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.

• 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

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




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




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

21

2 Advanced Operation

2.1 Central Receiver PC Controller Application Software

Advanced control of the Central Receiver system is available by using the dedicated PC control application.

The PC Control application allows using to configure parameters such as frequency, scrambling key and streaming parameters on the Central Receiver. Additionally the Central Receiver Control application is a powerful tool for monitoring the installed central receiver, monitoring alarms and RF performance.

• The Central Receiver is controlled by the crx_ctrl.exe application available on the CD delivered with the product. Or downloaded from the domo website.

Note: that exact file names may change as software version information is a part of domo file names.

2.2 PC Requirements for operating the Central Receiver PC application

The Central Receiver can be controlled with a connection that is either:

• RS232 connected to the 9 way Dtype ‘Ctrl’ port on the front of the Central Receiver.

• Ethernet IP connected to the RJ45 ‘ETH0’ port on the front of the Central Receiver.

Therefore a PC is required with either an RS232 Serial COM port, or an Ethernet IP port.

Installation of the Central Receiver control programs is as simple as copying it from the CD to a suitable location on the PC. No install shield routine is launched. Note that the controller generates 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.

2.3 Connecting to the Central Receiver

Launch the application by double clicking or using the run command. A window similar to that shown below will be displayed on the PC.

22

Users Connecting with RS232

Should select the RS232 Radio Button, select the appropriate COM Port, and then press the connect button. If connection is achieved the connection status will say Connected if connection fails it will say Not Connected. If connection is not achieved, the user should check the comm. Port, and the cable connection.

Users Connecting using Ethernet IP

Should select the Ethernet Radio Button. Then enter the IP address of the Central Receiver being controlled, the default IP address is 192.168.0.50. The user should then press the connect button. If connection is achieved the connection status will say Connected if connection fails it will say Not Connected.

If the default IP address is unsuitable, then the user should connect using RS232 (described above), and set the unit network parameters shown above. The user should discuss this with the network manager.

• IP Address

• Subnet Mask

• Gateway Address

2.4 Introduction to the Central Receiver Controller

In general on the Central Receiver control application, 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.

Understanding the Status Field

This field is permanently displayed and gives the user instant status on the four receivers within the central receiver.

The alarms have the following meaning:

Alarm Meaning for Receiver X (1 to 4)

Demod Lock Green = demodulation is occurring

Red = No demodulation (signal too weak, or tuned to incorrect frequency)

Reception Green = signal received with zero packet errors

Red = No reception

Decoder Lock Green = video and audio decoders operating fully

Red = video and audio decoders not operating (if this is occurring while reception is green, indicates that the service is scrambled or that the service names do not match)

Using the Control Field

The Central Receiver controller is structured around 7 main ‘Tabs’. These ‘Tabs’ logically divide the function of the unit and are entitled.

Tab Meaning / Use

Global Describes parameters specific to the entire central receiver, such as: software version numbers, quad split control and IP parameters.

Streamer Contains parameters that control the Netstream option, such as streaming bitrate and IP parameters.

Receiver 1 Contains parameters that are specific to receiver 1, such as frequency, encryption key and RF status.




The Global Tab

The global tab describes parameters specific to the entire central receiver. These parameters are shown below.

25

Software Version Numbers

The software version numbers of the entire central receiver and all the individual receivers within are described here.

Unit Status

The internal temperature (-10 to +50 deg maximum) of the central receiver and also the internal voltage (should be approximately 12V) can be monitored here.

Unit IP Parameters

The IP parameters of the equipment can be set using these fields, this will allow the control and connection of the unit over the IP interface (ETH0). These should be set with the advice the network service provider.

Video Monitor Output Control

This parameter controls which video is presented on the monitor/quad video output on the front of the unit. The user can select for this output to display any of the individual receiver outputs, or to display all four outputs as a quad split display.

Remultiplexing Parameters

These parameters control how services are remultiplexed and transmitted over the option Netstream IP or Microwave Relay outputs.

If automatic service renaming is selected, then the central receiver will automatically rename the received services according to the following convention.

The user can modify the prefix, by changing the default away from ‘CRX-‘ in the service prefix field.

If automatic service renaming is not selected, then the user must ensure that all contributing transmitters have different service names and PIDs.

PAL / NTSC configuration

The CRX can be configured to operate outputting video in either PAL or NTSC formats. To switch between PAL and NTSC the user must check that the “Output video standard” setting in Engineering options ->Advanced options->Global is set to the correct video standard. Also check the “Power-up line standard” option in each receiver’s advanced tab. The CRX system supports PAL and NTSC but the two cannot be mixed, so all transmissions into the unit must be the same standard to correctly display the video.

Note: Incorrect setting of the global video standard leads to picture distortion, rolling video and colour loss.

The Streamer Tab

The Streamer function is described in more detail in section 9, Netstream IP Output Option.

The Rebroadcast Tab

The Rebroadcast function is described in more detail in section 10, Microwave Relay Output Option.

27

The Receiver Tab

The Receiver tab describes parameters specific to the entire central receiver. These parameters are shown below.

Configuration Tabs

Each of the four Receivers within the central receiver contains 8 pre-stored configurations.

The configuration contains a complete description of the receiver, including the frequency, encryption key etc. The user can easily swap between configurations by selecting one of the 8 configuration tabs. Changes to a configuration that are made while in that tab are automatically saved to that configuration.

Users can store configurations to file or load them from file using the ‘Save’ and ‘Load’ Config buttons.

Input Signal Bandwidth

If the input signal is domo standard 2.5MHz or 1.25MHz, then the ‘Narrowband’ radio button should be selected. If the the input signal is 8, 7 or 6MHz DVBT, then the DVBT radio button should be selected.

Frequency Parameter

The frequency of operation of the receiver is set by typing a frequency into the ‘Input Frequency’ field, frequency is in MHz.

Spectrum Display

28

Scambling Parameters

If the input signal is scrambled, then the appropriate scrambling parameters should be entered. The user should specify the scrambling type from the ‘Descrambling’ drop down menu, then enter the appropriate key by selecting the key button.

RF Status Fields

The various RF status fields give useful RF information for each of the 4 antennas. The data includes RF level (signal strength) and SNR (signal to Noise Ratio) for each antenna input.

Typically:

RF levels of –30 to –80dB and SNR levels of 24 – 12dB indicate a strong signal

RF levels of –80 to –90dB and SNR levels of 12 to 6db indicate a reasonable signal

RF levels of –90 to –95dB and SNR levels of 6 – 3dB indicate a weak signal

Spectrum Display

The actual spectrum received on each antenna can be seen in the spectrum display window, for more information on how to interpret this display contact domo for a training course.

3 NETSTREAM IP Output Option

The SOLO4 Central Receiver has an Ethernet Video streaming facility that can be selected by purchasing the option below.

Netstream IP Video Streaming Option

When the Netstream option is installed the SOLO4 central Receiver can be connected to a suitable Ethernet IP Network and will stream the received video and audio services.

3.1 What Type of Network is Required for IP Streaming

The SOLO4 Central Receiver Netstream option will stream the video and audio services received on its input onto the Ethernet IP output.

The Ethernet IP output connector is labelled ETH0 and is 100BaseT compatible.

The ETH0 RJ45 output connector must be connected to a network of suitable capacity, typically this is a private LAN. The capacity required is the aggregate of the bitrate of the incoming services. Typically the bitrate will be a minimum of 3Mb/s and a maximum of 20Mb/s. Therefore a Network of at least this capacity is required, these kinds of capacity are only available on Private LAN networks.

Note: The high bitrate requirements of streaming video mean that public networks such as 3G or the internet will not be suitable.

Note: The streaming video format is Multicast UDP streaming, users should ensure with their network provider that Multicast UDP streaming is enabled on the routers and switches of the network.

3.2 How do I control the IP Streaming Option

The IP Streaming option is controlled from the ‘Streaming Tab’ of the PC Control application. A screen shot of this option is shown below.

30

To enable streaming the user should take the following steps.

• Select which services should be streamed by individually ticking the boxes in the ‘Channels to be streamed’ field, each channel corresponds to the output of a Receiver.

• Set a suitable streaming bitrate (this must be an aggregate of the bitrate of the selected services). When a suitable bitrate is selected in the ‘Streaming Bitrate’ field the ‘Bitrate OK’ alarm will be green. This should be an iterative process, because the bitrate should not be set excessively high, to minimise pressure and cost on the network.

• Enable streaming by setting the ‘Streaming enable’ field to On

3.3 How do I decode the Streaming Video Services

Domo provides two products for decoding streamed video and audio services.

1. IP Software Decoder, this is a PC based software decoder that will display streamed video and audio services in a ‘window’ on a PC. This application is explained in more detail in section 11.

2. IP Hardware Decoder, this product is a rack mounted hardware product with IP input and video and audio outputs. For more detail on this product (code NETIPH) contact domo.

4 Microwave Relay Output Option

The SOLO4 Central Receiver has a Microwave Relay Output Option that can be selected by purchasing the option below.

SOLCRXT-115140 Microwave Relay Downlink option LBand

Frequency: 1.15 to 1.4GHz

Signal Level: 100mW 20dBm

Modulation: DVB-T 8/7/6 MHz and 2.5MHz

Tuning Step Size: 250kHz

SOLCRXT-228255 Microwave Relay Downlink option SBand

Frequency: 2.28 to 2.55GHz

Signal Level: 100mW 20dBm

Modulation: DVB-T 8/7/6 MHz and 2.5MHz

Tuning Step Size: 250kHz

When the CRX-Relay option is installed the SOLO4 Central Receiver can be used as a microwave relay.

When used as a microwave relay, the SMA output labelled ‘RF Out’ should be connected directly to an antenna, or to an antenna via a power amplifier. The following factors should be considered when connecting the CRX-Relay Option.

• The use of long cables will reduce the transmitted power level, therefore Power amplifier devices may be required.

• The relay antenna should not be placed close to the CRX receive antennas, to avoid loss of receive sensitivity, filters may be required to ensure this.

Note: domo can conduct site surveys and frequency planning if required.

4.1 How do I control the CRX-Relay Option

The CRX-Relay option is controlled from the ‘Rebroadcast Tab’ of the PC Control application. A screen shot of this option is shown below.

32

To enable the CRX-Relay option the user should take the following steps.

• Select the output frequency by entering a suitable frequency in MHz into the ‘Output Frequency’ tab.

• Select the desired modulation type by entering suitable values in the bandwidth, FEC, Constellation and Guard Interval parameters.

• Select the services that should be rebroadcast, by clicking the appropriate check boxes in the channel selection area. When the bitrate set by the relay modulation parameters is greater than the aggregate bitrate of the selected channels, then the bitrate OK alarm will go green. This should be an iterative process, because the modulation should not be set excessively high, to rebroadcast range.

• Enable the CRX-Relay by setting modulation to ON.

4.2 How do I decode the CRX-Relay Video Services

The domo downlink receiver is used to decode services that are rebroadcast using the CRX-Relay option, contact domo for more information.

5 Video Stream Player

5.1 General Information

The domo video stream player 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, and domo should be contacted to provide a serial number is return for the code offered by the application once installed on the target 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.

The application is launched by double clicking the application icon, which may appear as depicted below.

By default the Install Shield will also place an option in the computers Start menu to launch the application. This will appear as “domo Video Stream Player”.

Note – later revisions of the video stream player may feature different icons or application names.

The domo video stream player 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.

5.2 Decoding Multicast Streams

If the application is started on a PC, which is connected to a network shared by the CRX, then it will present a view of available streams that can be software decoded and viewed on the PC.

34

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:

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:

35

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.

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.

5.1 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.

36

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 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.

5.2 Main decoder window

The main decoder window will appear as follows:

37

The title bar of the window presents the service name and the streams multicast details. Below this 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:

38

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.

39

5.3 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.

5.4 Miscellaneous application options

The main application window has a menu-bar with an Options drop-down menu. This presents the following selections:

40

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.

6.6 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).

Rolling black and white distorted video

Check that the “Output video standard” setting in Engineering options ->Advanced options->Global is set to the correct video standard. Also check the “Power-up line standard” option in each receiver’s advanced tab. The CRX system supports PAL and NTSC but the two cannot be mixed, so all transmissions into the unit must be the same standard to correctly display the video.

9 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.

9.9 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

9.10 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

46

9.11 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

If a new licensable feature is purchased for a unit then new license code has to be programmed into the CRX to enable the function. You may be asked to provide Domo with a serial number file. This can be retrieved from the unit using the following procedure.

10.15 Generating a serial number file

Open the CRX controller application and connect to the unit that you want to re-license and go to the options menu and select the “Generate serial number file” option. This will then bring up a file selection window.

Choose a directory and file name to store the serial numbers in and then hit save.
