The kind people at dsuny sent me the pin out as follows


1R =34vdc + to power controller ?-- yes, ( input). the power is from the light panel.
GND = GROUND
2B = CHANNEL 1. 0-4VDC
-- (out put). this is channel 1. should be 6V. may you sure it is 100% setting?
3G = CHANNEL 2. 0-4VDC
-- (out put). this is channel 2. should be 6V. may you sure it is 100% setting?
4Y = CHANNEL 3. 0-4VDC
-- (out put). this is channel 3. should be 6V. may you sure it is 100% setting?
5W = CHANNEL 4 0-4VDC
-- (out put). this is channel 4. should be 6V. may you sure it is 100% setting?

6F = I DO NOT KNOW WHAT THIS CHANNEL IS ????
--(out put). PWM signal too. this is for Fan signal. (0-6V) 0V is on. 6V is off.
the reason of 2 wires, is because fan is too important and we are worry there is cord damage in case.

Please seems you only need GND, 2B,3G,4Y,5W, 6F. if the profilux has it own power input.
