The IDLU-UST110-CUO4O-32P is a small size cascadable Unicable II® Multiswitch with 4 auto-detect output ports, each supporting Unicable II® or Legacy functionality. The Multiswitch unit can be connected to a single satellite Quattro LNB (default configuration) or to two Wideband LNBs to support reception of 2 satellites. A Terrestrial input allows to connect a terrestrial antenna for reception of UHF/VHF/DAB/radio broadcasts. The terrestrial signal can be amplified (On/Off switch) and is combined over each of the 4 output ports. By default, each output port functions in Legacy-Mode and can be controlled through 13 V/18 V + 0 kHz/22 kHz signals or DiSEqC 1.0/2.0 commands. The port switches to Unicable II® mode automatically upon receiving a EN 50494/EN 50607 command and provides 16x dynamic User Bands (refer to the product technical specifications for the default settings of the 16 user bands).
The Multiswitch unit can be powered through a “DC in” port, any of the “Loop-through” ports or from the STB output ports (typically through a power inserter device). In typical cascaded MDU installations, the DC voltage supplied over the “DC in” or “Loop-through” output lines is passed through to the trunk input lines to power the LNB(s), 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, the Multiswitch features a special power diagnosis test mode that is triggered automatically upon unit start-up. During this 15 second test, the Multiswitch will operate in full load and will light a 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 of the output ports, indicates the operating mode of the port (Legacy = solid green, Unicable II® = blinking green, power diagnosis = blinking red/green).
