Performed diode check measurements at the air-side 25 pin D-sub associated with ITMY (BSC8) scattered light photodetectors.  Flange number was F1, subflange 3.  There are two 25 pin D-sub connectors, which we designated "TOP" and "BOTTOM".  We still don't know which set of photodiodes are associated with H1 and H2, but the measurements are complete.

ALL MEASUREMENTS ON AIRSIDE PINS WITH FLUKE DVM ON DIODE TEST

TOP D-sub, PD1, pin 1 = anode, pin 2 = cathode, diode voltage = 0.412V
TOP D-sub, PD2, pin 4 = anode, pin 5 = cathode, diode voltage = OPEN CIRCUIT
TOP D-sub, PD3, pin 7 = anode, pin 8 = cathode, diode voltage = 0.421V
TOP D-sub, PD4, pin 10 = anode, pin 11 = cathode, diode voltage = 0.420V
Verified pin 13 is open circuit to vacuum tank indicating shield is not shorted to ground internal to the vacuum system

BOTTOM D-sub, PD1, pin 1 = anode, pin 2 = cathode, diode voltage = 0.423V
BOTTOM D-sub, PD2, pin 4 = anode, pin 5 = cathode, diode voltage = 0.423V
BOTTOM D-sub, PD3, pin 7 = anode, pin 8 = cathode, diode voltage = 0.424V
BOTTOM D-sub, PD4, pin 10 = anode, pin 11 = cathode, diode voltage = 0.424V
Verified pin 13 is open circuit to vacuum tank indicating shield is not shorted to ground internal to the vacuum system

For all pins on top and bottom, we checked every permutation to verify there are no unintended pin-to-pin shorts in the vacuum system
