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

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
