Thanks Harrison,
I meant that I have the same issue regardless of which reactor I choose to run my culture. I use the device at the chemostat mode and it is very unlikely that I have had any overflow that has caused this problem and I have checked for it several times. When the reactor stops by itself, I see no PuTTY window open on the screen, but the GUI is open. Then, I re-connect to enable the OD reading, but the pumps sometimes work in that condition.
I’ll update to the latest version. But, do you think the whole control computer including the BeagleBone should be replaced or just its PCB?
Thanks

Thank you. I will contact them.

Another question, and sorry if it doesn’t directly relate to topic here. But, my reactors frequently stop working and I will not know that has happened unless I go to the lab the next day. Then, I have to restart Putty and re-calibrate OD and switch on the pumps again. I was wondering if that is also related to my faulty PCB you mentioned?
Thanks

Thanks for your quick reply!

Yes, they are individually powered on with the wall plug.
It seems only M0 works cause no other device work in any combination. I can use different reactors with M0.

Thanks. The error I get as soon as I connect USB to devices M0 >0:
