IMPORTANT NOTES:
1. The DR-100 series digital COFDM receiver is completely compatible with
the DVB-T standard included in European Standard ETSI EN300744.
2. There are two different models available: the DR-102 diversity 2 receiver
and the DR-106 diversity 6 receiver. Two down-converters can be
connected to the DR-102 receiver and up to 6 down-converters can be
connected to diversity 6 receiver. Each down-converter is connected to
an independent receiver antenna in order to provide diversity.
3. The complete receiver system consist of two parts: first, the down-
converters installed outdoors next to the receiver antennas and second
the rack control unit DR-102 or DR-106 installed indoors which
demodulates and decodes received incoming signal from the downconverters.
4. DR-100 series receivers usually work with SVP DC-COFDM down-
converters, which are available in bands of 500MHz in the frequency
range from 1.3 to 10.5GHz
5. In the receiver’s site is important to determine if the channel in which
the transmission will be carried out is interfered. In addition, special care
must be taken in 2400 to 2500MHz band, due to the possible presence
of WiFi signals.
6. While installing the equipment, the power supply to the down-converters
should be disabled in the Setup configuration menu of the rack-mount
demodulator unit, to avoid the risk of short-circuits.
7. The receiver system must be well chilled. Some space must be left next
to the sides of the equipment for ventilation purposes. This is especially
important when it is installed in a rack case.
8. If you wish to install the rack-mount demodulator unit horizontally,
guides should be used, due to the weight of the equipment.
9. It is not advisable to use a power lead with a cross section smaller than
that of the lead supplied, sing this would cause a drop in the supply
voltage and deficient operation of the equipment.
10.The front panel of the DR-100 series receivers is automatically locked
when the user stops manipulating the equipment for 30 minutes.
11.Only authorized personnel should open the product and any repair or
warranty will be invalidated is the seals are open.

1 Description
The DR-100 series COFDM digital receivers receive the signal from the
down-converters which are installed outdoors next to the receiver antenna.
It demodulates and decodes incoming signal. Afterward the signal sent by
the transmitter is obtained at its outputs in video, SDI and ASI formats.
Figure 1.1 Connection diagram of the DR-100 series equipments
There are two different models available: the DR-102 diversity 2 receiver
and the DR-106 diversity 6 receiver. Two down-converters can be
connected to the DR-102 receiver and up to 6 down-converters can be
connected to diversity 6 receiver. Each down-converter is connected to an
independent receiver antenna in order to provide diversity. This allows
several different antennas to be installed, in order to take advantage of
their combined characteristics, or several antennas, of similar types or
different types can be installed oriented in different directions to offer wider
coverage. Using a diversity system makes the link more robust and offers
better performance than a non-diversity system.
The complete receiver system consist of two parts: first, the downconverters installed outdoors next to the receiver antennas and second the
rack control unit DR-102 or DR-106 installed indoors which demodulates
and decodes received incoming signal from the down-converters.
DR-100 series receivers usually work with SVP DC-COFDM down-converters,
which are available in bands of 500MHz in the frequency range from 1.3 to
10.5GHz
The diversity technique used in the DR-100series digital COFDM receivers is
known as "Maximum Ratio Combining” (MRC), in which the signal to be
demodulated is the result of combining the best sub-carriers in each signal
delivered by the down-converters; in other words, the unit does not simply
select the input signal from one of the down-converters, it combines these
signals in such a way that the signal used by the demodulator is always the
best signal available.
Chapter 1: Introduction
2
The IF signals delivered by the down-converters are fed into the rack-mount
demodulator, which demodulates them using the MRC diversity technique
and then decodes them to obtain two composite video signals, two SDI
digital signals, four analogue audio signals and four digital audio signals
embedded in the SDI signal. All models of the DR-100 series also have a
DVB-ASI transport stream output that can be extremely useful if several
decoders are to be chained or to implement an intermediate ASI feed
without having to decode it. They also have a Genlock reference input in
order to lock the SDI output signals.
This equipment is capable to receive GPS data or other data types
introduced, at different speeds, in the data channel in SVP transmitters.
The display and the keypad on the front panel of the demodulator
equipment can be used to monitor many parameters of interest, such as the
modulation, the Viterbi coding or the FEC, and the guard interval used
(obtained when the TPS, [Transmission Parameter Signalling] carriers are
demodulated), signal levels, link quality parameters such as the SNR, the
MER and the BER and the presence of alarms and/or warnings.
When steering the antennas, the main screen showing the signal levels and
the SNR of the IF inputs is very helpful. These measurements are displayed
as a bar graph and as numerical values. The numerical values do not
express signal levels or SNR in dB, they are merely indicative. The scale for
the signal levels is from 1 to 100, and the SNR values range from 1 to 10.
These measurements are really useful while orienting the antennas.
There is also a UDP/IP Ethernet link that allows these and many other
parameters to be controlled and monitored from a remote station.
The equipment can be AC mains powered or run off DC batteries. The
switchover from the mains to batteries is automatic. The down-converters
are powered from the demodulator unit via the IF coaxial cable that
connects them together.
The Down-Converters are waterproof and are installed next to the reception
antennas.
An optional flight case is available for the rack-mount demodulator. Its size
is 2 units rack; consequently, two equipments can be transported in it.

1 Introduction
All connectors of the rack-mount demodulator unit are on the rear panel, as
shown in the figure below:
Figure 1.1 Back view of the rack-mount demodulator
On the other hand, the connectors on the down-converter are on both the
top panel and the bottom panel, as shown below:

2 Power supply
The equipment can be powered by an AC source between 90 and 240V, or a
DC source of 11 to 36 V. The down-converters are powered from the rackmount demodulator unit via the IF coaxial cable that connects them
together.
When the equipment is powered by an AC source, this is connected to a
switching power supply that gives a 12V output.
The power-supply board receives either the 12V supply from this power
supply or a DC voltage between 11 and 36V from the DC power input, and
converts the input to the supply voltages required by the equipment:
+3.3V, +5V, +12V and –12V.
The mains frequency should be between 50 and 60 Hz.
The AC mains input uses a Neutrik MLC connector. A cable with the required
connectors is supplied with the equipment.
The AC power connector used in this equipment is designed to prevent
accidental disconnection. To extract the connector, pull back the locking clip
and rotate the connector, as indicated on the connector itself.
It is not advisable to use a power lead with a cross-section less than that of
the lead supplied, since this would cause a drop in the supply voltage and
deficient operation of the equipment.
The DC power supply is connected via a Neutrik 4-pin male XLR connector
with a safety clip to prevent accidental disconnection.
The IF inputs of the demodulator supply +12V to power the downconverters.
3 Video
The DR-100 series receivers include two analogue composite video outputs
and two SDI digital video outputs.
Each of these signals is available on 75Ω insulated BNC connectors located
on the rear panel of the rack-mount demodulator unit.
The SDI digital video outputs are compatible with the SMPTE-259M
standard.
We recommend the use of RG-59 video cable. If this type is not used, we
recommend that the cable used that does not attenuate the high-frequency
components of the video signal. When the cable has been selected, it is
important to determine the length required. For cables longer than 50m, it
is advisable to check the cable and the losses that occur on them.
Chapter 2: Connections
6
It is important that 75Ω connectors be used. This is because the female
output connector of the demodulator unit may be damaged, and because an
impedance mismatch will occur.
4 Audio
The DR-100 series receivers deliver analogue audio signals and digital audio
signals embedded in the SDI signal.
The equipments have four analogue audio outputs, available on 3-pin male
XLR connectors on the rear panel of the rack-mount demodulator unit.
The pinout of the XLR-3 connectors is the following one:
PIN-1: Ground
PIN-2: Hot (+)
PIN-3: Cold (-)
For the output connections of the digital audio signals embedded in the SDI
signal they can be used the same 75Ω insulated BNC connectors that are
used to transport the digital video signals.
The SDI digital video outputs with the four digital audio signals embedded
in each of them are compatible with the SMPTE-272M standard.
5 DVB-ASI
The DR-100 series receivers have a DVB-ASI Transport Stream output,
compatible with the EN50083-9 standard, available on an insulated 75Ω
BNC connector on the rear panel of the rack-mount demodulator unit.
This output may be extremely useful if an intermediate ASI feed is required
without needing to decode the audio and video signals and then recode
them into MPEG-2 in the transmitter equipment.
6 Genlock
The DR-100 receivers have a Genlock external reference input in order to
lock the video and SDI digital outputs to it. The connection is available on a
75Ω insulated BNC connector located on the rear panel of the rack-mount
demodulator unit.
7 Data Out
The DR-100 receiver can get data introduced to the data channel of the SVP
transmitters. The information is available in a DB9 connector in the rear
panel of the rack equipment.
Chapter 2: Connections
7
The receiver can also be controlled remotely via an RS-232 connection.
From the set up menu the user will establish whether the DB9 port will be
used as a data out port or as a remote control port.
8 Remote control
The DR-100 series receivers can be controlled and monitored remotely over
an Ethernet link.
The link is connected via an 8-pin RJ-45 connector with a 10/100 Base-T
network interface. This connector is located on the rear panel of the rackmount demodulator.
9 Down-converter
The connection between the rack-mount demodulator unit and the downconverter uses coaxial cable, whose maximum length depends on the type
of coaxial cable used. If the Celflex ½” coaxial cable is used, the maximum
length is 150m but if the RG-214 coaxial cable is used, the maximum length
is reduced to 75m.
10 Antenna
The antenna is connected to the female N-type connector on the top panel
of the down-converter.
The down-converter can be mounted next to the receiver antenna on a
mast with a maximum diameter of 60mm. This provides a simple, easy
mounting method, as can be seen in the photograph below:
Figure 10.1 Connection of the receiver antenna
Chapter 2: Connections

1 Introduction
The DR-100 series receivers can be controlled and monitored either locally and
remotely (via an Ethernet LAN connection).
The equipment has two main display screens: one of them displays the receiver
frequency, the presence or absence of DVB-ASI MPEG-2 data, the constellation,
the Viterbi coding or FEC, the guard interval and the number of faults or cuts
produced in the link

; the other shows the signal level and SNR of the IF
signal(s) being received by the demodulator.
In the second screen, to monitor the signal levels of the different demodulators,
just press the UP and DOWN buttons. Alternatively, to monitor the signal levels
of all of the demodulators simultaneously, press the LEFT and RIGHT buttons
This second option is extremely useful when adjusting the orientation of the
antennas.
To change from one main screen to the other, press the ENT button. When the
equipment is turned off, the last main screen displayed is memorised. When the
equipment is turned back on, or when the power returns after a power cut, the
display will show the corresponding main screen.
When the user stops manipulating the equipment (when several 30 minutes have
passed since the last order), the equipment is locked and the display shows the
last main screen that was accessed and.

1 Introduction
NetC, Network Controller, is the new equipment control software developed by
SVP Broadcast Microwave. This new software lets the user control multiple SVP
machines simultaneously provided they are connected to the same local area
network.
Remote configuration and monitoring of DR-100/HDR-100 series, DR-70/HDR-70
and DT-70/HDT-70 equipment can be carried out with this new software.
Next, installation and operation of this software is described.
2 Installation
To be able to control remotely SVP machines is necessary to install the software
and then to configure the machines to make possible their communication with
the computer on which the software has been installed.
The control software application is delivered in a CD together with SVP
equipments. This software is also available on our web site:
http://www.svpbm.com/ing/support.htm
. On the web site there will always be
available the latest version of this software.
Installation of this software starts when setup file is selected. Then just follow
installation process.
To control the equipment remotely, the following steps are required:
1. The LED next to the REMOTE button must be lit in green. The REMOTE
button is used to select the remote control mode. When the LED next to
this button is lit in green, the equipment is set for remote control via the
Ethernet link, while if this LED is out, the equipment can only be controlled
locally. To activate o defuse the remote control, simply press this button.
Figure 2.1 Front view of DR-70
2. When the equipment is set for remote control (the REMOTE LED is lit in
green), the Ethernet communications parameters must be configured. Go
to Setup Configuration Menu, enter Ethernet Parameters submenu and set
the following parameters:
Chapter 7: NetC Software to control remotely a network of SVP equipment
39
a. Local IP address: this is the IP address of the SVP machine within
the LAN that it is connected to. This IP address does not have to be
fixed.
b. The IP address of the gateway or router: this is the IP address of
the router in the LAN to which the receiver is connected.
c. The subnet mask: depending on the configuration of this mask and
the remote IP address, packets transmitted by the receiver will
either be transmitted within the LAN or outside the LAN, via the
router.
d. The public IP address of the remote station to which the SVP
machine must connect. This is the IP address of the computer the
software is installed on. This IP address must be fixed.
e. The communications port to be used for communications between
the machine and the remote station. The router in the LAN to which
the remote station is connected must be configured so that packets
sent to this port are routed to the IP address configured in point d.
This completes the definition of the connection between the receiver
and the remote station. This last configuration is set in the router’s
NAT table (Network Address Translation).
3 Software Operation
Once the installation is done, we can proceed with the execution of the software.
The operation of the control software can be divided into two sections: network
configuration and equipment control.

The logbook tab shows the last 32 warnings/alarms. However all the alarms
occurred during the day are stored in a file.
In the directory where NetC software has been installed there is a folder named
logbook. Inside logbook directory there are several folders one for each SVP
equipment on the net. The name of each folder is the text written in Title field
when the machine was added to the network. The file with the logbook
information, alarms and warnings, is stored in the corresponding folder.

1 Introduction
The DR-100 series receivers can be controlled remotely through a RS-232
connection. A DB9 connector is located in the rear panel of the receiver.
The connection between the PC and the receiver has to be configured in order to
be able to remotely control the receiver.
2 Operation
To setup the connection, the user should configure the RS-232 connection
parameters in the Setup Configuration menu of the receiver. Steps to follow are
described below:
1.- Press ENT button to access to the main menu
2.- Using UP and DOWN arrows select Setup Configuration Menu and press ENT
button
3.- Move to line nº 10 Data options and press ENT button
In the submenu following parameters will appear:
1.- Ethernet: This option is currently locked
2.- RS-232: GPS/ Data out/ HyperTerminal
3.- Baud: 2400 – 115200bps. This parameter is locked to 4800bps when GPS
option is selected.
Once RS-232 parameter in the receiver is configured as HyperTerminal, the
receiver will allow the operator to control it remotely from a PC using the
HyperTerminal or a equivalent application. Baud rate should be the same in the
PC application and in the receiver.
The equipment is controlled remotely by a PC. RS-232 connection
Once the connection has been established between the receiver and the
computer in the HyperTerminal main window receiver’s status information will be
displayed.

------------------------------------------
There are several commands used to set or retrieve information from the
receiver. To each command the receiver will answer either with the required
information or with a message confirming that the parameter has been
configured properly.
All the commands that are sent to the receiver should end with the ‘ENTER’ key.
We will refer to it as ‘Enter’.
When the user types a single ‘Enter’ the receiver will respond:
-----------------------------------------“Command Error”
“Help + Enter for instructions”
------------------------------------------
There are several commands that must be typed before pressing ‘Enter’ key.
Each command indicates to the receiver to carry out a concrete action.
By typing ‘Help’ and pressing ‘Enter’ the receiver will display which commands
can be used and how does de operator have to type the instructions and
commands.
-----------------------------------------“Info + Enter”
“System=[on,off] + Enter”
“Frequency=xxxx,x + Enter”
“BandW=[5…8] + Enter”
“PID=[Auto, Manual] + Enter”
