I've copied this over from Blue Room as there's not much response there.
I am trying to control a JEM smoker using the auxiliary function of a new Jester 24/48. I have very little experience of DMX. The setup is this - the Jester is connected to a new Demux which has four analogue DIN cables to four analogue Betapacks. This is what I have done so far: The smoker is working fine using the test button Jester DMX patch is ex-factory, I.e. ch 1-24 = DMX 1 -24 The Zero88 Demux is with ex-factory settings. Connected the smoker to DMX Out on the Demux In Super User, I have gone into Aux setup, pressed Preset A Flash Button on Channel 24, and set it as an Aux Flash. On the JEM DMX controller I have set the dip switch to 000110000 (=24) Back in Run mode on the Jester, I have tried holding down <Shift> and Flash button 24 and nothing happens...
UPDATE: Got the smoker working fine with the slider which of course gives smoke volume control. Button still doesn't work. I don't think I understand this Auxiliary business. Seems pointless - and doesn't work anyway.
