Change RDM Parameters of Foundry Dimmer

I recently purchased a Colorsource 20 AV console, Colorsource V Fresnels, Foundry UFD Dimmers, and a Foundry relay panel.

My question is about changing the dimmer curve mode and output response time of the UFD dimmer. It appears that it can only be changed through RDM and I am wondering if I can do this from the Colorsource Console. When I do an RDM discovery, the Fresnels show up as normal but the dimmers only show up as "Unknown device".

Do I have to purchase an ETC Gadget or a response gateway and use Concert to change these parameters or can I use the Colorsource console?

Any help is appreciated!
