Introduction
About this Manual
This manual contains information about the FOX 2G Tx/Rx AV
family of signal transmitters and receivers, with information on
how to mount, install and operate these units.
In this manual, unless otherwise specified, the term
FOX 2G Tx/Rx AV refers to the features or operation of all four
units. The term transmitter refers to both the multi-mode (MM)
and single mode (SM) transmitters and the receiver refers to
both the MM and SM receivers.
About the FOX 2G Tx/Rx AV
The FOX 2G Tx AV and FOX 2G Rx AV are a high performance,
low resolution video, audio, and data (RS-232) transmitter (Tx)
and receiver (Rx) pairs. Signals are transmitted over fiber optic
cable at rates up to 2 Gbps.
There are four different units:
•
•
•
•
FOX 2G Tx AV MM
FOX 2G Tx AV SM
FOX 2G Rx AV MM
FOX 2G Rx AV SM
The MM models have 850 nm multimode small form-factor
pluggable (SFP) modules and carry signals up to 500 m (1640').
The SM models have 1310 nm single mode SFP modules
and carry signals up to 30 km (18 miles). The transmitter is
connected to the receiver using the appropriate fiber optic cable
(SM or MM).
The transmitter and receiver must be compatible. Both
must be MM or both must be SM. It is not possible to
mix types.
N
The FOX 2G Tx/Rx AV outputs continuous
invisible light (Class 1 rated), which may be
harmful and dangerous to the eyes; use with
caution.
W
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.
These low resolution FOX 2G video units are not compatible
with the Extron FOX 500 RGB series, the FOX 500 DVI, the
FOX 500 DA6, or the FOX HD-SDI products. However, they are
compatible with the Extron Fiber Matrix units.
FOX 2G Tx/Rx AV • Introduction
1-2
FOX 2G Tx/Rx AV Features
Digitized signal transmission — Ensures perfect image quality.
The non-linearity of the fiber components does not affect signal
quality. Light can be distributed and repeated without signal
degradation or compression.
Long distance transmission — Signals may be transmitted up to
500 m (1,640 feet) over multi-mode (MM) fiber or up to 30 km
(18 miles) over single mode (SM) fiber.
Daisy chain capability — The system can be expanded to
provide output for up to ten display devices.
Integration friendly — A variety of connectors permits input
and output of composite, S-video, or component video signals.
Compatibility with the Extron Fiber Matrix allows the units to
be integrated into more complex A/V systems.
Transmits multiple signal types — Video, audio and data
signals can all be transmitted simultaneously over one fiber. The
units transmit composite, S-Video, or component video signals
and are compatible with NTSC, PAL, and SECAM standards.
All digital, zero compression technology — The FOX 2G AV
delivers uncompressed pixel-for-pixel transmission of video
signals to ensure optimal image quality.
Auto Input Format Detection — The FOX 2G AV transmitter
can be set to detect the incoming video signal format,
automatically reconfiguring itself to transmit the signal. This
feature can reduce the number of required outputs for a matrix
switcher, lowering system cost while improving manageability.
Encoding and decoding — The FOX 2G Tx AV converts
incoming signals to a proprietary format that is passed along
the fiber optic cable to the FOX 2G Rx AV. At the other end of
the cable, the receiver converts the signal to the low resolution
format that matches the needs of the display device.
Output Video Formatting — The user can set the output video
signal format (composite, S-Video, or component) or follow the
format of the source device (video follow).
Picture and audio adjustments — Available picture adjustments
include color, tint, contrast, and brightness. Audio adjustments
include input gain and attenuation, and output level. Both
audio and video can be muted.
Troubleshooting features — A variety of LED signals and
indicators allow easy diagnosis of problems.
Easy configuration — The units can be configured using
Extron's Special Instruction Set (SIS™) or the FOX Extender
Windows Control Program.

Rack Mounting
UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines are
relevant to the safe installation of the FOX 2G Tx/Rx AV in a
rack:
1.
Elevated operating ambient temperature — If the unit
is installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore,
install the equipment in an environment compatible with
the maximum ambient temperature (Tma: +122 °F, +50 ° C)
specified by Extron.
2.
3.
4.
Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air flow for safe
operation.
Mechanical loading — Mount the equipment in the rack
so that uneven mechanical loading does not create a
hazardous condition.
Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Give appropriate consideration to the
equipment nameplate ratings when addressing this
concern.
5.
Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (such as the use of power
strips).

The length of the exposed wires in the stripping process
is critical. The ideal length is 3/16” (5 mm). Any longer
and the exposed wires may touch, causing a short circuit
between them. Any shorter and the wires can be easily
pulled out even if tightly fastened by the captive screws.

Video Connections
The FOX 2G Tx/Rx AV accepts a single low resolution video
signal (composite, S-video and low resolution component video)
and outputs a single low resolution video signal (composite,
S-video and low resolution component video). It is not
compatible with RGB or HDTV 480p, 720p, or 1080i component
video signals.
The transmitter converts incoming signals to a proprietary
format and passes them along the fiber optic cable to the FOX
2G Rx AV. The receiver converts the signal to a format that
matches the display requirements. SIS™ commands are used to
configure the receiver to convert between signal formats (see
page 3-10).
To input a low resolution component signal,
Y/VID
B-Y/C
or output a component output signal, connect
three BNC male connectors to the Y/VID,
B-Y/C, and R-Y receptacles on the back panel of
the unit.

Component
There are two alternative methods to input or
output an S-video signal:
Y/VID
B-Y/C
• Connect BNC male connectors to the
Y/VID and B-Y/C receptacles on the back
panel of the unit.
• Connect a 4-pin mini DIN to the S-VID
receptacle on the back panel of the unit.

In addition to the selected output type,
using BNC connectors, a transcoded
S-video signal is always output from
the receiver's S-VID socket.

Audio Connections
Audio input to the FOX 2G Tx AV and audio output from the
FOX 2G Rx AV are made through the 3.5 mm, 5-pole, captive
screw connectors. Input and output can be mono or stereo
and can be balanced or unbalanced, depending on the wiring
connections (see figure below).
Do not tin the wires!

The Audio LED lights up immediately when the
transmitter detects an audio signal 35 dB below the
nominal level. It remains lit until the audio signal drops
below that threshold continuously for 10 seconds.

ALARM
Alarm
The alarm pins, labeled 1 and 2, (see figure at right)
on the rear panel of the FOX 2G Tx/Rx AV act
as a short when activated. They do not produce
any discrete on/off voltage signals but, instead,
act as an internal relay that will either connect or
disconnect an external alarm circuit.

2
For the FOX 2G Tx AV, the alarm state is activated
when link 2 is absent. For the FOX 2G Rx AV, the
alarm state is activated when link 1 is absent.
When power is lost, both the alarm state is
activated for both units.

Fiber Optic Cable Connector
OPTICAL
Tx
Rx
The transmitter and receiver units of the
FOX 2G Tx/Rx AV are connected by an LC duplex
SFP connector. Fiber optic link 1 connects the Tx port
of the transmitter and the Rx port of the receiver. It
carries video, audio and/or data output from the
transmitter to the receiver.
Fiber optic link 2 connects the Tx port of the receiver
with the Rx port of the transmitter. It only carries the
responses to RS-232 commands and is not required for
transmitting video and audio signals.
However, if link 2 is not enabled, the ability to
configure the system through SIS commands is limited
by the lack of communication from the receiver to
the transmitter. All commands issued through the
transmitter are valid but responses to status queries
may return invalid data.
OPTICAL
Tx
Rx
Signals may be transmitted 500 m (1,640 feet) over multi-mode
(MM) fiber and 30 km (18 miles) over single mode fiber. An MM
transmitter must always be connected to a MM receiver and an
SM transmitter can only be connected to a SM receiver.
The FOX 2G Tx/Rx AV outputs continuous
invisible light (Class 1 rated), which may be
harmful and dangerous to the eyes; use with
caution.
W
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.
An LED above each port lights when a signal is received. The
receiver unit's optical Rx port will light when a signal from fiber
link 1 reaches the receiver. The transmitter unit's optical Rx port
will light when a signal from link 2 reaches the transmitter.
