.


Afterward, HEX DUMP MODE will be displayed and all received data will be printed in

hexadecimal code (along with the ASCII equivalents); see example below:


To decode the data the Class Series 2 Programmer’s Manual is an essential reference (see the
Accessories CD-ROM). Also, some software programs use bit mapping, which can make analysis

difficult – contact Datamax-O’Neil Technical Support with any questions.


To return normal operating mode, enter DIAGNOSTICS and disable HEX DUMP MODE.
Then, exit the menu, saving your changes.
