What does SAT-CR mean?
SAT-CR stands for Satellite Channel Router.
This technology enables the delivery of broadcast programs to multiple users over a single coaxial cable.
This standard allows a tree architecture instead of the standard star architecture which is commonly used in the SAT-
IF distribution. SAT-CR technology enables to connect up to 8 receivers on a single coaxial cable. Compared with
headends SAT-CR allows to receive the entire channel offer of up to two satellite positions.
There are no limitations.
How can I install the SUS 5581/33 NF(A) LEGACY?
The SUS 5581/33 NF(A) LEGACY can be used as a stand-alone device or within a cascadable system. This makes
a mixed system possible with SAT-CR devices and common cascadable multiswitches (for instance SMK 55xx3 Fx).
The launch amplifier of a cascadable system remote powers the devices via terrestrial trunkline (SBK 5502/03, NFx).
If you use the SUS 5581/33 NF(A) LEGACY as a stand-alone device you can use the wall socket power supply which
is included in scope of delivery.
Why does the SUS 5581/33 NF(A) LEGACY have two different operating modes?
The SUS 5581/33 NF(A) LEGACY allows to switch between two different operation modes:
In position 1x8 (1 output, 8 receivers) up to 8 receivers can be connected in series on a single coaxial cable.
In position 3x3 (1 output, 3 receivers) up to 9 receivers can be connected to three outputs each three receivers.
In the 1x8 operating mode, the two unused outputs can be used as conventional multiswitch outputs (Legacy mode).
What kind of sockets shall I use for the SUS 5581/33 NF(A) LEGACY?
Generally, the SPAUN SUS 5581/33 NF(A) LEGACY can be used in combination with all available wall through so-
ckets which have a DC-power pass. In order to obtain the best performance of a SAT-CR system we recommend to
use the UNiSockets. These sockets are available with optimized through loss for the use with the SPAUN UNiSEqC
product line.
How can the SUS 21 F be used?
With the SUS 21 F it is possible to connect 2 receivers or one PVR (Dual Tuner) receiver through a single coaxial
cable. It is necessary that the connected receivers support the SAT-CR command set according to EN 50494. The si-
gnals from max. 2 SAT position (8 SAT IF signals) and terrestrial can be received. For instance if the SUS 21 F is used
in combination with a SMS 17089 NF the user can receive the first two satellite positions (8 SAT IF signals, positions
A & B). The positions C and D (SAT IF signals from 9 to 16) are not available. The input jacks of the SUS 21 F have
margin of 20 mm therefore the SUS 21 F can be directly connected to almost all available SPAUN multiswitches.
Naturally the SUS 21 F can be also combined with non SPAUN devices. The Universal AC Adapter SNG 18/1000 can
be used to feed the system if the used receiver is not able to power the distribution system.
