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.
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 — The FOX AV delivers uncompressed pixel‑for‑pixel transmission of video signals to ensure optimal image quality. Transmits multiple signal types — Video, audio and data signals can all be transmitted simultaneously over one fiber.
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 (see Operating distance Specs on page 24) or up to 30 km (18.6 miles) over singlemode fiber.

FOX Tx AV Rear Panel Features f Power input — This 3.5 mm, 2-pole captive screw connector accepts 12 VDC from an external power supply (provided).
CAUTION: Always use a power supply supplied by or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product. Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities.
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. Y/VID B-Y/C R-Y S-VID Composite 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 highlighted in blue in the table below: h BNC Input Mini DIN Input Component S-Video S-Video S-Video Composite S-Video Audio connections — A 3.
RS-232 connections — The Remote RS-232 connections (see the figure at right) allow the transmitter and receiver units to be configured using SIS commands (see page ) or the FOX Extender Control Program (see page 13). The Over Fiber RS-232 connections (see the figure at right) allow pass‑through to remote units. RS-232 OVER FIBER REMOTE Tx Rx OVER FIBER REMOTE For more information see RS-232 Ports on page 12.
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 13). 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.
Configuration This section of the user guide provides information about: zz RS-232 Ports zz RS-232 Control of Tx and Rx Units zz SIS Commands zz 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. SIS commands for the FOX Tx/Rx AV start on page 13. NOTE: The two comm ports work in parallel.
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.

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.
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.
X@ — Color, tint, contrast, or brightness adjustment (0 to 127) X# — Auto Memory, blanking, or audio mute status 0 = disabled 1 = enabled X$ — Output video type 0 = Follow input type 6 = Component 7 = S-video 8 = Composite X% — Audio gain (0 to +10 dB) X^ — Audio attenuation (-18 to 0 dB) X& — Audio level (-18 to +10 dB) X* — Audio output level 0 = Consumer level (-10 dBV) (default) 1 = Professional level (+4 dBu) X( — Test pattern 0 = Test pattern off 1 = Color bars 2 = Grayscale 3 = Alternating pixels

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.
Starting the Program Start the Extron FOX Extender control program as follows: 1. Set up and power on the units as described in Power Input on page 5. Connect the PC to one of the control ports on either the transmitter or receiver (see page 10). 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: Figure 12. Communication Setup Window 3.
Status area The Status area provides visual indications of the connection status: Figure 14. Status Area 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.
Memory Preset area The Memory Preset area provides tools to save and recall memory presets: Figure 15. Memory Preset Area Select a Preset Number from the dropdown menu and click Save. The current values of color, tint, contrast, and brightness are saved as a Memory Preset. Previously saved memory presets can be called by selecting a Saved Number from the dropdown menu and clicking on Recall. Mute area Select either the On or Off radio buttons in the Mute area to mute or unmute the video and audio signals.
Advanced Configuration area 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.
Specifications NOTES: The FOX AV consists of a transmitter (FOX Tx AV) and a receiver (FOX Rx AV) with one or two fiber optic cables linking the two units. The analog video input signal is digitized pixel for pixel in the transmitter, sent digitally through the fiber cable, and converted back to analog video in the receiver. The analog audio signal(s) is (are) digitized in the transmitter, sent through the fiber cable, and converted back to analog audio in the receiver.
