For an NAE55 at
Release 9.0
, you can use the RS232C A port to connect directly to a computer
serial port to browse to the NAE55. Use this port only for establishing a Point-to-Point Protocol
(PPP) network connection. Refer to the
Metasys System Extended Architecture Direct Connection and
Dial-Up Connection Application Note (LIT-1201639)
. Use the RS232C B port to connect with a VT100
terminal or computer using a VT100 terminal emulator because the RS232C B port outputs the
device IP address. Use this port only to obtain the NAE55 IP address at startup. Refer to the
NAE
Commissioning Guide (LIT-1201519)
.
For an NAE55 at
Release 10.0 or later
, the
RS232C A
port is inactive. However, 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.
Universal Serial Bus (USB) ports
The two USB ports labeled
USB A
and
USB B
are both configured as masters and are independent
of each other. At Release 9.0, you can use USB A port to connect an optional external modem. Refer
to the
NAE Commissioning Guide (LIT-1201519)
for more information on external modems. At Release
10.0 or later, the use of a USB port to connect an optional external modem is no longer supported.
However, you can use either the USB A or USB B port for debugging purposes when integrating to
a third-party protocol (for example, Modbus, M-Bus, or KNX).
Optional Internal Modem
MS-NAE55x1-x and MS-NIE55x1-x models with Release 9.0 have an internal modem and a 6-pin
RJ-12 modular jack labeled
MODEM
. Connect a standard phone line plug and cable to the to use the
internal modem.
For information on commissioning an internal modem, refer to the
NAE Commissioning Guide
(LIT-1201519)
.
