Important safety instructions

General installation conditions
• Before handling or connecting the equipment, please read this
manual.
• In order to reduce the risk of fire or electric shock, do not expose the
equipment to rain or moisture.
• Do not take the cover off the equipment without disconnecting it
from the mains.
• Do not obstruct the equipment's ventilation system.
• Please allow air circulation around the equipment.
• The equipment must not come into contact with water or even be
splashed by liquids. Do not place containers with water on or near the
equipment if it is not adequately protected.
• Do not place the equipment near sources of heat or in excessively
moisture conditions.
• Do not place the equipment where it may be affected by strong
vibrations or knocks.
• This symbol indicates that the equipment complies with
the requirements of CE mark.

* The unit's consumption with CAM will depend on the type of CAM being used. For the LNB it is considered a standard consumption of 250mA.
- The Power Supply Unit is able to powering up to seven DVBS2-QAM CI modules maximum.
- Is necessary to use both PSU outputs when consumption of one of them exceeds 4A (maximum current in each output).
- The technical characteristics described are defined for a maximum ambient temperature of 45°C (113ºF). Forced ventilation is used for higher temperatures.

Introduction
The DVBS2 transmodulator with QAM CI receives a satellite transponder
in some DVBS (QPSK) or DVBS2 (QPSK or 8PSK) modulation formats and
demodulates it by obtaining an MPEG-2 transport package.
The MPEG2 transport package is then modulated in QAM format and
converted to the output channel (UHF or VHF and with a maximum
bandwidth of 8 MHz) using an agile up-converter.
Additionally, it incorporates a Common Interface slot for inserting a
conditional access module (CAM) to permit the unscrambling of services.
The programming of the transmodulator operating parameters (input
frequency, output channel, modulation format and adaptation of services
mainly) is performed through the universal programmer (ref. 7234).
