Emergency Stop Interlocks

[smokeAndMirrors]

Argh! I'm adding more projectors to my show, and now need to support multiple emergency stops. I've seen a 3-way interlock adapter, are there any 4-ways for sale? And where to get longer cables (50m+)?

You could rewire your projectors internally so they use pins 4/17 of the ILDA cable. Then no extra cables

"No extra cables" sounds good! Where does the Big Red Button attach to?

Inline with the ILDA cable. Or if you use a stage box then you have a single eStop and a multi pole relay to open the interlock loop.

Hmm I am closer to "stage box" but the parts are not in a box (gaffered to the top of a flight case!) so this doesn't sound so practical.

Might just build myself a 4-way DB9 breakout. Can't seem to find long DB9 cables though (so I'll have to make one of those, too).
