The included accessories
Terra RT-316 R81707 is a "master" module for receiving DVB-T OFDM signals (MPEG2/H.264, FTA multiplexes) and distributing them as MPEG2/H.264 transport stream to a "slave" module e.g. DM-316 R817121. One module receives a whole multiplex, of which one program can be selected for conversion to analog PAL channel.
Other channels from the multiplex can be decoded from the MPEG2 transport stream by "slave" modules DM-316 R817121. The modules distribute them in the RF network as analog PAL channels.
The set(s) of the modules are especially demanded by hotels, hospitals, sanatoriums etc. with multiple analog televisions in use. In such cases it is uneconomical to replace all the receivers to DVB-T ones, or even install individual digital tuners. The MMH-3000 headend is a good alternative to the high costs of replacing all the TV sets or buying many set-top boxes.
Example use of the MMH-3000 headend for conversion of digital DVB-T signal to analog PAL channels
(8 channels from two digital multiplexes)
The module, similarly to all modules used in MMH-3000 headends, is configured with free Terra Link utility or commercial CMH-Master application software R81706.

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.
