NCM that has two N2 Trunks, because the
NCM45x0-2 supports one N2 Bus

The N2 Bus termination on the NCM350/361 is
labeled N2 Bus, whereas the N2 Bus termination on
the NCM45x0-2 is called

Field Controller (FC)

Bus.

Also, the old N2 connector has three terminals,
whereas the connector on the NCM45x0-2 has four
terminals, including a termination for shield. If you
re-use the N2 Bus connector from the old NCM, be
sure to mate the connector toward the correct side of
the FC Bus terminal block. If using N2 Bus wiring that
includes a shield, refer to the

N2 Communications

Bus Technical Bulletin (LIT-636018)

for additional

information on terminating a shield.

The

terminal block on the NCM350/361

is not compatible with the L

W

ORKS

network terminal

on the NCM4520-2, so it cannot be reused. Instead,
use the new terminal block provided. LON network
wires are not polarity sensitive.

For the NCM45x0-2, the Ethernet and LON Network
components are built into the motherboard; separate
network cards are not required.

The serial ports on the NCM45x0-2 are not labeled
the same as the serial ports on the NCM350/361. Port
3 on the older models is equivalent to the
RS232C A/Port 3 on the NCM45x0-2, and Port 5 is
equivalent to RS232C B/Port 5. A device connected
to Port 3 on the NCM350/361 can be moved to

RS232C A/Port 3

on the NCM450x-2. A device

connected to Port 5 on the NCM350/361 can be
moved to

RS232C B/Port 5

on the NCM45x0-2. Serial

Ports 2, 4, and 6 on the NCM350/361 models are not
offered on the NCM45x0-2. If a serial port currently
in use is no longer supported on the new NCM,
database configuration changes are required. Refer
to the

NCM45x0-2 Network Control Module

Commissioning Guide (LIT-12011176)

for details.

Serial Ports 2, 4, and 6 on the NCM350/361 models

Commissioning Guide (LIT-12011176)

for details.

Before removing the NCM350/361, upload its
database to the archive

Operator Workstation (OWS)

so that it can be edited later and eventually
downloaded into the new controller. Refer to the

NCM45x0-2 Network Control Module Commissioning
Guide (LIT-12011176)

for details.

While the NCM45x0-2 is restarting, the LEDs on the
unit are not used to indicate its network address or
act as diagnostic indicators of a particular error
condition. The only LEDs that indicate failure are the
Fault and Batt Fault LEDs.

FC

or LON terminal, USB port (not used), and Ethernet

.

Power Supply

In North America, the

NCM

requires a dedicated Class

2, 24 VAC, 25 VA minimum power supply. Outside North
America, use a 24 VAC

Safety Extra-Low Voltage (SELV)

transformer at the appropriate rating. The minimum input
voltage for the NCM to operate properly is 20 VAC.
Maximum power consumption is 25 VA.

FC Bus Terminal (NCM4510-2 Only)

The

FC

Bus network terminal on the NCM4510-2 model

is a 4-position removable, keyed terminal block. Use the
FC Bus terminal to connect field controllers that reside
on the N2 Communications Bus.

See

Table 1

and refer to the

N2 Communications Bus

Technical Bulletin (LIT-636018)

for additional information

and guidelines on wiring devices on an N2 Bus.
