5 3 About this Manual This manual describes the operation of domo SOLO2 and SOLO4 digital wireless systems. The manual is divided into three main sections.  Getting started and basic operation This section describes to users how to deploy and use a domo SOLO system.  Advanced operation This section describes the operation of the system in more detail, concentrating particularly on how to store and recall configurations, with use of the PC Controller Application.  Technical reference This section provides technical specification and control protocol data and will be of interest to those integrating the SOLO system into larger systems.
6 4 Introduction The domo SOLO4 and SOLO2 product range enables the user to build wireless digital microwave video systems. The domo SOLO4 and SOLO2 products have been designed to provide rugged point-to-point links for high quality full frame rate video, and audio, even in non line of sight and urban environments. Existing analogue systems suffer from impairments such as video noise, loss of colour information and poor image quality when line of sight cannot be maintained, and solutions based on wireless internet standards and PC platforms deliver poor quality video. The domo SOLO4 and SOLO2 system is a digital system that uses the COFDM modulation technique, which effectively eliminates the problems caused by multipath and reflections. The SOLO product range allows law enforcement, surveillance and emergency service communities to now receive the highest quality video images, in real time, direct from personnel, buildings and vehicles. The domo SOLO2 system employs the DVB-T 2K carrier COFDM technology. The domo SOLO4 system employs a revolutionary narrow band 2.5MHz COFDM technology which demonstrates better propagation for longer range links, and extra bandwidth efficiency. The domo SOLO4 system can also be upgraded to include a 1.25MHz COFDM modulation and MPEG4 compression for excellent range performance. The domo SOLO4 and SOLO2 systems employ common transmitter and receiver hardware.  The SOLO4 and SOLO2 transmitter is a lightweight, low-power transmitter suitable for body-worn applications where size, weight and power consumption are at a premium.  For longer range applications such as vehicle transmissions, the SOLO4 or SOLO2 transmitter can be upgraded with the use of a booster amplifier.  The SOLO4 and SOLO2 receivers are diversity input receivers with extensive built in spectrum analysis tools. The receivers can be fitted with an optional NETSTREAM card, which then gives the option of streaming the received video onwards over IP networks. IMPORTANT NOTE The SOLO4 and SOLO2 product range has been specifically designed for government security and law enforcement users, the equipment will tune across frequencies that are only available to licensed government users. Non-government users should employ the equipment restricted to the license exempt bands only typically 1.389 to 1.399GHz, 2.400 to 2.483GHz and 5.725 to 5.875GHz

18 Antennas domo transmitters are supplied as standard without antennas. An antenna must be connected for normal operation. The transmitter unit is supplied with a panel mounted SMA connector which carries the RF output. The antenna should be connected by screwing it onto the SMA, but care should be taken to not over tighten the connector. The transmitter has the following RF output characteristics.

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.
19 Application Antenna model number Mobile body worn application 1.00 to 1.40GHz - ANTBCL 2.28 to 2.50GHz - ANTBCS Mobile vehicle application 1.00 to 1.40GHz – ANT4L 2.28 to 2.50GHz - ANT4S 4.80 to 5.15GHz – ANT6C Long range point to point link 1.00 to 1.40GHz – ANT12L 2.28 to 2.50GHz – ANT12S Note. When using antenna types ANT4L, ANT4S, ANT6C, ANT12L and ANT12S with domo transmitters SMA to TNC adaptor connectors will be needed. Other antennas for more specialist applications, such as aircraft use or covert surveillance use are available on request from domo. Control Cable The control cable is used for connecting the transmitter unit to a PC when using the domo PC control application. The PC control application is described in more detail the Advanced Operation section of this handbook. Installation Notes The domo transmitter has been designed specifically for body worn applications; however it is a general-purpose wireless video transmitter and can be used in many applications including the following.  Body worn portable applications  Vehicle based applications This section gives guidelines for how to install the transmitter in the above applications.
20 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.
21 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 self-cooling; however it should be mounted in a ventilated environment. Forced air cooling is not required.
22 7.3 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 down-converters; 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
23 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 down-converter. 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.
24 Square down-converter New Style Barrel down-converter NOTE : The LO Frequency setting in the SOLO4 Receiver controller has changed compared to the older square L-Band (1.1 to 1.4GHz) and S-Band (2.28 to 2.55GHz) products. The LO frequency MUST be set absolutely correctly for the system to work properly. This can be set using the Solo4 Receiver controller software – see section 3.3 of this manual for details on use of the controller. RF Parameters L-Band DC-100140 S-Band DC-225265 Frequency In 1000MHz to 1500MHz 2250MHz to 2650MHz Local Oscillator 1700MHz 1880MHz High Side or Low Side High Low Gain (DC variant) 9dB 9dB Gain (DCX variant) 19dB 19dB RF Parameters L-Band DCB-100150 L-Band DCB-150200 S-Band DCB-200250 S-Band DCB-250300 3GHz DCB-300350 C-Band DCB-450500 C-Band DCB-550600 Frequency In 1000MHz to 1500MHz 1500MHz to 2000MHz 2000MHz to 2500MHz 2500MHz to 3000MHz 3000MHz to 3500MHz 4500MHz to 5000MHz 5500MHz to 6000MHz Local Oscillator 1800MHz 2300MHz 1700MHz 2200MHz 2700MHz 4200MHz 5200MHz High Side or Low Side High High Low Low Low Low Low Gain (DCB variant) 9dB 9dB 9dB 9dB 9dB 9dB 9dB Gain (DCBX variant) 19dB 19dB 19dB 19dB 19dB 19dB 19dB
25 There are two styles of domo SOLO receiver box shown below. domo SOLO receiver with Box style 1. domo SOLO receiver with Box style 2.

28 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 down-converter 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 down-converters 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 Connect the video output lead to the BNC connector labeled ‘VIDEO’ on the SOLO receiver and to the chosen video display device.
29 Connector Signal Video BNC 75 ohm composite video output, PAL or NTSC software selectable at the transmitter Typically the video display device will be a high quality monitor. Audio Connection Push the LEMO connector into the socket labeled ‘AUDIO’, taking care to align the connectors and connect the chosen audio output device. Connector Signal Audio Plugs Line level, +7dBu clip level, low impedance source (20 ohm) Typically the audio output device will be monitoring speakers. DC Power The SOLO2/SOLO4 Receiver is powered from a nominal 12V DC supply. As standard domo supply an AC to DC converter, terminated with a 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
30 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 down-converter 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 down-converter 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.
31 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.
32 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
33 approximately a 5dB margin. Failure of the link will occur when the power level reaches –97dBm or the SNR reaches 2dBm Using the transmitter Range Mode Button The Range Mode button and LEDs on the SOLO2/SOLO4 transmitter, has the following function. SOLO2 transmitter: No Function SOLO4 transmitter: Selects the range of the transmitter. On a SOLO4 transmitter, the user can select various range characteristics, by repeatedly pressing the Range Mode Button, these can be toggled. The user should be aware that increasing the range will have the effect of reducing the image quality and increasing the video delay.  Ultra Long Range: 1.25MHz QPSK FEC1/3 (optional) (Lowest Image Quality)  Long Range: 2.5MHz QPSK FEC1/3  Medium Range: 2.5MHz QPSK FEC2/3  Short Range: 2.5MHz 16QAM FEC2/3 (Highest Image Quality) 7.5 Domo Batteries and Battery Charging Although domo equipment can be powered directly from user 12V batteries, domo also supplies a rechargeable battery pack. The following domo battery items are described in this section. SOLBAT: 7.2V 4AH rechargeable NiMH battery pack. SOLBCH: Battery Charger SOLBCC: Adaptor cable that allows SOLBAT to connect to SOL2/SOL4 TX. CONFIG RF1 2 3 4 5 6 7 8 RFALARMMODE Range Mode Button Ultra Long Range Short Range
34 Using the SOLBAT The domo SOLBAT is used for powering domo transmitters. The domo SOLOBAT can not be connected directly to the SOL2/SOL4 Transmitter, instead it must be connected using the SOLBCC adaptor cable. The SOLBCC adaptor cable provides an interface between the 4 pin DC In Lemo on the transmitter and the 6 pin DC Out Lemo on the battery. The cable is shown below. When connected a fully charger SOLBAT will power the transmitter for more than 4 hours. Charging the SOLBAT The SOLBAT can be recharged by connecting it to the SOLBCH battery charger. The SOLBAT battery can be connected directly to the SOLBCH battery charger, the interface cable is not required. When connected the SOLBAT indicator LED has the following meaning. LED Yellow: Battery not connected. LED Orange: Battery fast charging. LED Green / Yellow flash: Battery ‘Top Off’ final charging LED Green: Charging Complete / trickle charging LED Orange / Green flash: Error Approximately 2 hours should be allowed for a full charge of the SOLBAT battery.
35 7.6 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.
36 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.
37 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 self-cooling; 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
38 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 AMP5W-230250 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.
39 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. AMP5W-120140 AMP5W-230250 SOLO2 Transmitter 0dB Attenuation 10dB Attenuation SOLO4 Transmitter 0dB Attenuation 10dB Attenuation 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 ‘12V, 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 7.5A AMP5W-230250, 2.5A AMP5W-120140 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.

41 8 Advanced Operation 8.1 SOLO System PC Controller Application Software Advanced control of the SOLO2/SOLO4 system is available by using PC control applications. Typically users may want to customize the default configurations to control settings such as frequency, scrambling keys, modulation parameters, and video resolution.  The SOLO2 and SOLO4 transmitter products are controlled by the solo_tx_ctrl.exe application available on the CD delivered with the product.  The SOLO2 and SOLO4 receiver is controlled by the solo_rx_ctrl.exe application available on the CD delivered with the product. Note that exact file names may change as software version information is a part of domo file names. A PC is required with two RS232 Serial COM ports to control both a transmitter and receiver simultaneously. Where changes are to be made to either a transmitter, or a receiver, at different times, a PC with a single RS232 Serial COM part can be used. Installation of the two control programs is as simple as copying them from the CD to a suitable location on the PC. No install shield routine is launched. Note that the controllers generate their own log and initialisation files, so it is best to create a dedicated directory for these applications, perhaps with links to the applications from the desktop of the PC. Use the supplied cables to connect the chosen COM port(s) of the PC to unit(s) to be configured. Launch each application in turn by double clicking or using the run command. Connection with a SOLO product should be automatic, but the user can force selection of the correct COM port using the drop down, followed by the “Connect” button. Errors such as the following may appear during the connection process if the PC is unable to automatically ascertain which unit is connected to which COM port.  Error attempting to read invalid address  Error has occurred during polling, polling has been disabled
42 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.
43 8.2 Transmitter Control Application The ‘Advanced’ button allows the user to navigate to the controller page which exposes all available Transmitter settings. 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. Engineering Menu Polling Enable Set Polling Options Enter an Encryption Key Enter a Licence key Restore Factory DefaultsConnectivity Status Video alarm RF Output Toggle & status Current selected Config All parameter changes must be applied
44 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 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. 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. Save Config - used for saving configuration data to text file. Load Config Set – used for loading all 8 configurations from a text file Save Config Set - used for saving all 8 configurations to a text file
45 Advanced TX Controller Window 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.
46 Narrow Band FEC This option applies to SOLO4 transmitters only. The default FEC is 2/3, however improved range operation can be achieved by selecting FEC 1/3. FEC 1/3 will improve signal range by 3dB. However FEC 1/3 reduces link capacity to 1.2Mb/s therefore reducing picture quality. FEC Link Bitrate Sensitivity 2/3 2.4Mb/s -99dBm 1/3 1.2Mb/s -102dBm 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.
47 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
48 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.
49 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.
50 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. Chaining (Status Only) This field reports the status of the chaining input to the SOLO transmitter, and is not active in current units. Options Engineering – provides access to further diagnostic and calibration features. The Diagnostic and Power calibration pages must not be altered. The Advanced Options under the Engineering menu allow the user to Change RS232 address, which can be useful when connecting multiple units together via a multi drop RS485 bus for control purposes. The Serial control dialogue box allows the user to change timeouts used during the serial communications between the unit and the controller. Enable Polling – selecting this option makes the control application automatically refresh the data presented to the user every few seconds. Polling Options – selecting this option allows the user to define parameters to be regularly polled. Write Encryption Key – opens a dialogue box for entering an ABS or AES scrambling key, as 32 ASCII hexadecimal characters (0…F) Write License Code – open a further box for entering license codes for the activation of licensable features (e.g. AES scrambling) in the transmitter. Contact domo for support in applying new licenses as required. Restore Defaults – restores factory default settings in the transmitter.

53 Advanced RX Controller Window 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 Narrowband / DVB-T The SOLO2 is capable of receiving transmission in 6/7/8MHz wide DVB-T OFDM only. The SOLO4 receiver is capable of receiving transmissions in Narrowband and DVB-T. For receiving the transmissions from a SOLO2 transmitter the ‘DVB-T’ radio button should be selected. For receiving the transmissions from a SOLO4 transmitter the ‘Narrowband’ radio button should be selected. When the ‘Narrowband’ radio button is selected, then the ‘Narrowband’ column of parameters will become highlighted, and can be set. If the ‘DVB-T’ radio button is selected, then the ‘DVB-T’ column of parameters will become highlighted, and can be set. Input Frequency The receive frequency can be changed by entering the new desired frequency in this field.
54 Down converter LO This field allows definition of the local oscillator frequency in the connected downconverters. For domo supplied downconverters, this should be set as follows:  1880MHz for S band transmissions (2.28 to 2.55GHz)  1700MHz for L band transmissions (1.15 to 1.4GHz). Down converter LO side This field allows definition of the local oscillator side. For domo supplied downconverters, this should be set as follows:  LOW for S band transmissions (2.28 to 2.55GHz)  HIGH for L band transmissions (2.28 to 2.55GHz) OFDM Bandwidth This field displays the width of the received OFDM signal and should be set to 2.5MHz for normal SOLO4 system operation, and should be set to 8MHz for normal SOLO2 system operation. OFDM Guard Interval In this field the user selects the guard interval which matches the transmitter. For SOLO4 systems typically a guard interval of 1/16 is used, however on very long range transmissions a guard interval of 1/8 may be employed. For SOLO3 systems typically a guard interval of 1/32 is used, however on very long range transmissions a guard interval of 1/8 may be employed. OFDM Mode (Status Only) This field displays the COFDM constellation that is being demodulated at the receiver. In normal operation this will match that selected at the transmitter. OFDM FEC (Status Only) This field displays the COFDM FEC (Forward Error Correction) that is being demodulated at the receiver. In normal operation this will match that selected at the transmitter. Input SNR (Status Only) 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.
55 BER Pre Viterbi (Status Only) This figure is for engineering use and gives a representation of the error rate prior to the error correction techniques having been applied in the receiver. BER Post Viterbi (Status Only) This figure gives a measure of the bit error rate after error correction techniques have been applied in the receiver. Any numbers greater than 0 in this field indicate the presence of un-correctable errors in the received stream, and thus picture glitching and audio artefacts will occur. Input Level (Status Only) This figure indicates the received signal level at the two receiver inputs. Normal Operation will occur when the input level is between –15 and –90 dBm. Signals greater than –15 may be too powerful and cause damage. Signal less than –90dBm may be too weak and cause picture loss (typical link failure will occur between –95 and –99dBm). Demod Lock Status (Status Only) This indicates whether the demodulators are successfully locked to the RF signal. Data With this ON / OFF control the user can select whether the receiver extracts any data component that may be in the transmitted stream. Such data components are presented at the receiver DATA output port. Data Baud Rate (Status Only) This field reports the baud rate of any RS232 serial data component that is present and selected in the stream. Input Line Standard (Status Only) This field reports the line standard that is currently being, or last was, decoded. Power Up Line Standard Using this field the user can select what line standard of video the receiver will output (PAL / NTSC) when the receiver is first powered on and before it has locked to an incoming RF signal.
56 NTSC Mode With this control, when running in 525 line mode, the user can select whether the NTSC composite output video has a 7.5 IRE pedestal applied. Blue Screen on Fail When the link fails, the user can select between a blue field video output (YES), and a freeze frame (NO) with this option. Unit Name This field allows the user to enter an identifier for the service that they wish to receive. This must match that selected at the transmitter for the service to be decoded. The unit name can be constructed of any eight ASCII characters. Descrambling If the AES scrambling option has been purchased for the SOLO system in use, then it is possible to encrypt the link. Descrambling must also be enabled at the receiver by selecting AES128 or AES256 in the descrambling field. At this point the user will need to ensure that the correct key is in use at the receiver and this is done by selecting Options / Write AES Key in the receiver controller. The key is a 128bit value for AES128 and a 256bit value for AES256, and is entered as 32 or 64 ASCII hexadecimal characters (0...F). Decoder Lock Status (Status Only) This field reports whether the video decoder is successfully locked to the incoming digital bit stream. Current Config This field allows the user to select which of the 8 memory configs the receiver is operating in. The receiver has 8 stored configurations and the user can move between them by setting the appropriate number in this field. Changes made to other settings by the user will automatically be stored in the configuration number indicated by this field. 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 decryption.
57 Software Version (Status Only) This status information describes the version of the software running in the SOLO transmitter product. FPGA Version (Status Only) This information is for domo engineering use only. 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. Options Engineering – provides access to further diagnostic and calibration features. The Diagnostic dialogue box must not be altered. The Advanced Options dialogue box under the Engineering menu allows the user to Change RS232 address, which can be useful when connecting multiple units together via a multi drop RS485 bus for control purposes. The Serial control dialogue box allows the user to change timeouts used during the serial communications between the unit and the controller. Enable Polling – selecting this option makes the control application automatically refresh the data presented to the user every few seconds. Polling Options – selecting this option allows the user to define parameters to be regularly polled. Write Decryption Key – opens a dialogue box for entering an ABS or AES scrambling key, as 32 ASCII hexadecimal characters (0…F) Write License Code – open a further box for entering license codes for the activation of licensable features (e.g. AES scrambling) in the transmitter. Contact domo for support in applying new licenses as required. Restore Defaults – restores factory default settings in the transmitter.
58 File Set Icon Source, Set logo source, Set logo size and Set application title – allow the user to define a controller branding Exit – exits the SOLO receiver control application
59 9 NETSTREAM IP Output Option 9.1 General Info This section is relevant only to customers that have the NETSTREAM option fitted in their SOLO2 or SOLO4 receiver. The NETSTREAM can only be fitted in box style 2. The NETSTREAM product features an RJ45 socket for connection to 10 Base T or 100 Base T Ethernet networks. The network interface automatically switches between 10 Base T and 100 Base T as required. The connector is wired for straight connection to a network Hub and does not automatically compensate for Ethernet crossovers. If a direct connection to a PC is required, then an Ethernet cross over cable should be used. 9.2 Streamer The main use for the NETSTREAM card is to allow viewing of the received video/audio signal on a standard PC (or laptop) running the domo software decoder software (part number NETSWDR). Data is transmitted over the Ethernet network by means of “multicasting” i.e. continuous real-time streaming of packets accessible to any PC connected to the network. It is therefore possible for more than once connected PC to view the streamed data simultaneously. Two types of multicast IP packets are streamed.  Packets carrying video, audio and data as received by the unit;  Packets known as Session Announcement Protocol and Sessions Description Protocol data (SAP and SDP), which contain information regarding the nature and location of the stream itself. 9.3 Web Server The unit features a web server, which can be used to change the configuration of the streaming parameters. The default IP address of the unit when delivered is 192.168.0.71 A standard Internet browser can be used to reach the configuration page of the unit. The URL of the configuration page is http://192.168.0.71/index.htm Note that the address of the index page will change in the instance that the NETSTREAM IP address is subsequently changed.
60 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:
61 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
62 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.
63 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:
64 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.
65 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
66 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.
67 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 drop-down 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:
68 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. When audio is enabled, the button will appear on the toolbar. Clicking this button will disable audio. When audio is disabled this button will change its appearance and appear as , clicking which will enable audio. Close window This closes the main decoder window.
69 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 pop-up 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 drop-down menu. This presents the following selections:
70 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 size” option in the menu.

72 11.2 Fault Symptoms 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 at receiver Receiver RF LED not lit - see “No RF Link” section 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 Image quality is affected by the selected horizontal resolution. The image will become progressively softer for each horizontal resolution 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).

76 13.3 Engineering Data Page The Engineering Data page contains antenna input spectrum plots, along with GPS, temperature and video lock data received from the transmitter. 13.4 GPS Overlay The GPS Overlay is a small three lines of text over the top left of the video. The text contains a time (UTC), date, longitude, latitude and fix type as extracted from GPS data from a transmitter. If “Data Disabled” is shown the Data configuration option needs to be turned On to receive transmitter data. If Data is disabled this page will not appear whilst changing page via the front panel. 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. 14:06:59 24/07/09 50 52.136 N 3D 1 15.205 W FixEngineering Data---------------- A -65 SNR:25 | | WWWWWWWW | W W |WWW WWW ---------------- B -130 SNR: | |WWWWWWWWWWWWWWWW | | ---------------- Transmitter: GPS 14:06:59 3D 50 52.136 N Fix 1 15.205 W Case : 49’C Video: Lock Antenna input frequency spectrum plots.

If estimated case temperature or video lock status is received from a compatible transmitter this will be shown here.
77 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. 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. Frequency Scan-------------- Press MODE to perform scan -100 -90 P0.00-------------- | | 0.00- | | 0.00- | | 0.00- | | 0.00- | | 0.00- GHz 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.
78 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. Note: If the receiver is in Narrowband mode only Narrowband services will be detected as decodable. If the receiver is in DVB-T mode only DVB-T services will be detected.

79 Completed Scan Once a scan has been completed and one or more services have been found, the CONFIG button can be used the cycle though available services on screen, or to the re-scan message. If a 'change’ message is displayed then pressing the MODE button will result in changing current frequency and bandwidth settings to receive that service. Note: Changing the frequency and bandwidth settings in this way will overwrite the current configuration settings.

83 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.

86 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 15.2 Packet Structure Sending (from PC) ASCII Value STX 02h Start byte 0-9 30h-39h 4 byte unit address. In range 0-9999 R 20h-7Eh 1 byte command type. r read, w write or m misc I 20h-7E 1 byte indicator of internal data block ABC 20h-7Eh Command –three byte mnemonic ; 3Bh Separator PQR 20h-7Eh Data –Optional, variable length ; 3Bh Separator X 20h-7Eh Sum Check ETX 03h End byte
87 15.3 Packet Structure Reply (from controlled device) ASCII Value STX 02h Start byte 0-9 30h-39h 4 byte unit address. In range 0-9999 Z 20h-7Eh Status BYTE PQR 20h-7Eh Data –Optional, variable length ; 3Bh Separator X 20h-7Eh Sum Check ETX 03h End byte The Sum check byte is the summation of all bytes in the packet, not including the start and end bytes. Higher order bytes are ignored and the final byte result is modified to prevent ASCII control characters being sent. Bit 7 (highest) is forced high. Status byte will indicate command performed OK, or indicate an error. ASCII Meaning 1 All OK E 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
