Motion Control (MoCo)

NOTE: When using MoCo, set the frame rate to be at least two times (2x) the fastest trigger rate used. When using MoCo, REDCODE is calculated based on fps/2. Therefore, if you are in MoCo mode, and the frame rate is 100.83 fps, the maximum REDCODE is calculated based on a frame rate of 50.415 fps.

NOTE: HDRX is not available when MoCo is enabled.

NOTE: Genlock and timecode can also be used with MoCo.

Motion Control (MoCo) is a form of sensor synchronization used to automate precision camera movements required for special effects and difficult shots. Motion Control uses GPIO signals transmitted using the SYNC (GPI) and CTRL (GPO) ports on the camera or a connected Pro I/O Module or REDCAST Module.

For more information on GPIO connections, go to Input/Output Connectors.

Set Up Motion Control

To set up Motion Control, follow the instructions below:

1. Connect the Motion Control device to the camera using a 3BNC-to-00 Sync Cable.
   • Sync In: Connect the white BNC connector to the Motion Control device and the 4-Pin 00B connector to the SYNC port on the camera.
   • Sync Out: Connect the yellow BNC connector to the Motion Control device and the 4-Pin 00B connector to the CTRL port on the camera.
2. Go to Menu > Settings > Setup > GPIO/Sync > Sync.
3. Select MoCo from the Sensor Sync Mode drop-down menu.

4. Select the BRAIN GPIO tab.
5. Select Sync In from the GPI Function drop-down menu.
6. Select Sync Out from the GPO Function drop-down menu. (Optional)

7. Supply a pulse from the Motion Control device to sync the shutter to the rising edge of the sync input.

NOTE: For more information, refer to the manufacturer’s instructions for the Motion Control device.
