About this Guide

This guide contains information about the ultra-high performance Extron
FOXBOX Tx/Rx HDMI fiber optic transmitters and receivers (see figure 1 on the next page).

About the FOXBOX Tx/Rx HDMI

The FOXBOX HDMI Fiber Optic Extender is an ultra-high performance fiber optic transmitter
and receiver set for long haul transmission of HDCP-compliant HDMI video, audio, and
RS-232 control signals over fiber optic cabling. The transmitter and receiver can extend
HDMI signals up to 30 km (18 miles).

NOTE: For HDCP compliance:

• A FOXBOX HDMI or PowerCage FOX HDMI transmitter must be paired with a

FOXBOX HDMI or PowerCage FOX HDMI receiver.

• You must connect both fiber optic cables between the transmitter and receiver.

• A signal cannot be daisy-chained and retain HDCP compliance.

• The bidirectional Consumer Electronics Control (CEC) is not supported.

Figure 1. Typical FOXBOX Tx/Rx HDMI Application

The FOXBOX Tx HDMI transmitter accepts HDMI video or DVI-D video (with an applicable
adapter), at resolutions up to 1920 x 1200 at 60 Hz. The video input can also include
embedded audio. The transmitter also loops the HDMI input through for a local monitor.

The transmitter can also accept an analog audio input on 3.5 mm mini jack. A front panel
DIP switch selects either the embedded audio or the separate analog audio for the unit to
transmit to the receiver.

The transmitter accepts a one-way (transmitter-to-receiver) RS-232 serial communication
(for applications such as projector control) serial signal input. The transmitter can receive an
optional return (receiver-to-transmitter) stream of serial RS-232 communications, such as
projector responses.

The transmitter converts the HDMI video, the selected audio, and the RS-232 serial
communication into a proprietary data stream and outputs it as an optical signal on a single
LC connector to a compatible fiber optic receiver. It also can receive a proprietary optical
signal from the receiver consisting of the RS-232 return from a controlled device.

FOXBOX Tx/Rx HDMI • Introduction 2

Receiver

Both Units

The FOXBOX Rx HDMI receiver accepts a proprietary optical signal on a single LC
connector from a compatible fiber optic transmitter or daisy-chained receiver.

The receiver outputs a single link of HDMI video, digital audio (embedded in the HDMI
output), analog audio, and RS-232 serial commands.

If the receiver is appropriately configured and has a second fiber optic cable installed, it 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.

If either RS-232 return or daisy-chained communications are implemented, the receiver
outputs a proprietary signal on the second fiber optic cable carrying the signal.

For video resolutions up to 1600 x 1200, 1080p, or 1920 x 1200, the video output of the
receiver is a perfect, pixel-for-pixel recreation of the video signal input to the transmitter.

With the appropriate adapter, the single link of HDMI video output by FOXBOX Rx HDMI can
be converted to DVI-D video.

The receiver has built-in alternating pixels, color bars, and grayscale test patterns to assist in
setting up the display equipment.

The transmitter and receiver have many controls, including image and audio adjustments,
that are available under RS-232 Simple Instruction Set (SIS™) control. Both units have
image, audio, fiber light status, and lost-light alarm indicators.

System Compatibility

The FOXBOX Tx HDMI transmitter operates in either of two modes, selected under
RS-232 control, for compatibility with other, non-HDMI, units:

• Plus — Support resolutions up to 1920 x 1200 @ 60 Hz. The fiber optic output of

the transmitter can be received only by one of four receivers: a FOXBOX HDMI Rx, a
FOXBOX DVI Plus Rx, a PowerCage HDMI Rx, or a PowerCage FOX DVI Plus Rx.

• Non-Plus — Supports resolutions up to 1600 x 1200 @ 60 Hz. The fiber optic

output of the transmitter can be received by any FOXBOX, PowerCage FOX, and
FOX 500 VGA and DVI unit, including the Plus and non-Plus units.

The FOXBOX Rx HDMI receiver operates interchangeably with all FOXBOX, PowerCage
FOX, and FOX 500 VGA and DVI units, including Plus and non-Plus units.

NOTES:

• Although the receiver can operate with non-HDMI transmitters, the video output is

not HDCP-compliant.

• The transmitter and receiver are not compatible with the FOX AV,

PowerCage FOX AV, FOX 3G HD-SDI, PowerCage FOX 3G HD-SDI, and
FOX 3G DVC models.

FOXBOX Tx/Rx HDMI • Introduction 3

Features

• Ultra high performance — Offers pixel-for-pixel HDMI or DVI-D (with an adapter)

video transmission, up to 1920 x 1200 at 60 Hz (in Plus mode) or 1600 x 1200 at 60 Hz
(in non-plus mode).

• Video input — The transmitter accepts a single link of HDMI or DVI-D video.

• Loop-through on transmitter — The transmitter has an HDMI loop-through on a

HDMI connector that allows connection of a local monitor.

• EDID emulation mode (Display Data Channel [DDC]) — The FOXBOX Tx HDMI

transmitter provides a selector switch for specifying the rate of the incoming digital video
signal. EDID emulation mode allows proper operation when no local monitor is present.

• Video output — The receiver outputs a single link of HDMI video.

• Extron fiber optic product compatibility — Enables ultra-long distance

HDMI-to-analog RGB and analog RGB-to-HDMI conversion without the need for extra
signal conversion devices.

• Compatibility with FOX 500 DA6 distribution amplifier and FOX Matrix Switchers

• Analog audio input — The transmitters accept an unbalanced stereo or mono audio

input on a 3.5 mm mini jack.

• Analog audio input gain/attenuation — The input audio level of the analog audio can

be adjusted within a range of -18 dB (attenuation) to +10 dB (gain) via the RS-232 link.

• Analog audio output — The receiver outputs balanced or unbalanced stereo audio on

a 5-pole captive screw connector and digital audio embedded in the HDMI output.

• Links monitoring — The panels of the transmitter and receiver have indicators for

monitoring image and audio transmission and both fiber optic links.

• Loss-of-light alarms — The panels of the transmitters and receivers have discrete

outputs that indicate if either of the fiber optic links have suffered a loss of the light
signal.

• FOX Extenders Control Program — For RS-232 remote control from a PC, the

Extron FOX Extenders Control Program, which runs under Microsoft® Windows®,
provides a graphical interface and drag-and-drop/point-and-click operation.

• Simple Instruction Set — The transmitter and receiver use the SIS for easy remote

control operation.

• Analog audio level — The analog audio output is at the consumer level (-10 dBV).

• Upgradable firmware — The firmware that controls the operation of each unit can be

upgraded in the field via an RS-232 link without taking the unit out of service. Firmware
upgrades are available for download on the Extron Web site, www.extron.com, and
they can be installed using the FOX Extenders Control Program.

• Memory presets — 30 memory presets are a time-saving feature that lets you store

input size and position settings relative to a specific input resolution. You can then recall
those settings, when needed, using the SIS or the control software.

• Rack mounting — Both FOXBOX HDMI units are rack mountable in any conventional

19-inch wide rack, using an Extron 9.5-inch or 6-inch deep rack shelf.

• Power — The 100 VAC to 240 VAC, 50-60 Hz external power supply for each unit

provides worldwide power compatibility.

NOTES:

• If you connect only one fiber optic cable (item F, on the next page), or you

configure the receiver for daisy-chaining, you will not receive reports from the
controlled device. To receive responses from the controlled device, you must
install two fiber optic cables and leave link 2 enabled (via an SIS command
(see page 25) to the receiver or using the FOX Extenders Control Program

NOTES:

• Ensure that you use the proper fiber cable for your transmitter/receiver pair.

Typically, singlemode fiber has a yellow jacket and multimode cable has an
orange or aqua jacket.

• Only one fiber optic cable, transmitter-Tx-to-receiver-Rx, is required for video,

audio, and serial command transmission. But, if you connect only one fiber
optic cable, or if your receiver is configured to daisy-chain the optical signal:

• The HDMI signal output by the receiver is not HDCP-compliant.

• You will not receive RS-232 reports from the controlled device.
