Aquabus is the communication link between your Apex and most of our modules. The cable itself looks just like a USB cable, but it is not to be confused with a USB cable. Connecting a computer or USB accessory, like your phone, to the Aquabus will likely result in damage to that accessory and possibly to the Apex.
There are two types of Aquabus cables. One is for connecting Neptune Systems’ modules together and the other type is an extension cable. The Aquabus cables can be connected in any manner you wish— just don’t create a loop. You can daisy chain or use the connectors on your Energy Bar to make a star configuration.
