1 GENERAL
1.1
Introduction
The MO-480/481 is a broadcast grade DVB-T/T2 modulator available in a
standard 1U high 19" rack case (MO-480) and also in an open frame chassis
(MO-481) that can be used for MFN as well as SFN applications.
The modulator has several Transport Stream and T2-MI inputs in ASI and IP
formats so that it can be easily interfaced with other existing transmission
equipments such as gateways. The modulator can be configured to generate any
of the transmission modes listed in the corresponding DVB-T2 standard
including single and multiple PLP, MISO or SISO. It can also be used for DVB-T
applications.
The modulator inputs consist of an MPEG-2 transport stream (TS) in TS over IP
or DVB-ASI format, a 10 MHz GPS reference and a 1pps GPS reference. The
GPS inputs are for SFN synchronisation purposes. The outputs are DVB-T/T2
signals COFDM-modulated and up-converted to RF.
The interest in DVB-T2 is now increasing with the growing demand for
bandwidth mostly to deliver high definition television programmes. Several
countries already have T2 commercial services, some others are running test
trials and many more are on the planning stage.
Highlights of this product are:
DVB-T and DVB-T2 modulation
MFN and SFN
Single output 30 to 900 MHz
Affordable yet broadcast grade design

2 INSTALATION
2.1
Power Supply
The MO-480 is an equipment powered through the mains for its operation.
The MO-481 is powered through an AC Adapter.
2.1.1 Operation using the Mains Adapter
Connect the MO-480 to the mains through the AC voltage connector located on
the rear panel.
Check if the mains voltage is according to the equipment specifications.
2.1.2 Operation using the AC Adapter
Connect the AC power adapter to the module MO-481 through the power
connector on the rear panel.
Then connect the AC power adapter to the mains via the mains cord. Ensure that
your mains voltage is compatible with the adapter voltage.
2.2
Installation and Start-up
The MO-480 modulator is designed for use as a rack-mounted 19 inches device
(1U chassis). The MO-481 modulator it is in an open frame chassis and can be
used anywhere.
To start-up the MO-480, switch the main switch located in the rear panel to
position I (power on). To start-up the MO-481, just connect the AC adapter to
the mains. After a successfully start up, all LEDs of the MO-480 blink (except
power). When the equipment is connected to the mains, the POWER LED
remains lit.
