Bacnet Serial Port Settings; Bacnet Device Instance Id; Auto Baud Rate; Bacnet Points - Honeywell TR50 User Manual

By default, all the DIP switch address are OFF, so the MAC address will be assigned
automatically.
Below are the default MAC address details. Engineers can assign MAC address
manually via DIP address switch.

4.4.4 BACnet Device Instance ID

By default, the TR50 IAQ Sensor device will use MAC address as BACnet device
instance to benefit initial device discovery process for TR50 commissioning.
After TR50 device is discovered, commissioning engineer take the responsibility to
assign a unique BACnet device instance across inter-network. For more details
about device discovery and device ID refer Niagara Engineering Guide Smart
Sensor section.

4.4.5 Auto Baud Rate

The TR50 IAQ Sensor device will be running in adaptive baud rate mode.
The adaptive baud rate will work in the first 4 minutes after the device is power ON.
Choose a valid baud rate (9600, 38400, 19200, 57600, 76800, 115200). If the valid
baud rate can not be found in this period, device will look in flash for the baud rate
found last time, if failed again, use default 38400.

4.4.6 BACnet Points

Use the BACnet MSTP network to discover and add the TR50 IAQ Sensor device.
Refer Niagara/CPO Engineering Guide Smart Sensor device discovery section for
more details.
After the device is discovered, different BACnet points will be created as per SKUs.
These points are used to configure below sections as desired.
