Vixen DMD-3 controller with GPUSB questions
Posted: Mon Sep 17, 2018 2:01 pm
Hi,
I am working on adding the cable to Vixen DMD-3 controller to connect to a GPUSB.
I'm a bit confused about a couple of things (haven't done anything yet)
1. I bought a GPUSB-AH (Active High) based on previous reading about the DD-1 but not sure if that is correct for the DMD-3.
2. If I'm only using the GPUSB do I need relays, or can I just wire the RJ12 cable directly to the push button pins?
3. Which connections to wire to? The picture in the documentation (eq_mod.pdf) is similar but not exactly the same.

Attached are photos of the controller and board.
Any 'guidance' would be appreciated.
Thanks,
David
