3.3 Hex Dump Mode
The hex dump mode is a useful tool for diagnosing problems, including communication and DPL

syntax errors, allowing a comparison of input strings (sent by host) to output data (received by printer).
To decode this information, the
Class Series Programmer’s Manual is an essential reference. This output
can be used for debugging the label format. And, by repeatedly sending a format, this mode can uncover
handshaking problems (if they exist). Handshaking problems are identified by sections of missing data in
the character string.
To begin, go to the Diagnostics menu and enable Hex Dump Mode; see the Operator’s Manual for details.
Exit the menu, save changes and returning to the ‘READY’ mode. Now all data sent to the printer will
now be output in hexadecimal code, along with the printable ASCII equivalents.
The figure below is a sample Hex Dump Label. After sending a label format to the printer, the hex code
output will be immediate. As a final note, many of today’s software programs use bit mapping to
construct the label, making diagnosis difficult. Contact Datamax-O’Neil
Technical Support with any
questions.

Note: To exit the hex dump mode, re-enter the Diagnostics menu / Hex Dump Mode and select ‘Disable’. Exit
the menu, save changes and return to the ‘READY’ mode.
