System Compatibility
The PowerCage FOX Tx/Rx AV video units are compatible with the FOX Tx/Rx AV fiber
optic video transmitter and receiver and with the FOX Series distribution amplifiers,
switchers, and matrix switchers. However, they are not compatible with the following
Extron products:
z FOXBOX
z FOX 500 (RGB) and FOX 500 DVI
z FOX 500 DA6
z FOX 3G HD-SDI
z PowerCage FOX 3G HD-SDI Series
z PowerCage FOX VGA and DVI
Cable Transmission Modes
The transmitters and receivers are further categorized by the type of fiber optic cable,
multimode or singlemode, which defines the effective range of transmission:
z
Multimode — Long distance: up to 2 km (6,561 feet) (depending on the fiber cable)
z
PowerCage FOX Tx AV MM
z
PowerCage FOX Rx AV MM
z
Singlemode — Very long distance: up to 30 km (18.75 miles)
z
PowerCage FOX Tx AV SM
z
PowerCage FOX Rx AV SM
NOTE: The multimode and singlemode products are physically and functionally
identical, except for the effective range of transmission. In this guide, any
reference applies to either transmission mode unless otherwise specified.
General System Operation
The PowerCage FOX Tx/Rx AV transmitter accepts a single low resolution video signal
(composite, S-video, or low resolution component video). It accepts audio and one-way
(transmitter-to-receiver) RS-232 serial communication (for applications such as projector
control). The transmitter converts all of its incoming signals into a proprietary format
signal, which it outputs on a single fiber optic cable to the PowerCage FOX Rx AV
receiver. An optional return (receiver-to-transmitter) stream of serial RS-232
communications, such as projector responses, requires a second fiber optic cable. Instead
of the return RS-232 communications, the receiver can be configured to output a
daisy-chained primary fiber optic signal to another receiver.
The PowerCage FOX Tx/Rx AV receiver outputs a single low resolution video signal
(composite, S-video or low resolution component video), which is not compatible with
RGB or HDTV 480p, 720p, or 1080i component video signals. The receiver converts the
proprietary signal back to video, audio, and serial RS-232 communication (matching the
display requirements) and outputs the signals locally. The Extron Simple Instruction Set
(SIS ™ ) commands are used to configure the receiver to convert between signal formats. 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 cable.
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.
