I have a DP-415 4 channel DMX Dimming / Switching module being controlled by a ADJ RGBW4c, which is an 8 channel controller. I am linking with wireless DMX transceiver, which is working. I do not understand how to position the DP-415 dip switches to simply control on/off and dimming functions for each of the 4 channels. Can anyone help quickly? Event tonight!!
