You should set up your Timecode Systems devices so that there is one master device per network (RF channel). This ensures that all of the slave devices synchronise with the same timecode data (the timecode of the master device).
If you have multiple masters in the same network, each slave will connect to the first master that detects it. There is no guarantee that all of the slaves will connect to the same master, and so you could have slaves using the wrong timecode. To avoid this mistake, set the devices in your network to use the same unique channel.
Example: Bad Network Configuration
Let's say you have a network where all of the devices are set to use RF Channel 4. There is one :pulse master, and three SyncBac PRO slaves.
The devices in the network are all turned off and you add a new SyncBac PRO to the network. It is set to run in GP Master TX mode. When the devices are turned back on, there are two masters in the network - the :pulse and the new SyncBac PRO.
The slaves attempt to connect to the first master they find. Two of the slaves connect to the :pulse master first, and so synchronise with the :pulse. The other slave connects with the new SyncBac PRO first and so synchronises with that. As a result, the devices in the network are not synchronised to the same timecode.
