FAQs

Does the TC-TCNH require a separate power supply?
No, it is powered via the backplane of the host chassis (Series A or Series M rack), so no external wiring is required.

How many ports does it have?
It typically includes two BNC ControlNet ports for upstream/downstream or branching connections.

Can it work with standard ControlNet taps?
Yes, it is compatible with standard RG-6 coaxial cabling and ControlNet taps, often serving as a central distribution hub.

Is it compatible with newer C300 systems?
It is mainly used for legacy ControlNet-based systems. Newer architectures rely more on FTE, but it remains relevant for hybrid or legacy installations involving ControlNet networks.
