5 / 4
Single-cable mini-multi-switch for distribution of digital
Sat IF signals (including HDTV) and terrestrial signals
via a single cable, for one twin receiver or two single
receivers within a single-family household
No restriction on the variety of channels - the
complete range of channels from up to two satellites
is transmitted
The single-cable mini-multi-switch does not contain its
own switching matrix. It is therefore driven from two
free connections of a multi-switch (such as EXR 2908)
or from two connections of a twin or quad feed system
(such as UAS 585)
The single-cable mini-multi-switch generates from the
output voltage of the receiver the 14/18V and 22 kHz
necessary for controlling and supplying the connected
multi-switch or feed system, and for the DiSEqC
TM
commands
When all receivers are switched off , the single-cable
mini-multi-switch draws no current
Special tuner modules called SCRs (Satellite Channel
Routers) for conversion to the subscriber frequencies
are incorporated within the single-cable mini-multi-
switch for for transponder selection
Each receiver is assigned a fi xed subscriber frequency
(a twin receiver requires two subscriber frequencies)
The unit satisfi es the SCR single-cable standard to
EN 50494, which means the connected receivers must
also satisfy this standard
The terrestrial range 5-862 MHz can be received via the
input A even when the Sat receiver is switched off
For operation of a feed system with more than 80 mA
or a multi-switch with more then 2 x 40 mA current
consumption, it is necessary to connect the NCF 18
power supply unit (not included in the scope of supply)
to the socket marked “DC”
For indoor installation
