Note:
The NAE35 and NAE45 models with the LonWorks integration only support the upgrade
to Release 9.0. Do
not
upgrade the LonWorks models to Release 9.0.7. You must keep the LON
models at Release 9.0 or earlier.
Serial ports
The network engine has one or two RS-232-C serial ports labeled
RS232C A
and
RS232C B
1). They are designed for connecting a standard 9-pin female DTE to 9-pin female DTE null modem
cable.
For either release of network engine, you can use the
RS232C B
port to connect a Modbus RTU
third-party integration. For more information on how to use the serial port for third-party vendor
integration, refer to the application note for the particular vendor integration you are installing.
For a network engine at
Release 9.0
, you can use the RS232C A serial port in either of two ways.
First, you can connect a computer to this port for browsing the NAE35/45 through a direct
connection. For details, refer to the
Metasys® System Extended Architecture Direct Connection and
Dial-Up Connection Application Note (LIT-1201639)
. Or, you can connect a VT100 or a computer with
a VT100 emulator to this port for performing diagnostic procedures. Also, for a network engine at
Release 9.0 that does not have an internal modem, you can connect an optional external modem to
the RS232C B port. Refer to the
NAE Commissioning Guide (LIT-1201519)
for information on external
modems.
For a network engine at
Release 9.0.7
, the two RS232C serial ports do not support external
modems. Also, the
RS232C A
port is inactive.
USB port
For a network engine at
Release 9.0
, you can connect an external modem to the USB port labeled
USB
. Refer to the
NAE Commissioning Guide (LIT-1201519)
for modem information.
For a network engine at
Release 9.0.7
, the use of the USB port to connect an optional external
modem is no longer supported. However, you can use the USB port for debugging purposes when
integrating to a third-party protocol (for example, Modbus, M-Bus, or KNX).
Ethernet port
The Ethernet connection (10 or 100 Mbps) is an 8-pin RJ-45 network port (Figure 1). Use the
Ethernet port to connect to IP networks.
Optional Internal Modem
The
MS-NAE35x1-x
and
MS-NAE45x1-x
models at Release 9.0 have an optional internal modem
and a 6-pin modular jack labeled MODEM. Insert a standard phone line plug to connect the internal
modem. Refer to the
NAE Commissioning Guide (LIT-1201519)
for information on setting up the
internal modem.
Note:
The modem functionality of the MS-NAE35x1-x and MS-NAE45x1-x models is lost if you
upgrade these models to Release 9.0.7. Therefore, to retain modem operation, do not upgrade
these units.
Wiring the Network Engine
Mount the network engine securely before wiring the network engine. See the
section.
