SUPPORTED_PARAMETER_ENHANCED - E1.20 RDM (Remote Device Management) Protocol Forums

Hello,
I need an explanation about SubDevices.
Let's assume that I have 2 non_identical SubDevices.
The first one supports 2 PIDs
The second one also supports 2 PIDs but different from the previous one.

If I send a GET SUPPORTED PARAMETERS ENHANCED to the first one,
shall it respond only with its own 2 PIDs or the answer have to contain all
four PIDs?

Thank you

With SUPPORTED PARAMETERS ENHANCED if you have the Non-Identical Sub-Device Flag set then each sub-device queried can return a separate list of PIDs and they would only be the list of PIDs supported by that particular sub-device.
