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 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).

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

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.

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.

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.
The length of the exposed wires in the

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.

Daisy Chain Capability
FOX 2G Rx AV receivers have a loop-out mode that allows a
signal to be passed from the receiver along a daisy chain of
to up to ten receivers, with a display device attached to each
receiver. The loop-out mode is set using RS-232 commands. For
more information, see chapter 3, "Simple Instruction Set (SIS)
Commands".
All receivers in the daisy chain must be compatible, i.e. they
must all be SM or all be MM models, connected with the
appropriate fiber optic cable. Each receiver receives a signal
at its Rx fiber optic port and passes the signal to the next unit
through its Tx port.
In daisy chain mode, the Tx port is used to pass audio
and video signals to the next receiver in the daisy chain.
As a result, the Tx port is not available for bidirectional
communication and there are limitations on system
configuration with SIS commands.
N
When multiple receivers are in daisy chain mode,
RS-232 commands issued through the transmitter will
be passed to every receiver but commands issued through
a receiver will apply only to that receiver. Configuring
each receiver independently, matches each output signal
to the unique needs of the display device.

Configuration
RS-232 Ports
Both the FOX 2G Tx AV and FOX 2G Rx AV have a front panel
TRS port and a rear panel captive screw port, which can provide
SIS commands to configure the tranmitter/receiver settings
when connected to a control device.
SIS commands for the FOX 2G Tx/Rx AV are shown (starting on
page 3-8).
The two comm ports work in parallel. However,
depending on the computer or the communication
settings, connecting to both comm ports at once may
result in one or both ports not working. Extron
recommends that only one comm port (front or back) is
used at a time.
N
The protocol for both ports is 9600 baud, no parity, 8 data bits,
1 stop bit, and no flow control.
Both RS-232 Remote and RS-232 Over Fiber signals
require fiber optic link 1 and link 2 for full functionality
(see page 3-4).
N
The front panel Config port uses a 2.5 mm mini jack connector.

RS-232 Control of Tx and Rx Units
When the FOX 2G Tx/Rx AV is configured by RS-232
commands, some commands are processed by the transmitter
and others are processed by the receiver. The SIS commands do
not distinguish between the two units. The system routes the
commands based on where they are processed.
A system block diagram showing which functions are processed
by the transmitter and which are processed by the receiver is
shown below:

Figure 3-4 — System block diagram
For full functionality, both fiber optic links must be enabled.
If only Link 1 is enabled, the ability to configure the system
through SIS commands is limited by the lack of return
communication from the receiver to the transmitter:
• All configuration carried out using the transmitter will be
processed normally because only fiber Link 1 is required.
• Queries from the transmitter about the status of receiver
settings will not be processed correctly because fiber Link 2 is
required to carry the return signal.
• The receiver cannot be used to configure the transmitter
because fiber Link 2 is required.
The lack of communication between the transmitter and the
receiver can result in mismatches in the value settings of the
two units, which may cause confusion with control systems
or software applications. To avoid this confusion, within four
seconds of Link 2 becoming active, the receiver settings are
automatically copied to the transmitter to ensure settings for
both units match.
When the receiver settings are copied to the transmitter,
existing transmitter settings are overwritten and it may
be necessary to update those values.

Simple Instruction Set (SIS™) Commands
Introduction to SIS
SIS commands consist of a string (one or more characters per
command field). For the FOX 2G Tx/Rx AV, apart from setting
audio gain ("G") and attenuation ("g"), upper and lower case
characters may be used interchangeably. Commands do not
require any special characters to begin or end the command
string. Each response from the unit ends with a carriage return
]
and a line feed (CR/LF = ), which signals the end of the
response character string.
When the FOX 2G Tx/Rx AV unit is first switched on,
depending on the model, it sends one of the following messages:
© Copyright 2008, Extron Electronics, FOX 2G Tx AV, Vx.xx,
]
60-941-11

Windows®-Based Program Control
The Extron FOX Extender Windows Control Program (WCP)
communicates with the transmitter and receiver pair via the rear
panel Remote RS-232 port or front panel Configuration port of
either unit.
The program is compatible with Windows 2000, Windows XP
and later versions of Windows. Upgrades to the program can be
downloaded from the Extron Web site (www.extron.com).
Installing the software
The control program is on the CD-ROM that is provided with
the transmitter and/or receiver. To install the program, insert
the CD-ROM into the computer's drive. If the setup program
does not start automatically, run Launch.exe from the CD and
follow the instructions that appear on the screen.
By default, the Installer program will create a C:\Program Files\
Extron\Fox Extenders folder, containing the FOX Extender
Windows control program. An icon may also be placed on the
Windows desktop.
Starting the program
Start the Extron FOX Extender WCP as follows:
1. Set up and power on the units as described in Chapter 2.
Connect the PC to one of the control ports on either the
transmitter or receiver.
2. Click Start > All Programs > Extron Electronics >
FOX Extender WCP > FOX Extender WCP or click on
the desktop icon (see icon at right).
The Communication Setup window opens (see figure 3-5):
Figure 3-5 — Communication Setup window

Configuration, cont’d
3. Select the Com port to which your transmitter or receiver is
connected and click Connect.
The Communication Setup window closes and the FOX
Extender WCP window comes into focus (see figure 3-6).
Figure 3-6 — FOX Extender WCP window
Only Link 1, connecting the Tx port of the transmitter
to the Rx port of the receiver, is required for video, audio,
and serial command transmission. Link 2 is not required
but, if it is not enabled, the ability to configure the
system is limited by a lack of communication from the
receiver to the transmitter.
N
Status area
The Status area provides visual indications of the connection
status:
Figure 3-7 — Status area
•
Video present indicator — Shows green to indicate the
presence of Composite, S-Video, or Component video
signals.
•
Audio present indicator — Shows green when the
transmitter detects an audio signal at or above 35 dB below
the nominal level. Stays on until the signal falls below this
threshold continuously for 10 seconds.

•
Loop-out indicator — Only visible if the computer is
connected to the receiver.
Link 1 indicator — Shows green when the receiver detects
light on Link 1 (connecting the Tx port of the transmitter to
the Rx port of the receiver). The receiver reports the status
to the transmitter over Link 2.
If the computer is connected to either of the transmitter's
control ports and Link 2 is disconnected, the Link 1
indicator will not show green because, when the receiver
detects light on Link 1, it will not be able to pass that
information to the transmitter.
N
•
Link 2 (Optional) indicator — Shows green when the
transmitter detects light on Link 2 (connecting the Tx
port of the receiver to the Rx port of the transmitter). The
transmitter reports the status to the receiver via Link 1.
The status area also shows the unit (the transmitter or receiver)
to which the computer is connected, the unit at the other end of
the fiber optic cable and the COM port on the computer that is
connected to the unit.
It also provides information about the horizontal and vertical
frequencies of the input signal.
Memory Preset area
The Memory Preset area provides tools to save and recall
memory presets:
Figure 3-8 — Memory Preset area
Memory Presets save the values of color, tint, contrast, and
brightness.
Mute area
The Mute area provides radio buttons that allow the video and/
or audio to be muted.

The Video Adjustment area allows adjustments to the color, tint,
contrast, and brightness of the picture that is displayed.

Video Format areas
The Video Format areas (Input Video Format and Output Video
Format) provide radio buttons that allow the input format (auto,
component, S-video, or composite) and output format (follow
input type, component, S-video, or composite) to be selected.
Figure 3-11 — Video Format area
The transmitter converts the input signal into a
N
proprietary signal type, which passes through Link 1 to
the receiver. The receiver converts the signal back to the
required signal type. This allows the input signal to be
transcoded to meet the requirements of the output device.
When Auto is selected for the input format, the transmitter will
automatically detect the signal type. When follow input type is
selected for the output format, the output signal will be in the
same format as the original input signal.

Link 2/Daisy Chain Mode — Provides radio buttons to choose
the mode for the receiver's Tx port. If it is connected to the
transmitter, the link may be enabled or disabled. Alternatively,
the port may be connected to another receiver with the Daisy
Chain mode enabled.
Auto Memory — May be switched on or off, using radio
buttons. When Auto Memory is on, previously saved values
such as color, tint, contrast, and brightness will be applied
whenever the vertical field rate of the input changes.
Auto Image — Returns the video adjustment settings of color,
tint, contrast, and brightness back to their default values (64).
Test Patterns — Allow the user to select one of three built-in test
patterns (color bars, grayscale, or alternating pixels), which help
calibrate the display device. When Off is selected, the receiver
outputs the video signal from the source device.

Changes to the input gain or attenuation are made in
the transmitter. If the control computer is connected
to the receiver and Link 2 is not active, the gain and
attenuation values cannot be changed.

Firmware for FOX 2G Tx/Rx AV
Firmware can be downloaded onto the unit from the Extron Web
site (www.extron.com). The transmitter and receiver require
different firmware and must both be upgraded separately.
SIS Command Validity Table
If only one fiber optic channel is enabled, the ability to configure
the system through SIS commands is limited by the lack of
return communication from the receiver to the transmitter.
All commands issued through the transmitter are valid because
link 1 allows signals to be forwarded to the receiver. However,
responses to queries originating from the transmitter about the
status of the receiver will return invalid data.
All configuration of the receiver by commands issued through
the receiver will be valid. Attempts to configure the the
transmitter through the receiver in the absence of link 2 will be
invalid.
The following table shows the validity of commands issued
through the receiver when only link 1 is active:
