Problem when setting up

[john.dowe]

We are having what seems to be a simple problem, but nothing we try solves it. The system does connect to the reactor, but then it indicates failure in communication. We also tested without the pump, just to be certain that it detects the reactor. It seems to try looking for a multiplex that is not connected (in both cases the control board is connected to M1. I post both outputs here:

Output with the reactor and pump:

The devices were acquired from LabMaker. We would appreciate any help
Thanks

Hi John, it looks like a faulty Multiplexer PCB. Has Labmaker gotten back to you on this front?
