About the FOX 500 Tx/Rx
General system operation
The FOX 500 (RGB) transmitter inputs VGA - UXGA RGB video.
The FOX 500 DVI transmitter inputs a single link of DVI video.
Both transmitters input audio and one-way (transmitter-to-
receiver) RS-232 serial communication (for applications such as
projector control). The transmitters convert all of their inputs
into a proprietary signal, and output the signal on a single
fiber optic cable to the receiver. An optional return (receiver-
to-transmitter) stream of serial RS-232 communications, such
as projector responses, requires a second fiber optic cable. The
transmitter also buffers its video input (either RGB or DVI
as applicable to the model) and loops it through on either a
15-pin HD or DVI connector for use by a local monitor.
The receivers convert the proprietary signal(s) back to video
(either RGB or DVI as applicable to the model), audio, and serial
RS-232 communication, and output the signals locally.
The FOX 500 (RGB) receiver outputs VGA - UXGA RGB video.
The FOX 500 DVI receiver outputs a single link of DVI video.
If RS-232 return communications are implemented (a second
fiber optic cable is installed), the receiver outputs a proprietary
serial communication signal to the transmitter on the second
fiber optic cable. For video resolutions up to 1600 x 1200, the
receiver's video output is a perfect, pixel-for-pixel recreation of
the video signal input to the transmitter.
The transmitter and receiver have image and audio adjustments.
Both units have image, audio, and fiber light status and lost-
light alarm indicators.
The FOX 500 (RGB) transmitter can handle an RGBHV, RGBS,
RGsB, or RsGsBs input signal. The FOX 500 (RGB) receiver can
output RGBHV, RGBS, or RGsB, as selected by the user.
The receivers have built-in alternating pixels, Color Bars,
and grayscale test patterns to assist in setting up the display
equipment.
The FOX 500 transmitters and receivers are rack mountable and
have internal switching power supplies for worldwide power
compatibility.
Cable transmission modes
The transmitters and receivers are further categorized by the
type of fiber optic cable, multimode or singlemode, which define
the effective range of transmission:
• Multimode — Long distance, up to 2 km (6,560')
(depending on the fiber type)

N The multimode and singlemode products are physically
and functionally identical, with the exception of the
effective range of transmission. In this manual, any
reference applies to either transmission mode unless
otherwise specified.
N Many other products are compatible with the Extron
FOX 500 transmitter and receiver. They will be
identified where appropriate, but not specifically
described in this manual.
