Installing the i-Vu® Open Router

Configuring BACnet Device Instance and network number

All BACnet Open controllers 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 i-Vu® Open Router's rotary address setting determines the automatic BACnet addressing scheme for the

connected Open network.

Legend

16 = Carrier's BACnet Vendor ID

xx = i-Vu® Open Router's rotary switch address (BACnet Device Instance address)

yy = Open controller's rotary switch address (MS/TP MAC address)

For the i-Vu® Open Router:

• BACnet Device Instance Number = 1600xx

• BACnet Device Instance Name = device1600xx

• BACnet IP Network Number = 1600

• BACnet MS/TP Network Number = 161xx

• BACnet ARC156 Network Number = 163xx

• Port S1 MS/TP MAC Address = 0 (fixed)

For the Open controllers connected to the i-Vu® Open Router

• BACnet MS/TP Device Instance Number = 161xxyy

• BACnet ARC156 Device Instance Number = 163xxyy

• BACnet MS/TP Device Instance Name = device161xxyy

• BACnet ARC156 Device Instance Name = device163xxyy

• BACnet MS/TP or ARC156 MAC Address = yy

• BACnet MS/TP Network Number = 161xx (learned from the router, defaults to 16101 if no i-Vu® Open Router

is operating)

If the BACnet automatic settings need to be changed, launch the Router Configuration utility using a terminal

program. See To assign a custom IP address (page 7) for instructions on connecting to and using a terminal

program.

To change the BACnet settings:

1 Enter the BACnet selection# from the menu. Type the new setting and click Enter. The new setting will appear

on the Router Configuration screen.

2 Cycle power to the router for the new settings to take effect.

NOTE If the BACnet MS/TP or ARC156 network number of the router is assigned and not auto-generated,

and the Open controllers connected to that router are set such that their BACnet settings are auto-generated,

then the Open controller BACnet settings will be auto-generated based on the assigned MS/TP network

number in the router:

Example A router's BACnet MS/TP or ARC156 network has been assigned to 200.
