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.

as Sync Out, the rising edge of the pulse indicates start of exposure. When used as a Tally, the rising edge
of the pulse indicates start of record, falling edge represents end of record.
