I unplugged my 2016 apex to try out a different brain (switching out the aquabus cable for the eb8, temp/ph probes, and ethernet). Once I plugged everything back in, I can no longer control my original EB8 via the display/apex fusion. However, I am able to control a dc8 I have connected. Anyone have any suggestions on how to get back to being able to control the EB8? I've restarted the system several times.
