Luckily it will work off of the aquabus and included power supply. If you happened to already have a 1-Link module(WAV) or have the new Apex, then you can do away with the power supply that is included with the DOS.
If you have the newer Apex, you can purchase a 1Link cable so you do not have to run a power supply AND aquabus. This is what I did and I feel it is the best solution due to the reduction of wires.
