WISE FLEXSWITCH
DRC 09xx
Multiswitch 9 in x, cascade, TERR. passive
Operating manual
- Cascadable multis witch for the distribution of 8 satellite polarisations and terrestrial signals
- Passive terrestrial path
- Integrated SAT amplifier for low insertion loss
- Pre-emphasis to compensate for the cable loss at high frequencies
- Terrestrial signals are available at the receiver without any power supply of the multiswitch
- High screening efficiency of Class A
- Compact dimensions paired with the installation-friendly distance between the F-connectors
- Color-coded inputs and outputs
- Made in Germany
Important Notes:
Please check the coaxial cables regarding the short circuit before starting!
The mounting ground should be:
- flame retardant
- dust-free
- protected against humidity
- not under direct impact of sunlight
- not adjacent to heating sources
Please check the input level of the SAT lines: They should be nearly equal.
All installations and fixings of components should only be executed by skilled
people when the units are disconnected from the power source. Short-circuits
have to be avoided.
The European and national standards and regulations for the guarantee of
electrical security have to be considered as well as the national permissions
and legal regulations for broadcast receiving systems!
A ground connection must be installed at the device (Ground connector) as well
as the satellite dish with at least 4 mm² cables.
Grounding and Potential Equalization
Pursuant to EN 50 083-1 the satellite antenna system must comply with safety
requirements, i.e., grounding and potential equalization.
Application:
This multis witch is used for the distribution of 8 SAT-IF-Polarizations (e.g.
ASTRA and EUTELSAT) from two QUATTRO LNBs and terrestrial signals (passive
path).
The selection of the IF-polarization is realized by the receiver control
signal 14/18 V (Vertical/Horizontal), 0/22 kHz (Low-, High-Band). The
Selection of the satellite position is done by DiSEqC 1.0. Cascade types can
be powered by the external power supply unit DRP 1533 or through SAT–trunk
lines from connected multi switches or amplifiers (please consider total
current consumption). DC-blocks have to be considered to avoid power
conflicts.
Not used cascade outputs have to be equipped with DC-blocked terminating 75
Ohm resistors.
Application example:
DC blocked terminating resistor (DV 25)
