Enttec RDM USB Pro not decoding get response - E1.20 RDM (Remote Device Management) Protocol Forums

ericthegeek · December 9th, 2013

I can't speak for Enttec, but in general there's a tradeoff between how much intelligence you put in the peripheral (USB to DMX adapter), and how much you require from the host software. In this case it appears they put address filtering in the peripheral. With something like a USB protocol it assumes your software is doing everything correctly and doesn't offer a lot of error handling.

When I glanced over their RDM Library for Windows it appears to be a bit more foolproof. You pass your PID and payload to the library, and it takes care of building up the packet around it.

One of Enttec's people posts here occasionally, he may have an official answer.

If you need this specific behavior to emulate another controller, may be worth dropping Enttec a note. Also, there are other USB to DMX+RDM peripherals available that may offer what you need.

If you haven't found them already, consider attending one of the RDM Plugfests. They're perfect for product developers.
