2 / 9
Low power consumption for the LNB
power supply due to highly efficient
short-circuit-proof switched-mode
power supply unit which satisfies the
ERP guidelines and power-saving
concept (the single cable multi-switch is
switched off when the receiver is swit-
ched off)
Kathrein Power-Saving: The LNB power
supply is switched off as soon as there
are no longer any receivers active on the
EXE 156 or in the cascade. This function
can be deactivated if for instance loop-
through multi-switches without Kathrein
Power-Saving are used in the cascade
LNB remote feeding via the H low input.
Kathrein Power-Saving is signalled via
the V low trunk. All other inputs are
voltage-free
EXE 256
Loop-through multi-switch for system
extension by a single cable connection
for six receivers
Kathrein Power-Saving: As soon as
there are no longer any receivers active,
a signal is generated at the last multi-
switch via the "vertical low" trunk. This
signal then switches the LNB power
supply off
Single Cable-multi-switch EXE 256 and
further loop-through multi-switches such
as EXE 259, EXR 2554, EXR 2558 and
EXR 2542 can be combined as required
Up to eight multi-switches can be
cascaded
ECO mode: In ECO mode, the EXE 156
does not require a power supply unit.
The power supply for the LNB is taken
from the receiver.
EXE 256 can be cascaded with EXE 156
and EXE 256 with EXR 58/ECO or
EXE 516/ECO with no problems
INFO display: As well as the subscriber
connection, there are two LEDs. The
green LED indicates whether a voltage
is present at the H low input, and thus
the LNB has a power supply. The red
LED lights up when the multi-switch
has understood a command from the
receiver
For indoor mounting
EXE 156
Single cable multi-switch for up to six
receivers, with optional NCF 18 power
supply unit for the LNB power supply
