Hi Both,
I seem to be having the exact same problem, have you managed to resolve it, and if so how?
I am also a bit unsure what the “multiplexer” really refers to, is it the “blue Chi.Bio Control board v1.1” that likely need replacement?
We have the 8-reactor package from Labmaker, so I tried it with different reactors / pumps, same message.
Thanks,
Gergo
