About this task

N2-capable controllers support the full range of possible N2 device addresses provided by the N2 protocol standard (1-254).

To configure a controller to communicate using the N2 protocol, complete the following steps:

Procedure

  1. Disconnect the 24 VAC supply from the controller.
  2. Set the address switches to the desired N2 address. For details about setting a device address, see Setting the device address.
  3. Reconnect the 24 VAC supply to the controller.
  4. Using an SA bus connection, download the firmware and controller application file configured for N2 to the controller.

Switching the Communications Protocol from N2 to MS/TP

About this task

For N2 sites that are converting to BACnet MS/TP, you can switch the communications protocol of N2-configured MS/TP controllers back to BACnet MS/TP.

To switch the controller operating in N2 mode back into BACnet MS/TP mode, complete the following steps:

Procedure

  1. Disconnect the 24 VAC supply from the controller.
  2. Set the address switches to the desired BACnet MS/TP address. For details about setting a device address, see Setting the device address.
  3. Ensure the DIP switch 128 is set to OFF.
  4. Reconnect the 24 VAC supply to the controller.
  5. Using an SA Bus connection, download a controller application file configured for BACnet MS/TP to the controller.
