HDR-108/HDR-104/HDR-102 Diversity Receivers
MANUAL V9.8 7
Important Notes
 HDR series are MPEG2/H.264 4:2:2 – 10 bits – DVB-T2/T/ and ISDB-T
with up to 8 diversities Receivers, these Receivers are fully compatible
with the DVB-T2 standard included in ETSI EN30075, with DVB-T
standard included in European Standard ETSI EN300744 and ISDB-T
included in ARIB STD-B31 standard.
 The complete Receiver system consists of two parts: firstly, there are
one or more down-converters, which are installed outdoors next to the
Receiver antennas and secondly, the HDR series Receiver which
demodulates the IF delivered by the down converter.
 These Receivers are commonly used with SVP DC down converters,
which are available from 1.3 to 10.5 GHz in different frequency bands.
 On the Receiver site it is important to determine if the channel in which
the transmission will be done has interference, if any other transmission
is being done in that channel.
 While the equipment is being installed, the power supply of the down-
converters should be disabled in the Setup Configuration menu in order
to avoid the risk of short circuits.
 If Celflex 1/2 coaxial cables are used, the maximum length is 150 m. On
the other hand, if RG-214 coaxial cables are used, the maximum length
is limited to 100m.
 The Receiver must be well ventilated. Some space must be left next to
the sides of the Receiver for ventilation purposes. This is especially
important when it is installed in a rack case.
 Special care should be taken with SDI cables. Quality and length are
very important especially with HD-SDI or 3G-SDI signals.
 If the user wants to install the rack mount demodulator unit horizontally,
guides should be used, due to the weight of the equipment.
 It is not advisable to use a power supply lead with a cross-section less
than that of the lead supplied, since this would cause a drop in the supply
voltage and a deficiency in the operation of the equipment.
 Only authorized personnel should open the unit. Any repair or warranty
will be invalidated if the seals are broken.
