Ctrl (Rs232 Control) - Red Epic EPIC-M Operation Manual

RED EPIC OPERATION GUIDE

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.
PIN SIGNAL
1 GROUND
2 232 RX
3 SS/GPO
4 232 TX
NOTE: When active, the GPO tally presents 3.3V @ 0.04 Amps maximum between pins 1 and 3. When used
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.
NOTE: A pre-fabricated CTRL interface cable is available from RED Digital Cinema.
