Configuring BACnet Device Instance and network number
The TV-MPCXP1628-NR controller must have a unique Device Instance and Name. These BACnet addresses are
automatically generated and usually do not require modification. However, sometimes you need to override the
automatic addressing assignments.
Autogenerated addressing scheme:
The TV-MPCXP1628-NR's rotary address setting determines the automatic BACnet addressing scheme for the
connected Open network.
