Device Addressing

The Network Guide provides extensive information and requirements to implement a BACnet MS/TP network. It contains information about network plan-
ning and MAC Address numbering schemes. It can be downloaded from the
to the guidelines outlined in the Distech Controls UUKL Smoke Control System Design Guide.
The MAC Address must be set according to your network planning document by setting the DIP switch located under the cover or when this DIP switch
is set to 0 (all off), the MAC address can be set by connecting an Allure EC-Smart-Vue Series Communicating Sensor to the controller as shown in Step
5 of Setting the Communicating Sensor Subnet ID in the following section. An example of how to set the device's MAC Address DIP switch is shown be-
low.
Figure 15:
MAC Address DIP Switch Set to 82
DIP Switch number 8 must be set to OFF at all times.
The address is the sum of the numbers set to ON. For example, if the second (2), fifth (16), and seventh (64) DIP switches are set to ON, the device
MAC address is 82 (2 + 16 + 64). Only addresses from 1 to 127 are recommended to be used.
The controller must be power cycled after the MAC address DIP switch has been changed. The device instance (DevID) is automatically configured
when setting the MAC Address to prevent network address conflict. The following formula is used to determine the device instance:
DevID = 364 * 1000 + MAC
For example:
MAC: 37
DevID = 364 * 1000 + 37 = 364037
The Device Instance can be changed once the controller has been commissioned through the network management software interface.
