Note: When GENLOCK is selected as the sensor shutter reference, shutter start timing (SHUTTER

PHASE) may still be adjusted. HD-SDI monitor outputs will automatically sync to the external

GENLOCK signal as soon as it is detected, there is no need to enable this function. Sensor shutter

sync to GENLOCK is only supported with HD-SDI.

PIN SIGNAL DESCRIPTION

1 GROUND Common Ground

2 SS/GPI Shutter Sync / GPI Trigger Input

3 TIMECODE SMPTE unbalanced timecode Input

4 GENLOCK RS170A Tri-Level Sync Input

NOTE: The Camera Brain’s Shutter Sync / GPI Trigger uses a 3.3 V Schmitt trigger (5 V tolerant). It

is not a switch closure circuit. Therefore, it requires current supplied by the trigger source. Both

edges of the input signal may be used as a trigger.

For example, when GPI trigger is used for Record Start / Stop.

• Start Record: On Ground to 3.3 V transition

• During Record: Hold at 3.3 V

• Stop Record: On 3.3 V to Ground transition

• During Stop: Hold at Ground
