Pioneer PDP-427XA and NAD T763

I would like know if one or both of these devices (Pioneer PDP-427XA and NAD T763) are supported by Roomie via RS232.

If they are not directly supported, is it possible to add a custom RS232 device with feedback?

The Roomie and iTach solution is exactly what I am looking for, but I would like to know what level of compatibility I can expect before buying in.

Thanks in advance.

We do have a custom device DDK if you’d like to add command sets for those devices over serial:
