The Shifter Bd. is plug-and-play. the FCB Bd. is jumpers for the floor, and used for the Arrival gong, and Door side. The Gateway Bd. is for Duplexing. Does the CPU show the LON Net as off? If you have a Duplex the Gateway LED # L1 shows the LON chip towards the CPU as working properly and # L3 towards the other elevator working properly if they are green. Also the CPU has an LED for the Car LON and an LED for the Hoistway LON, which one is off?
