MAC Address
The MAC Address is required by the RS-485
communication protocol on which BACnet operates. A
UC400-B controller can use a MAC Address from 001 to
120.
Important: Each device on the link must have a unique
MAC Address/Device ID. The controller rotary
addresses should be sequentially set, with no
gaps in the numbering, starting with 001 on
each link (for example 001, 002, 003, 004 and
so on). A duplicate address or a 000 address
setting will interrupt communications and
cause the Tracer
process to fail.
