Communication from terminal program - E1.20 RDM (Remote Device Management) Protocol Forums

Nelly · September 15th, 2017

Hello there

I have bought a USB to RS-485 converter so I am able to communicate with my LED driver (eldoLED POWERdrive 562/S) which supports DMX and RDM(only addressing). I have now downloaded a terminal program which I can transmit and recieve data with, but I don't know what the driver will react on. Do someone have any idea what I could transmit to the driver so the light will change or something like that?

Not sure which USB interface you are using, but you will really need an app that works with it and supports RDM functionality. Are you using a proper USB/DMX interface or just a just a generic USB/485 interface? The latter probably won't work as DMX has very specific timings and baud rate that must be supported.

Im using a generic USB/485. I searched for a RDM/DMX controller program to test the connection to the driver and it worked. But the terminal program won't work, maybe because of the specific timings and baud rate you are talking about. Thanks for the answer! I have another question though.

If I want to programme a RDM/DMX controller myself with very basic requirements like turning up/down the light and send a request message for info to the driver. Do you have any acknowledged library you could recommend that works with C++, C# or something else?

I understand that some versions of the eldoLEDPOWERdrive 562/S firmware are not 100% compliant with the RDM standard, which can upset some controllers.

Aldso note that RDM is for configuration. To turn the light on you need to send DMX512 slot values.
