FOXBOX Tx/Rx HDMI • Introduction 1

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.

Transmitter

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.

Receiver

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.

FOXBOX Tx/Rx HDMI • Introduction 2

Both Units

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 @ 60Hz. 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.

Cable transmission modes

The transmitter and receiver are further categorized by the type of fiber optic cable, multimode or singlemode, which define the effective range of transmission:

• Multimode — Long distance, up to 2 km (6,560 feet) (depending on the fiber cable)

• FOXBOX Tx HDMI MM

• FOXBOX Rx HDMI MM

• Singlemode — Very long distance, up to 30 km (18.75 miles)

• FOXBOX Tx HDMI SM

• FOXBOX Rx HDMI SM

NOTE: The multimode and singlemode units are physically and functionally identical,

with the exception of the effective range of transmission. In this manual, any reference applies to either transmission mode unless otherwise specified.

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.

f Fiber optic connectors and LEDs —

CAUTION: These units output continuous invisible light, which may be harmful to

the eyes; use with caution. For additional safety, plug the attached dust caps into the optical transceivers when the fiber cable is unplugged.

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.

To receive responses from the controlled device and for HDCP

compliance, you need to install both fiber optic cables and leave link 2 enabled (via an SIS command to the receiver or using the FOX

Extenders Control Program).
