The permissible ambient temperature range is:
-20° C ... +50° C (253 K ... 323 K).
Multiswitch SMS 9987 U:
The multiswitch for 8 SAT IF signals and passive terrestrial is universally applicable, for
example:
➞➞
As an individual device for 8 receivers,
➞➞
As a cascadable multiswitch for an additional 8 receivers each (max. 24 receivers),
➞➞
In a "sandwich" configuration as an add-on component to receive and distribute
16 SAT IF signals.
➞➞
See section "Assembly instructions".
Power supply:
The UniSystem can be used where there is no mains supply. The system is powered by
the connected receivers. If the system is only being used by one receiver, a maximum
power supply of 320 mA is required.
LNB type:
The LNB inputs of the SMS 9987 U multiswitch are designed for an operating voltage
of 12 V. This means that a new-generation SMATV / Quatro LNB must be used under
all circumstances. If the current output from the receiver is not sufficently, you have to
install the SPAUN power supply SN18/600 at the terrestrial output.
Switching logic:
The SAT IF signals are selected with switching criteria 14 V / 18 V and/or 0 / 22 kHz
and tone burst or with DiSEqC commands from the receiver.
Terrestrial (5...862 MHz):
The terrestrial is routed passively in the multiswitch and is return path compatible.
Through loss is 4,5 dB; tap loss per receiver output is 27 dB.
Terrestrial antenna signals should be fed selectively to the multiswitch (system) in
order to avoid malfunctions.
