camera_init [ chan=<n>,... ]	Initialize connection to science cameras. Default is all cameras. Optionally specify one or more channels with comma-separated list, where <n> is one of: U, G, R, I. Examples: camera_init chan=I, camera_init chan=U,G
camera_shutdown	Shut down camera system
camera_set exptime=<t> binspec=<n> binspat=<n>	Configure science camera settings
slit_set width=<n> offset=<n>	Set slit width and offset. Offset is optional
focus_set <chan>=<value>	<chan> is one of U, G, R, I
