Apex accessories such as the WAV, the DŌS, and the forth-coming COR all use a new connection type called 1LINK. 1LINK is the marrying of the Aquabus communication standard, along with the power wires to drive higher power devices, all in one single cable. One of the benefits of this is to avoid the need for a DC power brick for every 24V device in your aquarium. You can use the power brick included with your 1LINK module or built into the EB832 to power three 1LINK devices!
There are two types of 1LINK cables. One is for connecting 1LINK devices together and the other type is an extension cable.
