Mitch, Jim
We got a window this afternoon to try installing L4Cs in HAM2. We just did the horizontal L4Cs and cables, because those were the most difficult, but least in the way parts. The H3 L4C in particular was very difficult, I had to go in and work under the SPI ISIJ telescope, laying on my stomach in the beam tube, while trying not to kick the modecleaner baffle out of place. Also, the gap between bottom edge of St1 and the bottom of the nozzle to the modecleaner tube is just slightly narrower than my elbow, so I could fit my arm in there, but was never sure it would come back out easily. Anyway, the hard part is done, we will finish the verticals next week sometime. I also need to get back with Fil about running the in air cables to the feed thrus. We should have the in rack electronics next week some time as well, so I will try to get the adc wiring in the model set up before interface chassis arrives.
For ADC assignment, see the green boxes on the redline posted to D1101576:
REDLINE_HAM23_Wiring_SPI_CRS_L4C_AA_ASSIGNMENT (P3)
If the Duotone channel is set on ADC0 CH31 as shown in this wiring diagram, we will have to skip the last db9 of the left AA shown on the picture above (or loose the Pod Pressure signal).
In summary, here is the proposal:
ADC0 CH24-25: L4C H1,V1 Signals
ADC0 CH26-27: L4C H1,V1 Diff Pressure/Pressure
ADC1 CH24-25 L4C H2,V2 Signals
ADC1 CH26-27: L4C H2,V2 Diff Pressure/Pressure
ADC1 CH28-29: L4C H3,V3 Signals
ADC1 CH30-31: L4C H3,V3 Diff Pressure/Pressure
