Aquabus is the communication link between your Apex and most of the 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.
Aquabus 3′ Cable
This is a three foot Male/Male Aquabus cable that connects one module to another. This cable is included with some of our expansion modules. The 3′ cable is a great solution for when you have modules in close proximity but not right next to each other.
Aquabus 6′ Cable
This is a six foot Male/Male Aquabus cable that connects one module to another. This cable is included with our power bars and some other modules. This cable allows you to connect Apex components on opposite sides of your tank. A great example might be to connect an Energy Bar 8 on the right side of your tank and another Energy Bar on the left side of your tank.
Aquabus 15′ Cable
This is a fifteen foot Male/Male Aquabus cable that connects one module to another. This cable is intended to connect modules over greater distances. It is only included with our Automatic Feeding System (AFS). It is a great solution when needing to connect Neptune Systems’ devices above or below your tank.
Aquabus 15′ Extension Cable
This is a fifteen foot Male/Female Aquabus cable that is used as an extension cable. So if you have a 3′ foot Aquabus cable that came with your PM2 and need to go 18′, then the 15′ extension cable is the perfect solution to make that 18′ distance possible.
