CTRL (RS232 CONTROL)

A 4-pin LEMO connector supports RS232 remote control for 3D camera communication, 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 function for the General Purpose Output is Record Tally.
