It's true.

I went through the wiring of the c1auxex crate today to disentangle the pin assignments. The full detail can be found in attachment #1, #2 has less detail but is more eye candy. The red flagged channels are now marked for removal at the next opportunity. This will free up DAQ channels as follows:

TYPE Total Available now Available after
ADC 24 2 14
DAC 16 8 12
BIO sinking 16 7 7
BIO sourcing 8 8 8

This should be enough for temperature sensing, NPRO diagnostics, and even eventual remote PDH control with new servo boxes.
