PowerAdjust 2 / Pump Setup
This week I have been working on getting the AquaCompuer PowerAdjust 2s all sleeved up and ready to hook into my system. These will be used to control the speed of my pumps either via an Aquaero 5, or independently via a temp sensor. I have not yet decided which way I am going to go (Aquaero 5 or Corsiar Link) for my fan controller, but until then, I will at least get my pumps set up and get a liquid "flush" through the system with some distilled water.
Here is the prep work I did to dye the cables from my pumps black, along with the USB header cables that connect to the Aquaero 5 and PA2s. It is actually vinyl dye, not spraypaint, so it doesn't flake off when bending the cables. In one of my last builds, I had a bunch of questions about the dye, and what kind I used, so I decided to include a picture of it in the build log this time around.Larger Image
I also wired up the PowerAdjust 2's after a bit of Questions / Answer sessions on the Aqua Computer English forum. It wasn't clear to me how to modify the cable on my pump to correctly interface with the PA2, so I did a little sketch and asked which option was better to use since my pumps are not controlled via PWM. Option 1 was the correct wiring method as seen below. Next to it is a picture of the 5pin power connectors going to the PA2s, along with the "AquaBus" jumper cable connecting the controls for the two pumps. You do have the option to control each one independently, but I want both my pumps operating at the same speeds.Larger Image
There is an important step that has to be done if you plan on using more than 1 PowerAdjust modules for pump / fan control. Each has to be given a Unique ID number to be see all the fan channels correctly in the software. Here is what you have to do in order to get 2 or more working together.
First, you should setup your Poweradjusts using the older Aquasuite version 4.72, which you can get here
. Once installed you need to connect each Poweradjust (one at a time) over USB, to then update your PowerAdjust frimware and then adjust its Aquabus address. Once you have loaded up AquaSuite, select "Firmware" from the PowerAdjust 2 menu and update to v1003.
Now you must give your PowerAdjusts a unique ID. I gave one the address of 51, the other is 52.
Once this is done, you can disconnect the USB, plug them in over Aquabus and you should see extra fan channels in your Aquasuite 2012. Of if you don't plan on using Aquaero for your Fan Controller, you can leave them plugged in via USB for independent control. Next up... distilled water flush, and Fan Controller Battle Royal
