General System Operation
The PowerCage FOX VGA transmitter inputs VGA-UXGA RGB video.
The PowerCage FOX DVI Plus 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
the inputs to them 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. Rather
than the return RS-232 communications, the receivers can be configured to output a daisy-
chained primary fiber optic signal to another receiver.
The PowerCage FOX VGA receiver outputs VGA-UXGA RGB video.
The PowerCage FOX DVI receiver outputs a single link of DVI video.
The receivers convert the proprietary signal back to video (either RGB or DVI as applicable to
the model), audio, and serial RS-232 communication and output the signals locally. If either
RS-232 return or daisy-chained communications are implemented (a second fiber optic cable
is installed), the receiver outputs a proprietary signal on the second fiber optic cable. For
video resolutions up to 1600 x 1200 or 1080p, the video output of the receiver is a perfect,
pixel-for-pixel recreation of the video signal input to the transmitter.
The PowerCage FOX VGA transmitter can handle an RGBHV, RGBS, RGsB, or RsGsBs input
signal. The PowerCage FOX VGA receiver can output RGBHV or RGsB, as selected by the
user.
The transmitter and receiver have image and audio adjustments available under RS-232
control. Both units have fiber light status indicators and lost-light alarm connectors.
The receivers have built-in alternating pixels, Color Bars, and grayscale test patterns to assist
in setting up the display equipment.
