General Operations

All information about piezo and flip mount status is in ThorLabs Kinesis app. Search for it in Windows start menu.

Code is in VSCode. To open folder, go to "C:\Users\moss-ladmin\MOSS".

The file you want to run is called pulses.py.

Use command-line parameters as shown in observing log above, with format " python pulses.py -n num_pulses -d duty_cycle -f frequency".

Piezo Control

Odd Piezos on Kinesis are movement in azimuth; even are movement in elevation, as shown in image below on non-piezo stage.

Flip Mount Control

Position 2 is with ND filters out of beam. Position 1 has them in the beam.

Potential Errors and Fixes

You get an "unable to connect to LabJack"/LJME not found error when you try to send in a pulse.

→ Restart the computer. There is a cable in the LabJack that will factory reset the device each time it loses power.

You can't remote in to the computer.

→ Make sure you are on summit wifi. 

→ Make sure you are using the proper login and that it is configured to log in automatically.

You get a "USB device asking for more power than port can supply" error.

→ Restart the computer.
