Help! My DRB tunnel watch computer, lost communication with the TCS. I have had replaced the Logic card, the wire that runs from the office to the TCS, the phone jack, the cable that connects from the wall to the adapter of the serial port on the back of the tunnel server. Still nothing. The logic card shows the 24v light on, but no number on the display and the amber and green lights of the communication are off. Any suggestions?
