UX25*（dCSS-M20）

Products

The dCSS-M20 LNB enables installations with up to 24 satellite receivers connected over a single coax cable and using the EN50494/EN50607 protocols provides access to unlimited number of transponders (also known as ‘Dynamic’ mode) . Alternatively, it can be configured to deliver a fixed mapping of transponder frequencies to IF frequencies (also known as ‘Static’ mode), allowing an unlimited number of receivers to be connected and providing them access to up to 24 transponders (or more, depending on the bandwidth of the desired transponders) based on digital channel stacking technology.

Key Features

 

- Single board construction for optimum reliability/ small size

- PLL Technology for enhanced frequency accuracy

- Efficient power supply design – low power consumption

- High isolation feed design for enhanced MER performance.

- Surge protection

- Configuration can be updated  via DiSEqC
