What Sabastian is trying to say is that you must set each pump ID with the USB cable and AS2012. Actually, You only need to set one pump ID, the other one can stay at the default number.
But what you want is two of these:
http://shop.aquacomputer.de/product_info…roducts_id=2847 I think that the pumps and flow meter are shipped with a four wire double female cable, so that should give you lots of wires to hide. Just connect one splitter to the high speed Aquabus connector on the Aquero 5, an then a second splitter to one leg of the first one. that will give you three male Aquabus connectors, then go from each of those to the units you are installing. Done. Connect a five wire USB cable from one of your pumps to the motherboard, yes, you will have both Aquabus and USB connected to the pump at the same time, that is OK, and just temporary.
Fire up Aquasuite 2012. On the left side of the screen, there should be a tab for Aqustream D5 or somesuch, probably two of them, just open one and change the ID number, if you can't find the ID number, try the other pump page. One of them is the pump through the USB connection, the other is one, or both pumps through the Aquabus. If you cant find it, just pull the Aquabus cable from the D5's and try again. I have a AQD5 on my wish list, or I could give you a better idea of how this works. But I think it can be figured out fairly easily.
Just out of cureosity, I would look at the control panel of your system and see if the pump shows up as a USB device.
Happy hair pulling!
This is a wonderful system, and very flexiable, unfortunatly, the documentation really sucks. Some times I think of starting a thread for the English Speakers to write the manuals for AC based on lessons learned here in the forums, but then I wke up and the nightmare is over.
