Neptune Apex 1LINK Base Module

It is called 1LINK simply because there is one power supply, one module (for up to three 1LINK devices), and a one-click-connection of a wire that carries not only the power for the device, but two-way communication from it to your Apex. Setup is simply click and go.

Less wires, less configuration headaches, and best of all, less cost to you as a consumer!
