3 About this Manual
This manual describes the operation of domo SOLO2 and SOLO4
digital wireless systems. The manual is divided into three main
sections.
Getting started and basic operation
This section describes to users how to deploy and use a domo SOLO
system.
Advanced operation
This section describes the operation of the system in more detail,
concentrating particularly on how to store and recall configurations, with
use of the PC Controller Application.
Technical reference
This section provides technical specification and control protocol data
and will be of interest to those integrating the SOLO system into larger
systems.

4 Introduction
The domo SOLO4 and SOLO2 product range enables the user to build
wireless digital microwave video systems. The domo SOLO4 and
SOLO2 products have been designed to provide rugged point-to-point
links for high quality full frame rate video, and audio, even in non line of
sight and urban environments.
Existing analogue systems suffer from impairments such as video noise,
loss of colour information and poor image quality when line of sight
cannot be maintained, and solutions based on wireless internet
standards and PC platforms deliver poor quality video.
The domo SOLO4 and SOLO2 system is a digital system that uses the
COFDM modulation technique, which effectively eliminates the
problems caused by multipath and reflections.
The SOLO product range allows law enforcement, surveillance and
emergency service communities to now receive the highest quality
video images, in real time, direct from personnel, buildings and vehicles.
The domo SOLO2 system employs the DVB-T 2K carrier COFDM
technology.
The domo SOLO4 system employs a revolutionary narrow band
2.5MHz COFDM technology which demonstrates better propagation for
longer range links, and extra bandwidth efficiency. The domo SOLO4
system can also be upgraded to include a 1.25MHz COFDM modulation
and MPEG4 compression for excellent range performance.
The domo SOLO4 and SOLO2 systems employ common transmitter
and receiver hardware.
The SOLO4 and SOLO2 transmitter is a lightweight, low-power
transmitter suitable for body-worn applications where size, weight and
power consumption are at a premium.
For longer range applications such as vehicle transmissions, the
SOLO4 or SOLO2 transmitter can be upgraded with the use of a
booster amplifier.
The SOLO4 and SOLO2 receivers are diversity input receivers with
extensive built in spectrum analysis tools. The receivers can be fitted
with an optional NETSTREAM card, which then gives the option of
streaming the received video onwards over IP networks.
IMPORTANT NOTE
The SOLO4 and SOLO2 product range has been specifically designed for government
security and law enforcement users, the equipment will tune across frequencies that are
only available to licensed government users. Non-government users should employ the
equipment restricted to the license exempt bands only typically 1.389 to 1.399GHz, 2.400
to 2.483GHz and 5.725 to 5.875GHz

5 Warranty and Support
5.1 Warranty Cover
domo offers a 12 month standard product warranty. During this period,
should the customer encounter a fault with the equipment we
recommend the following course of action:
Check the support section of the website for information on that product
and any software/firmware upgrades. If fault persists;
Call our support line and report the fault. If fault persists and you are
informed to return the product please obtain an RMA number from the
domo support department, and ship the equipment with the RMA
number displayed and a description of the fault. Please email the
support section the airway bill/consignment number for tracking
purposes.
If you have extended warranty provisions then domo will send an
immediate advance replacement to you. Under most circumstances
this must be returned once the fault item is repaired.
Depending on the nature of the fault domo endeavor to repair the
equipment and return it to the customer within 14 days of the item
arriving at our workshops.
Obviously it is impossible to cater for all types of faults and to manage
100% replacement part availability, and delays are sometimes
inevitable. This is why domo recommend that its customers take out an
extended warranty (which includes advanced replacement of faulty
items), and/or hold a basic level of spare parts, which can be held by
domo on the customer’s behalf.
Please contact domo for details of packages that can be tailored to meet
your individual needs, whether they are service availability, technical
training, local geographic support or dedicated spares holdings.

Note. It is recommended that the antennas be connected directly to the transmitter unit.
The use of RF cables at this point will degrade the performance of the system.
The optimum choice of antenna will vary according to application. The
following table gives some suggestions for suitable transmit antennas
with the associated domo part number.

Application Antenna model number
Mobile body worn application 1.00 to 1.40GHz - ANTBCL
2.28 to 2.50GHz - ANTBCS
Mobile vehicle application 1.00 to 1.40GHz – ANT4L
2.28 to 2.50GHz - ANT4S
4.80 to 5.15GHz – ANT6C
Long range point to point link 1.00 to 1.40GHz – ANT12L
2.28 to 2.50GHz – ANT12S
Note. When using antenna types ANT4L, ANT4S, ANT6C, ANT12L and ANT12S
with domo transmitters SMA to TNC adaptor connectors will be needed.
Other antennas for more specialist applications, such as aircraft use or
covert surveillance use are available on request from domo.
Control Cable
The control cable is used for connecting the transmitter unit to a PC
when using the domo PC control application. The PC control
application is described in more detail the Advanced Operation section
of this handbook.
Installation Notes
The domo transmitter has been designed specifically for body worn
applications; however it is a general-purpose wireless video transmitter
and can be used in many applications including the following.
Body worn portable applications
Vehicle based applications
This section gives guidelines for how to install the transmitter in the
above applications.
1
0
Body Worn Applications
Body worn applications will either be covert or overt and this will dictate
the style of antennas and mounting of cameras. For overt applications
domo can supply a harness as shown below (domo part number
ACCBCH)
With all body worn systems the antenna should be selected to transmit
power away from body and domo recommends the use of the domo
body worn antenna (part numbers ANTBCL and ANTBCS).
Experimentation has shown that unlike traditional analogue systems,
front and rear antennas are not normally required. The nature of
COFDM and its immunity to reflections will ensure that the signal
normally bounces back to the receive site even when the operators
body is between the transmit and receive antenna.
In covert applications, ultra slim patch antennas can be used. domo
does not supply patch antennas directly, but can recommend
manufacturers on request.
The SOLO4 and SOLO2 transmitter has been successfully tested with a
wide variety of standard and pinhole cameras. domo does not supply
cameras, but can recommend suitable cameras and suppliers on
request.
The domo transmitter will become warm to the touch after prolonged
operation, and so insulation between the operators’ body and the
transmitter unit should be considered.
The SOLO2/SOLO4 transmitter is splash resistant, but is not
waterproof, so it should not be exposed to moisture for prolonged
periods.
2
Vehicle Applications
Typically, in vehicle applications, a greater range is required than with
body worn applications, therefore the use of additional power amplifiers
must be considered.
domo offers a range of power amplifiers. Interconnection between the
transmitter and any power amplifier should be kept as short as possible,
but where this is not possible, special attention should be taken to use
only low loss cables. An appropriate cable might be RG213C/U. It is
essential to minimise the distance between the amplifier and the
antenna.
Mounting of the transmitter should use the mounting holes provided.
The transmitter is equipped with a self-regulating 5.9 to 16V input that
can be connected directly to the vehicle battery. Power conversion will
be required for 24V vehicles.
The video input can be connected across long video cable lengths so
remotely mounted cameras should pose no problem.
The transmitter is splash resistant, but is not waterproof, so it should not
be exposed to moisture for prolonged periods. The transmitter is selfcooling; however it should be mounted in a ventilated environment.
Forced air cooling is not required.

L-Band and S-Band
Barrel down-converter
The Solo4 Receiver must be configured with the correct down-converter
Local Oscillator (LO) Frequency and down-converter LO side. These
numbers are specific to the type and frequency band of the downconverter.
The SOLO4 downconverter converts the received signal from
microwave frequencies to UHF frequency and applies gain allowing the
signal to run down cables without loss. This down-conversion allows
the domo SOLO Receiver to be mounted remotely from the receive
antennas. The down-converter is available as either a standard nominal
9dB gain model (DCB) or high gain variant (DCBX) nominal 19dB gain.

Diversity, Antenna Positioning and Use of Down Converters
Note: Domo down converters can be damaged by static electricity discharge when
connecting antennas. It is suggested that only antennas with built in DC path to ground
are employed to avoid static damage. If this can not be achieved then antennas should be
shorted to ground before connection to the down converter.
The domo SOLO2/SOLO4 receiver is a diversity receiver and will give
optimum results only when two antennas are deployed. The downconverter boxes should be connected to the receiver, by connecting the
3m TNC cables supplied between the down converter connector
labelled ‘RX / IF OUT’ and the receiver connector labeled ‘IF IN’. Care
should be taken not to over tighten the TNC connectors.
The down-converters convert the RF signal down from microwave
frequencies to the UHF band, which allows the signals to be run along
longer cables without degradation. In the case of the standard domo
SOLO receiver 3 metre long cables are provided, allowing the downconverters to be positioned remotely from the receiver.
It is important that the down-converter be positioned very close to the
antenna - long cables should not be used between the antenna and the
down converter because this can degrade system performance.
Typically antennas and down converters will be positioned outside,
usually on the roof of a building or a vehicle. The down-converters can
be located outside, because they are weather proof. However the
receiver is not weather proof and the 3 metre cables should be used to
allow the receiver to be positioned in an equipment room, rack or
housing.
The domo SOLO2/SOLO4 receiver uses an advanced diversity
technique called maximum ratio combining to construct a good
spectrum from two potentially damaged received signals. To get the
best results from diversity, the antennas should be physically separated
by at least 100cm.
Sometimes better results can be achieved by separating the antennas
further, or by positioning them of different corners of a building. The
optimum antenna placement depends on the environment in which the
equipment is used and the signal path, and is often limited by physical
factors (accessibility for example).
The domo SOLO2/SOLO4 receiver is supplied without antennas since
the optimum choice of antenna will depend on the operational scenario.
For short range or mobile applications, omni directional antennas such
as ANT4L, ANT6C or ANT4S will be most suitable whereas for longer
range fixed links, or where mobile transmit activity is happening in a
defined 120 degree arc the higher gain ANT12L or ANT12S will be
more suitable.
Antennas should be screwed directly to the TNC input of the down
converter labeled ‘ANT/RF IN’.

Control Cable
The control cable is used for connecting the SOLO receiver to a PC
when using the domo PC control application. The PC control
application is described in more detail the Advanced Operation section
of this handbook.
Data Connection
The SOLO receiver features a general purpose DATA port used for
outputting RS232 data transmitted from a SOLO2/4 transmitter.
Installation Notes
The domo SOLO receiver has been designed so that the downconverter units are mounted remotely from the receiver unit, and
connected via the 3 metre TNC cable.
The down-converter units should be connected directly to the receive
antenna, but where this is not possible a short length of low loss RF
cable such RG213C/U should be used. System performance will be
degraded by the introduction of RF losses at this point.
The down converter should be screwed or strapped to a flat surface or
pole, using the integral mounting holes on the unit. The down converter
is weather proof, and has no special cooling requirements. If the downconverter is mounted where it is exposed to the weather then the
connector labelled ‘ANT / IN’ should face upwards.
The antenna itself should be separately secured, the TNC connectors
should not be expected to take the strain of the antenna.
The domo SOLO2/SOLO4 receiver is designed to be mounted in an
equipment rack or shelter and must not be exposed to the elements.
The receiver is splash resistant, but is not waterproof, so it should not be
exposed to moisture for prolonged periods.
The receiver is self-cooling; however it should be mounted in a
ventilated environment. Forced air cooling is not required. Adequate
clearance on either side the receiver (5cm) should be allowed for
ventilation.
The receiver is supplied with a mounting plate that allows the unit to be
screwed or strapped to a flat surface.

7.4 Powering on the System
All external connection to the SOLO2/SOLO4 products should be made,
as described in the previous sections, before proceeding to power on
the system.
Applying power to the Solo Receiver
On powering the SOLO2/SOLO4 receiver, one of the eight green
configuration LEDs on the control panel will light (which one depends on
which configuration was active when the receiver was switched off).
The red Alarm LED may light if the receiver is unable to lock to a signal.
Applying power to the transmitter
When powering the transmitter directly from a 12V source, or from a
connected battery, the following will be observed.
If none of the LEDs on the control panel light then the transmitter may
be in standby mode. If this is the case then press, and hold the RF
button for more than one second.
One of the eight green configuration LEDs on the control panel will light
(which one depends on which configuration was active when the
receiver was switched off).
The alarm LED may be lit, typically if there is no active video source.
Switch On RF on the transmitter
On the transmitter unit control panel, press the RF button briefly until the
RF LED lights. This indicates that the RF output is active, and that the
unit is transmitting.
If the receiver is able to receive the transmitted signal, the receiver RF
LED will light indicating receiver lock, and the receiver ALARM LED
should go out.
Video and audio signals will be presented automatically at the receiver
outputs.
Changing Configuration
domo SOLO2/SOLO4 equipment features eight user selectable and
programmable configurations. By default, all 8 configurations are set to
the values which are listed in Section 16, Default Configurations. The
nfiguration that is currently active is indicated by which of the eight
co
configuration LEDs is lit on the control panel. Pressing the ‘CONFIG
button on the control panel of any domo SOLO equipment will select the
next configuration in order.
On the SOLO transmitters, changing a configuration turns off the RF
output to prevent accidental transmission and potential interference. The
RF output must manually be re enabled once the user is confident that
the correct configuration has been selected.
Modifying the default configurations is done from the PC control
application, as described in the section on Advanced Operation.
31
2
Standby
Any of the SOLO2/SOLO4 transmitters can be placed in a low current
consumption standby mode by pressing and holding the RF button for
one second. The LEDs will go out indicating that the unit is in standby
mode.
Pressing and holding the RF button for one second brings the unit back
out of standby mode.
Diagnostic On Screen Display
The SOLO2/SOLO4 Receiver is equipped with a diagnostic on screen
display. This facility will ‘burn’ diagnostic data onto the video output for
test and set-up purposes. Pressing the RF button will enable this facility
and a diagnostic screen will appear in the video as shown below.
The displayed diagnostic data includes a spectrum display, signal to
noise data, input power level and frequency. The received spectrum
display is useful when checking for interference signals, the SNR
indicated signal quality. For more information on use of this facility a
domo training course is recommended and more information is available
in section 13 of this manual.
Using the OSD as a Set-up / Diagnostic Tool
The On Screen Display (OSD) is an extremely useful tool for system
set-up and diagnostic.
When setting a domo system up the OSD should be used in the
following way.
Check Channel is Clear
With the transmitter OFF, check that the channel is empty of
interference signals, this is confirmed by ensuring that the reported
power in the channel is at –99dBm and that the spectrum is shown as a
rounded dome with no obvious spikes or tones.
Check Quality of Link
Switch on the transmitter and confirm that SNR is 6 or greater and that
power level is at least –92dBm or greater. This represents
3

approximately a 5dB margin. Failure of the link will occur when the
A
power level reaches –97dBm or the SNR reaches 2dBm

7.5 Domo Batteries and Battery Charging
Although domo equipment can be powered directly from user 12V
batteries, domo also supplies a rechargeable battery pack. The
following domo battery items are described in this section.
SOLBAT: 7.2V 4AH rechargeable NiMH battery pack.
SOLBCH: Battery Charger
SOLBCC: Adaptor cable that allows SOLBAT to connect to SOL2/SOL4
TX.

Using the SOLBAT
The domo SOLBAT is used for powering domo transmitters.
The domo SOLOBAT can not be connected directly to the SOL2/SOL4
Transmitter, instead it must be connected using the SOLBCC adaptor
cable. The SOLBCC adaptor cable provides an interface between the 4
pin DC In Lemo on the transmitter and the 6 pin DC Out Lemo on the
battery. The cable is shown below.
When connected a fully charger SOLBAT will power the transmitter for
more than 4 hours.
Charging the SOLBAT
The SOLBAT can be recharged by connecting it to the SOLBCH battery
charger. The SOLBAT battery can be connected directly to the
SOLBCH battery charger, the interface cable is not required. When
connected the SOLBAT indicator LED has the following meaning.
LED Yellow: Battery not connected.
LED Orange: Battery fast charging.
LED Green / Yellow flash: Battery ‘Top Off’ final charging
LED Green: Charging Complete / trickle charging
LED Orange / Green flash: Error
Approximately 2 hours should be allowed for a full charge of the
SOLBAT battery.

The assembled system is shown below.
DC Power and Control Cable
The SOLAMP is powered by the SOL2/SOL4 TX and no additional
power is required. However the voltage range when using the SOLAMP
is more limited.
Antennas
Input Voltage Range: 11-16V, reverse voltage protected.
Current Draw 1.2A (Includes SOL2/SOL4 TX) at 12V.
Domo SOLAMP is supplied without antennas as standard. It is good
practice to ensure that an antenna is always connected before powering
the device. Prolonged operation without an antenna is not
recommended. The antenna should be connected by screwing it to the
TNC Type output connector with adapters as required, but care should
be taken not to over-tighten.
Note: It Is recommended that where possible antennas should be connected
directly to the SOLAMP. Use of cables will degrade performance.

Installation Notes
The domo SOLAMP has been designed specifically for vehicle
applications, however it is a general-purpose amplifier and can be used
in many applications including the following.
Vehicle applications
Aircraft applications
Long Range fixed links
Interconnection between the SOLAMP transmitter and the antenna, or
any intermediate optional power amplifier should be kept as short as
possible. Special attention should be taken to use only low loss cables.
An appropriate cable might be RG213C/U. It is essential to minimise the
distance between any amplifier and the antenna.
The SOLAMP is equipped with a self-regulating 12V input that can be
connected directly to the vehicle battery. Power conversion will be
required for 24V vehicles or 28V aircraft systems.
The SOLAMP is splash resistant, but is NOT waterproof, so it should not
be exposed to moisture for prolonged periods. The SOLAMP is selfcooling; however it should be mounted in a ventilated environment.
7.7 Using the booster 5W Amp
Additional range can be achieved by connecting the AMP5W-xxxxxx
booster amplifier to the domo SOLO2/SOLO4 transmitter.
Connections
This section describes how to connect the following model numbers.
AMP5W-120140
AMP5W-230250
The domo AMP5W-xxxxxx is supplied with the following cables:
RF Cable
DC Power Cable

RF Connection
The domo AMP5W has the following input power requirements.
AMP5W-120140: Input Power 100mW or 20dBm
AMP5W-230250: Input Power 10mW or 10dBm
Therefore care must be taken when connecting the AMP5W-230250
product to either SOLO2 or SOLO4 transmitter. The output power of
the transmitter will need to be reduced when connecting to the AMP5W230250 amplifier, this can be done using the built in digital attenuator
using the PC Software GUI, or by fitting an RF attenuator in line.
Ideally when balancing the 5W Amplifier and domo transmitter a power
meter should be employed, this will give best results, because cable
losses can be factored.

8 Advanced Operation
8.1 SOLO System PC Controller Application Software
Advanced control of the SOLO2/SOLO4 system is available by using
PC control applications.
Typically users may want to customize the default configurations to
control settings such as frequency, scrambling keys, modulation
parameters, and video resolution.
The SOLO2 and SOLO4 transmitter products are controlled by the
solo_tx_ctrl.exe application available on the CD delivered with the
product.
The SOLO2 and SOLO4 receiver is controlled by the solo_rx_ctrl.exe
application available on the CD delivered with the product.
Note that exact file names may change as software version information is a part of domo
file names.
A PC is required with two RS232 Serial COM ports to control both a
transmitter and receiver simultaneously. Where changes are to be made
to either a transmitter, or a receiver, at different times, a PC with a single
RS232 Serial COM part can be used.
Installation of the two control programs is as simple as copying them
from the CD to a suitable location on the PC. No install shield routine is
launched. Note that the controllers generate their own log and
initialisation files, so it is best to create a dedicated directory for these
applications, perhaps with links to the applications from the desktop of
the PC.
Use the supplied cables to connect the chosen COM port(s) of the PC
to unit(s) to be configured.
Launch each application in turn by double clicking or using the run
command.
Connection with a SOLO product should be automatic, but the user can
force selection of the correct COM port using the drop down, followed by
the “Connect” button.
Errors such as the following may appear during the connection process
if the PC is unable to automatically ascertain which unit is connected to
which COM port.
Error attempting to read invalid address
Error has occurred during polling, polling has been disabled
41
2
For both controllers, changes can be made to the unit configuration
using the drop down and data entry fields.
Changes are only applied to the unit when the “Apply” button is clicked.
Current values, as running in the unit, can be read using the “Refresh”
button.
Parameters that are status information only appear in greyed in the
application.
Further engineering and configuration controls can be found within the
“Options” and “File” drop down menus in the application title bars.

Narrow Band FEC
This option applies to SOLO4 transmitters only. The default FEC is 2/3,
however improved range operation can be achieved by selecting FEC
1/3. FEC 1/3 will improve signal range by 3dB. However FEC 1/3
reduces link capacity to 1.2Mb/s therefore reducing picture quality.
FEC Link Bitrate Sensitivity

Narrow Band Guard Interval
This option applies to SOLO4 transmitters only. The Guard Interval
defaults to 1/16. Interval 1/8 is also available for very long range
(aircraft downlinks) applications.
Narrow Band Modulation
This option applies to SOLO4 transmitters only. The COFDM mode can
be changed between QPSK and 16QAM. QPSK is the default mode
and will give the strongest most rugged RF link performance. Selecting
16QAM reduces the link performance by 5dB but improves the link data
throughput, giving significantly better video quality.
Note: The terminology DVB-T refers to the 8,7,6MHz wide bandwidth modulation
employed in the SOLO2 products. The SOLO4 product is also capable of DVB-T, but this
mode is not recommended for normal operation
DVB-T Service Name
Applicable in DVB-T mode only, defaults to Unit 1. This should not be
changed in normal operation
DVB-T FEC
Applicable in DVB-T mode only, the default FEC is ½. Other FEC rates
will all reduce the range of the product, but will improve image quality
and capacity of the link.

DVB-T Guard Interval
Applicable in DVB-T mode only. The Guard Interval defaults to 1/32.
Other guard intervals such as 1/16 or 1/8 are available for very long

DVB-T Modulation
Applicable in DVB-T mode only, the COFDM mode can be changed
between QPSK, 16QAM and 64QAM. QPSK is the default mode and
will give the strongest most rugged RF link performance. Selecting
16QAM reduces the link performance by 5dB but improves the link data
throughput, giving significantly better video quality.
Output Attenuation
This control can be used to make minor adjustments to the output
power level, but in normal operation should be disregarded.
Video Input
This control is used to select the composite video input standard.
Options are PAL, and NTSC both with and without 7.5 IRE pedestal.
MPEG Mode
The default encoding mode is MPEG2, however for SOLO4 products if
the Ultra Narrow Band upgrade has been purchased, then MPEG4 will
also be available. It is recommended that MPEG4 be employed when
the unit is operating at low bitrates (2.5MHz bandwidth FEC1/3 or
1.25MHz bandwidth FEC1/3).
MPEG2 GOP Length
By default MPEG2 GOP length is set to a low delay stripe refresh mode.
This option allows the user to set the GOP length for a standard GOP
structure at the expensive of an additional delay.
MPEG4 Encoding Mode
This option is only available on SOLO4 products installed with the Ultra
Narrow Band Upgrade. This defaults to low delay interlace. Other
modes are available but advice should be sought from domo before
selection.
MPEG4 Frame Rate
This option is only available on SOLO4 products installed with the Ultra
Narrow Band Upgrade. This option allows the user to select lower
frame rate encoding (1/2 frame rate, ¼, 1/8 etc) It is recommended that
4
8
MPEG4 reduced frame rates be employed when the unit is operating at
low bitrates (1.25MHz bandwidth FEC1/3).
Video Bitrate
This control can be used to set the video bitrate within the constraints of
capacity available in the channel, but only when “Chaining Input” is set
to ON.
For normal SOLO transmitters, chaining CANNOT be enabled, and as
such video bit rate control is automatic.
The video bit rate is automatically maximised in each configuration
when “Chaining Input” is turned off.
Horizontal resolution
The video coding resolution can be selected from 704, 528, 480 and
352 pixels. Changing the horizontal resolution to lower values will make
the coded picture softer.
Care should be taken to match the horizontal resolution to the resolution
of the camera connected to the transmitter; this will give best image
results.
Audio Encoder
The Audio can be turned on and off with this control. Audio is OFF by
default, but there are several audio modes that vary from very high
quality to speech grade that can be selected with this control. Enabling
audio will degrade the video quality, because some of the available data
capacity is diverted away from video to audio. Selecting high fidelity
audio modes will degrade the video quality more than lower fidelity
audio modes. The Audio encoder can also be switched to 32 kHz and
48 kHz MPEG Layer 1 modes; from software V3.3 upwards.
Note: The Solo4 receiver only supports 48 kHz sampling in MPEG Audio mode
and bit-rates in the range 192 to 448kbits/s.
Audio Input Level
This control is used to define the audio gain to be applied to the audio
input signal. 0dB is used for line level audio and various options up to
48dB of gain can be applied for microphone inputs.
Unit Name
This field allows the user to enter an identifier for the service that they
wish to transmit. This must match that selected at the receiver for the
service to be decoded. The unit name can be constructed of any eight
ASCII characters.

Sleep Mode
This control allows the unit to be forced into a Sleep Mode where main
functions are disabled, and the power consumption is significantly
reduced.
Data
With this ON / OFF control the user can select whether the transmitter
passes serial RS232 data across the RF link to the receiver.
Data Baud Rate
This field is used to select the baud rate of any RS232 serial data
component to be passed from the transmitter to the receiver across the
RF link.
Chaining Input
This control is not used in current SOLO products.
Chain Number
Current Config
Scrambling
This control is not used in current SOLO products.
This field reports the last loaded configuration number. Note that for the
SOLO transmitter, changes applied after the configuration has been
loaded are saved immediately into the current configuration.
If the AES scrambling option has been purchased for the SOLO2 or
SOLO4 system in use, then it is possible to encrypt the link. Scrambling
must be enabled at the transmitter by selecting either AES128 or AES
256 in the scrambling field. At this point the user will need to ensure that
the correct key is in use and this is done by using Options / Write AES
Key.
The key is a 128bit key for AES128 and a 256bit key for AES256 and is
entered as either 32 or 64 ASCII hexadecimal characters (0..F).
Video Locked (Status Only)
This status information indicated whether the transmitter is successfully
locked to the incoming composite video signal. Unlocked status may
indicate cabling faults, or poor quality incoming video feeds to the unit.

connected downconverters.
For domo supplied downconverters, this should be set as follows:
1880MHz for S band transmissions (2.28 to 2.55GHz)
1700MHz for L band transmissions (1.15 to 1.4GHz).
Down converter LO side
This field allows definition of the local oscillator side.
For domo supplied downconverters, this should be set as follows:
LOW for S band transmissions (2.28 to 2.55GHz)
HIGH for L band transmissions (2.28 to 2.55GHz)
OFDM Bandwidth
This field displays the width of the received OFDM signal and should be
set to 2.5MHz for normal SOLO4 system operation, and should be set
to 8MHz for normal SOLO2 system operation.
OFDM Guard Interval
In this field the user selects the guard interval which matches the
transmitter. For SOLO4 systems typically a guard interval of 1/16 is
used, however on very long range transmissions a guard interval of 1/8
may be employed. For SOLO3 systems typically a guard interval of
1/32 is used, however on very long range transmissions a guard interval
of 1/8 may be employed.
OFDM Mode (Status Only)
This field displays the COFDM constellation that is being demodulated
at the receiver. In normal operation this will match that selected at the
transmitter.

BER Pre Viterbi (Status Only)
This figure is for engineering use and gives a representation of the error
rate prior to the error correction techniques having been applied in the
receiver.
BER Post Viterbi (Status Only)
This figure gives a measure of the bit error rate after error correction
techniques have been applied in the receiver. Any numbers greater than
0 in this field indicate the presence of un-correctable errors in the
received stream, and thus picture glitching and audio artefacts will
occur.
Input Level (Status Only)
This figure indicates the received signal level at the two receiver inputs.
Normal Operation will occur when the input level is between –15 and –
90 dBm. Signals greater than –15 may be too powerful and cause
damage. Signal less than –90dBm may be too weak and cause picture
loss (typical link failure will occur between –95 and –99dBm).

Descrambling
If the AES scrambling option has been purchased for the SOLO system
in use, then it is possible to encrypt the link. Descrambling must also be
enabled at the receiver by selecting AES128 or AES256 in the
descrambling field. At this point the user will need to ensure that the
correct key is in use at the receiver and this is done by selecting
Options / Write AES Key in the receiver controller.
The key is a 128bit value for AES128 and a 256bit value for AES256,
and is entered as 32 or 64 ASCII hexadecimal characters (0...F).
Decoder Lock Status (Status Only)
This field reports whether the video decoder is successfully locked to the
incoming digital bit stream.
Current Config
This field allows the user to select which of the 8 memory configs the

Chaining
Chaining allows multiple services to be sent via one RF link. A receiver
may be connected to a transmitter to form a chaining or relay link. To
allow this, the chaining interfaces provided on the first receiver must be
connected to the second transmitter. Three modes of operation are
supported - no chaining (default), chaining mode, and relay mode. The
chaining mode allows two services (remote and local) to be combined.
The relay mode allows just the remote service to be transmitted turning
off the local service.
For chaining mode to operate correctly, the second unit in the chain
must operate at twice the transmit data rate from the first. If the first unit
is operating in QPSK rate 2/3 the second unit must operate in 16QAM
rate 2/3. If the first unit is operating in QPSK rate 1/3 the second unit
must operate in QPSK rate 2/3. The units must have different chaining
numbers selected, and the different unit names. For the relay mode to
operate correctly the second unit must have the transmit rate greater or
equal to the first unit.
Options
Chaining is a licensable feature.
Engineering – provides access to further diagnostic and calibration

9 NETSTREAM IP Output Option
9.1 General Info
This section is relevant only to customers that have the NETSTREAM
option fitted in their SOLO2 or SOLO4 receiver.
The NETSTREAM can only be fitted in box style 2.
The NETSTREAM product features an RJ45 socket for connection to
10 Base T or 100 Base T Ethernet networks. The network interface
automatically switches between 10 Base T and 100 Base T as required.
The connector is wired for straight connection to a network Hub and
does not automatically compensate for Ethernet crossovers. If a direct
connection to a PC is required, then an Ethernet cross over cable
should be used.
9.2 Streamer
The main use for the NETSTREAM card is to allow viewing of the
received video/audio signal on a standard PC (or laptop) running the
domo software decoder software (part number NETSWDR).
Data is transmitted over the Ethernet network by means of “multicasting”
i.e. continuous real-time streaming of packets accessible to any PC
connected to the network.
It is therefore possible for more than once connected PC to view the
streamed data simultaneously.
Two types of multicast IP packets are streamed.
Packets carrying video, audio and data as received by the unit;
Packets known as Session Announcement Protocol and Sessions
Description Protocol data (SAP and SDP), which contain information
regarding the nature and location of the stream itself.
9.3 Web Server
The unit features a web server, which can be used to change the
configuration of the streaming parameters.
The default IP address of the unit when delivered is 192.168.0.71
A standard Internet browser can be used to reach the configuration
page of the unit.
The URL of the configuration page is http://192.168.0.71/index.htm
Note that the address of the index page will change in the instance that the NETSTREAM
IP address is subsequently changed.
