Edwards 3-RS485B Network Communications Card Notifier FSP-851(A) Series intelligent plug-inThe 3 RS485B card provides a Class B (Style 4) or Class A (Style 7) circuit for network communications signals. And a second Class B (Style 4) circuit for the digitized audio signals. Network messages the Network Communications card receives a re re transmitted to the next network node. Re transmission maximizes the wire run lengths between nodes. With 64 nodes, miles of network length is possible. Fail safe mechanisms built into the card directly
