The Multiswitch unit connects to a Quattro LNB (default configuration) or two Wideband LNBs to support reception from 2 satellites and offers a Terrestrial input port to connect a terrestrial antenna for reception of UHF/DAB/radio broadcasts. The terrestrial signal can be amplified through a dedicated ON/OFF switch and is combined over each of the 8 output ports. The output ports operate in either dCSS/SatCR or Universal (Legacy) mode.

The Multiswitch unit can be powered through a DC input port, any of the trunk output lines or from the STB output ports (typically using a power inserter device). In typical cascaded MDU installations, the DC voltage supplied over the DC in or trunk output lines is passed through to the trunk input lines in order to power the LNB and the ‘STB DC pass to LNB trunk’ switch must be set to OFF.

To help the installer ensure at the time of installation that the unit’s power supply is sufficient to support a full load in the future i.e. 8x STBs with all User Bands activated, the Multiswitch features a special power diagnosis test mode that is triggered automatically upon unit startup.
During this 15 second test, the Multiswitch simulates operation with full load and will light the power-diagnosis led in green if the unit is supplied with sufficient power or in amber if not. A status led, located next to each output port, indicates the operating mode of the port (Legacy=solid green, dCSS = blinking green, Power diagnosis=blinking red/green).

The configuration of the Multiswitch can be customized for different installation circumstances where parameters like LNB type (Quattro or Wideband), the frequencies and bandwidth of the User Bands as well as others can be programed using Inverto’s SatPal Controller or Unicable II Programmer*.
