6. Operating
6.1 Initial conguration
All modules leave the factory with this control over Ethernet interface IP address: 192.168.1.10. In order to avoid conicts
with other IP addresses, it is necessary to perform an initial conguration in the local mode. Subsequently, it will be possible
to access the module via local area network (LAN), either to change the conguration or to check the operating status.
The modules leave the factory with the following control over Ethernet interface TCP/IP conguration:
IP address of the module: 192.168.1.10
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
To access each module, use a personal computer (PC) equipped with an Ethernet card and
RJ-45 cable (CAT-5E or CAT-6). The IP address of the PC/MAC must be congured within
the following range: 192.168.1.2 - 192.168.1.254 (do not use 192.168.1.10, since this is the
IP address of the module to be congured). To start the conguration of the module, open
your web browser and type in the following direction: http://192.168.1.10. The login prompt
will appear on the screen (see Figure 6).
Figure 6. Login window
Access to the module is protected by user name and password. The default user name and password is admin. Enter
the user name and password and click on "Login" button.
NOTE: the default password - admin - can (and must) be changed as explained in the section 6.10.5 "User management".
During initial conguration you need to change the default control interface TCP/IP conguration as explained in the section
6.8 "IP settings".
NOTE: If you are using Internet Explorer Web browser, supported versions are version 10 or higher.
Control interface IP address reset to default procedure: press the "RESET" [5] button for more than 3 seconds. When the
LINK [4] indicator will start blinking, release it. After this operation the control interface IP address will be set to 192.168.1.10,
for more information see section 6.8 “IP settings”.
6.2 General conguration
Initial Web interface screen
The rst screen that appears when the module accessed is the "Main" window, which gives general information on the
device.
Figure 7. General information screen
In the top of each conguration screen you will see a main menu tabs [1]. Using it, you can switch between the dierent
conguration menu. The tab highlighted in yellow shows which menu is active at a given moment. The "System menu" tab
contains several submenu items. Common elements for all screens are module title [2] and login information strings [3].
Pressing on the "Logout" string you can logout from module control.

Device information table
This shows the following data of module:
“Device model”: model of the module.
“Serial number”: serial number of the module.
“Software version”: module software version number.
“Title”: user may assign a title to the device for easier management. Press the button "Change" to modify it. This title will
be written at [2] place. Also it will be visible in other devices, and by computers in network devices (if PC supports SSDP).
"Regions": Device supports several preinstalled regions. The RF channel list depends on which region is selected. Region
can be changed without restarting the device. Just select needed region by pressing “Change” button in “Device information”
table. Additional regions can be installed under request. Contact our distributors for such possibility.
“Software version”: module software version number.
“System time”: current time, synchronized from the TDT table of the input stream or NTP server. Local time oset can be
selected in the System menu/Date,Time.
“Up time”: time passed from last power-up or restart of the module.
Output bitrates table
It displays the output bitrate status of each channel in real time, Horizontal bar shows the percentage of used available
bandwidth in the channel. The 1st number right to the bar shows actual bitrate in Mbps. Next number shows maximum allowed
bitrate in the channel and it depends on modulation parameters. Ensure that actual bitrate would not reach more than 95%
of available bandwidth. Otherwise bitrate overow may occur.
System status table
It represents the following parameters at real time: Processor load in percents, internal temperature in degrees of Celsius,
power voltage in Volts.
Other device in the network
If there are any modules in the network their status and diagnostic information will be displayed as it is in Figure 7 "General
information screen". If modules status is red press the down arrow and diagnostic errors will be displayed. Make sure, that
Ethernet router is congured properly to pass SSDP packets (239.255.255.250:1900 and 239.255.255.246:7900). Also make
sure that all modules are connected to the same Ethernet network.
Diagnostic information table
It displays all module errors and comments (if possible) how to eliminate them.
Figure 8. Diagnostic information table with errors
6.3 RF inputs
Figure 9. Input type selection Figure 10. Input source type = dSCR
The Figure 9 "Input type selection" table consists of the following parameters:
"LNB LO frequency" - the LNB local oscillator lower frequency in megahertz. Use 9750 MHz for the universal converter.
"LNB HI frequency" - the LNB local oscillator upper frequency in megahertz. Use 10600 MHz for the universal converter.
“LNB Power” - power supply of the converter – can be set to “0”, “13V”, “18V”, “13V/22kHz”, “18V/22kHz”.
"Polarization" - the polarization of converter. Can be "Horizontal" or "Vertical".
“Source type” - the LNB types, there are several: Universal, Quadro, DiSEqC, dSCR EN50607, SCR EN50494 - see
Figure 10. dSCR and SCR options are available in "Input 1" only.
7
“Universal LNB” - power supply voltage of the converter is chosen according
to the selected polarization – 18 V Horizontal, 13 V Vertical; the 22 kHz is
set depending on given "LNB HI frequency" "LNB LO frequency" and “Input
frequency” parameters.
For example:
LNB Hi=10,600, LNB Lo=9750, then F=(950+10,600+2150+9750)/2=11,725 MHz.
“DiSEqC” - then DISEQC commands are used to select the satellite. Possible
commands: “Satellite A”, “Satellite B”, “Satellite C”, “Satellite D”, Vertical or
Horizontal polarization.
"dSCR" – rst select source type as shown in Figure 10, then select “dSCR/
SCR mode“ Master or Slave (Master for module which has direct connection to
Unicable multiswitch or LNB and Slave for modules connected by loop through).
If Slave was selected, additionally type the IP address of Master module. All
the modules in the dSCR/SCR group must be in the same Ethernet network.
Next select "SAT input" and "User band", type in frequencies, symbol rate press
“Update” button and observe "dSCR" status.
"SCR" - same as "dSCR", just the user band frequencies must be typed in
manually as shown in Figure 11.
Figure 11. Input source type = SCR
Figure 12. Demodulator settings table
„SAT input“ - a parameter that can switch demodulator o or connect to any available RF input.
“User band” - parameter used in dSCR/SCR switches.
"Modulation standard" - a selection between DVB-S and DVB-S2 standards.
„Input frequency“ - parameter is a frequency of transponder in MHz.
„Symbol rate“ - parameter is a symbol rate of transponder in kSym/s.

6.4. Transport Streams
One input channel at a time can be congured in this page. Select proper channel from the list at „Choose input channel“
combobox. A list of services in the selected channel will appear (see Figure 14 "List of services").
Figure 14. List of services
„List of services“ table shows a list of available services. Icon before the service name indicates service type. Bitrate
of each service is measured in real time. Services that currently are not running will be displayed as grayed. They can be
selected and will be outputted normally when the services starts running. „LCN“ eld is a Logical Channel Number. Every
service can have a „channel number“ and TV will sort channels according to it. Just ensure, that all services in all channels
have dierent numbers. Value "0" means, that LCN for that service is not used at all and TV will sort these channels according
to it’s own rules.
Services can be passed to any output number, independing on the input demodulator number.
BISS scrambled services have a checkbox for descrambling.
Press onto sign and service information will be extended (see Figure 15 "Service details").
Figure 15. Service details
Service title and provider can be edited (multilanguage character support). „Scrambled ag“ will be inserted into SDT
(Service Description Table). Unchecking this checkbox will not descramble the content. It only carries information about the
scrambling status of the service.
BISS scrambled services have a BISS key input eld "BISS Code". Enter the BISS code (12 or 16 characters) in
hex format.
Individual streams can be disabled as well. PID number can be remapped manually by selecting checkbox “Other PID”.
Keep in mind that PID must be unique, otherwise PID remapping is done automatically.
Press onto „Update“ button to save changes and execute.
9
NOTE: If transparent mode is selected (tdx480, tdq480 only), all services of transponder will be passed to the output, including
original PAT, SDT, PMT, EIT, CAT, NIT tables. All changes that were made to these tables (new titles, LCN) will be disregarded.
No more than 95% of output bandwidth usage is recommended, otherwise bitrate overow might occur.
6.5. NIT
Several tables related to NIT generation exist in this section. Figure 16 "Global TS parameters" describes following TS
parameters:
Figure 16. Global TS parameters
“Network ID”: is unique number within the geographical region dened by the “country code”. For a cable network usually
this is a single country code plus 0x2000 (8192). If there are more connected modulators in the network, they must have
the same Network ID.
Proper value depending on your country and operator can be found here:
http://www.dvbservices.com/identiers/network_id?page=1
“Private data specier (in hex format)”: can be inserted in the NIT table for proper LCN description. This value is described
in TS 101162 specication. NorDig standard requires 00 00 00 29 value, UK should use 00 00 23 3A value.
Other options can be found here:
http://www.dvbservices.com/identiers/private_data_spec_id?page=1
The parameter will not be inserted into NIT if value is set to zero.
„Network name“ is the name of the network.
The 2nd table in the page describes Transport stream ID and Original network ID of each channel (see Figure 17). Each
stream in a network must have unique ID, called „Transport stream ID“. An Original_Network_ID is dened as the “unique
identier of a network”. It can be linked to NetworkID or used value from this location:
http://www.dvbservices.com/identiers/original_network_id?page=1
Figure 17. Transport stream and original network IDs
10
Every channel in the network must be described in NIT. Otherwise TV automatic channel tuning function will not nd all
channels. All other modules in the network will be monitored via standard SSDP protocol. NIT tables will be regenerated if
any change is detected in other modulators with the same Network ID. Make sure, that Ethernet router is congured properly
to pass SSDP packets (239.255.255.250:1900 and 239.255.255.246:7900). Also make sure that control ports of all modules
are connected to the same Ethernet network.
6.6. RF outputs
Transmodulator has one (tdx440, tdq440) or two (tdx480, tdq480) independent groups of four adjacent channels.
Figure 18. DVB-T output parameters (tdx480)
"Output frequency“ parameter can be entered manually or selected as a channel from combobox. Channels that can be
selected from the list depend on which region is selected. If you need any other frequency – select “Manual” and type the
needed frequency. Frequency step is 0.1 MHz. „Enable“ checkbox will enable channel to the output. Global attenuator can
be entered up to 15 dB. Also there is individual precise attenuator up to 2.5 dB in step of 0.5 dB.
Press „Update“ to change settings. In case, if any modulation parameter was changed, both channels will be restarted
with new settings. Exception is „Attenuator“, changes in this parameter will not restart the modulator.
Figure 19. DVB-C output parameters (tdq440)
Figure 19 shows tdq440 DVB-C output settings. In case of tdq480, count of output channels will be 8. The step of RF
channels can be selected to one of these values: 7.0, 7.5, 8.0, 8.3, 8.5 MHz. Actual bandwidth of each channel depends on
the symbol rate, and can be calculated as SR x 1.15 (1.15 here is roll o factor of 15%). Symbol rates of all channels must
be the same, from the range of 3500..7200 kSym/s.
Output channel enumeration depends on the region selected from the main page. However, it's allowed to enter any
frequency you want in a range of 100..858 MHz in all devices.
Only the rst output frequency/channel of the group can be entered by the user. Other frequencies will be calculated
automatically according to the selected step/bandwidth.
