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.

* Power consumption is measured with input signal.
The power consumption indicated for CAM and LNB are highest; in any case, depend on the type of CAM and LNB for each facility.
The technical specifications are defined for an ambient temperature of 45 ° C (113 ° F). For higher temperatures forced ventilation will be used.

Introduction
The multiplexer can demodulate up to three DVBT or DVBT2 signals from one
or two satellite IF inputs.
The user selects which services will be transmodulated in each of the two
available output channels. Two transport stream are created, which are then
modulated in QAM (565201) or COFDM (565101) format and converted to
their respective output channels using an agile up-converter.
A Common Interface slot is available. A conditional access module (CAM) can
be inserted to descramble output services.
To configure the multiplexer operating parameters (input frequency, output
channels, modulation formats and adaptation of services) the universal
programming unit (ref. 7234) or the TSuite software can be used.
