6. Operating
6.1 Initial conguration
All modules leave the factory with this control over Ethernet interface IP address: 192.168.1.10. In order to avoid conicts
with other IP addresses, it is necessary to perform an initial conguration in the local mode. Subsequently, it will be possible
to access the module via local area network (LAN), either to change the conguration or to check the operating status.
The modules leave the factory with the following control over Ethernet interface TCP/IP conguration:
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 congured 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 congured). To start the conguration 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 conguration you need to change the default control interface TCP/IP conguration 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" [6] button for more than 3 seconds. When the
LINK [5] 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”.

6.4. Transport Streams
One input channel at a time can be congured in this page. Select proper channel from the list at “Choose input“
combobox. A list of services in the selected channel will appear (see Figure 14 "List of services").
Figure 14. List of services

Figure 15. 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.
BISS scrambled services have a BISS key input eld “BISS Code”. Enter the BISS code (12 or 16 characters)
in hex format.
“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.
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.
10
“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 di󰀨erent 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”).

11
NOTE: If transparent mode is selected, 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 overow 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 dened by the “country code”. For a cable network usually
this is a single country code plus 0x2000 (8192). If there are more connected modules 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/identiers/network_id?page=1
“Private data specier (in hex format)”: can be inserted in the NIT table for proper LCN description. This value is described
in TS 101162 specication. 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/identiers/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 dened as the “unique
identier of a network”. It can be linked to NetworkID or used value from this location:
http://www.dvbservices.com/identiers/original_network_id?page=1
Figure 17. Transport stream and original network IDs
Figure 18. Description of other streams in the network

12
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 congured 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.
NOTE: If in the RF network exists transponders that are generated by old TERRA transmodulators/modulators, the
frequencies and modulation parameters must be lled manually (Figure 18).
6.6. TS info
Figure 19. TS info
This menu window will help you to easily assign and track LCN numbers of di󰀨erent services and also allows
displaying RF channels bandwidth usage.
“Choose outputs“ - select which RF channel outputs should be displayed.
“Service title” - the list of services which are assigned to the RF output channel.
“Input source” - demodulator which is used to receive and demodulate the RF signal. This demodulator number
shows which service is demodulated by which demodulator.
“Service ID” - unique service identication number.
“LCN” - Logical Channel Number which is assigned to the service.

6.7. RF outputs
Transmodulator has one (tdx441, tdq441) or two (tdx481, tdq481) independent groups of four adjacent channels.
Figure 20. DVB-T output parameters (tdx481)
“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 21. DVB-C output parameters (tdq481)
Figure 21 shows tdq481 DVB-C output settings. In case of tdq441, count of output channels will be 4. 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 (for tdq441, tdq481).
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.

Only administrator (user with a role „admin“) may manage other users.
NOTE: By giving your personal password or user access account for another person, you take full responsibility for all
module settings modications made by that person or anyone else they may give the password to.
6.11.6. Restore defaults
All parameters will be restored back to factory defaults after conrmation. The exception – IP address and users – these
parameters will be unchanged. To restore IP address and system password to system defaults, see “RESET“ button at
section 3 "External view", pos.6.
Several seconds can take to restore all parameters, so be patient.
6.11.7. Restart the device
Device will be restarted after conrmation to do it. This is an alternative to pressing a “RESET“ button when the device
is operating.
6.11.8. Date, Time
System time can be congured manually or taken from NTP server (only if module can access NTP server). Also there is
an option to select the time source from TS as shown in the Figure 30.

6.11.9. Language
Device control panel supports several preinstalled languages. A change of language requires system restart. Note,
that all previously logged records will remain in previous language.
Additional languages can be installed under request. Contact our distributors for such possibility.
6.11.10. Force BISS descrambler
If enabled, this checkbox allows BISS input eld for all services. See Transport Streams (Figure 15.) menu where
you can insert the BISS code.
