11 Description
The PolyCompact headend station SPM 2000 LAN, newly designed of Polytron, is a compact, modular channel pro-
cessing device for small and medium-sized communal installations and offers a variety of advantages.
These are:
¾
compact design,
¾
simple operability,
¾
LAN port,
¾
flexible by different modules,
¾
high output level,
¾
continuous output frequency range,
¾
test output (-20 dB)
Dependent on the inserted module the digital DVB standards DVB-C/DVB-T or the analogue TV standards B/G, B/B,
D/K, I, M/N, L can be adjusted.
The PolyCompact SPM 2000 LAN makes a high-quality and economically effective processing of TV and radio
channels possible.
The base unit has 10 slots and can prepare up to 40 channels (by Quattro modulators).
For all reception possibilities of satellites and terrestrial signals (digital and analogous) as well as for the feeding and
modulation of video and audio signals, corresponding modules are available in the Polytron-delivering program. The
power supply, a programming unit for the individual receipt modules as well as an output collecting field is integrated
into the base unit. The also integrated broadband amplifier provides an output level of maximum 100 dBμV.
Several base units can be combined without problems, if required. In this way also larger receiving systems can be
realized. The housing of the headend station is designed for installation into 19"-cabinets or alternatively for wall as-
sembly.
ATTENTION
It has to be taken care at the installation of the headend station that the ventilation slots at the top and base remain
free. Covering these slots can lead to a heat build-up and thereby damage the headend or individual modules.
Î
"Power Overload"
display: The current consumption of each individual module is measured.
If there are too many modules in the base unit, the maximum possible power supply of the built-in power supply
unit is exceeded. In this case, the display will show
"Power Overload"
.
12 Programming
The buttons , , and (Figure 8) are used for the selection and confirmation of the operating steps and
for adjusting the values.
After switching on (connecting to the mains) the SPM 2000 LAN, data will be imported and configured.
This procedure can last up to 40 seconds.
