Operation
The compact modem 500NMD44 has two optical
interface as SFP plug-in and four Ethernet interfaces.
There are two serial interfaces for configuration or
process interface (e.g. to connect telecontrol units). A
configurable alarm relais and an extension interface
(e.g. to use the configuration stick) complete the
device.

Connections
Ethernet interfaces (Port1 - Port4)
Every Ethernet interface detects automatically
whether the connected counterpart works as
transmission or network termination device. This way
both normal and crossover cables can be used (MDI/
MDI-X).

The Ethernet interface can operate at transmission
rates of 10 or 100 Mbps, depending on the connected
devices in half duplex or full duplex mode. The
operation mode is detected and set automatically
by the EDS500 devices. A manual configuration is
possible.

SFP Interfaces (Fo1 - Fo2)
All SFP interfaces are designed according to Small
Form-Factor Pluggable (INF-8074i).
W A R N I N G
Only transceivers up to laser class 1 according to
EN 60825-1 are allowed to be used for the SFP
interfaces.
A D V I C E
Any warranty claims can only extend to SFPs
delivered by ABB.
Serial interfaces (Con0 - Con1)
The serial interfaces of the device are signal
compatible to RS-232. The connector is an RJ-12
modular jack. The factory presets are speed 57600
Baud, no parity, 1 stop bit, no flow control. Via the
serial interfaces the management console can be
accessed .
