DVB-S/S2 Receiver (CI, MPEG2 TS output): Terra RDC-311 (for MMH-3000 headend)
The RDC-311 R817102 module is mounted in the base unit (UC-380 R81700) of the MMH-3000 headend.
The module receives and converts DVB-S/S2 (QPSK/8PSK) signals into MPEG2 TS (transport stream) that can be further used e.g. by DVB-T modulator TRX-360 R81709. One module converts a whole satellite transponder.

The RDC-311 R817102 module (in connection with TRX-360) is intended for creating a DVB-T multiplex - in the case of conversion of satellite channels into analog PAL channels the suitable choice is RDC-316 R817101.
The device has been equipped with PCMCIA slot for a Common Interface module, which allows for reception and decoding of encrypted channels.
Sets of RDC-311 R817102 and TRX-360 R81709 modules are used to convert satellite channels into DVB-T multiplexes distributed in larger antenna systems. Such systems are often used in hotels, providing high-quality TV channels, including HD ones.
The set of RDC-311 R817102 and TRX-360 R81709 modules converts satellite channels into a DVB-T multiplex. Each of the RDC-311 R817102 modules receives a selected satellite transponder. The whole transponder is fed to the TRX-360 R81709 module allowing the administrator to select channels that are to be placed in the DVB-T multiplex. The TRX-360 has six the MPEG-TS inputs. The administrator should remember about the maximum bitrate at the output of the DVB-T modulator in the TRX-360 module (ca. 31 Mbps). It translates into 7-8 SD channels.
The principle of selection of the Terra MMH-3000 modules for converting DVB-S/S2 broadcasts to DVB-T multiplexes is as follows:
  • the number of the RDC-311 R817102 modules is the same as the number of received satellite transponders,
  • the number of TRX-360 R81709 modules is the same as the total number of SD channels divided by 8; one TRX-360 can operate together with maximum six RDC-311,
  • the number of the UC-380 R81700 base units is equal to the total number of all modules divided by 8.

Electrostatic discharge caution

The module contains electrostatic sensitive components. To minimize electrostatic discharge, observe the following precautions:
  • Do not remove module from its anti-static plastic bag until you are ready to install it into the base unit.
  • Hold the module only by its front panel.
  • Do not place the module on an unprotected surface. Immediately after you remove the module from the base unit, you must insert it into its anti-static plastic bag.
  • When the module is not in use, keep it in its anti-static plastic bag.
  • Do not ship or store the module or base unit in/near strong electrostatic, electromagnetic or radioactive fields.
