4 Installation / Setup in one- or two-family homes
Setup of small installations is easy and can be done by non-professionals.
•
We recommend the use of a Satman 850 Plus outdoor unit, due to the exceptional
sensitivity of the TechniRouter even a smaller diameter dish is sufficient.
•
Use Quattro-LNBs (Low Noise Block Converter). Quattro Switch LNBs are not
suitable.
Please proceed as follows:
1. Position the antenna with the help of a suitable measuring device or a receiver.
2. Install the system, ensuring the power is not connected.
3. Be careful to ensure that the lines from the LNB have not become interchanged with
each other. To facilitate operations, it is best to use several coaxial cables with
numbering of each individual cable or marking the relevant cables, e.g. using a
suitable tack. Checking the cables to ensure that no short circuits happened avoids
time-consuming troubleshooting procedures, especially within larger systems.
4. Configure the receiver as described under point 4.6.
•
When feeding terrestrial signals into systems with more than 8 subscribers, you should
use a preamplifier when there are problems with the RF-level.
•
Unused inputs must not be connected with a termination resistor!
The following detailed advantages of the system are made possible by the use of
relatively complicated technology in comparison to conventional multiswitches. To
avoid seemingly inexplicable effects, please pay attention to the setup of the
distribution system following the instructions given in point 4.6.
4.1 Upgrading an Existing Broadband Cable Distribution as an SCR Distribution
Advantage: For the distribution itself, no new cables need to be installed. This avoids
work load, dirt and costs.
•
An existing coaxial cable set-up should be checked to ensure compatibility for signals
of up to 2.15 GHz. The easiest way to do so is to tentatively feed in a conventional
digital satellite signal at the operating point and lift this to the furthest point via an F-
plug (without the antenna socket present), and evaluate the quality at the upper end
of the band.
•
The sockets, distributors and amplifiers present must be replaced with satellite
compatible components with a DC connection.
