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 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 .

Power connector (X1 and X3)
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.
Devices supporting Power over Ethernet (PoE) do have
an additional 4-pin Phoenix power plug. The input
voltage depends on the Rubrik of the device.

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 measurements. 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 also establish earthing via the
shield.
