The transmodulator can be used as a stand alone unit - headend with redundant power supply (PS) to increase reliability of supply voltages. S3C32VB – headend with 32 DVB-S/S2 input channels and 16 agile DVB-C output channels. S3C32WB – headend with 32 DVB-S/S2 input channels and 32 agile DVB-C output channels.

Initial configuration Devices leave the factory with this control over Ethernet interface IP address: 192.168.1.10. In order to avoid conflicts with other IP addresses, it is necessary to perform an initial configuration in the local mode. Subsequently, it will be possible to access the device via local area network (LAN), either to change the configuration or to check the operating status.
Device information table This shows the following data of device: “Device model”: model of the device. “Serial number”: serial number of the device. “Software version”: device software version number. “System time”: current time, synchronized from the TDT table of the input stream or NTP server. Local time offset can be selected in the "IP settings"...

Figure 7. “Input 1” table “Source types = SCR” “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.

5.4. Transport Streams One channel at a time can be configured in this page. Select proper channel from the list at „Choose input channel“ combobox (see Figure 11 “Transport streams page”). Figure 11. 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.

SSDP packets (239.255.255.250:1900 and 239.255.255.246:7900). Also make sure that all devices 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 filled manually (Figure 16).

5.7. RF outputs Headend has 16/32 independent and agile channels. "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.
5.8. SNMP settings Figure 18 "SNMP settings" table is located in “IP parameters” tab. The description of the SNMP configuration parameters: "Read Community" - community name acts as a password that is shared by multiple SNMP agents and one or more SNMP managers. "Read Community"...

5.11 System menu This menu tab contains following submenu items: “Event logs”, “Export parameters”, “Import parameters”, “Firmware upgrade”, “User management”, “Restore defaults“, “Restart the device“, “Auto Restart“, “Time, Date”, “Language”. Mouse over to show the list of this submenu. 5.11.1 Event logs Various important events, errors, warnings will be logged into the system, see Figure 21 "Event logs".
Figure 23. Firmware upgrade 5.11.5 User management User may change a password here. Length of the password is up to 16 symbols. Type current password and double enter new password to change it. If logged in user has admin role, new users can be added (see Figure 24 "User management"). Figure 24.
5.11.8 Auto Restart Enable "Auto restart" to schedule periodical restart. Fill in "Scheduled restart time" to restart device on the particular time. The restart will occure every day on speciefied time. 5.11.9 Date, Time System time can be configured manually or taken from NTP server (only if device can access NTP server). Also there is an option to select the time source from TS as shown in the Figure 25.
