We soldered together two DB37 adapters to set the gains of the photodiode amplifiers manually. During testing in the corner we noticed that channel 4 was busted. We rewired PD 4 onto channel 3 and left PD 3 out. The transimpedance gain setting in the corner is 20 kOhm and 200 kOhm in the end. Each adapter uses 2 toggle swirtches, labeled D0 and D1, to set the gain:

• D0 and D1 open: 20 kOhm
• D0 closed, D1 open: 200 kOhm
• D0 and D1 closed: 2 MOhm
• D0 open, D1 closed: 20 MOhm
