As of firmware v1.2.5, your TCC M features two different network modes- Single Cable Mode, or Split Mode:
Single Cable Mode allows Ctrl, POE, and Dante traffic over a single ethernet cable. This allows for daisy chaining several TCCM units together - the POE Out port from the first unit connects to the POE In/CTRL of the second unit, and so on. Even if on a single ethernet cable, your Dante IP will be different from your Ctrl+ POE IP (though in the same domain.)
Split Mode acts similar to the TCC2, where Ctrl + POE is over the first PoE IN/Ctrl port, and Dante traffic is over the PoE OUT port. This will often times make sense if Dante traffic is intended to be isolated on a separate VLAN from all other traffic.
The device will restart upon changing this configuration.
