The FOXBOX 4G Tx/Rx units output continuous
invisible light, which may be harmful and
dangerous to the eyes; use with caution.

Do not look
into the rear panel fiber optic
cable connectors or into the fiber optic cables
themselves.
•
Plug the attached dust caps into the optical
transceivers when the fiber optic cable is
unplugged.
About this Manual
This manual contains information about the Extron FOXBOX 4G
family of fiber optic products. The FOXBOX 4G family
(figure 1-1) consists of two compatible sets of ultra-high
performance fiber optic transmitters and receivers:
•
FOXBOX 4G Tx VGA
transmitter — Accepts an analog
RGB video input, an audio input, and an RS-232 serial
input and outputs a proprietary optical signal to a
FOXBOX 4G or FOX 500 receiver. Also can receive a
proprietary optical signal from the receiver consisting of
the RS-232 return from a controlled device.
•
FOXBOX 4G Rx VGA
receiver — Accepts a proprietary
optical signal from a FOXBOX 4G or FOX 500 transmitter
or daisy-chained receiver and outputs analog RGB video,
audio, and RS-232 serial commands. Also can either:
Receive an RS-232 return from a controlled device
and send it to the transmitter via a proprietary optical
signal.
Output a daisy-chained signal to another receiver.
•
FOXBOX 4G DVI Tx
transmitter — Accepts a single
link of DVI video input, an audio input, and an RS-232
serial input, and outputs a proprietary optical signal to
a FOXBOX 4G or FOX 500 receiver. Also can receive a
proprietary optical signal from the receiver consisting of
the RS-232 return from a controlled device.
•
FOXBOX 4G DVI Rx
receiver — Accepts a proprietary
optical signal from a FOXBOX 4G or FOX 500 transmitter
or daisy-chained receiver, and outputs a single link of DVI
video, audio, and RS-232 serial commands. Also can either:
Receive an RS-232 return from a controlled device
and send it to the transmitter via a proprietary optical
signal.
Output a daisy-chained signal to another receiver.

In this manual, the term "FOXBOX 4G" refers to
either an analog RGB video or a DVI video unit. Where
differences exist between the VGA and DVI models, the
unit's full name is used.
About the FOXBOX 4G Tx/Rx
General system operation
The FOXBOX 4G VGA transmitter inputs VGA - UXGA RGB
video.
The FOXBOX 4G 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. Rather
than the return RS-232 communications, the receivers can be
configured to output a daisy-chained primary fiber optic signal
to another receiver.
