Transmodulator with remultiplexing by Televes DVBT / S / S2 COFDM.
What are the main features of the Televes 564301 transmodulator?
- It allows the installer, in addition to configuring the services to the exit, to eliminate a concrete PID of some of the services.
- Configurable and remotely monitorable through CDC.
- They provide useful rate information for each of the input services, showing the occupation of the output channel.
- TWIN output signal fully configurable (2 muxes).
- DiSEqC.
- Configurable CAM position.
- LCN and combined SID issue on both muxes that prevents TV retune when updating the channel grid.
