Edwards 3-RS485B Network Communications Card

The 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 connect the data input and output ports should the network card. Or its related Central Processor fail. Network communications may b e configured via copper or fiber media using the 3-FIBMB.
