Set the Timecode Mode - SyncBac PRO

SyncBac PRO has two different Timecode modes: RF Slave and GP Master TX. These modes define how your SyncBac PRO's clock is synchronised with other devices, and so it is important that you choose the appropriate setting.

Note: If you are unfamiliar with the concept of master and slave devices, please read Clock Synchronisation - Master and Slaves.

To set the Timecode Mode:

  1. Connect your SyncBac PRO to a HERO4™ (if it is not connected already). For further details, see Connect SyncBac PRO to a GoPro HERO4™.

  2. If your SyncBac PRO is currently off, switch it on (see To switch your SyncBac PRO on:).

  3. Press the Select button.

  4. Use the Up and Down buttons to scroll to the Timecode Mode option.
  5. Press the Select button.

  6. Use the Up and Down buttons to scroll to the appropriate mode:

    OperationTimecode Mode

    SyncBac PRO is master and sets the clock of:

    • Its own HERO4™ camera (the HERO4™ camera that is connected to the master SyncBac PRO)
    • Other SyncBac PROs in the same BLINK network.
    GP Master TX
    SyncBac PRO is slave and has its clock set by another device in the same BLINK networkRF Slave

    *When a SyncBac PRO is free running and in RF Slave mode, it uses its own clock settings but continues to search for a master on the same BLINK network. If it finds a master, the master will set the clock.


    Note: A SyncBac PRO can only be the master to SyncBac PRO slaves - it cannot be a master to :wave, :pulse, or minitrx+.

  7. Press the Select button.

  8. Use the Up and Down buttons to set the RF Channel that the SyncBac PRO will use to communicate with the master device. The master device can only communicate with slave devices that use the same RF Channel as the master.
  9. Press the Select button.


The following table shows how you should set your SyncBac PRO when there are other Timecode Systems devices in the same BLINK network.
