N2-configured controllers support the full range of possible N2deviceaddressesprovidedby the N2protocol standard (1-255). However, these controllers require special configuration for addresses above 127. Use the following instructions for controllers with addresses greater than 127.

Note: Before you perform this procedure, make sure that your controller has been converted from BACnet to N2 protocol first. Refer to the Modernization Guide for Legacy N2 Controllers (LIT-12012005) for more information.
Note: This special configuration is required because controller addresses above 127 were originally intended for use with the Wireless Field Bus system.
  1. Disconnect the 24 VAC supply from the controller.
  2. Remove the FC Bus connector from the controller.
  3. Set the address switch set to the desired N2 address.
  4. Set the address switch segment labeled 128 to OFF.
  5. Reconnect the 24 VAC supply to the controller.
  6. Using an SA bus connection, download the firmware and controller application file. The download process asks to confirm switching the communication protocol to N2.
  7. Click OK.
  8. After the download is finished, disconnect the 24 VAC supply to the controller.
  9. Set the address switch segment labeled 128 to ON.
  10. Reattach the FC Bus connector to the controller.
  11. Reconnect the 24 VAC supply to the controller.
