3 Functional earthing and cable shield
A D V I C E
The SHDSL interface is designed as a 2 wire
interface. For an effective overvoltage protection it
is mandatory to connect the functional earthing as
well as the cable shield.
A D V I C E
Any SHDSL port supports auto-crossover detection
and correction, so signals A and B may be
interchanged.
A D V I C E
The signal lines are short-circuit protected and may
be connected while the module is powered and
working.
Serial Interfaces (Con0 - Con1)
The serial interfaces of the devices are signal
compatible to RS-232. The connector is a RJ-12 female
plug. The factory pre-sets are speed 57600 Baud,
no parity, 1 stop bit, no flow control. On delivery, the
management console can be accessed via the serial
interface.

Power connector (X1)
The EDS500 devices are equipped with a wide range
power supply for voltages between 24 and 60 Volts DC
(power consumption see device label). The connector
is a 4-pin Phoenix plug with screw terminals.

The configuration parameters are stored directly

on the device. In addition, a configuration stick can

be connected to the expansion bus to save data
externally, in example to exchange defective devices
easily.

Alarm-Relay (X2)
The devices are equiped with a potential free alarm
bi-directional
output (relay with isolated switchover contact). This
output corresponds to a device alarm and is activated
when the device looses the power supply or the alarm
LED is constantly on. The reason for the signalling of
an alarm can be referenced in the system alarm table.

A D V I C E
Due to the internal overvoltage protection,
interrupt any connection to ground of the device
for the time of the measurement before you carry
out isolation measurement. This includes the
earthing of the hat rail as well as all shields of all
transmission lines and supply feedings. RJ-12 plugs
or RJ-45 plugs can establish earthing via the shield.
