Disappearing Key Assignments

[cdmackay]

thanks Ian, Sylvain!

I have one too, but only used it once, and couldn't make sense of it, partly I think because I used it on something that wasn't working properly, so couldn't calibrate my head to it

So neither lights means 0V, i.e. not connected/not in use?

My other confusion was whether the left bank of 8 lights was 4 pairs of [0,1] for signals 1–4, or the 0 indicators for all 8 signals. Sounds like it's the former.

I'll get mine out and try it again. Thanks!
