I have connected both quadros to USB headers and assigned different addresses.
I can get them to work though the USB port with a fan curve for temperature of the water, and the flow sensor works as well.
Once I connect them to the Aquero with the aquabus x4 nothing works, and the Aquero does not show anything on the screen like it is not getting power. Once I remove the aquabus cables from the X4, the aquero shows stuff on the screen again.
Not sure where to go from here..
Thanks
