Welcome to the forums. Which RDM Test Platform are you using? There's a couple out there so knowing that will help.

The Discovery Command Class is 0x10. This is detailed in Table A-1. The PID values are in Table A-3 in the document.

What are you are probably seeing is that Section 6.3.4 stipulates that a NACK is only sent for unknown GET_COMMAND and SET_COMMAND requests.

If you see a Command Class for DISCOVERY_COMMAND then you should not send a NACK.
