Ctrl (Rs232 Control) - Red Epic Epic-X Operation Manual

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.

NOTE: When active, the GPO tally presents 3.3V @ 0.04 Amps maximum between pins 1 and 3.
When used as Sync Out, the signal is rising edge pulse at start of exposure. As a Tally, it is rising
edge at start of record, falling edge at end of record.
NOTE: A pre-fabricated CTRL interface cable is available from RED Digital Cinema.
