Safety instructions
Installation of the transmodulator must be done according IEC60728-11 and national safety standards.
Any repairs must be made by skilled personnel.
Avoid placing the transmodulator next to heat sources such as central heating components or in areas of high humidity.
Keep the transmodulator away from naked ames.
If the transmodulator has been kept in cold conditions for a long time, bringing it into a warm environment may cause
condensation, so allow it to warm up for no less than 2 hours before powering.
Ventilation should not be impeded by covering the transmodulator, such as newspapers, table-cloths, curtains etc.
Mount the transmodulator in a vertical position only. If installing in a 19” rack system additional forced air cooling fans
may be required.
Always allow 10 cm of free space from the top, front and bottom of the unit to enable any heat to be dissipated.

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 6.11.5 "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" [7] button for more than 3 seconds and 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.
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.

6.4. Transport Streams
One channel at a time can be congured in this page. Select proper channel from the list at „Choose input channel“
combobox (see Figure 21 "Transport streams page").
Figure 21. Transport streams page
A list of services in the selected channel will appear. „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 to 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. If channel numbers are added, but TV does not recognize
it, check the following:
- If TV supports LCN?
- If Network ID and Original Network ID values are valid for the country, which is selected on TV?
„Enable“ dropbox enables the service to the selected output.
“Descramble” checkbox enables or disables descrambling.
Press onto „+“ sign and service information will be extended (see Figure 22 "Service details").
Figure 22. Service details
“Service title“ and “Service 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. “Descramble” checkbox enables or disables descrambling.
"Service type": this is an 8-bit eld specifying the type of the service. The assignment of service type value for a Service
is described in EN 300 468. It shall be coded according to Figure 23.
"Parental control": this selection enables ability to restrict certain content viewable by the user. For example, parental control
eld is set to "Less than 6 years", than all content with maturity rating above 6 years old will be ltered out.

PMT, EIT, CAT, NIT tables, all changes that were made to these tables will be disregarded. No more than 95% of output
bandwidth usage is recommended, otherwise overow might occur.
6.5. NIT
Several tables related to NIT generation exist in this section. Figure 24 "Global TS parameters" describes following TS
parameters:
Figure 24. 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 (hex)”: 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 25). 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 Network ID or used value from this location:
http://www.dvbservices.com/identiers/original_network_id?page=1
Figure 25. Transport stream and original network IDs
Figure 26. Description of other streams in the network
Every channel in the network must be described in NIT. Otherwise TV automatic channel tuning function will not nd all
channels. All 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 all modules are connected to
the same Ethernet network.
NOTE: If in the RF network exists transponders that is generated by old TERRA transmodulators/modulators, the frequencies
and modulation parameters must be lled manually (Figure 26).

6.6. RF outputs
Two adjacent OFDM (DVB-T output) channels can be congured in this section. There is requirement for channels to be
adjacent and sorted by frequency, see the Figure 27 "RF output settings (DVB-T output)". Each channel can have its own
constellation QPSK/QAM16/ QAM64 (DVB-T output), Code Rate (FEC) - there are ve valid coding rates: 1/2, 2/3, 3/4, 5/6,
and 7/8. Guard interval of OFDM signal, available selections:1/32, 1/16, 1/8, 1/4. The bandwidth of DVB-T transponder can
be selected from values 8 MHz and 7 MHz. Cell-ID information is optional.
Figure 27. RF output settings (DVB-T output)
"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, see the 6.11.10 "Regions". 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.
6.7. SNMP settings
Figure 28 "SNMP settings" table is located in “IP parameters” tab.
The description of the SNMP conguration parameters:
"Read Community" - community name acts as a password that is shared by multiple SNMP agents and one or more SNMP
managers. "Read Community" password is used for read-only access to the modules parameters.
"Write Community" - is the password used for read-write access to the modules parameters.
"Enable TRAP" - SNMP traps are alerts generated by agents on a managed device. Check this box to enable TRAP
generation. The module generates traps when the diagnostic message occurs.
"TRAP Community" - is the password used for accessing of TRAPS.
"Host IP #1","Host IP #2""Host IP #3" - IP addresses of hosts with SNMP managers, where TRAPS will be send.
Figure 28. "SNMP settings" table

6.8 IP settings
All device IP settings can be congured here – IP address, subnet mask, gateway,
DNS (Domain Name System), see Figure 29. Starting with software version 1.41,
the “WEB port” number can be customized. Default is 80. You must restart the
device for the port change to take eect. All other IP parameters will be updated
immediately after pressing „Update“ button and redirected to new location.
NOTE: Press the RESET and default IP button [7] for more than three seconds
to set default IP address of the control Ethernet interface (see Figure 1). Ethernet
led indicators "activity" [5] and "link" [6] will start to toggle to inform, that the reset
IP address request has been accepted. Device will be restarted with default IP
address.
To restore all parameters to default values (including password), keep pressing the
button for additional 4 seconds. The green (link) indicator will start blinking after
that time indicating, that a “restore defaults” command has been accepted. Now
the button can be released. Yellow (activity) indicator will light on while resetting
parameters. After that device will restart with all default values.
6.9 E-mail-settings
The device can send e-mail reports if errors were detected. SMTP
protocol is used for that. Figure 30 “E-mail-settings table” shows
parameters related to this feature. “Enable e-mail error report”
checkbox enables error monitoring. All errors within “timeout” period
will be gathered, and send to the e-mail address, provided in “Receiver
e-mail address” input box. Comma separated e-mail addresses can be
used to send report to multiple addresses. The timer will be started as
soon, as the rst error is detected, and stopped when e-mail is sent.
The timer will be restarted again if a new error will appear.
“Sender e-mail address” can be used as authentication in the SMTP
server side.
SSL (SMTPS) protocol is not supported.

Conguration settings and information about CA modules is split into dierent tabs. Most important table “Conguration of
CA modules” can be found in “CAM conf.” tab. In the "Conguration of CA modules" table CAM restart function in case of
descrambling error can be enabled. It is recommended to turn o this option if not activated conditional access card has been
inserted. “CAM settings” and “CAM position” parameters changes the ow of TS. Demod.1 and Demod.2 streams can be
descrambled separately by selecting “Invidual CAM-s” or “Сhained on the line 1” or 2 as shown in Figure 32. CAM position
can be changed from output to input.
For example: “CAM position” is set to “on input” and “CAM settings” is set to “Chained on line #1”. This means that Demod.1
input’s stream travels through CAM 1 followed by CAM 2, then goes to multiplexer and nally to Modulator, see Figure 32.

This menu tab contains following submenu items: “Event logs”, “Export parameters”, “Import parameters”, “Firmware
upgrade”, “User management”, “Restore defaults“, “ Reset the device“, “Time, Date”, “Language”. Mouse over to show the
list of this submenu.
6.11.1 Event logs
Various important events, errors, warnings will be logged into the system, see Figure 34 "Event logs". Each record has
an event type, which can be used to lter particular messages. Just select checkboxes in the „Logs ltering“ table and press
„Apply“. Other messages will be hidden.
„Erase logs“ button will erase all logs from the system.
“Export logs” button forms the le (log.html) which will be downloaded to PC.
Each record has a log time when the event appeared. Refer to 6.11.8 "Date and time settings" for instructions how to
congure time settings.
Figure 34. Event logs
The content of the remaining tables depends on the inserted CA module (refer to Figure 33 "CA information and menu
tables"). General information about inserted CA module is displayed in the “CA module information” table. When there is no
CA module inserted, "Status" line indicates message: "No module inserted" and remaining lines are empty. Otherwise, the
"Status" contains message "Initialized" and remaining lines are lled with information read from the CA module. As in the
example Figure 33 "CA information and menu tables", "CA module menu" table shows the menu for a particular CAM. Click
on the corresponding button to access dierent menu options. Click on the "Back" button to return to previous menu, click

Описание изделия
Устройства представляют собой трансмодуляторы с двумя входными каналами, обеспечивающие прием сигналов
в формате модуляции DVB-S/S2/S2X (модели tdx420C и tdx420) или DVB-T/T2/C (модели ttx420C и ttx420), и двумя
выходными каналами для передачи сигналов в формате модуляции DVB-T/ISDB-T. Устройства предназначены для
цифровой трансмодуляции с обработкой транспортного потока теле- и радиопрограмм, передаваемых методом (FTA)
открытого или кодированного цифрового вещания. В последнем случае необходимо использовать модуль условного
доступа с картой оператора связи. Процессор модулей обеспечивает фильтрацию программ, внесение изменений
в сведения о программах, генерирование NIT (таблиц сетевой информации) и LCN (номеров логических каналов),
перемаркирование временных отметок программ. Все параметры конфигурации могут быть изменены с помощью
Web интерфейса.
tdx420C – трансмодулятор с двумя входными каналами для приема сигналов в формате DVB-S/S2/S2X и двумя
выходными каналами для передачи сигналов в формате DVB-T/ISDB-T и двумя модулями условного доступа;
ttx420C – трансмодулятор с двумя входными каналами для приема сигналов в формате DVB-T/T2/C и двумя
выходными каналами для передачи сигналов в формате DVB-T/ISDB-T и двумя модулями условного доступа;
tdx420 – трансмодулятор с двумя входными каналами для приема сигналов в формате DVB-S/S2/S2X и двумя
выходными каналами для передачи сигналов в формате DVB-T/ISDB-T;
ttx420 – трансмодулятор с двумя входными каналами для приема сигналов в формате DVB-T/T2/C и двумя
выходными каналами для передачи сигналов в формате DVB-T/ISDB-T.
Трансмодуляторы могут использоваться как автономно действующие устройства.
Изделия предназначены для установки и использования внутри помещений.
Инструкция по электробезопасности
