The modulator modules can be mounted either to SKS 4-0x or SKS 8-00 system or stand-alone
2.1 Installation and connection in a headend base unit
If you want to operate the SKM 1-01 on a headends basic unit SKS x-xx, plug the module into the output
combiner (1) and fasten it by screws. Each free slot may be used.
The power supply unit SKZ 5-01 or SKZ 6-00 supplies the module via the active output combiner. Signals
from AUDIO/VIDEO source are fed to Audio/Video inputs of the modules (see Fig. 2).
Fig.
Installation and connection
in a headend base unit
Notes
For detailed information on the headend base unit, refer to the corresponding operating instructions.
Before inserting or changing a module, pull the mains plug of the headends basic unit from the socket!
Ground the base plate in order to avoid dangerous overvoltages according to EN 50083-1, EN 6072811:2010 (attention: risk of fire/death).
It is not possible to insert two single modules side by side in the basic unit.
The SKM 1-07 cannot be used in combination with a headend base unit.

2.2 Single operation mode
Before installing modules, the power supply must be switched off. Ground the module acc. to
EN 50083-1, EN 60728-11:2010 in order to avoid dangerous overvoltages (attention: risk of fire/death).
Use the grounding screw attached to the device (see Fig. 2).
In stand-alone mode of the SKM 1-01, the power supply is provided by DC input socket (see Fig. 2). A
separate power supply unit SKZ 5-03 is required for it.

3.1 Preparation
During initial operation and all programming of the modulator module, a monitor must be connected to the
monitoring outputs (see Fig. 4).
3.1.1 Control switch
To control the unit first slide the front panel switch to ON position.
When programming is ready, the front panel switch must be in OFF position. This will prevent accidental
changes to be made while controlling other units

At the bottom of the modulator menu a bar appears after approx. 5 seconds. The bar shows the work
load of the output channel in percent.
Fig. 14:
Work load of the output
channel
The work load depends on the selected output channel (7 or 8 MHz), the DVB-T modulation settings and
the set error correction rate FEC.
Since the data rate changes permanently depending on the content of the image, the rate should not
exceed 90%. Otherwise, image interferences such as mosaic pictures may appear.
If the displayed data rate exceeds 90% change to a channel with a bandwidth of 8 MHz if a 7 MHz
channel was selected previously or increase the modulation rate to 64 QAM.
