Introduction
The SOLO4 Bodywire Transmitter is a COFDM digital video transmitter,
designed specifically for covert video installations and body worn
applications.
The small size and low power consumption of the SOLO4 Bodywire
make it the product of choice for covert video hides, or applications
requiring long term battery power deployments, small unmanned aerial
vehicles, and body worn or body wire use.
The SOLO4 Bodywire transmitter employs MPEG2 (MPEG4 is also
available) encoding for excellent image quality retention. Equipped with
integral COFDM modulation, the SOLO4 transmitter is ideal for
establishing rugged wireless video links in all environments including
mobile and urban environments. Offering several user selectable
modes that trade off image quality against range, the SOLO4 transmitter
is ideal for all mission types. The SOLO4 Bodywire includes RF upconversion and PA circuitry to make a complete single board
transmitter. SOLO4 Bodywire is supplied in a simple light weight case
with an attached break out cable.
Security is ensured with optional in AES128/256 Encryption.
The SOLO4 Bodywire transmitter will transmit images in a non line of
sight environment up to 750m depending on mode and frequency;
further range can be achieved with the booster PA.
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, or in
bands specified by the appropriate authorities.

Option 4. Cutting off the connector and wiring direct to the cable
For very small integrations, or integrations where weight is a premium, it
is possible to cut away the 15 way DType connector and wire direct to
the cables. Domo would prefer this did not happen, but understands
that it may be necessary. If this is the preferred integration route, then
users should contact domo for technical advise, and for confirmation of
warranty implications.
This operation will require users to cut the wires to the transmitter,
peeling back the wire sheath to reveal the inner core. Many of the wires
are multi-cored. The core of of the wires is coloured to help with
13
identification. However 2 of the 5 wires are identical in which case it is
position information that is used to identify them.
Looking at the five wires as they enter the rubber grommet on the base
of the unit you will see.

Integration in Covert Hides
Users should be aware of the following issues when integrating the
equipment in any covert hide.
1) Ventilation: The equipment does not require forced air cooling, but
ideally should be mounted to a metal surface for cooling effect.
Ideally the low power 50mW mode should be employed to reduce
the consumed power.
2) Long cable runs from the RF output to the antenna should be
avoided, for maximum range.
3) The antenna should be mounted vertically ideally, and exposed to
free space.
4) The equipment should be supplied with a clean supply in the range
5.9 to 16V and capable of 0.4A maximum.
5) The equipment should not be exposed for any long periods to any
form of liquids.
Integration in Vehicles
Users should be aware of the following issues when integrating the
equipment into vehicles.
1) Ventilation: The equipment does not require forced air cooling, but
ideally should be mounted to a metal surface for cooling effect.
Ideally the low power 50mW mode should be employed to reduce
the consumed power.
2) For the additional range required in vehicle applications, the use of
amplifiers should 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.
3) Long cable runs from the RF output to the antenna should be
avoided, for maximum range.
18
4) The antenna should be mounted vertically ideally, and exposed to
free space.
5) The equipment should be supplied with a clean supply in the range
5.9 to 16V and capable of 0.4A maximum. Care should be taken to
avoid direct supply from the vehicle 12V which can be very noisy.
Power conversion will be required for 24V vehicles.
6) The video input can be connected across long video cable lengths
so remotely mounted cameras should pose no problem.
7) The SOLO4 Bodywire transmitter has an IP66 rating, however
equipment should not be exposed for any long periods to any form
of liquids.
Overt 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.
19
The SOLO4 Bodywire transmitter has been successfully tested with a
wide variety of standard and pinhole cameras. domo can supply
cameras 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 SOLO4 Bodywire transmitter has an IP66 rating, however
equipment should not be exposed for any long periods to any form of
liquids.
Covert Body Worn Applications
For covert body worn applications domo recommends the use of its
body worn harness cable (available early 2009). This cable integrates
to a variety of cameras, and microphones. The cable enables camera
power, provides ON/OFF capability and battery interfacing.
In covert applications, ultra slim patch antennas can be used, for best
coverage ideally split front back patch assemblies. domo can supply
both single and dual split patches in ultra slim configurations, please
contact domo for details.
20
Powering on the System
All external connection to the SOLO4 Bodywire transmitter should be
made, as described in the previous sections, before proceeding to
power on the system.
Users should ensure that a suitable receiver is available and configured
to the appropriate frequency before proceeding with the remainder of
this chapter (see handbook for the SOLO4 receiver or SOLO4
MicroVue)
Apply power to the transmitter
Power the transmitter directly from a 12V source, or from a connected
battery, allow 5 seconds for the transmitter to boot. Once the transmitter
has booted lock will occur at the receiver.
There are no external indicators on the transmitter.
If lock does not occur at the receiver, the following possibilities should
be considered.
RF Lock was not achieved at the Receiver
If power has been applied to the transmitter, but no RF lock has been
achieved at the receiver, then there are several possibilities, however
most of these possibilities require the connection of either the PC GUI
controller (see section on Advanced Operation), or the Field Gun (see
Field Gun section) to diagnose.
•
The frequency of the receiver and transmitter are different. Use
PC Controller or Field Gun to change frequency.
•
The RF Output of the transmitter is OFF. Use PC Controller or
Field Gun to set the RF output ON.
•
The Modulation styles are set differently between the
transmitter and receiver. Use PC Controller or Field Gun to set
modulation styles to be the same.
•
Check connections to the antennas and down converters at
each end.
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.
21
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.
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
approximately a 5dB margin. Failure of the link will occur when the
power level reaches –97dBm or the SNR reaches 2dBm
1.3
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 SOLO4
Bodywire
22
Using the SOLBAT
The domo SOLBAT is used for powering domo transmitters.
The domo SOLOBAT can not be connected directly to the Bodywire
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 CA0317 transmitter break out cable 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
23
Approximately 2 hours should be allowed for a full charge of the
SOLBAT battery.
1.4
Using the Clip On 1W Amplifier
Additional range can be achieved by connecting the SOLAMP1W clip
on amplifier to the domo Bodywire 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
•
PA to Bodywire adaptor cable
Amplifier Connection
The domo SOLAMP1W is designed to mount directly onto the
SOL4/SOL2 transmitter. It will not mount directly to the SOLO4
Bodywire, to achieve connection following steps should be taken.
1.
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.
2.
Connect the PA to Bodywire adaptor cable inline, between the
15way DType female on the bodywire and the 15way DType
male on the CA317 Break Out cable.
24
3.
The 3 pin Lemo spur protruding from the PA to Bodywire
adaptor cable, should be connected to the PA to provide power
and PA enable.
DC Power and Control Cable
The SOLAMP is powered by the SOLO4 Bodywire 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.
25
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.

Using the booster 5W Amp
Additional range can be achieved by connecting the AMP5W-xxxxxx
booster amplifier to the domo SOLO4 Bodywire transmitter.
Connections
This section describes how to connect the following model numbers.
•
SOLAMP5W-115140
•
SOLAMP5W-225255
The domo SOLAMP-xxxxxx is supplied with the following cables:
•
RF Cable
26
•
DC Power Cable
RF Connection
The domo AMP5W has the following input power requirements.
AMP5W-115140: Input Power 100mW or 20dBm
AMP5W-225255: Input Power 100mW or 20dBm
Therefore care must be taken when connecting the AMP5W-225255
product to the SOLO4 Bodywire transmitter.
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.
Note the 5W power is illegal in many frequency bands and should not be used by unlicensed users.
If customers are concerned on this issue, they should contact domo for advise.
If customers are concerned about balancing the input power when connecting 5W
amplifiers, then they should contact domo directly.
DC Power
Push the connector on the DC power cable into the socket labelled DC,
taking care to align the connectors. Connect the banana connectors on
the other end of the cable to a suitable DC source.
The 12V DC input has the following characteristics.
•
Input Voltage Range – 12V +/- 1V, reverse voltage protected.
•
Current Draw 4A SOLAMP5W-225255, 2.5A SOLAMP5W-115140
Antennas
domo 5W Amp 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
N 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
5W Amp. Use of cables will degrade performance.
27
Installation Notes
The domo 5W AMP 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 5W AMP 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 5W AMP 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 5W AMP is splash resistant, but is NOT waterproof, so it should not
be exposed to moisture for prolonged periods. The 5W AMP is not selfcooling so should be connected to a metal surface; if this is not possible
the heat sink should be fitted and the unit should be deployed in a
ventilated environment.

Advanced Operation
1.1
SOLO System PC Controller Application Software
Advanced control of the SOLO4 Bodywire 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 SOLO4 Bodywire transmitter products are controlled by the
solo_tx_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
29
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.

Connectivity
Status
Bandwidth Mode
The Bandwidth Mode switches the unit between either domo
Narrowband (2.5MHz or 1.25MHz channel bandwidths) or DVB-T 8MHz
bandwidth. To select 6MHz and 7MHx DVB-T modes the user must first
click on ‘Advanced’ to enter the Advanced setting page.
Audio
Turns ‘On’ or ‘Off’ a basic audio setting – the audio settings are
optimised considering the bit-rate of the selected Transmit mode. The
user can set there own audio settings using the ‘Advanced’ page, if
required.
Default Transmit Mode
In Narrowband the user has the following pre-defined modes available
from the main window. Note that the Ultra Long Range Mode is only
available to users who have purchased the SOLO4TXUP option
(1.25MHz and MPEG-4 modes). The user can of course define their
own specific FEC, bandwidth and modulation requirements from the
‘Advanced’ page.
Ultra Long Range:
1.25MHz QPSK FEC 1/3 (optional)
Long Range:
2.5MHz QPSK FEC 1/3
Medium Range:
2.5MHz QPSK FEC 2/3
Short Range:
2.5MHz 16QAM FEC 2/3
In DVB-T the available modes are
QPSK ½ FEC 8MHz 1/32 Guard Interval
QPSK ¾ FEC 8MHz 1/32 Guard Interval
16QAM ½ FEC 8MHz 1/32 Guard Interval
Scrambling
If the AES scrambling option has been purchased for the SOLO4
Bodywire 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. The actual scrambling key
can then be entered by clicking on the yellow ‘key’ icon.
File Options
Load Config – used for loading a single configuration data from text file.

Output Frequency (MHz)
The transmit frequency can be changed by entering the new desired
frequency in this field. Values outside the range supported by a
particular transmitter type will be rounded to the highest of lowest
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.
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.
34
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.
The licensed SDI digital video input can also be selected.
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).
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
MPEG4 reduced frame rates be employed when the unit is operating at
low bitrates (1.25MHz bandwidth FEC1/3).
35
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.
When the Manual radio button is enabled, the user can manually set a
video bitrate upto the maximum value. When manual bitrate is selected,
the user is in control of the video bitrate, this can be usefull when
configuring chaining systems.
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.
Video Profile
This allows the user to select between the default 4:2:0 profile and the
ultra high quality 4:2:2 profile (only of interest to Broadcast customers).
Note 4:2:2 is a licensed feature.
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 bitrates 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
36
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
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).
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.
37
Software Version (Status Only)
This status information describes the version of the software running the
SOLO transmitter product.
FPGA Version (Status Only)
This information is for domo engineering use only.
Serial Number (Status Only)
This status information is the electronic serial number of the transmitter
PCB. This number can be exchanged with domo to purchase extra
licensable features, such as upgrades to support AES encryption.

Fault Finding
Symptom
Suggested Action
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.
Blue screen

Receiver RF LED lit. Check video is enabled at the transmitter. Check
correct unit name is selected at the receiver to match the transmitter.
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).

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.
1.4
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

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
