I'm all for using old dimmers, but unless you're doing a retro thing, I would dump the board and get something newer.
I have an
ETC Response A32 Out converter that I
plug into my rack of 18
TTI dimmers. That allows me to use any
DMX light board by running just a
DMX cable from my board to the converter back
stage. No nasty multi-wire cable with
Cinch-Jones connectors to deal with.
If you insist on using the old board or enjoy the smell of soldering, I believe the board used one 10 pin CJ
connector for each 6 dimmers and was wired as follows: pins 1
thru 6 control the dimmers, pin 8 is common, and pins 7, 9, 10 are not connected.
