Dielectric Rolls Out A SNMP-Enabled Dual RF Switch Controller

0

In a preview of another big Las Vegas event, Dielectric has introduced a new Dual RF Switch Controller to the market that is designed to simplify local and remote control of transmission systems, with its public debut scheduled for the 2020 NAB Show.


The new DRFSC device integrates SNMP and secure web-based capabilities to streamline the management of waveguide and coaxial transfer switch activation for modern TV and radio transmitters. Benefits include plug-and-play adaptability to accelerate installation, streamlined hardware requirements, and networked status monitoring with richer data sets.

Powered by Burk Technology, the supplier of remote monitoring and control systems, the DRFSC can control up to two, four-port RF switches to provide flexible RF routing in systems with auxiliary transmitters and/or antennas. Users can locally activate control applications from its front panel, or remotely through a web browser interface. Burk’s specialized Plus-X protocol is also integrated, enabling connectivity to Burk’s ARC Plus remote control system via a network connection. This allows engineers to centralize DRFSC functions with other control and monitoring applications.

The DRFSC’s integrated SNMP control differentiates the unit from other RF switch controllers on the market. SNMP is a universal networking protocol integrated with most transmitter systems currently available. The new DRFSC can now take advantage of this widely used interface, providing a common interface protocol. Installation is straightforward and an intuitive touchscreen-enabled configuration process enables installers to setup and deploy the system in two hours or less.

The DRFSC provides additional protection through its ability to control transmitter interlocks as switches change position. This prevents damage by ensuring that RF energy is turned off when RF switches are commanded to move to a new position.


Dielectric will demonstrate the controller at its 2020 NAB Booth (C2622) from April 19-22 at the Las Vegas Convention Center.
