.2. LNB Power Supply
The power supply of the LNBs is performed by means of the power supply unit at the
multiswitch.
IMPORTANT: Use only the original Schwaiger mains adaptor!
A total maximum of 500mA are available to feed the LNB.
(18V to the LNB inputs L/H + H/H)
.4. System Cabling
- T.4 The system must have a star-topology distribution structure from the multiswitch to
the antenna sockets (e.g. Schwaiger DSE 650 or DSE 652) , i.e. only one receiver may be
connected to each output on the multiswitch. For twin receivers you require two supply lines.
- Use 75 Ohm coaxial cables for system cabling (e.g. Schwaiger KOX 110).
- Subsequent to mounting the F connectors, check the coaxial cables for short circuits.
.5. It is recommended that you terminate all the unused multiswitch inputs and outputs with
75 Ohm terminators (e.g. Schwaiger ÜST 880 201).
.6. Mounting of the Multiswitch
Multiswitches must only be installed in dry rooms with sufficient ventilation.
Moreover, multiswitches must be mounted to a hardly flammable ground.
IMPORTANT:
During constant operation at 25°C room temperature, some parts of the multiswitch carry a
temperature of up to 55°C, depending on the current input of the LNB type used.
.7. Protective Arrangement
The multi switch needs to be grounded by way of its grounding terminal!
