The product must not be stored and installed 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, etc.) and in the reach of children. Fix
the product firmly on a wall or another hard and inflammable surface with screws and dowels or fix it
to the antenna mast with folding strip, the direction of F sockets is always downward. The product
shall be in no case held only by the connected cables. Do not place any containers with liquids (vases,
glasses etc.) or naked flame sources (lighted candle etc.) on the product or near the product.

5 Product Connection and Setting up
Connect the product in accordance with this manual and valid regulation. Use high-quality 75 Ω
coaxial cable designed for satellite reception. The coaxial cables shall not be broken, the minimum
bending radius should be 5 cm. Mount the F connectors (screw, crimp or compress type) on the ends of
coaxial cables.
Before fixing of cables to the product, choose operating mode of the switch by means of configuration
levers placed on rear side of metal box, see table:

6 Setting up of satellite receiver
Proceed in setting up of satellite receiver according to chosen operating mode of the switch, see table:
Operating Principles of setting up satellite receiver
mode of
the switch
Selection of input of the switch is determined by choosing satellite position A/B/C/D,
event. LNB 1/2/3/4 or “committed DiSEqC command” AA/AB/BA/BB.
2 of 4
Selection of input of the switch is determined by setting DiSEqC 1.1 “uncommitted”
command to values 1/2/3/4.
Other switching devices connected to inputs of the product are controlled by choosing
satellite position A/B/C/D, event. LNB 1/2/3/4 or “committed DiSEqC command”
3, 4
Similar to setting of motorized antenna (DiSEqC 1.2): it is necessary for each configured
satellite to activate “move” command until expected signal is detected by the receiver;
then stop rotation immediately and save the position. Repeat the procedure for all
Configuration levers
Notes to product’s setting:
Due to more difficult setting of the receiver in modes 3 and 4, it is recommended to prefer
mode 2 whenever the receiver supports concurrent generation of DiSEqC 1.1 & 1.0
Should the cascade of two switching devices (e.g. monoblock LNB + external DiSEqC
switch) be connected to any of product’s inputs, set the lever 4 to ON regardless on chosen
operating mode.
Warning: It is necessary to reset the switch by a short disconnection of its DC supply after any change
of levers positions.
Connect the F connectors into the F sockets of product and fasten them with an appropriate force.
Connect input F socket marked TERR IN with outputs of LNBs, satellite switch or
multiswitch. Input lead that transmits also terrestrial signals must be connected to input
marked SAT IN 2 / TERR IN.
Connect output F socket marked OUT with satellite receiver.
The wiring examples are shown in the section 10 Wiring Diagrams or at website www.empcentauri.eu.
Notes to setting up of the receiver:
Mode 1: Procedure is identical to setting of common DiSEqC switches 4in/1out.
Mode 2: In case that the receiver allows to specify sequence order of sent commands, choose
“uncommitted, committed”.
Mode 3, mode 4: the switch operates as transcoder of DiSEqC 1.2 motor commands to DiSEqC 1.0
commands, which are sent to other distribution units connected to inputs of the switch. By command
“Go to zero” the switch selects input SAT IN 1 and sends DiSEqC 1.0 command position A. As long as
the command “Move to west” is active, DiSEqC 1.0 commands for positions A – B (mode 3) or A – B
– C – D (mode 4) are sent in given sequence. After that the switch selects its next input and repeats
DiSEqC 1.0 commands as described. In this matter, it is ensured that all LNBs connected to
distribution system are scanned. (Command “Move to east” would scan the LNBs in reverse order.)
If satellite signal is not detected within few minutes, turn configuration lever 3 to ON, reset the product
by disconnecting of satellite receiver and repeat the search. We also recommend to use low band
transponders (up to 11700 MHz) for scanning satellites.
USALS mode cannot be utilized.
The setting procedures of each receiver can differ, follow instruction manual of your receiver.
7 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
terrestrial and satellite receivers, TVs) during or before a storm. A lightning stroke into the
antenna may cause dangerous overvoltage in the product metallic parts.
8 Product Maintenance
Always disconnect the product from the 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. Coaxial cables installed outdoors should be
replaced once in a few years. Unscrew all F connectors and clean connector contacts, resp. shorten the
coaxial cable by approx. 2 cm, every 2 years.
9 Symbols Explanation
Certificate of conformity
International standard for digital satellite equipment control;
number (1.0, 1.1, 1.2 or 2.0) determines DiSEqC version
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.
