I found a spare CNA board in the machine room. Who know if it’s good or not. I swapped it out with the board on the controller and now I have restored communication and the unit is running. However now I do not have any hall Gongs, PI’s or lobby PI. After a TECCV it responds with all the CN0 ports are working now but CN1: 1-5 and 11 still failed to respond.
