Figure 4: FC Bus Terminal Block Wiring
Note:
The FC bus Shield (SHLD) terminal is isolated
and can be used to connect (daisy chain) the
shields for FC bus wiring.
SA Bus Terminal Block
The SA Bus terminal block is a brown, removable,
4-terminal plug that fits into a board-mounted jack.
Wire the removable SA Bus terminal block plugs on the
controller and other SA Bus devices in a daisy-chain
configuration using 4-wire twisted, shielded cable as
shown in
. See
for more information.
Figure 5: SA Bus Terminal Block Wiring
Note:
The SA PWR terminal supplies 15 VDC. The SA
PWR terminal can be used to connect (daisy
chain) the 15 VDC power leads on the SA bus.
FC Bus Port
The FC bus port on the front of the controller is an RJ-12,
6-position modular jack that provides a connection for
the FX-BTCVT Bluetooth
®
Commissioning Converter,
ZFR-USBHA-0 ZigBee
®
wireless dongle, or FX-ZFR1811
Wireless Field Bus Router.
The FC bus port is connected internally to the FC bus
terminal block. See
for more information. The FC
bus Port pin assignment is shown in
.
Note:
When an FX-PCG is configured for N2 network
communication, the FC bus port is not used.

Bus, and FC Bus Ports on Controllers
Sensor Port
The Sensor (SA Bus) port on the bottom of the controller
(
) is an RJ-12, 6-position modular jack that
provides a connection for the Bluetooth Commissioning
Converter, the VAV box Balancing Tool, specified network
sensors, or other SA Bus devices with RJ-12 plugs.
When the FX-PCG is configured for N2 communication,
the SA Bus port must be used to download and
commission the controller.
An FX-DIS1710 Local Controller Display also can be
connected to the SA Bus port (but only on FX-PCG
models without integral display and push buttons).
The Sensor port is connected internally to the SA bus
terminal block. See
for more information. The
Sensor Port pin assignment is shown in
