4.6 REAL-TIME CLOCK WIRING (PTC901) Time synchronization between multiple PTC901 meters can be accomplished through a hardware interface on the Real-Time Clock option card. This RS485 type interface allows connection of up to 32 PTC901 meters in a two-wire multidrop network, at distances up to 4000 ft. In a synchronization network, one PTC901 meter is programmed as the Host, while all other meters are programmed as Slaves. Once every hour, the Host meter outputs a time synchronization pulse ont
