Chapter 3

System setup

In this chapter, we will install and configure the modules. This can be divided into 3 steps:

1. Installation of the modules: In this step the GUI gives a USB-address to themodules.

2. Setup of the modules: Configuration of the LNB, multiplexes, extra module options.

3. Configuration of the streams: Configure the programs to be distributed.

3.1 Installation of the modules

• Go to the INSTALLATION menu. You get a rack overview (Figure 3.1), but all slotsappear as empty.

Figure 3.1: Installation of the modules: empty rack

10


12/36

• Click on INSTALL to start the installation. Your screen should look like Figure 3.2.The GUI is now ready to install all the modules.

Figure 3.2: Installation of the modules: choose the rack

•

Choose the rack number (by default RACK 1) and press NEXT.

Figure 3.3: Installation of the modules: install all modules

11


13/36

• Start with the first module (left side of the rack), and be sure all other modulesare disconnected from the PC! Press PROGRAM and wait for the installation to

finish.

Figure 3.4: Installation of the modules: finish the installation

◦ If more than one modules are installed in the rack, connect the next module, andagain press PROGRAM. Repeat this step untill all modules are programmed.

◦ Press FINISH

◦ Press OK

12


14/36

• Now, all the installed modules appear in green (Figure 3.5). Inside the green boxes, thetemperature of the modules is shown.

Figure 3.5: Installation of the modules: all modules installed

Notes:

– Figure 3.5 gives an overview of the complete system.

– After the installation, an USB hub may be used to control all modules at once.Be sure you connect the USB hub AFTER the installation!

– If the modules don’t appear as green right after installing them, please wait amoment until all modules are reinitiated.

3.2 Setup of the modules

In this step, we will configure the inputs (LNB/AV settings) and outputs (MUX settings) of the modules.

• Go to the SETTINGS menu. You get an overview of the installed modules (Figure 3.6).Click the module to setup.

Figure 3.6: Setup of the modules: choose the module

Follow one of the following steps, depending on the type of module:

14


16/36

1. ProQuad, ProTwin, ProSingle (Ref. 5103Q, 5103T, 5103S)

• Go to the LNB tab to configure the LNB settings (Figure 3.7)

Figure 3.7: Setup of the modules: LNB settings

◦ BAND: Name of the satellite band.

◦ VOLTAGE: 13V/18V

◦ TONE: 22 kHz ON/OFF

◦ DiSEqC: A/B/C/D

◦ Ext. Voltage: Add 1 V (compensation for long coaxial cables)

• Configure the used inputs and press on APPLY to save the settings. Press PRESETto reset all fields.

15


17/36

• Go to the DVB-T tab page to configure the multiplexes (Figure 3.8).

Figure 3.8: Setup of the modules: DVB-T output settings

◦ FREQUENCY: Center frequency of the DVB-T channel. The output canbe configured in the VHF and UHF bands (47 MHz - 862 MHz).

◦ GAIN: Define the output level in the range -40 dBm to -25 dBm (68 dBµVto 83 dBµV).

◦ CONSTELLATION: QPSK/16-QAM/64-QAM

◦ CODE RATE: 1/2, 2/3, 3/4, 5/6, 7/8

◦ GUARD INTERVAL: 1/4, 1/8, 1/16, 1/32

◦ STATE: ON/OFF

◦ BANDWIDTH: 6/7/8 MHz

◦ SPECTRAL INVERSION: ON/OFF

•

Press APPLY to save the settings. Press PRESET to reset all fields.

Notes:

- Only the frequency of the first MUX can be set. The frequency of the othermuxes is automatically set. All muxes are adjacent, so the center frequency of MUX 2 is that of MUX 1 + 8 MHz (8 MHz is the bandwidth of 1 MUX).

- If more more than one module is used, make sure the frequencies of the differentmodules don’t overlap!

16


18/36

• Go to the MPEG tab page. On this page you can set the numbering of theprograms.

Figure 3.9: Setup of the modules: MPEG settings

• The TSID and LCN tables can be filled in automatically by pressing on PRESET,followed by APPLY. This ensures the channels are adjacent and don’t overlap.

• If wanted, the fields can be changed:

◦ TSID: Transport Stream IDentifier

◦ LCN: Logical Channel Number

◦ CAS Forwarding: Forward the Control Access System tables (CAT, EMM,ECM) to descramble the programs with a set-top box.

CAT: Conditional Access Table

EMM: Entitlement Management MessageECM: Entitlement Control Message

• Press APPLY to save the settings. Press PRESET to change the settings back todefault.

3.3 Configuration of the streams

In the previous steps, we configured the modules. Now we are ready to configure the streams.This means we will set the appropriate settings for the tuners and choose the programs tostream.

• Go to the CONFIGURATION menu and choose the module to configure.

Figure 3.13: Configuration of the modules.

21


23/36

1. ProQuad, ProTwin, ProSingle (Ref. 5103Q, 5103T, 5103S)

• Select the tuner to configure.

Figure 3.14: Configuration of the modules: configure the tuners

◦ Band: Select the satellite band. The names in this list are configured in theprevious section (Setup of the modules).

◦ Frequency: Select the frequency of the transponder.

◦ Symbol rate: Select the symbol rate of the transponder (20000/22000/27500kbaud).

25/36

• Select the MUX to be configured.

• Drag and drop the programs in the desired MUX.

Figure 3.16: Configuration of the modules: drag and drop the programs

• The programs that are streamed will be highlited in green. If you check the CAMfield next to a stream, this stream will pass trough the CAM module. If the stream

is scrambled, the icon appears next to it. If the stream is descrambled, theicon appears.

• To stop the streaming of a certain program, click OFF, next to that program. Theprogram will stay in the list, but will not be highlighted in green anymore.

• To remove a program from the list, press on the clear button next to it: .

Notes:

- Depending on the bandwith of the chosen streams, you can select up to 8streams per MUX. Some streams use a lot of bandwidth and reduce thisnumber. . .

- You cannot drag and drop 2 times the same program.

- T1, T2, T3, T4 before the name of the streams indicates the number of thechosen tuner.

24


26/36

The number of programs depend on the bandwidth of the chosen streams. The totalbandwidth of the streams is shown in the Output Bitrate bar graph. When the bar is

green, other streams can still be added (up to 8). When the bar is orange, we are onthe limit of a bitrate overflow:

Figure 3.17: Output bitrate on the limit of overflow.

When the bar is red, there is a bitrate overflow. Remove a program to stabilize thesystem!

Figure 3.18: Output bitrate overflow.

2. AV encoder module (Ref. 5130)

Figure 3.19: Configuration of the 4 AV streams

• Signal locked: If this icon is green, the AV stream is locked.

• SOURCE NAME: Name of the AV-source (name is given in the setup).

• STREAMING: Click YES to enable the streaming of the AV-source.

The output bitrate is shown, but will normally not exceed 28 Mbps.

Extra functionalities

4.1 Save configuration

The settings and configuration can be saved. This allows for easy reproduction in otherheadends with the same configuration. It’s also very convenient after a module upgrade.

Go to the CONFIGURATION menu and select the module. Press the icon. A popupappears, where you can choose the file location.

Figure 4.1: Save the configuration.

Browse to the desired file location, type a filename and click save .

27


29/36

4.2 Restore configuration

Saving the configuration saves both the settings and the configuration. The restore on the

other hand is not common. Go to the SETTINGS menu and click on the icon. Browse tothe location of the saved .xml-file and open it.

Figure 4.2: Restore the settings.

This only restores the SETTINGS of the module. To restore the configuration, go to theCONFIGURATION menu and repeat the same procedure.

4.3 Reset

To reset the configuration, press the icon. A popup appears, asking if you want to clearthe configuration. Press Yes to proceed.

Figure 4.3: Clear the configuration.

4.4 Alarm monitor

The alarm monitor logs the alarms of the modules in the rack. When a module is in alarm(red LED on the front of the module blinks), go to the ALARM MONITOR menu.

Figure 4.4: Alarm monitor.

Choose the rack and module and click VIEW . A list with the alarms appears on the screen.

Save the alarm logs as a .txt-file.

Print the list of alarms.

Clear the list of alarms.

4.5 Upgrade

The version of the GUI must be compatible with the version of the modules. Upgrade of the modules is thus accompanied with a GUI upgrade on the PC. The latest release of theGUI can be found on the Johansson website: http://www.johansson.be/en/downloads/software.html

• Log in with your username and password and download the latest Digital ModularHeadend software.

• Use a decompression application (like WinRar) to unzip the folder and install thesoftware. Previous versions may be overwritten.

• Open the DMH software and log in using the service account.

• Navigate to the UPGRADE menu.
