Configuring N2 communications (CVM
models only)
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 CVM controller to communicate using the
N2 protocol, complete the following steps:
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 on CVM models .
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
controllers back to BACnet MS/TP.
To switch the CVM controller operating in N2 mode back
into BACnet MS/TP mode, complete the following steps:
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 on CVM
models .
3. Reconnect the 24 VAC supply to the controller.
4. Using an SA Bus connection, download a controller
application file configured for BACnet MS/TP to the
controller.
Configuring wireless communications
(CVM models only)
About this task:
To configure a controller for use with the ZFR Pro Series
Wireless Field Bus system, complete the following steps:
1. Disconnect the 24 VAC supply from the controller.
2. Wire the input/output terminals and SA Bus.
Note: In wireless network applications, do
not connect any wires to the FC Bus terminal
block. (Connect the SA/FC terminal block on
an expansion module to an SA Bus only.)
