DNF Controls today announced that Rainbow Media Holdings LLC, a subsidiary of Cablevision Systems Corporation and a pioneer in regional and national television programming, is using The Analyst RS422/RS232 Tester to efficiently troubleshoot its complex infrastructure of data cabling.

"We have many different data lines in our facility, with cables running from patch bay to data router to end device," said Peter Primavera, video maintenance specialist at Rainbow Media Holdings LLC. "There are a lot of opportunities for the signal to be lost through errors in wiring or device malfunctions. The Analyst makes it easy to identify where the problem is occurring so that we can quickly correct it and move forward."

Rainbow Media was already familiar with the quality and reliability of DNF Controls' equipment, as it uses ST300 and ST400 VTR controllers and SW32PS port switchers in its Bethpage, N.Y., facility. The company also recently purchased DNF Flex Control Network GTP-32 GPI Tally Processors. For over 25 years, Rainbow Media has created and managed a wide range of television programming, from popular national and regional television channels to cutting-edge on-demand and high-definition networks. Its national networks include AMC, fuse, IFC (The Independent Film Channel), and WE: Women's Entertainment.

DNF Controls' The Analyst RS422/RS232 Tester saves countless hours of troubleshooting for companies worldwide by helping technicians to eliminate potential sources of a cabling problem. A compact, intuitive device with an easy-to-read, four-line by 40-character LCD screen, an eight-key keyboard, and separate RS422/RS232 connectors, The Analyst doesn't require opening up cables or de-soldering pins, so even non-technical people can use it to achieve results in seconds. It monitors communication between equipment, verifies signal paths, identifies RS422-to-RS232 adapter problems, and is well-suited for use in remote production setups, new studio builds or facility upgrades, and in the maintenance of existing facilities and systems.
