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.

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

5.1
Warranty and Support
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.

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.
19
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.
20
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.

Getting Started with the SOLO Receiver
Connections
This section describes how to connect the following model numbers.

SOL2RX

SOL4RX
The SOLO receiver is normally purchased with Cobham Surveillance down-converters.
There are two versions of Cobham Surveillance domo downconverters; an older square box version and a later Barrel
Down-converter.
The square box variants have product codes DC-XXXXXX.
 DC-100140
 DC-225265
 DC-310340
It is the addition of the down-converters that makes the system
frequency specific.
The SOLO Receiver is supplied with the following components.

Two RF cables, 3m

Video cable 3m

Audio cable 3m

Control cable 3m

AC / DC Power adapter
22
The picture below shows the two types of domo weatherproof down
converter.
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’.
Video Output Connection

LEMO connector on the DC power output. Push the LEMO plug into the
socket labelled ‘12V’, taking care to align the connectors. Connect the
AC adapter block to your local mains electricity supply, noting the mains
supply requirements detailed on the adapter.
The 12V DC input has the following characteristics.
For Box style 1.

Input Voltage Range – 9V to 16V, reverse voltage protected.

Current Draw – 0.9A at 12V
For Box style 2.

Input Voltage Range – 10V to 18V, reverse voltage protected.

Current Draw – 1.0A at 12V
domo can supply optional bare DC power leads, for connection or
hardwiring to other DC sources. The domo part number is CABDC3
29
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.
30
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
configuration that is currently active is indicated by which of the eight
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
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
32
approximately a 5dB margin. Failure of the link will occur when the
power level reaches –97dBm or the SNR reaches 2dBm

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.
33
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:

Using the Clip On 1W Amplifier
Additional range can be achieved by connecting the SOLAMP1W clip
on amplifier to the domo SOLO2/SOLO4 transmitter.
Connections
This section describes how to connect the following model numbers.

SOLAMP1W
The domo SOLAMP1W is supplied with the following cables:

RF Cable (SMA to SMA semi-rigid bridge cable)

DC Power Cable (with Control breakout)

Lemo to Dtype control cable
Amplifier Connection
The domo SOLAMP1W is designed to mount directly onto the
SOL4/SOL2 transmitter. The following steps should be taken.
1. Screw the SOL2/SOL4 transmitter down onto the SOLAMP,
using the 4 screws provided.
2. Connect the RF output of the transmitter (SMA) to the RF input
of the amplifier (SMA) using the short semi rigid SMA cable
provided. The SOLAMP is designed to work directly with the
SOL2/SOL4 transmitter.
3. Using the double-headed 16pin Hirose cable, connect one end
to the transmitter Hirose socket, and the other end to the
amplifier Hirose socket.
4. The 3 pin Lemo spur protruding from the double-headed Hirose
cable breaks out the SOL2/SOL4 transmitter RS232 control
lines. The 3 pin male Lemo to Dtype cable should be
connected here when control of the transmitter from the RS232
PC application is required.
35
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.

Input Voltage Range: 11-16V, reverse voltage protected.

Current Draw 1.2A (Includes SOL2/SOL4 TX) at 12V.
Antennas
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.
36
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
37
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.
38
The amount of attenuation required is shown bellow.
Note the SOL4TXLE-138139 (1.389 to 1.399GHz), SOL4TXLE-240248 (2.4 to 2.483GHz),
SOL2TXLE-138139 (1.389 to 1.399GHz) SOL2TXLE-240248 (2.4 to 2.483GHz)must not
be connected to 5W PA, because these elevated power levels are not permitted in the
license exempt bands.

Advanced Operation
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
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.

supported frequency as appropriate.
The transmit frequency can be set in step sizes of 250kHz.
Modulation Bandwidth
For the SOLO2 transmitter products, the modulation bandwidths 8, 7 or
6MHz can be selected.
For the SOLO4 transmitter products, the modulation bandwidths 8, 7, 6
or 2.5MHz can be selected. If the Ultra Narrow band upgrade has been
purchased the 1.25MHz will also be available to select.
The normal mode of operation is 2.5MHz.
Modulation Output
This control is used to turn on and off the RF output. After a
configuration change, the output always reverts to OFF.
45
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.

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.
46
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
range (aircraft downlinks) applications.
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
47
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.
48
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
This control is not used in current SOLO products.
Current Config
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.
Scrambling
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).

For each IF input, the SNR (Signal to Noise Ratio) is reported. Values in
the order of 18dB to 22dB represent strong received signals, whilst
values in the order of 5dB represent poor received signals which will
likely give rise to decoding errors.
54
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

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.
Chaining is a licensable feature.

NETSTREAM IP Output Option
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.
9.3

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.
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.
59
To access the control page, the user is required to follow a login procedure.
When prompted, enter the following login details:
User Name:
admin
Password:
ipradio
The browser will display the page shown below:
60
IP Address
This control allows the user to change the IP address of the unit. The
factory default value is 192.168.0.71.
The user should make a note of the unit’s new IP address when
changing it. Failure to do so will result in an inability to use the web
browser interface until the unit’s new IP address is recovered.
Multicast Address
This control allows the user to change the multicast address used by the
unit. The default value is 239.16.33.254.
Port Number
This control allows the user to change the multicast port used by the
unit. The default value is 10000.
TTL
This control allows the user to change the value of the IP TTL (Time to
Live) set by the unit.
SAP Address
This control allows the user to change the value SAP/ SDP multicast
address used by the unit. The default value is 224.2.127.254 and the
port used is 9875. These are standard multicast values for such
parameters, and it is recommended they are not changed unless
specifically required due to routing restrictions.
SAP / SDP Data
Note – SAP is Session Announcement Protocol and SDP is Session Description Protocol
as defined in RFC2327 and RFC2974

Service Name – textual information naming the multicast stream as
delivered in the SAP/SDP packets from the unit. Default is “MPEG
Stream”

Info – further textual information about the multicast stream as delivered
in the SAP/SDP packets from the unit. Default is “NetEng”

Description - Optional URI (Universal Resource Identifier) pointing to a
web page on the network containing additional information about the
multicast. Default is www.domo.co.uk

Bitrate - textual information indicating the bitrate in kbits/s of the stream.
Default is usr kbit/s

10 Software Decoder
10.1 General Information
The domo software decider application (part number NETSWDR) is
delivered on CD. The product is installed by following the prompts
offered by a comprehensive Install Shield.
The product is licensed, after installing the product from the Installation
shield the user should double click on the application icon, which may
appear as depicted below.
Note – later revisions of the software decoder may feature different icons or application
names.
When the application is executed, if the PC is unlicensed then the
following prompt box appears
Assuming the user has pre-paid for their Software decoder licence then
the user then simply needs to email the Electronic Serial number to
domo (sales@domo.co.uk) quoting the pre-paid token number. After
receipt of this email domo will then provide a licence key. The licence
key should be entered into the prompt box in the application window
above which will licence the PC.
The license is tied to the target PC, and reinstallation of the product on a
different machine will require the purchase of further licenses from
domo.
Note – if a user has not purchased a pre-paid licence then the user will have to contact
domo sales to purchase a licence prior to receiving a licence code.
62
The domo software decoder can decode and present MPEG streams
that are available from two sources.

Multicast streams being played out on the connected network by a
NETSTREAM or NETCRXIPUP IP upgrade in the CRX.

Files available locally on the target PC or network.
10.2 Decoding Multicast Streams
If the application is started on a PC, which is connected to a network
shared by the NETSTREAM or CRX IP stream, then it will present a
view of available streams that can be software decoded and viewed on
the PC.
The name of the multicast stream is listed in the window, alongside an
expandable crosshair. Clicking the crosshair presents the streams
multicast details and a list of any services contained within a stream:
63
In the above example the stream “DVT Streaming” has a multicast
address of 239.16.33.253 and is streaming to port number 10000. It
contains two services, named “CRX-001” and “CRX-002”.
It can be seen that there is an expandable crosshair alongside each of
the service names. Clicking these provides more details about each
service:
In this case we see that the service “CRX-001” is unencrypted, uses
MPEG2 video encoding, and has single channel (mono) audio encoded
with an 8-bit companding scheme with a sampling rate of 16kHz.
64
To start decoding a service the user should “double click” the
appropriate service name. Service names are always highlighted in bold
text in the main player window. If the service is unencrypted the main
decoder window will be launched.
10.3 Encrypted Streams
If the service selected is being encrypted by upstream hardware, then
the user will be prompted for the reciprocal key. The video stream player
can detect from information in the stream whether ABS or AES
encryption is being used. It will present a window appropriate to the type
of encryption. For ABS the following window will appear:
This requires the 32-bit ABS decryption key to be entered as 8
hexadecimal characters. This is not case sensitive.
Although the player is able to distinguish a service encrypted with AES,
it cannot detect whether 128-bit or 256-bit AES encryption has been
used. Therefore the following window will be presented to the user when
AES encryption is detected:
By default this window is expecting a 128-bit (to be entered as 32
hexadecimal characters) decryption key. If the service is encrypted with
AES256 encryption, the user should select this from the “Scrambling
65
type” drop-down list in the window. The appearance of the window will
then change to the following:
The user can now enter the AES256 key in the two fields provided.
Once the key is entered, the main decoder window will be launched.
66
10.4 Main Decoder Window
The main decoder window will appear as follows:
The title bar of the window presents the service name and the streams
multicast details. Below this there is a menu-bar with an Options dropdown menu and a toolbar with some icons on it. Each of the icons
corresponds to a selection in the Options menu. The following
selections are available in the menu:
Record to file
This option gives the user the option of recording the file that is being
decoded to disk.
The user is prompted with a standard Windows “File Save” dialog box:
67
When recording is active, this menu option is changed to “Stop
Recording” which can be used to stop writing to disk.
Two buttons on the toolbar can be used to control recording:
to start recording
to stop recording
When recording is inactive, the stop recording button will appear greyed
out and unselectable. The start recording button will appear in similar
fashion when recording is active.
Enable audio
This option will only appear in the menu if the service has audio. When
more than one service includes audio only one window can decode
audio at any one time. When audio is enabled in a service, the enable
audio option will appear with a tick beside it in the menu:
Selecting this option simply toggles whether audio is enabled or
disabled. If another window was previously decoding audio it will be
forced to disable its audio as the new window is now the audio decoding
window.

10.5 Decoding Locally Stored Files
If the user wishes to play a file from local storage (regardless of whether
multicast streams are available or not) then the “Play from File” button
on the main application window should be pressed.
This opens a standard Windows “Open File” dialog box to make the
selection.
Note - the default file extension is *.mpg.
The application will scan through the selected file for any services
available. If the stream contains only one service the application will
select this automatically and operation will be as described in the
preceding sections after a service is selected.
If there are multiple services in the file the application will present a popup window with a list of the services in:
The user should “double-click” the service they wish to decode.
Thereafter, operation is as described in the preceding sections.
10.6 Miscellaneous application options
The main application window has a menu-bar with an Options dropdown menu. This presents the following selections:
69
These options relate to the main application icon, which normally
appears as
and an optional logo. By default there is no logo
presented. The user may select a bitmap to appear as a logo below the
“Play from file” button on the main application window.
Selecting either the “Set icon source” or “Set logo source” options will
open a standard Windows file dialog box. For icon files, this is set to filter
for files with a .ico file extension. These are standard Windows icon files.
A 32 x 32 pixel icon is expected. For logo files, the dialog box is set to
filter for bitmap files with a .bmp file extension. The size of the bitmap file
is not important as the application will automatically make it fit to the
available space. The logo size can be altered by selecting the “Set logo

No RF Link
Check a suitable transmitter RF source is active, on correct frequency.
Ensure Downconverters are connected. Ensure antennas are
connected to downconverters. Ensure there is no interfering signal.
Poor link
performance
Poor performance of the link can occur for the following reasons.

Interference. Should an interfering RF signal occur on the
same frequency the performance of the link will be affected.
Remove the interferer e or move to an alternative
frequency.

Unsuitable antennas, or out of band antennas. See the
antenna sections for guidance on antenna selection and
use.

Reduced transmit power, ensure that the attenuation
setting on the transmitter is appropriate for direct output, or
for amplifiers connected.

Receive antenna positioning, were possible mount the
receive antennas away from other objects, unobstructed
and as high as possible. Poor alignment of directional
antennas.

No Diversity operation. Ensure both down converters are
operational.

Check scrambling keys are matched.
Reduced
Image quality is affected by the selected horizontal resolution. The
Image
image will become progressively softer for each horizontal resolution
quality
below the sharpest resolution of 704 pixels. It is advisable to select a
horizontal resolution that matches the resolution of the camera.
Image quality is also affected by the video bit rate which can be read
from the video bit rate field of the SOLO transmitter controller). The
standard setting is 2.3Mb/s. However enabling audio, particularly the
high quality audio modes, will reduce the video bit rate substantially.
Therefore ensure an appropriate audio mode is selected or audio is
fully disabled if not required.
No audio
Ensure audio is enabled at the transmitter (disabled by default).

Note: For GPS data to appear on the OSD several conditions need to be met. A
compatible GPS receiver with NMEA output should be connected to the data port of a
transmitter. The transmitter must have Data enabled and the correct Baud rate set (usually
4800 for NMEA), and the receiver must have Data enabled.

13.5 Frequency Scan Page
The Frequency Scan page automatically sweeps through a set tuning
range and plots the signal power at each frequency. It can also
automatically provide a list of decodable services within that range.
Starting a Scan
The front panel MODE button is used to start a scan whilst on the
Frequency Scan page. The MODE button can then be used to stop a
scan at any time. A scan consists of two stages which are described
below.
During the scan any previous video link will stop working but will be
restored once the scan is completed or stopped.

0.00GHz
Minimum and maximum
signal level; this will
change during a scan as
the plot is automatically
scaled.
Frequency scale in GHz
shows the scan range
once a scan has started.
Setting the Scan Range
The Scan Range and Resolution settings can be changed remotely
using RS232 control commands (see section 0), or by using the
Receiver Control Application (see section 8.3).
All settings default at 0 which means a range will be picked 100MHz
either side of the current frequency at 0.25MHz resolution.
It’s recommend that you set the scan range (maximum and minimum
values) to the range in which your transmitters usually operate.
Maximum and minimum values will be automatically limited based on
the receiver’s ability with its current settings. Total scan range is limited
to 500MHz.
Resolution should be set based on your usual frequency settings. If your
transmitters are always set to multiples a 1MHz then the resolution
should be set to 1MHz. A smaller resolution will result in a scan taking
longer to complete. Resolution defaults to 0.25MHz if set out of the
range 0.25MHz to 100MHz.
77
Quick Scanning Stage
The quick scanning stage skips though the frequency range at intervals
depending on the resolution, and measures the signal level at each
interval. The signal level is taken as the maximum level at all available
antenna inputs and is plotted on the on screen display.
A chequered bar will move along the frequency axis representing the
current progress.
This stage is necessary for the service scanning stage, however if the
users’ aim is to check for noise free frequencies to put their service on,
then the scan could be stopped at whatever point by pressing the
MODE button.
Service Scanning Stage
The service scanning stage jumps between the strongest signal levels
detected and checks for a decodable service.
If a service is found, signals around it will be ignored to save scanning
time as they are mostly likely part of the service. The number of
surrounding signals ignored depends on the bandwidth of the service
found.
Once a scan is finished, services found will be marked by a chequered
bar and stored. If a scan is stopped early the services found so far will
be marked and stored.

OSD Timeout
A timeout has been implemented such that if a timeout value is set and
there is no defined activity, then the OSD will automatically turn off after
the set period of time.
The timeout value can be set by using the On Screen Display Timeout
(ost) command (see section 0).
If the timeout is set to 0 (which it is by default) then the OSD timeout is
disabled.
Defined Activity
Certain activity will reset the OSD timeout counter:

Pressing the MODE / RF / CONFIG front panel buttons.

If the OSD page is changed by any method.

When a frequency scan finishes.

If the device is reset.
The timeout is not active whilst a frequency scan is running.

15 Control Protocols
The following section describes the control protocol employed on the
RS232 link for controlling the SOLO transmitters and receiver
equipment.
Connection details are detailed in previous sections.
Note that only features that are licensed for use in the SOLO units can be controlled. The
protocols listed here cover all possible features. Attempting to activate an unlicensed
feature will simply result in the command being ignored by the SOLO unit.
15.1 RS232 Control – General Principles
The physical interface is RS232 but this can be converted to RS 485
with an external adapter where multiple units are controlled over one RS
485 bus.
Normal operation involves sending a packet from the control device
(normally a PC) to the device being controlled. If the packet satisfies an
address integrity check, then the controlled device will action the
command and send a reply.
For compatibility with modems an ASCII style protocol is used.
Ports are set for 8 bits, No parity, 1 stop

General error, Command could not be actioned
Typically E will be returned if the message is formatted incorrectly
(separators in wrong place) or if commands are in upper case, or if
commands do not match against the allowed list of commands, or if the
checksum is wrong.
Addresses in the range 0001 to 9998 are for general use. Address 0000
is reserved and 9999 is a broadcast address. i.e. any device will reply to
this address. Its reply will contain its own specific address.
All data in the transmitter and receiver is stored as one of 5 data types,
Double, String, List, Integer or HexInteger. The data type dictates the
contents of the data section of the reply.

List – 1 byte for sending. Value is hexadecimal coded as ASCII. 2 byte
reply. Reply represents index into original choice list. e.g. Reply 02
indicates entry 2 in original list.

Double - variable length. Reply always contains decimal point and 4
decimal places. Can have 1 to 3 digits before decimal.

Integer - 6byte reply. integer value with stuffed with preceding zeros.
e.g. GOP reply 000012 = GOP length 12

String - Variable length. Reply is string excluding null terminator

HexInteger – 8byte Hex reply
