S

 – Set Source of Shutter Trigger

NOTICE     

External shutter triggering means that a 5VDC signal on the 50-ohm 

BNC connector on the main CARV II unit opens the shutter. 0VDC closes the 
shutter. Internal triggering comes from the touch screen, either manually or 
serially.

F

 – Set Calibration Values of Filter Wheel

Examples

P1<CR>

 

J

 

P1<CR>

The prism is now in the light path (light path directed to the 
binocs).
