• A Wireless Commissioning Converter (MS-BTCVT-1) to commission the network engine with the
Controller Commissioning Tool.
• A DIS1710 Local Controller Display to provide a display screen on NCE25 models without an
integral display screen.
• An NS Series Network Sensor to provide room temperature data to the network engine.

FC Bus terminal block
The blue, keyed, removable 4-terminal block FC BUS terminal block is designed for RS485 serial
protocol field buses and is available on NCE models that support N2 Bus or MS/TP FC Bus
applications. See Figure 3 for more information. You can complete the following connections:
• Connect the 3-wire N2 Bus to the FC BUS terminal block on NCE models that support N2 Bus
applications. See Figure 3 and
N2 Bus rules
for more information.
• Connect the 3-wire MS/TP FC Bus to the FC BUS terminal block on NCE models that support MS/
TP FC Bus applications. See Figure 3 and
MS/TP FC Bus rules
for more information.
The SHLD terminal on the FC BUS terminal block is a convenient terminal to connect cable shield
drains in daisy-chain bus applications that use shielded cable.
LonWorks network terminal block
Note:
LonWorks
®
is no longer supported for an NCE at Release 9.0.7. All NCEs that feature the
LonWorks integration remain at Release 9.0 or earlier.
The blue, keyed, removable, 3-position LON terminal block connects a LonWorks network trunk
to NCE25 models that support a LonWorks network trunk. The Shield (SHD) on the LON terminal
block is soft grounded to the network engine chassis terminal, and you can use it as a convenient
terminal to connect cable shield drains in daisy-chain bus applications that use shielded cable.
FC Bus modular port
The 6-pin modular FC BUS port is available only on NCE models that support MS/TP FC Bus
applications (Figure 3 and Figure 4). Connect a Wireless Commissioning Converter (MS-BTCVT-1) to
the modular FC BUS port to commission the NCE with the CCT.
RS232C serial port
For a network engine updated with Release 9.0.7, the RS232C serial port only outputs information
during startup to a VT100 or a computer with a VT100 emulator. For a network engine at 9.0.7
configured with vendor integrations, the RS232C serial port provides a direct connection to a
Modbus RTU or M-Bus network using a standard 9-pin female data terminal equipment (DTE) to 9-
pin female DTE null modem cable. You can integrate only one device on this port.
