About this task

Use the BACnet Router feature to add all the controllers under the control of a SBH, into a larger supervisory system through BACnet/IP integration. You can use this feature in a number of situations. For example:
  • A new addition
  • A segregated wing of a building
  • A remote building that you want to tie into an existing Building Automation System (BAS).

The SBH has a list of devices on the system bus that connect by RS-485 and an active BACnet/MSTP. When the BAS sends out the Who-Is message, the SBH responds for itself and all devices under its control. Optionally, you can set up a BACnet IP Broadcast Management Device (BBMD) if the SBH and BAS are on different subnets.

To configure the BACnet router feature, complete the following steps:


  1. Navigate to the Settings tab.
  2. Under the Settings tab, select the BACnet Settings option and adjust the following parameters:
    • Device Object Identifier – Identifies the SBH as a unique device on a BACnet network. Adjustable: 0 to 4194303, default 1.
    • MAC Address – Sets the address on the system bus for the MS/TP network. Adjustable: 4 to 127, default 117.
    • Network Number – Sets the routing address for devices under the SBH. Adjustable: 1 to 65534, default 64999. It is best practice to leave the network number on the default setting.
    • Routing Mode – In this mode, the SBH utilizes the routing feature that identifies MS/TP devices over the IP integration. The routing function of the SBH disables by default.
    • UDP Port – Defines the port for the UDP traffic. By default, BACnet uses 47808 but you have the optional use of other ports. Adjustable: 47808 to 47823.
