Hey,
Bought these a while ago and was unsure if the software was able to do this as yet? Bought the 3 pin fan cable to connect the aquabus (which I was told was how it was going to be setup so that the LT is a slave) and currently its plugged into the "high" side plug on both. Both are also connected to the computer via a usb cable. When I open aquasuite I can connect and see all the information for the XT however when I try and see the settings and things for the LT it just doesn't work and crashes. It also comes up with the following error and as soon as you click ok, it then closes/crashes the program. http://imageshack.us/photo/my-images/705/unledujz.jpg/

Any help would be great, and both cards have the latest 1013 firmware (i think thats the version that is the latest)

Thanks
Tyler

EDIT: also do you have some stats on flow rate or anything like that for the aquastream xt? Currently using 2 x mcp-655's in series (getting 170ish litres per hour) and looking at replacing them with the 1 aquastream xt in the hope of higher flow rates.

Thanks shoggy, worked a treat. Now i have access to both. Haven't really explored this yet, but could i potentially setup the XT so that any sensors that are on the LT come up on the lcd display as well?

Thanks for the pump flow. Do you have any more info such as flow vs pressure drop charts, or even a "normal" loop flow rate for the following pumps? Looking for comparisons to see if its worth it.

aquastream XT USB 12V Pump (all three versions, if it makes a difference at all which from what i read it does not)
Eheim 1250 (Version Germany) - also whats the difference with version germany?

Also, how many aquastream XT's can you connect to an aquaero XT and LT each? Possibly looking at putting two in each loop with 1 flow meter for each loop. Could you also mix a standard and an ultra? Seeing as you'd only really need 1 internal temp sensor, and the 1 flow meter? And what kind of performance gain would having two in series get you? Alternatively would two in parallel get you greater performance gains?

Thanks
Tyler

Thanks again for that info. Good to finally find a flow chart for it.

I've heard that the pumps automatically sense the load and adjust the pump, and when put in series this causes problems as neither senses the full load and as such doesn't spin as fast as i probably needs to. Is there a way to manually (or automatically via some configuration much like you do with the fans) set the frequency/flow rate of the pumps if you had them in series?

Thanks
Tyler

Excellent, thanks for that again.

Last questions, if you put them in series with each other, in theory the pressure would drop as they're both helping to push water and as a result the frequency would be lower, but would they run at the same frequency?

Also if you put them in parallel would you in theory get a situation where you wouldn't get a greater water head, least not by much, but much greater flow as both would be working to push the pressure hence working at the same/higher frequency?

Do you need to plug every pump into a usb port? or will plugging them into power, and to the aquaero suffice/be enough to control them fully? Can you plug the aquastream into the aquabus on the aquaero as well as have a flow meter plugged into the pump? Or do they share the same header on the pump and the only way to get it to work would be to plug the flow meter into the aquaero in the flow meter plug? Found out its one or the other

Do you also have some diagrams/measurements of the aquastream XT? Looking at linking them and need to know distances of the inlets/outlets so I can get the right fittings.

Thanks again for all your help shoggy
