In all cases, the great advantage is that suitable, existing
tree structures in the buildings can continue to be used.
No special network structures and therefore construction
measures are required.
Digital reception is possible only with a cable SET-TOP
BOX (e.g. ASTRO ASR 530).
Configuration software
Using the optionally available configuration software
(Windows-compatible, including connection cable and
adapter), all headend parameters can be set simply and
clearly and then saved.
Laborious searching for the right input SAT intermediate fre-
quency is no longer necessary because all program para-
meters of the commonest satellites are stored in a data-
base. The user only has to enter the satellite, the LNC
oscillator frequency, the desired program and the output
channel. All other parameters are read from a database.
The user can update the databases or download the latest
data from the ASTRO server via the Internet.

Connecting to SAT equipment
Cabling:
•
Connect the SAT signals from the LNB to inputs X and Y.
•
The internal distribution field routes the input signals
without noticeable transmission loss to the SAT loop-
through outputs (forwards SAT signals to the next X-5…
device). Because of the signal quality, maximum 3 base
units should be cascaded
•
Additional feed of 10 polarizations / bands via inputs
“EX 1” to “EX 10”.
Note:
•
There is no LNB supply voltage at inputs “EX 1” to “EX 10”!
•
Use quality SAT components and SAT compatible
coaxial cable.
•
Install the F-connectors carefully and correctly.
•
If not used, close the SAT loop-though outputs with 75-
Ohm terminal resistance.
Important:
The above advice is very important. Many errors are often
due to incorrect cabling and have a strong influence on any
subsequent cascading
5.1
LNB supply
•
Switching on/off the LNB power supply via software
(chapter “Programming”)
The total current must not exceed 250 mA.
•
LNB power supply is short-circuit-proof.
•
Exceeding the maximum feed current results in a
forced switch-off of the LNB supply voltage.
•
Switch-off of power supply of cascaded devices (LNB OFF)
•
Inputs “EX 1” to “EX 10” have no LNB power supply option.
