K-Link is also a two-way communication, meaning the Spectral Controller X can detect the number of lights in the network, the status of the lights, etc.

The Controller X comes with one K-Link port and one 0-10V output port. The K-Link port allows users to connect to the new A360X, while the 0-10V port is for Kessil’s 0-10V light fixture (A360WE, A360NE, A80 and A160).

A single K-Link Cable comes with the Spectral Controller X.
