 For Diagnostics purposes, the minimal amount of boards required to communicate to the brewer from a computer is just the Microprocessor/RCA board and the [[photon_counter|Photon Counter Board]]. All the other boards can be removed. This will help diagnose if there is a bad board causing communication issues.\\
