7. Operating
7.1 Initial conguration
All modules leave the factory with this control: 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 local mode. Subsequently, it will be possible to
access the modules via the local area network (LAN), either to re-programme it or to check its operating status.
The modules leave the factory with the following Control 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 prompt
Access to the site 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 7.7.5.
During initial conguration you need to change the default control interface TCP/IP conguration as explained in the
section 7.4.
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, user name and password set to admin.
7.2 General conguration
Initial Web interface screen
The rst screen that appears when the module accessed contains 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 menus. The tab highlighted in yellow shows which menu is
active at a given moment. The "System menu" tab contains several submenu items.
Also common elements for all screens are module title [2] and login information strings [3]. The module title can be changed
after pressing the "Change" button in the "Device information" table. Pressing on the "Logout" string you can logout from
module control.

In the "Diagnostic information" table all module errors and comments how to eliminate these errors are displayed.
Figure 8. Diagnostic information table with errors
7.3 RF input/output settings
This screen consists of six tables: "RF input", “RF output”, "List of services", "Input status", “RF output status”, “Description
of other streams in the network”. The "RF input" table is used to congure parameters corresponding to the input satellite
transponder (tdx410C module), terrestrial or cable transponder (ttx410C module). In the "List of services" table the list of
services, available in the input transponder is displayed. In the "Input status" table you can see real time status of the input
section. In the "RF output status" table you can see real time status of the output section.
The "RF input" table is dierent according to the input signal of module.
7.3.1. RF input table
Figure 9. The "RF input" table of the tdx410C module
The „RF input" table (Figure 9) for tdx410C module 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 voltage” – power supply of the converter – can be set to “O”, “Auto”, “13V”, “18V”, “13V/22kHz”, “18V/22kHz”. If
“Auto” is selected, power supply voltage of the converter is chosen according to set the polarization – 18V Horizontal, 13V
Vertical; if the “Frequency” of the satellite exceeds the value F=(950+LNB Hi+2150+LNB Lo)/2, the 22 kHz signal is switched
ON and “LNB Hi freq.” is selected.
For example: LNB Hi=10,600, LNB Lo=9750, then F=(950+10,600+2150+9750)/2=11,725 MHz. When power supply of
the converter is set to value dierent from "Auto." to "LNB HI frequency", “Satellite” and "Polarization“ rows are disabled
and the "LNB LO frequency" value is used for IF frequency calculation.
“Satellite” – DISEQC command is used to select the satellite when the switch that supports DISEQC protocol is present.
Possible commands: “None”, “SAT A”, “SAT B”, “SAT C”, “SAT D”.
"Polarization" - the polarization of converter. Can be "Horizontal" or "Vertical".
“Frequency” – the frequency of the satellite transponder in megahertz.
“Symbol rate” – the symbol rate of the satellite transponder in kilo symbols per second.

The checkboxes in the "Descramble" column are used to select services for descrambling by CA module. Several services
can be selected, if the module supports simultaneous descrambling of several services.
The "Descrambling status" icon meanings: - service is descrambled successfully, - service is not descrambled.
7.3.4. Detailed service information
Press the icon at the start of the list of services line. The detailed service information table will appear:
Figure 15. Detailed service information
This table is used to see the detailed service information and select individual streams for descrambling and output stream.
The following service information is shown in the table: service title, service provider, service id, PMT (program map table)
PID, types and PID-s of service streams, PCR (program clock reference) PID, New service title, New service provider, LCN
(logical channel number). After checking the "Descramble" checkbox of service line, all streams of this service are included
in a descrambling list of the CA module. Unnecessary streams can be deselected from the descrambling list by unchecking
corresponding "Descramble" checkboxes of streams. Close the table by clicking on the icon. "New service title" - the
name given to the service. The name that the service has on the input transport stream is the default name. Also this name
will be used as the output service name."New service provider" - enter the provider name of the output stream. This name
will be used in the SDT table.LCN: Logical channel number for outputted TS can be placed.
NOTE: PMT tables are not regenerated, so even if service is descrambled, some TV's might show "service scrambled"
message, because CA descriptors are left at PMT table.

Once the dierent data values have been entered, click on Update to conclude the
Output settings.
Figure 16. RF output setting table
7.3.6. TS output
Several tables related to NIT generation exist in this section. „Global TS
parameters“(Figure 17) describes following TS parameters:
“NetworkID” is unique 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 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. Valid value
for each operator can be found here:
http://www.dvbservices.com/identiers/private_data_spec_id?page=1
„Network name“ is the name of the network.
Figure 17. Global TS parameters
9
Also you can change Transport stream ID and Original network ID, 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
In case of transparent mode, Fields in Figure 18 will not be used! These values will be the same as in input transport
stream. Also all services will enabled (Column „Enable“ will be greyed in Figure 13).
NOTE: If Transport stream ID or Original Network ID is changed (from original ones), the EIT/EPG will not be available,
because EIT is not regenerated!
Very important part in this page is the 2nd table, where other streams in the network can be described (see Figure 18).
Figure 18. Streams in network
Every channel in the network must be described in NIT. Otherwise TV automatic channel tuning function will not nd all
channels. So, if there are more modulators in the network, all channels must be included in this table. If there are more
devices manufactured by Terra, which are controlled via Ethernet, all broadcast information can be captured automatically
by adding its IP address and pressing „Load“ button. In case if the frequency was added manually already, that record will
be updated. Otherwise, a new record will be inserted.
7.4. IP settings
This screen (Figure 19) consists of three tables: "Control interface IP parameters", "Time parameters" and "IP status".
The IP parameters tables are used to congure Ethernet connection parameters. In the "Time parameters" table a local time
oset can be set. In the "IP status" table current status of Ethernet interface is displayed.
Figure 19. IP settings screen
The description of the "IP parameters”
"MAC Address" - the physical address of the module's Ethernet network card is displayed automatically.
"IP Address" - enter the IP address that you wish to assign to the module. This address must fall within the range of local
network addresses.
"Subnet mask" - enter the local network mask.
"Gateway" - enter the IP address of this gateway. This information is only required if you want to access the module from
the Internet.
7.5. CAM settings
This screen consists of three tables: "CA module monitor", "CA module information" and "CA module menu". In the "CA
module monitor" table CAM restart function in case of descrambling error can be enabled. It is recommended to turn o this
option if inactivated conditional access card has been inserted.
The content of the remaining tables depends on the inserted CA module.
10
Figure 20. CAM settings screen
In the CA module information table general information about inserted CA module is displayed. When there no CA module
inserted, in the "Status" line is a 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 an example, above "CA module menu" table shows the menu for a particular CAM. Click on the corresponding band
to access dierent options. Click on the "Back" button to return to previous menu, click on the "Home" button to return to
start menu.
7.6. SNMP settings
This menu tab contains the SNMP conguration table.
The description of the "SNMP conguration" table rows.
"Read Community" - community name acts as a password that is shared by multiple
SNMP agents and one or more SNMP managers. The "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" - IP addresses of hosts with SNMP managers, where TRAPS
will be send.
