I have and alta system with the computer and all with it communicaying with 4 compressors. I lost all comm. with compressors and traced it to this rxf39e with the comm unplugged I can read all pressures on my other three compressors. when i plug it back in i lose my comm with all compressors. My question is this a bad board?
