Introduction
This user guide contains information about the Extron FOX Tx/Rx AV family of signal transmitters and receivers, with information on how to install and operate these units.
In this guide, unless otherwise specified, the terms "FOX Tx/Rx AV" and "FOX AV" refer to the features or operation of all four units. The terms "FOX Tx AV" and "transmitter" refer to both the multimode (MM) and singlemode (SM) transmitters and "FOX Rx AV" or "receiver" refer to both the MM and SM receivers.
About the FOX Tx/Rx AV
The FOX Tx AV and FOX 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 Tx AV MM (multimode transmitter)
• FOX Tx AV SM (singlemode transmitter)
• FOX Rx AV MM (multimode receiver)
• FOX Rx AV SM (singlemode receiver)
The MM models have 850 nm multimode small form-factor pluggable (SFP) modules and carry signals up to 2 km (6562 feet). The SM models have 1310 nm singlemode SFP modules and carry signals up to 30 km (18.6 miles). The transmitter is connected to the receiver using the appropriate fiber optic cable (SM or MM).
WARNING:
AVERTISSEMENT :
- The transmitter and receiver must be compatible. Both must be MM or both must be SM. It is not possible to mix types.
- Plug the attached dust caps into the optical transceivers when the fiber optic cable is unplugged.
The FOX Tx/Rx AV video units are compatible with the Extron Fiber Matrix units. However, they are not compatible with the following Extron products:
FOXBOX
• FOX 500 (RGB) and FOX 500 DVI
FOX 3G HD-SDI
FOX II
- PowerCage 1600
- Power Cage 401
FOX 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.
- All digital, zero compression technology — delivers uncompressed pixel-for-pixel transmission of video signals to ensure optimal image quality.
- Transmits multiple signal types — transmits video, audio and data signals simultaneously over one fiber. The units transmit composite, S-Video, or component video signals and are compatible with NTSC, PAL, and SECAM standards.
- Auto Input Format Detection — the FOX 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 Tx AV converts incoming signals to a proprietary format that is passed along the fiber optic cable to the FOX 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.
- Daisy chain capability — the system can be expanded to provide output for up to ten display devices.
- Long distance transmission — signals may be transmitted up to 2 km (6562 feet) over multimode fiber or up to 30 km (18.6 miles) over singlemode fiber.
- Integration friendly — a variety of connectors permits input and output of composite, S-video, or component video signals. Compatibility with Extron Fiber Matrix products allows these units to be integrated into more complex AV systems.
- Troubleshooting features — LED signals and indicators allow easy diagnosis of problems.
- Easy configuration — the units can be configured using the Extron Special Instruction Set (SIS) or the FOX Extender Control Program.

Power supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply, the transmitter, the receiver, or all three. Identify the ground wire by the ridges on the side of the cord (see figure 4).
- Connect the AC power cord of the power supply unit to a 110 or 220 VAC electrical source.
- When the transmitter or receiver is getting power, the front panel LED shows an amber light.
ATTENTION:
B Video connections (see figure 3 on page 5) — Three BNC connectors and one 4-pin mini DIN S-video connector for video input and output.
The FOX 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 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 Command and Response Table for SIS Commands on page 16).
Component Signal
To input a low resolution component signal, 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 as shown in the figure at right.

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

Y/VID B-Y/C Y/VID B-Y/C R-Y S-VID R-Y S-VID S-video S-videoNOTE: When a signal is output using BNC connectors, an additional transcoded S-video signal is always output from the S-VID socket of the receiver.
Composite Signal
To input or output a composite signal, use a single BNC male connector to the Y/VID receptacle on the back panel of the unit.

Comp
When both the BNC connectors and the 4-pin mini DIN provide simultaneous video input, the signal with the highest priority for video output is shown, highlighted in blue, in the table below:
| BNC Input Mini | DIN Input |

| S-Video S-Video | |
| Composite S-Video |
Audio connections (see figure 3 on page 5) — A 3.5 mm, 5-pole captive screw connector for audio input and output (see the figure at right). Input and output can be mono or stereo and can be balanced or unbalanced, depending on the wiring connections (see figure 5).

See the Attention on page 6 for important information about preparing and connecting wires to captive screw connectors.
The table below shows the initial gain differences between audio input/output connectors, using captive screw connectors. The unbalanced output from the captive screw connector is half (-6 dB), regardless of input.
| Input Output Gain | |
| Balanced Balanced 0 dB (unity) | |
| Balanced Unbalanced -6 dB (half) | |
| Unbalanced Balanced 0 dB | |
| Unbalanced Unbalanced -6 dB |
Additional adjustment of audio gain or attenuation can be made using SIS Commands (see page 14).
NOTE: 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.
RS-232 connections (see figure 3) — The Remote RS-232 connections (see the figure at right) allow the transmitter and receiver units to be configured using SIS Commands (see page 14) or the FOX Extender Control Program (see page 20).

The Over Fiber RS-232 connections (see the figure at right) allow pass-through to remote units.

For more information see RS-232 Ports on page 11.
NOTE: Over fiber RS-232 communications are via a passive pass-through only; the FOX Tx/Rx AV units neither generate nor respond to these signals.
E Alarm (see figure 3 on page 5) — When connected to an alarm, this 3.5 mm 2-pole captive screw connector gives a warning when light signals have been disconnected, lost, or broken.
See the Attention on page 6 for important information about preparing and connecting wires to captive screw connectors.
The alarm pins, labeled 1 and 2, (see the figure at right) on the rear panel of the FOX Tx/Rx AV act as a short when activated. They do not produce any discrete on or off voltage signals but act as an internal relays that either connect or disconnect external alarm circuits.
For the FOX Tx AV, the alarm state is activated when link 2 is absent. For the FOX Rx AV, the alarm state is activated when link 1 is absent.
When power is lost, the alarm state is activated for both units.
Fiber optic cable connector (see figure 3) — An LC duplex SFP connector links the transmitter and receiver. An LED above each port lights when a signal is received. The optical Rx port of the receiver lights when a signal from fiber link 1 reaches the receiver. The optical Rx port or the transmitter lights when a signal from link 2 reaches the transmitter.
WARNING:
AVERTISSEMENT :
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.
Link 2 is optional. It 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.
Signals may be transmitted 2 km (6561 feet) over multimode (MM) fiber and 30 km (18 miles) over singlemode fiber. An MM transmitter must always be connected to a MM receiver and an SM transmitter can only be connected to a SM receiver.
Daisy Chain Capability
FOX Rx AV receivers have a loop-out mode that allows a signal to be passed 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 (see SIS Commands on page 14).
All receivers in the daisy chain must be compatible, that is 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.
NOTES:
- In daisy chain mode, the Tx port passes 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 system configuration with SIS commands is limited.
- When multiple receivers are in daisy chain mode, RS-232 commands issued through the transmitter pass to every receiver but commands issued through a receiver apply only to that receiver. Configuring each receiver independently, matches each output signal to the unique needs of the display device.

This section of the user guide provides information about:
- RS-232 Ports
• RS-232 Control of Tx and Rx Units - SIS Commands
• Command and Response Table for SIS Commands
• FOX Extender Control Program
RS-232 Ports
Both the FOX Tx AV and FOX Rx AV have a front panel TRS port and a rear panel captive screw port, which can provide SIS commands to configure the transmitter/receiver settings when connected to a control device (see Command and Response Table for SIS Commands on page 16).
NOTE: 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.
The protocol for both ports is 9600 baud, no parity, 8 data bits, 1 stop bit, and no flow control.
NOTE: Both RS-232 Remote and RS-232 Over Fiber signals require fiber optic link 1 and link 2 for full functionality (see RS-232 Control of Tx and Rx Units on page 13).
The front panel Config port uses a 2.5 mm mini jack connector. Extron recommends the 9-pin D Female to 2.5 mm TRS Configuration Cable (see www.extron.com).

NOTE: Control signal ground pins for Extron products may be labeled as 12 or G. The wiring and function are the same, whichever way your product is labeled.
As an alternative to the front panel TRS port, the RS-232 Remote port, on the rear panel, uses three connectors in a 5-pole captive screw connector.

In addition, on the rear panel, the units have RS-232 Over Fiber pass-through ports. These ports allow RS-232 commands to be passed from the control device to remote devices over the fiber optic cable with speeds up to 115 kbps.
NOTE: The FOX Tx/Rx AV does not respond to, or generate a response to, any commands passed through the "RS-232 Over Fiber" ports. Refer to the user guide of the device being controlled for the appropriate SIS commands.

RS-232 Control of Tx and Rx Units
When the FOX 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:

C["Process Input configuration Audio gain"] --> A
D["Process Color Tint Brightness Contrast Video mute Output configuration Daisy chain/ loop out mode Audio mute Audio output level"] --> B
Figure 10. 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 is processed normally because only fiber link 1 is required.
Queries from the transmitter about the status of receiver settings are not 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, within four seconds of link 2 becoming active, the receiver settings are automatically copied to the transmitter to ensure settings for both units match.
NOTE: When the receiver settings are copied to the transmitter, existing transmitter settings are overwritten and it may be necessary to update those values.
SIS Commands
Introduction to SIS
SIS commands consist of a string (one or more characters per command field). 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 Tx/Rx AV unit is first switched on, depending on the model, it sends one of the following messages:
(c) Copyright 2008, Extron Electronics, FOX 2G Tx AV, Vx.xx, 60-941-11← or
(c) Copyright 2008, Extron Electronics, FOX 2G Tx AV, Vx.xx, 60-941-12← or
(c) Copyright 2008, Extron Electronics, FOX 2G Rx AV, Vx.xx, 60-941-21← or
(c) Copyright 2008, Extron Electronics, FOX 2G Rx AV, Vx.xx, 60-941-22
where V x.xx is the firmware version number and 60-941-xx is the catalog number.
Symbols Used in This Guide
When programming in the field, certain characters are most conveniently represented by the hexadecimal equivalent of their ASCII value. For convenience, the table below shows the hexadecimal equivalent of each ASCII command:

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 return invalid data.
All configuration of the receiver by commands issued through the receiver is valid. Attempts to configure the the transmitter through the receiver in the absence of link 2 are invalid.
The following table shows the validity of commands issued through the receiver when only link 1 is active:
| Adjustment | |
| Color Valid | |
| Tint Valid | |
| Brightness Valid | |
| Contrast Valid | |
| Audio gain/attenuation | Invalid |
| Audio mute Valid | |
| Audio output level Valid | |
| Output configuration Valid | |
| Input configuration | Invalid |
| Daisy chain mode Valid | |
| Test pattern Valid | |
| Video mute Valid |
FOX Extender Control Program
The Extron FOX Extender Control Program 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 control program can be downloaded from the Extron Website (www.extron.com).

NOTE: 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.
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 more than 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.
NOTE: If the computer is connected to either of the transmitter control ports and link 2 is disconnected, the link 1 indicator does not show green because, when the receiver detects light on link 1, it is not able to pass that information to the transmitter.
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 type (the transmitter or receiver) and model description for the unit 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 and the internal temperature.
Memory Preset area
The Memory Preset area provides tools to save and recall memory presets:

Video Adjustment Color 64 Tint 64 Contrast 64 Brightness 64Video Format area
Click the radio buttons in the video format areas to select the input format (Auto, Component, S-video, or Composite) and output format (Follow input type, Component, S-video, or Composite).
NOTE: The transmitter converts the input signal into a 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 there are two video sources, S-video through the 4-pin mini DIN and another format through the BNC connectors, the choice of button determines which input format is transmitted. When Auto is selected, the transmitter automatically detects the input format.
When follow input type is selected for the output format, the output signal is in the same format as the original input signal.

Link 2/Daisy Chain Mode — provides radio buttons to choose the mode for the Tx port of the receiver. 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 are 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.

Audio Gain/Attenuation — provides a click and drag slider control to select the input audio gain or attenuation value, from -18 dB to +10 dB in 1.0 dB increments.
NOTE: The transmitter converts the input signal into a 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.
Audio Output Level — provides radio buttons to allow a choice between consumer level (-10 dBV) or professional level (+4 dBu) for the audio output.
Firmware for FOX Tx/Rx AV
Firmware can be downloaded onto the unit from the Extron website (www.extron.com).
The transmitter and receiver require different firmware and must both be upgraded separately.

Underwriters Laboratories Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:
- 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, +45 °C) specified by Extron.
- 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.
- 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).
