About this Manual
This manual contains information about the Extron FOXBOX 4G
family of ber optic products. The FOXBOX 4G family
(gure 1-1) consists of two compatible sets of ultra-high
performance ber 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 ber
optic cable to the receiver. An optional return (receiver-to-
transmitter) stream of serial RS-232 communications, such as
projector responses, requires a second ber optic cable. Rather
than the return RS-232 communications, the receivers can be
congured to output a daisy-chained primary ber optic signal
to another receiver.
