View of the encoder
The included accessories The MD-330 R81713 module has been designed for use in the MMH-3000 headend (in the Base Unit UC-380 R81700). This encoder converts analog video/audio signals coming from analog cameras, video players etc. into MPEG-2 coded transport streams. The transport streams can then be fed into the TRX-360 R81709 DVB-T modulator (COFDM) and distributed in a RF network as channels in the DVB-T multiplex. The encoder has three composite video and three stereo audio inputs. The signals from the inputs are converted into MPEG-2 TS streams available at three individual MPEG2 TS outputs. The outputs are to be connected (via included ribbon connectors) to the inputs of the TRX-360 R81709 DVB-T modulator (the modulator can simultaneously process signals from another encoder or other modules of the MMH-3000 headend equipped with MPEG-2 TS outputs). The MD-330 R81713 encoder, similarly to all components of TERRA headend, can be configured using free Terra Link or paid CMH Master R81706 software.

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.
