The TBN can be used to set the controller’s BACnet® MAC address
and baud rate. In doing so, the TBN must have a subnet ID of 1.
To set up the network parameters:
1. Use the arrow keys to enter the controller’s MAC address.
2. Press the Menu buon to submit the MAC address.
The TBN subnet ID of 1 appears on the display.
3. Press the Menu buon once to move onto the next parameter.
The Baud Rate parameter appears on the display.
4. Use the arrow keys to set the baud rate.
Keep in mind that all the devices on the data bus must be set to
the same baud rate. Typically, the baud rate is set at the router
level. Therefore, it is recommended to set the baud rate to AUTO
so that the baud rate being used on the data bus is automacally
detected and applied to the controller accordingly.
5. Press the Menu buon to submit the baud rate.

TBN Wiring Diagram:
NOTE:
1. Dashed lines indicate new eld wiring. Sold lines indicate
exisng wiring to remain or new eld wiring by others.
2. All eld wiring must meet or exceed the requirements of the
Naonal Electrical Code (NEC) and the Sate Local requirements.
3. For inputs and outputs, the shield wire is grounded at the
controller end only.
4. Wiring for inputs and outputs is 18 AWG, shielded, twisted pair
with stranded nned copper conductors.
5. The BACnet® MS/TP network wire is 24 AWG (0.65 mm)
stranded, twisted shield pair (Jackson system part#: 24/2
BACnet®). The BACnet® MS/TP communicaon wire is polarity
sensive and the only acceptable topology is to Daisy-chain the
cable from one controller to the next.
6. Mount space temperature sensor per ADA requirements. Field
verify locaon and coordinate with other trades.
