WISI DY 0508 Multiswitch 5 in x Cascade and Stand Alone
WISI PROSWITCH DY 0508 / DY 0516
Multiswitch 5 in x, cascade & stand alone
- Cascadable multiswitch for the distribution of four satellite polarisations and terrestrial signals
- Useable as a stand alone device (DG 55 power supply required)
- Stand-by function with connected power supply, optional permanent operation
- Passive terrestrial path to feed in multimedia content or signals from a cable TV operator
- Integrated SAT amplifier for low insertion loss
- Pre-emphasis to compensate the cable loss at high frequencies
- High screening efficiency according to Class A
- Stackable chassis for space-saving installation of various devices
- Colour-coded inputs and outputs
Important Notes
Please check the coaxial cables regarding 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 multiswitch is used for the distribution of 4 SAT-IF-Polarizations (e.g.
ASTRA or EUELSAT) from a QUATTRO LNB and terrestrial signals
The selection of the IF-polarization is realized by the control signal 14/18 V (Vertical/Horizontal), 0/22 kHz (Low-, High-Band) and DiSEqC 2.0 by the connected receivers.
The DY types can be powered by the external power supply unit DG 55 or through
SAT–trunk lines from connected multiswitches or amplifiers (please consider
total current consumption). DC-blocks has to be considered to avoid power
conflicts.
Not used cascade-outputs has to be equipped with DC-blocked terminating 75 Ohm
resistors.
