Note: If you set the rotary switch values to a number between 001 and 419, the Tracer
To set the rotary switch values, use a small screwdriver to turn the three rotary switches on the Tracer
SC+ to a unique number between 001 and 419.

BACnet MS/TP Device ID Assignment
Each unit controller must have a unique BACnet
calculating a unique device ID for each unit controller and then saving the device ID to memory in each
device.
For Tracer
following three sets of values:
•
•
•
The three values are joined together to form the BACnet

SC+ has a set of three rotary switches on the front of the device, which are used to set the

Device ID. The rotary switch range is 1 to 419. Zero (0) cannot be used because it is the default
