16 DVB-S/S2 to 8 DVB-T / ISDB-T / DVB-C / J.83B transmodulators
1. Product description
The transmodulators are designed for digital transmodulation with Transport Stream Processing. Modules processor
enables services filtering, remultiplexing, modifying SI (Service Information), generating NIT (Network Information table),
LCN (Local Channel Number), restamping PCR (Program Clock Reference). All of the configurations can be changed using
the Web Interface.
tdx4168
– transmodulator with 16 DVB-S/S2 input channels and 8 DVB-T/ISDB-T output channels (outputs are grouped
into 2 groups that consists of four neighbouring channels).
tdq4168
– transmodulator with 16 DVB-S/S2 input channels and 8 DVB-C/J.83B output channels (outputs are grouped
into 2 groups that consists of four neighbouring channels).
Transmodulator can be used as stand alone device or as part of the headend station.
The product is intended for indoor usage only.
2. Safety instructions
Installation of the transmodulator must be done according IEC60728-11 and national safety standards.
Any repairs must be made by skilled personnel.
Do not expose this transmodulator to moisture or splashing water and make sure no objects filled with liquids, such as
vases, are placed near or on the unit.
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 flames.
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 plugging into the mains.
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 (see table "Technical specifications" - operating temperature range).
Always allow 10 cm of free space from the top, front and bottom of the unit to enable any heat to be dissipated.
This product complies with the relevant clauses of the European Directive 2002/96/EC. The unit must be recycled
or discarded according to applicable local and national regulations.
Equipment intended for indoor usage only.
This product is in accordance to following norms of EU: EMC norm EN50083-2, safety norm EN IEC62368-1, RoHS norm EN50581.
This product is in accordance with Custom Union Technical Regulations: "Electromagnetic compatibility of technical
equipment" CU TR 020/2011, "On safety of low-voltage equipment" CU TR 004/2011.
This product is in accordance with safety standard AS/NZS 60065 and EMC standards of Australia.

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 module 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 module: “Device model”: model of the module. “Serial number”: serial number of the module. “Software version”: module 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"...
  • Page 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.
