BACnet Device Address Rules
-- MSTP MAC Addresses must be unique for all devices connected to the same RS485 network.
-- MSTP MAC Address is configurable via parameter 5003 in the bypass.
-- Network Number must be unique for each network (IP and MSTP)
-- Network Number of 0 is reserved for broadcasts
-- Device Object IDs must be unique across the entire BACnet network, all IP and MSTP subnetworks.
-- Device Object IDs are 22 bits, configurable via parameters 5840 and 5899 in the bypass.
-- The example Network Numbers and DeviceOIDs show a good way to maintain unique DeviceOIDs
across the network.
