1 When using BACnet protocol with N30s, you must specify UDP Port 47808 as being used. For multiple BACnet networks, use a different port number for each network.
2 In bidirectional communications, both devices initiate requests.
3 In unidirectional communication, only the originating device initiates requests (assuming synchronous response is allowed in the request).
