- ctalab machine
  - # host odo
    odo.nevis.columbia.edu is an alias for ctalab.nevis.columbia.edu.
    ctalab.nevis.columbia.edu has address 10.44.2.10
  - Started ssh server following direction on this page:

  - NOT WORKING CURRENTLY
Switched capacitors on test board to power Hamamatsu SiPM (Nancy)
- Did this to accommodate higher bias voltage needed
- C1, C3, C4: replace with 100nF, 100V (1206 package)
- C5, C6, C7: replace with 2.2uF, 100V (1206 package)

Tried to find the network card for the UPS
- Not located upstairs in the supply room as was initially thought
- Found one that looked like it could be it in Bill's office, but not sure how it could've gotten there with Bill absent
Programmed the Aim TTi EL302P -USB PSU
- added as a class of the dcps python package, new class called 'AimTTiEL302P"
- can find the code at /home/ctalab/anaconda3/envs/cta/lib/python3.8/site-packages/dcps/AimTTiEL302P.py
  - So far implemented commands to do:
    - Write voltage
    - Write current
    - Read voltage
    - Read current
    - Measure voltage
    - Measure current
    - Turning output on/off
    - Checking if output is on
  - Start-up code is:
    - from dcps import AimTTiEL302P
    - aim = AimTTiEL302P ('ASRL/dev/ttyACM0::INSTR')
    - aim.open()
  - and then use the `aim` object to do all the commands
- Still need to implement commands for
  - switching between local/remote (this isn't an option for the model we have)
