ShaneAO WFS Camera Info and Troubleshooting

The ShaneAO WFS camera is a 160x160 SciMeasure Little Joe CCD camera. Communications are via a serial connection through the shaneao software.

The PDF manual has information about the specifications of the camera as well as the serial commands.

To send serial commands to the camera, you first need to initialize the command in the shaneao software: wfs=shaneao.wfs

Here are a few sample commands that are useful. A more comprehensive list of commands that are used for troubleshooting are at user@shimmy in /u/user/observers/lgs/WFSCamInfo/WFSCameraSerialCommands.txt This file also has recorded values for the settings in the camera for reference when troubleshooting.

To query what recalled (saved) mode is currently being used:
wfs.serial('@RCL?')

To read the bias offsets:
wfs.serial('@OAC?')

In some cases the output might be long, or there may be streaming messages filling the screen, so it is useful to write the output to a variable you can print out later. For example:
resp=wfs.serial('@TMP?')
print(resp)

More information about camera settings and configuration files are on shimmy in the /u/user/observers/lgs/WFSCamInfo/ directory.
