Dear Customer,
congratulations on the purchase of the EMP-Centauri product. Before its installation and putting into
operation, read carefully the entire operation manual. Keep the purchase and rework if any) records for
future need.
1) Field of Application, Warranty
The product is designed for distribution of satellite signals in hybrid coaxial / fiber optic systems. EMP-
Centauri FIBER CLASS products are covered under 4 four) years warranty from the date of purchase, see
details in EMP-Centauri General trade conditions, published at manufacturer’s website www.emp-centauri.cz)
The user will be responsible for injury or material damage which may arise in consequence of any product use
in contradiction with the manual. Repairs or any interventions in the product may be performed only by EMP-
Centauri company, or other companies authorized by EMP-Centauri.
2) Technical Specifications
Products OMS5/10, OMS5/6, OMS9/10, OMS9/6, OMS13/10, OMS13/6, OMS17/10 and OMS17/6 are
fiber to coaxial converters - optical multiswitches for up to 16 satellite polarities and terrestrial band.
The optical multiswitches are devices with integrated optical receiver and satellite multiswitch in one common
housing. They are powered from external power supply 12V DC which is included in the package. They have
just one input for connecting of single mode optical cable from optical transmitter output, the recommended
fiber cable to be used is singlemode. The complete signals of up to 4 satellites and terrestrial TV are received
from the optical transmitter via this SC/APC optical input. The optical multiswitch is offered with ten coaxial
outputs for direct connection of satellite set top boxes.

3) Product Takeover
Make sure that the product is not damaged. Please contact your dealer in the case of damage.
4) Product Storing and Installation
We recommend the device to be installed and serviced by the qualified technician.
The product must not be stored and installed:
•in the place with excessive humidity
•in the place with dropping or splashing water,
•in the place with excessive dust pollution, mechanical vibrations or impacts
•in the place out of temperature limits specified in the section 2) Technical Specifications
•close to heat sources radiators or air ventilators, direct sunshine etc.)
•in the reach of children.
Use the apparatus only in moderate climates not in tropical climate).
Fix the product firmly on a wall or another hard and inflammable surface with screws and dowels.
5) Product Connection
Connect the product in accordance with this manual and valid regulation. Use high-quality 75 Ω coaxial
cable designed for satellite reception. Mount the F connectors screw, crimp or compress type) on the ends
of coaxial cables. Connect the F connectors into the F sockets of product and fasten them with an
appropriate force. The coaxial cables shall not be broken, the minimum bending radius should be 5 cm.
Fiber cable recommended single mode) must be terminated with SC/APC connector.
Optical transmitter:
•Connect F sockets marked “A” – “D” with LNB outputs recommended LNB type is Quattro)
•Connect input F socket marked “TERR” with output of terrestrial antenna, eventually with output
of terrestrial amplifier or channel processing equipment
•Connect output SC/APC socket to other optical device splitter, receiver)
•Connect DC2.1 socket marked “DC 12V” with power supply
•Connect connector marked with protective bounding symbol with protective bounding conductor

Note: Use only Quattro LNBs. If optical splitting is required, use PLC splitters.
Optical multiswitch:
•Connect input SC/APC socket to other optical device splitter, transmitter)
•Connect output F sockets with user wall sockets or directly with satellite receivers*
•Connect DC2.1 socket marked “DC 12V” with power supply unit – it is included in the package
•Connect connector marked with protective bounding symbol with protective bounding conductor
* RF signals applied to transmitter’s inputs appear at multiswitch’s outputs

The maximum signal level of the optical transmitter’s inputs should not exceed 85-90dBuV, there is a
significant deterioration in signal quality at higher levels.
It is recommended to add terrestrial TV preamplifier at the terrestrial input of the transmitter.
The wiring examples are shown in the section 9) Wiring Diagrams or at the website www.emp-centauri.cz.
6) Safety
Due to security reasons the product and wiring in which the product is connected, must be grounded
properly. Make sure the antennas are grounded properly. Connect all devices to power grid only after all
connections are finished and checked. Never work on the wiring including satellite receivers, TVs) during
or before a storm. A lightning stroke into the antenna may cause dangerous overvoltage in the product
metallic parts.
7) Product Maintenance
Always disconnect the product from the power supply and coaxial wiring before performing any
maintenance of the product. If you have to enter places with a risk of fall, pay attention to your safety. Use
only dry cloth to clean the product and do not use any liquid agents.
8) Symbols Explanation
certificate of conformity Protective ground Invisible laser radiation
According to EU directive, electric and electronic devices which are identified by one of the
following symbols must not be disposed of together with municipal waste. When disposing of
the old device, use local waste collection and separation systems.
