FOXBOX SR HDMI • Introduction 1
About the FOXBOX SR HDMI
The FOXBOX SR HDMI is an ultra-high performance scaling fiber optic receiver that accepts a
proprietary optical signal on a single LC connector from a compatible fiber optic transmitter
or daisy-chained receiver located up to 30 km (18 miles) away.
The receiver outputs a single link of HDMI video, digital audio (embedded in the HDMI
output), analog audio, and RS-232 serial commands. The receiver can scale its video output
to one of several resolutions and rates.
NOTE: For HDCP compliance:
• A FOXBOX SR HDMI receiver must be paired with a FOXBOX HDMI or
• You must connect both fiber optic cables between the transmitter and
• A signal cannot be daisy-chained and retain HDCP compliance.
• The bidirectional Consumer Electronics Control (CEC) is not supported.
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, or
• 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 from the transmitter.
The single link of HDMI video output by a FOXBOX SR HDMI can be converted to DVI-D
video with the appropriate adapter.
The receiver has built-in color bars, crosshatch, grayscale, alternating pixels, and crop test
patterns, which are available under RS-232 Simple Instruction Set (SIS™) control, to assist in
setting up the display equipment and image and audio adjustments. The receiver has image,
audio, fiber light status, and lost-light alarm indicators.

Cable Transmission Modes
The receiver is further categorized by the type of fiber optic cable, multimode or singlemode,
which defines the effective range of transmission:
• Multimode (MM) — Long distance, up to 2 km (6,560 feet) (depending on the fiber
cable)
• Singlemode (SM) — Very long distance, up to 30 km (18.75 miles)
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.
Ultra high performance — The FOXBOX SR HDMI receives pixel-for-pixel HDMI or DVI-D
(with an adapter) video transmission, up to 1920 x 1200 at 60 Hz.
Video output — The receiver outputs a single link of HDMI video.
Compatible with the FOX Matrix Switchers, and FOX 500, FOXBOX, and
PowerCage FOX transmitters and receivers (with the exception of the FOX DA6,
FOX 2G, and FOX 3G HDSDI products)
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 receiver panel has indicators for monitoring image and audio
transmission and the fiber optic link.
Loss-of-light alarms — The receivers panel has discrete outputs that indicate if either of
the fiber optic links has suffered a loss of the light signal.
Signal Processing Product Control Program — For RS-232 remote control from a PC, the
Extron Signal Processing Product Control Program, which runs under Microsoft® Windows®,
provides a graphical interface with drag-and-drop, point-and-click operation.
Simple Instruction Set — The receiver uses SIS commandsfor easy remote control
operation.
Analog audio level — The analog audio output is at the consumer level (-10 dBV).
Auto Image™ — The auto imaging feature automatically sizes and centers the input to fill
the screen.
Upgradable firmware — The firmware that controls the operation of the receiver 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 website, www.extron.com, and they
can be installed using the Signal Processing Product 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.
LockIt™ HDMI Cable Lacing Bracket — The receiver includes a LockIt bracket to secure
the HDMI cable to the unit.
Rack mounting — The receiver is rack mountable in any conventional 19-inch wide rack,
using an Extron 9.5-inch or 6-inch deep rack shelf.

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. However, 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 Signal
Processing Product Control Program).
Ä Rx — For all one-way video, audio, and serial communications from the transmitter
to the receiver, connect a fiber optic cable to the Rx LC connector.
Connect the free end of this fiber optic cable to the Tx connector on a FOXBOX Tx
transmitter or to any other compatible Extron FOXBOX device.
Å Tx (optional) — Connect a fiber optic cable to the Tx LC connector for either of
the following functions:
Normal configuration — For all one-way return serial communications from the
receiver to the Rx connector on a compatible transmitter (see figure 3).
Daisy chain configuration — For daisy-chained video, audio, and serial
communications to the Rx connector on another receiver (see figure 4).
NOTE: The Tx connector emits light in either case and the Rx port receives light.
Connect the free end of this fiber optic cable to either of the following:
• The Rx connector on a compatible transmitter or to any other compatible Extron
FOX device
• The Rx connector on another receiver in the daisy chain
Tx Link and Rx Link LEDs — When lit, the link is active (light is received).

HDMI signals run at a very high frequency and are especially prone to errors caused by bad
video connections, too many adapters, or excessive cable length. To avoid the loss of an
image or jitter, follow these guidelines:
• Do not exceed 16.4 feet (5 meters) on the input of the transmitter or the output of the
FOXBOX SR HDMI scaling receiver.
• Use only the cable designed for HDMI signals that is supplied by Extron.
• Limit or avoid the use of adapters.
• Use only cables specifically intended for HDMI or DVI signals. Use of non-HDMI or
non-DVI cables or modified cables can result in a missing video output.
To securely fasten an HDMI cable to a device:
1. Plug the HDMI cable into the panel connection (see a in figure 6).

3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then
tighten the screw to secure the bracket (c).
ATTENTION: Do not overtighten the HDMI connector mounting screw. The shield
to which it fastens is very thin and can easily be stripped.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket (d).
5. While holding the connector securely against the lacing bracket, use pliers or similar
tools to tighten the tie wrap, then remove any excess length (e).
RS-232 connections
The Remote RS-232 port on the receiver only is for remote control of the receiver. The
RS-232 Over Fiber port on both units is for transmission of serial signals, such as projector
control signals, between the transmitter and receiver (see figure 7 to properly wire the
connectors).
