Insertion of the CI modules
To insert the CI modules, the covers must be removed. The picture shows the assignment of the CI slots to the
inputs. For wall mounting as shown in the picture, the double ridge guide of the CAMs must always be on the left
side. On the right side, the CAM has only a single guide ridge.
7.1 Pre-programming
The inputs and outputs of the device are pre-programmed ex-works with a standard frequency assignment. A
separate supplementary sheet with the pre-programming is included with the device. In this condition, all input
channels are present at the output. As described above, for reception of the pre-programmed ASTRA transponders,
the SAT inputs must be connected to the LNB in accordance with information on the polarization levels from the
supplement.
7.2 Input level
To ensure perfect reception, make sure that the level at the inputs is between
50 a
nd
80 dBµV
.
When receiving digital signals, it is advantageous to have a lower input level rather
than an excessively high one.
If the input level is too high, an attenuator must be used.
7.3 Output level
The output level at delivery is
90 dBµV
. This can be changed via device programming. At the TEST socket, an
output level reduced by 20 dB is available.
