So, we are trying to use our old console as an rfu so that we can do control from backstage. The rfu on an express is 6 pin and obviously the dmx is 5 pin so the question is "is there an adapter that we can make/purchase and if not what is the best way to go about doing this?".TIAMatt Barber
Three ways to accomplish what you desire (in order of expense):
Unplug the DMX cable that goes from the Express' DMX1 out port to the wall (to dimmers), and plug in a long DMX cable from your old console. Obviously this will take control away from the Express.
Almost the same as above, but use an "A/B Switch" (such as the Fleenor SW1)which eliminates the replugging.
Use a DMX merger (such as the Fleenor 221E) and both consoles will talk to the dimmers simultaneously, on an HTP (biggest guy wins) basis. What happens on one console will not affect what happens on the other.
