[sdiy] Mini-Din cable woes

[Nathan Trites]

Hi Joel,

On this page the Connector/Mixer layout makes it look like they're pretty
straight forward... just triggers + ground, but doesn't offer any insight
to how they're actually wired to the DIN jacks.

If there's another PCB for the Mini DIN's it should be fairly
straightforward to trace from the mixer PCB to those and see whats going
on. Photos of any DIN jack PCB and wiring inside the unit would be helpful,
as well as seeing how you've wired the TRS jacks.

Is there any way to confirm the voices all work without the trigger cable?
