CTRL (RS232 CONTROL)

A 4-pin LEMO connector supports RS232 remote control for stereoscopic camera image capture, and

third party metadata ingest applications.

The shutter Sync Output signal acts as an immediate response hardware tally of a scan. This is useful

for 3D or motion control applications where a slave camera or lighting device needs to be synchronized

to a master camera.

Alternatively, this output pin may be used as a GPO (General Purpose Output) tally, whose function is

programmed in the USER KEYS menu. Default is Record Tally.
