4 Introduction

The domo SOLO4 (and SOLO2) product range enables the user to

build wireless digital microwave video systems. The domo SOLO4

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 system is a digital system that uses the COFDM

modulation technique, which effectively eliminates the problems caused

by multi-path and reflections.

The domo SOLO4 Central Receiver system, is a highly flexible solution

for use in permanently installed central receive applications. The

Central Receive system can be supplied with the following flexibility.

• Four built in receivers.

• Four way diversity.

• Built in rebroadcast transmitter for down link (option)

• Built in ethernet for network control and streaming of received

video.

• 19’’ Rack mount configuration, for indoor rack or easy

integration into outdoor box.

The domo central receiver is typically installed at a permanent elevated

receive point and is receiving and decoding the transmissions from up to

four transmitters simultaneously. The transmissions are received

through one of four antennas typically mounted on the four corners of

the building for omni coverage. The multiple video and audio outputs

are typically viewed locally or are down linked using the built in

rebroadcast transmitter to the domo Down Link Receiver.

The domo narrow bandwidth modulation offers unpredicented spectrum

efficiency, while also increasing the system sensitivity and therefore

range.

The central receiver and down link receiver have comprehensive On

Screen Display diagnostic capability to show link quality and spectrum

analysis. Security of transmission is ensured by the use of optional

AES128 / 256 bit encryption algorithms (optional).

Features:

• Four simutaneous video reception and viewing.

• Comprehensive Demodulation 8 / 7 / 6 / 2.5 and 1.25MHz

• Up to four way Maximum Ratio Combining antenna diversity for

fade and multipath elimination.

7

• Built in options for rebroadcast or IP network distribution

(optional)

• Rack mount hardware solutions. Weatherproof outdoor

solutions available on request.

• Comprehensive On Screen Display (OSD) diagnostics for link

analysis, including spectrum analyser.

• Internal AES 128 / 256 (optional)

• Monitor Video output, selectable between any of the four

channels and a quad split mode.

Applications:

• Police metropolitan and urban observation

• Key building surveillance

• Military command and control posts

• Airport Ports and Terminal security

• Border control

• Major Incident Support

Users:

• Police Technical Support Units

• Police Silver and Gold Command

• Special Forces

• Cutsoms and Excise

• Security Services

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 and

2.400 to 2.483GHz.

1.7 Connecting the Central Receiver in a Typical Roof Top

Installation

The following section describes how a Central Receiver should be

connected when used in a typical permanent roof top installation.

Location of the Central Receiver

The domo Central Receiver has been designed so that the

downconverter units are mounted remotely from the receiver unit, and

connected via the 3-5 metre TNC cable.

Note: If a longer cable run is required between the Central Receiver and the Down

Converter, the DCX High Gain down converter should be specified. The DCX will typically

drive 25-50m of cable.

The domo SOLO4 Central Receiver is a standard 19’’ rack unit

equipment and is designed to be mounted in an equipment rack or

shelter and must not be exposed to the elements. The receiver is

neither splash resistant, nor waterproof, so it should not be exposed to

moisture. The domo SOLO4 Central receiver is not self cooling and is

fitted with equipment fans. It is essential that sufficient free air space is

available on both sides of the Central Receiver to allow and unrestricted

flow of air through the equipment. Failure to do so may damage the

Central Receiver.

In a typical installation the Central Receiver will be installed on the roof

of a tall building, in this situation, the Central Receiver will either be in a

weatherproof box (domo can supply on request) mounted to the parapet

wall of the building, or will be installed in an equipment rack typically in

the lift house of the building.

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 SOLO4 Central Receiver is a quad diversity receiver and will

give optimum results only when all four 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 labelled

‘ANT A / B / C / D’. Care should be taken not to over tighten the TNC

connectors. Where longer cable runs are required the DCX high gain

down converter should be employed.

The downconverters 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 domo SOLO

Central Receiver 3 metre long cables are provided, allowing the

downconverters to be positioned remotely from the receiver.

14

It is important that the downconverter 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.

The downconverter 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.

Typically antennas and down converters will be positioned outside,

usually on the roof of a building or a vehicle. In a typical installation one

antenna will be mounted to face out from each corner of the building,

giving a 360 degree coverage area. For long range requirements high

gain sector antennas can be employed and the domo ANT12S or

ANT12L are ideal for this purpose. When these 12dBi sector antennas

are deployed on each corner of a building 360 degree performance can

be achieved with 12dBi gain.

The domo Central 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 on 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 Central 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

ANT2L or ANT2S 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 labelled ‘ANT/RF IN’.

1.8 Powering on the System

In this section a SOLO4 Central Receiver will be used to receive and

decode four SOLO4/2 transmitters.

Note: This section assumes the user is confident in the operation of SOLO4/2

transmitters. If in doubt the user should read the SOLO4/2 Transmitter Hand Book.

Four SOLO4 / 2 transmitters should be set up as described in the

SOLO4/2 handbook, each with the following connections.

• Video Source.

• Power Source.

• RS232 Control connection to a PC operating the SOLO4/2

controller GUI.

All external connection to the SOLO4 Central Receiver should be made,

as described in the previous sections, before proceeding to power on

the system. All external connection to the SOLO Transmitter products

should be made, as described in the relevant sections of the SOLO4/2

Handbook, before proceeding to power on the system.

Setting Frequency on the Transmitters and Central Receiver

It is assumed that the frequency selected for the transmitters is matched

with the frequency specified on the SOLO4 Central Receiver.

Transmitter 1 Frequency = Receiver 1 Frequency

Transmitter 2 Frequency = Receiver 2 Frequency

Transmitter 3 Frequency = Receiver 3 Frequency

Transmitter 4 Frequency = Receiver 4 Frequency

If the frequencies do not match or the user is unsure, then consult the

advanced section of this manual on how to set frequency on the SOLO4

Central Receiver, and the advanced section of the SOLO4/2 transmitter

manual on how to set frequency.

Applying power to the Solo Central Receiver

On powering the SOLO4 Central Receiver, the Power LED will light as a

‘Solid’ green colour and progress to a flashing green. The sound of the

internal cooling fans will be heard. The four status LEDs will be red.

Applying power to Transmitter 1.

When powering transmitter 1 directly from a 12V source, or from a

connected battery, the following will be observed.

19

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

transmitter was switched off).

The alarm LED may be lit if there is no active video source.

Switch On RF on the transmitter

On the transmitter unit (either VehicleCam or BodyCam) 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.

Note: Ensure that the transmitter is not too close to the SOLO4 Central receiver, or

damage may occur. Typically allow at least 10m separation.

Observe Video on the Central Receiver Outputs

Video and audio signals will be presented automatically at the Central

Receiver outputs labeled Receiver 1 – ‘Composite’ and ‘Audio’, on the

front connector panel. This occurs as the Central Receiver locks to the

RF signal from the transmitter. The Status 1 LED will go to green.

Video will also appear on the top left quadrant of the quad spit monitor

output.

Powering on transmitters 2 to transmitter 4

Power on transmitters 2, 3 and 4. Video and audio signals will be

presented automatically at the Central Receiver outputs labeled

Receiver 2, 3, 4 – ‘Composite’ and ‘Audio’ respectively, on the front

connector panel. This occurs as the Central Receiver locks to the RF

signal from the transmitter. The Status 2,3 and 4 LEDs will go to green.

Video will also appear in the remaining quadrants of the quad spit

monitor output.

SOLO4 Central Receiver Remultiplexing

The SOLO4 Central Receiver has a built in automatic re-multiplexing

function. There is no requirement for users to automatically set service

names or PIDs on the transmitters prior to use.

The SOLO4 Central receiver will automatically remap services names

that it receives on its inputs.

Tranmitter 1 – Received on Receiver 1 – Output Service Name = CRX-001

Tranmitter 2 – Received on Receiver 2 – Output Service Name = CRX-011

Tranmitter 3 – Received on Receiver 3 – Output Service Name = CRX-021

Tranmitter 4 – Received on Receiver 4 – Output Service Name = CRX-031

20

Services that are rebroadcast using the optional IP streaming function,

or the optional microwave re-broadcast function will be identified by the

new service name CRX-xx.

Diagnostic On Screen Display (OSD)

The SOLO4 Central 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. The OSD function is available individually for

each of the receivers within the SOLO4 Central Receiver. The OSD

function can be selected from the CRX control application, this is

described in more detail in the advanced section.

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
