Strange problem on a job we just picked up. The unit is a six stop duplex. The route guy called me and said that the car would not register or latch the top floor car call (6th). The car call can however be set via the service tool but the call button does not latch or register via the car station. We tried changing the RS call button modules in the car station with two newer modules but still no luck. The job does have floor security but independent service overrides this. I verified the floor security inputs where non active by 1) comparing the signals to the other functioning car 2) trying the car on independent service an 3) swapping the RS -modules that the security is wired to between cars. I tried swapping the 4 pin serial link plugs in the car station thinking that maybe we had a bad connector. We have another of these jobs which seems to be notorious for bad connectors. Any clues guys?
