QPSK CI Receiver RDC-313 (QPSK/PAL, for MMH-3000 headend)
View of the device
DM-313 R81712 makes a part of MMH-3000 headend, cooperating with RDC-313 receiver. It decompresses a desired program from MPEG-2 transport stream. If the RDC-313 receiver incorporates CA module, the transport stream is usually unencrypted.
Notice! One module receives one program.
The device has been also equipped with VSB modulator (PAL). Thanks to vestigial side band the modulator allows to utilize adjacent channels. This kind of operation requires balanced output levels of output channels. The differences among individual channels cannot exceed 3 dB.

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.
