Manual Device Instance Numbering
Prior to June 25, 2014, only automated Device Instance Numbering was supported. The
FW2014.06.25 firmware release added support for static Device Instance Numbering.
This section describes how to statically set the Device Instance Numbers.
The System Controller defaults its Device Instance Number to 654000. This can be
changed to any valid BACnet Device Instance Number (0-4194302). From the Touchpad,
this configuration item is under Menu->System Configuration->System->BACnet Instance ID.
This is the Device Instance Number that will be used for the System Controller.
The System Controller can also be set to auto number the remaining devices under Menu-
>System Configuration->System->BACnet Auto Number. This can be useful if you need to set
the Device Instance Numbers to be within a certain range but do not care what the Device
Instance Number is for a particular device.
The following is a modification to the previous example in which only the System
Controller’s BACnet Device Instance Number is modified in the configuration.
Scenario 2a:
System Controller IP Address: 10.20.21.100
System Controller BACnet Device Instance Number: 500
System Controller BACnet Auto Number: Yes
