The Extron FOX RS 104 is a four port fiber optic RS-232 inserter for long-haul transmission of control signals to remote devices over fiber optic cabling. Each port provides a bidirectional fiber optic connection to a FOX Series extender for the insertion and extraction of control data, while maintaining a continuous pass-through link for video and audio. Engineered for reliability and exceptional high resolution image performance, it uses Extron all-digital technology to deliver pixel-perfect HDMI, DVI, computer-video, and standard definition video. Output reclocking on the buffered fiber optic outputs ensures signal integrity, sending a fiber optic signal at its original power level.
