Subdevice labelling question - E1.20 RDM (Remote Device Management) Protocol Forums

ericthegeek · August 1st, 2013

I have seen a number of responders that support GET for DEVICE_LABEL on Sub-Devices, but that don't allow you to SET it.

For example, the Root has a Label that can be both GET and SET, but each sub-device has a Label like "Channel 1" that can only bet read with GET. When you try to SET the Sub-Devices's label it will "NACK Unsupported Command Class"

Hi

I have added the support for DEVICE_LABEL on GET with the subdevices.

I am interested in what Eric wrote in that he has seen the labels being "Channel 1" etc. I have this but I have used the DEVICE_MODEL_DESCRIPTION for that purpose.

I now wonder if I should change again and move the "Sub1" etc to the subedevice label rather than the model description and merge it with the root label?

More concerning is that another manufacturer does not support subdevices at all and now one of our users is unhappy that he can't use our unit on their controller :-(

To fix it from our side, I would have to redo the complete RDM implementation and not use subdevices at all. I have no idea how to do that as we need individual control of the parameters of each channel ie DMX personalities etc.

Best regards
Bernt
