Does anyone have information on how to hook up eta 1252 dimmer packs to a mc12cm controller. the controller has the normal eta ultraplex and dmx512 outputs as well as midi connections however the dimmer packs have a connector I have not seen before on a dimmer pack! it is a screw in din also known as a SD-60LP is this ultraplex?? Since ETA is long gone...... any help would be very much appreciated!!!
