RG- thanks for the reply
I presume I would need to assign the addresses via USB as per pumps and use a Y splitter cable on the flow connector?
Correct, and also remember that if you desire to use the MPS' without the USB Cable connected you will have to use 4 Pin Aquabus Cables to supply the +5V to the MPS'
Also ensure that the "Y" splitter you use includes all 4 wires to both ends.
