Set the RF Channel - SyncBac PRO

SyncBac PRO is designed to synchronise with other devices in a BLINK network, so that all of the devices have the same, highly accurate clock settings. A BLINK network is a group of devices that are all set to communicate on the same RF channel.

To get your SyncBac PRO to join a BLINK network, you simply set it to use the same RF channel as the other devices in that BLINK network.

You need to set the RF Channel when:

  • You first set up your SyncBac PRO to join a BLINK network
  • Your SyncBac PRO is in a BLINK network but you want it to join a different BLINK network instead
  • You are changing the master device in the BLINK network. Your SyncBac PRO needs to have its RF Channel reset if you introduce a different master device, even if the same channel is going to be used.

 

Note: SyncBac PROs can only be part of one BLINK network. If you need to remove a SyncBac PRO from a BLINK network and set it to join another one, simply change the SyncBac PRO's RF Channel.

To set your SyncBac PRO to join a BLINK network:

  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 Set RF Channel No. option.
  5. Press the Select button.

  6. Use the Up and Down buttons to change the channel number. You need to set the SyncBac PRO to use the same channel number as the other devices in the same BLINK network.
  7. Press the Select button to confirm.

Look at the main screen to find out which channel a SyncBac PRO is set to use. The channel is shown in the bottom-right corner, next to the battery indicator.

In the image above, Ch.CE09 means the SyncBac PRO is using RF Channel 09.

Example 1: Join a BLINK network

Let's say you have three SyncBac PRO units and a :pulse unit. The :pulse unit is set to be the 'master' and uses RF Channel 4.

To get the SyncBac PRO units to synchronise with the :pulse unit, you need to set all three of the SyncBac PROs to use RF Channel 4. They also need to be set to the correct country/area and to run in RF Slave mode.

With these settings in place, the master :pulse unit will connect to the slave SyncBac PROs and set their clocks (as long as the slave SyncBac PROs are within range of the master).

Example 2: Multiple BLINK networks in range

Let's say you have six SyncBac PROs and two :pulse units and you want to arrange them in separate BLINK networks. For the purpose of this example, we will assume you want three SyncBac PROs in each network, but you could allocate them differently if you wanted.

For the first network, you set the :pulse and the three SyncBac PROs to have the correct country/area setting and to use RF Channel 4. You set the :pulse to run as the master and the SyncBac PROs to run in RF Slave mode. The :pulse and the three SyncBac PROs are all in the RF Channel 4 BLINK network.

For the second network, you set the :pulse and the three SyncBac PROs to have the correct country/area setting and to use RF Channel 6. You set the :pulse to run as the master and the SyncBac PROs to run in RF Slave mode. The :pulse and the three SyncBac PROs are all in the RF Channel 6 BLINK network.

 

The two networks are completely separate and the devices in one network will not communicate with devices in another network.

 

Example 3: Replacing a Master in a BLINK Network

If you need to change the master device in a BLINK network, you may need to set the RF channels again. This is because the slaves store the master and channel details in memory, and need to be refreshed if a different master is used.

Let's say you have a :pulse as master and three slave SyncBac PROs. They are all set to use RF Channel 05. The SyncBac PROs and their connected HERO4™ cameras all synchronise with the master correctly and filming begins.

Unfortunately, there is an accident and the :pulse gets damaged. You have another :pulse unit available, and so you swap it for the damaged one. You set the new :pulse to use RF Channel 05, but the slave SyncBac PROs do not connect with it. This is because they are 'locked' to the :pulse that was damaged.

To get them to connect to the replacement :pulse, you can either turn the SyncBac PRO slaves off and then on again to refresh their memory. Alternatively, you can set them to use RF Channel 5 again (re-applying the RF Channel also refreshes the SyncBac PRO's memory).

 

For details on country/area, see Your SyncBac PRO can communicate with other devices via radio. Before you use your SyncBac PRO, you need to set it to use the correct radio frequencies for the country you are in. This is because the regulations for the use of radio frequencies vary in different countries. .

For details on RF Slave mode, see 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..
