(May require PSU: 732210)
This 5 wire cascadable multiswitch supports SCR I (EN50494) and SCR II (EN 50607) standards and legacy mode, making the multiswitch compatible with any existing or new set top box.
With 4 satellite inputs (Quattro) and terrestrial input, this multiswitch offers a 2 user outputs, with up to 16 user bands each.
DCFLEX functionality
This exclusive functionality gives the product complete control and flexibility to power the multiswitch from anywhere in the system. The installer will have complete freedom to choose how to power the multiswitch and will be able to choose the best to suit a particular scenario.
This versatility is achieved via a switch (DC LINK) that can be used to isolate or not, from a DC point of view, the multiswitch from the cascade.
Multiple powering options: Directly from a PSU, receiver outputs or line power through the satellite inputs or outputs. Moreover, you could choose to line power only the terrestrial side (TForce) of the multiswitch through the terrestrial inputs or outputs.
It can be easily added to an existing system: You just need to connect a power supply to the multiswitch and isolate it from the power on the cascade (flick the DC link switch). The power of the existing system will pass through the multiswitch unaltered and the dCSS NevoSwitch will only draw power from its own power supply. This will avoid any possible problems created by adding a new dCSS NevoSwitch to an existing system.
Increased safety for the set top boxes connected to the multiswitch, as these are completely isolated from the power in the cascade, avoiding potential issues with the power in the system affecting the end user equipment.
Wide powering range: With voltages from 10V to 20V making it compatible with most of the systems out there.
ECO mode: The multiswitch isolated from the cascade can reduce its power consumption to zero when the set top boxes are turned off and terrestrial is passive. In case TForce is activated, the consumption is only 50mA. This is possible because the multiswitch will also dynamically adapt the way that it’s powered in order to keep its consumption to the minimum. So it will automatically turn off any part of the circuit that is not been used in order to lower its consumption.
DCFLEX
HOW DOES THE DCFlex FUNCTIONALITY WORK? It can be controlled through the following switches:
SAT DC LINK switch (ON/OFF): It isolates or connects the power of the multiswitch to the power available from the cascade (satellite legs).
OFF (isolated from the cascade): The MSW is powered locally (power supply) or from the user output without adding or drawing power from the cascade.
ON (connected to the cascade): The MSW can add or draw (in the case that needs powering) current from the cascade.
TERR. DC switch (ON/OFF): It isolates or connects the power available from the cascade (only terrestrial leg). It can be useful to line power a masthead amplifier or a BOSS antenna, but it can also be use to line power the terrestrial side of other MSWs in the cascade.
RECEIVER POWER switch (ON/OFF): It controls the DC pass from the user outputs towards the multiswitch. You can power the device from the dCSS set top box (if there is enough power available) or a power inserter.
TFORCE
The dCSS NevoSwitch also incorporates the innovative TForce technology, based on MMIC components and developed exclusively by Televes. TForce offers an intelligent terrestrial level adjustment.
You can activate it or not by means of a switch making the multiswitch active or passive on terrestrial.
In active mode, the MSW automatically adjust the terrestrial output level to the optimum level.
In addition, this optimum level is kept balanced in every user output through the dCSS cascade.
