ADC channels (1-16):

adc_1   U24 pin 1   Cavity  power        299 mV  <-> 30.0 kW on front panel
adc_2   U24 pin 2   Forward power        299 mV  <-> 30.0 kW on front panel
adc_3   U24 pin 3   Reverse power        299 mV  <-> 30.0 kW on front panel
adc_4   U24 pin 4   Reverse Trip status  98-105=OK   4095=trip
adc_5   U24 pin 5   Forward Trip status  98-105=OK   4095=trip
adc_6   U24 pin 6   Phase monitor        Untested
adc_7   U24 pin 7   RF Interlock         111=fail    3562=OK
adc_8   U24 pin 8   Cavity  Trip status  98-105=OK   4095=trip

Channels 1, 2, 3 are calibrated with -1.1V on back panel J11, J10, J9, resp.
Counterclockwise on the back panel "PWR TRIP LEVEL" pots _increases_ the
trip level, i.e., makes that channel less likely to trip.

Front panel switches, 0 = manual, 3010-3024 = remote:
adc_9   U17 pin 1   Sys Phase
adc_10  U17 pin 2   Amp1 Phase
adc_11  U17 pin 3   Sys Amp
adc_12  U17 pin 4   Amp2 Phase
adc_13  U17 pin 5   Amp1 Amp
adc_14  U17 pin 6   Amp2 Amp
adc_15  U17 pin 7   Cav Phase
adc_16  U17 pin 8   Fwd Signal Phase

(only the TRIP RESET functions have been double-checked;
code 0 -> operate, code 255 -> reset)
