Ku-RDC System

The “Ku RDC System” is a compact and comprehensively Down Converter System, fully redundant, fully remote controllable, can supply simultaneously Low & High Band, Vertical & Horizontal (or Circular Left & Right) polarity via RF COAX or opt. Optic Fiber.

The RF Redundancy Switch are protected against power failure thanks to Ultracap Technology.
Thanks to 5 front plug-in module, all parts can be HOT SWAPPED with minimum services interruptions, each module has an indipendent Microcontroller and Memory to clone the New Module installed.

The “Ku RDC System” is controllable via Local display or remotely via WEB GUI & SNMP; through N. 2 Ethernet port and thanks to N. 2 SFP Slot can be connected/controlled also via fiber optic.
