FOXBOX 4G Tx/Rx • Quick Start Guide

Quick Start Guide — FOXBOX 4G Tx/Rx

QS-1

Step 1

Turn all of the equipment off or disconnect it from the power source.
If desired, mount the FOXBOX 4G units in a rack or furniture, or
place them on desktops.

Step 2

FOXBOX 4G Tx VGA: Connect a VGA to UXGA
source to the transmitter's RGB Input 15-pin HD
connector.

FOXBOX 4G Tx DVI: Connect a digital visual
interface (DVI-D) source to the transmitter's
DVI-D Input connector.

Step 3

Connect an unbalanced, stereo or mono audio input to the
transmitter's Audio Input 3.5 mm mini jack.

Step 4

If you want the FOXBOX 4G to pass serial data and/or
control signals, such as for serial control of a projector,
connect the host device to the transmitter and the
controlled device to the receiver via three poles of the
RS-232 Over Fiber captive screw connector on both units.

N

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
transmitter is configured to daisy chain the optical signal,
system functionality is reduced.
You will not receive RS-232 reports from the controlled device,
and some Windows-based control program functions and
RS-232 commands will not work. To receive responses from
the controlled device and for full functionality, you need to
install both fiber optic cables and leave the FOXBOX receiver
in normal configuration (the receiver's Mode DIP switch 1
down). See Step 7.

Step 5

For remote monitoring of the status of the optical links,
connect a locally constructed or obtained device to the two
Alarm poles of the units' RS-232/Alarm 5-pole captive
screw connectors. The two poles are shorted together
when no light is detected.

N

The transmitter's Alarm port reports the status of

the Rx light link.
The receiver's Alarm port reports the status of the
Tx light link.

In this manual, the term "FOXBOX 4G" refers to

either an analog RGB video or a DVI video unit. Where
differences exist between the VGA and DVI models, the
unit's full name is used.

About the FOXBOX 4G Tx/Rx

General system operation

The FOXBOX 4G VGA transmitter inputs VGA - UXGA RGB
video.

The FOXBOX 4G DVI transmitter inputs a single link of DVI
video.

Both transmitters input audio and one-way (transmitter-to­receiver) RS-232 serial communication (for applications such as
projector control). The transmitters convert all of their inputs
into a proprietary signal; and output the signal on a single ber
optic cable to the receiver. An optional return (receiver-to­transmitter) stream of serial RS-232 communications, such as
projector responses, requires a second ber optic cable. Rather
than the return RS-232 communications, the receivers can be
congured to output a daisy-chained primary ber optic signal
to another receiver.

FOXBOX 4G Tx/Rx • Introduction

1-5

The FOXBOX 4G VGA receiver outputs VGA - UXGA RGB
video.

The FOXBOX 4G DVI receiver outputs a single link of DVI
video.

The receivers convert the proprietary signal(s) back to video
(either RGB or DVI as applicable to the model), audio, and
serial RS-232 communication, and output the signals locally.
If either RS-232 return or daisy-chained communications are
implemented (a second ber optic cable is installed), the receiver
outputs a proprietary serial communication signal on the second
ber optic cable. For video resolutions up to 1600 x 1200, the
receiver's video output is a perfect, pixel-for-pixel recreation of
the video signal input to the transmitter.

The transmitter and receiver have image and audio adjustments
available under RS-232 control. Both units have image, audio,
and ber light status and lost-light alarm indicators.

The FOXBOX 4G VGA transmitter can handle an RGBHV, RGBS,
RGsB, or RsGsBs input signal. The FOXBOX 4G VGA receiver
can output RGBHV or RGsB, as selected by the user.

The receivers have built-in alternating pixels, Color Bars,
and grayscale test patterns to assist in setting up the display
equipment.

The FOXBOX 4G transmitters and receivers are rack and
furniture mountable and have external power supplies that
provide worldwide power compatibility.

N

The FOXBOX 4G DVI does not support the

transmission of signals with High-bandwidth Digital
Content Protection (HDCP).

N

A FOXBOX 4G Tx VGA transmitter is fully

compatible with a FOXBOX 4G DVI Rx receiver.

A FOXBOX 4G DVI Tx transmitter is fully
compatible with a FOXBOX 4G Rx VGA receiver.

The FOXBOX 4G units are fully compatible with all
Extron FOX 500 products and a variety of other fiber
optic products. Those other products are identified where
appropriate, but not specifically described in this manual.

Cable transmission modes

The transmitters and receivers are further categorized by the
type of ber optic cable, multimode or singlemode, which dene

compatible — Enables ultra-long distance

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

Compatible with FOX 500 DA6 distribution amplifier and

Fiber Matrix 6400 matrix switcher

Audio input — The transmitters accept a balanced or

unbalanced stereo audio input on a 3.5 mm mini jack.

Audio input gain/attenuation — The input audio level can be

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

Audio output — Balanced or unbalanced stereo audio is output

from the receivers on a 3.5 mm mini jack.

Links monitoring — The transmitters' and receivers' front

panels have indicators for monitoring image and audio
transmission and both ber optic links.

Loss-of-light alarms — The transmitters' and receivers' rear

panels have discrete outputs that indicate if either of the
ber optic links have suffered a loss of the light signal.

Windows®-based control program — For RS-232 remote control

from a PC, the Extron Windows-based FOX Extender
control software provides a graphical interface and drag­and-drop/point-and-click operation.

Simple Instruction Set (SIS™) — The transmitters and receivers

use Extron’s SIS for easy remote control operation.

Audio level — The audio output is at the consumer level

(-10 dBV).

Upgradable firmware — The rmware that controls each unit's

operation can be upgraded in the eld 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
Windows-based control program.

Memory presets — 30 memory presets are a time-saving

feature that lets you store input size and position settings
relative to a specic input resolution. You can then recall
those settings, when needed, using the SIS or the control
software.

Rack mounting — All FOXBOX 4G Tx and Rx units are rack

mountable in any conventional 19" wide rack, using
Extron's 9.5" or 6" deep rack shelf.

Power — Each unit's 100 VAC to 240 VAC external power

supply provides worldwide power compatibility.

Installation and service must be performed by

authorized personnel only.

Any of the 1" high, quarter-rack width units can be placed on a
tabletop, mounted on a rack shelf, or mounted under or through
a desk or other furniture.

The FOXBOX 4G units generate heat during

operation. Ensure there is ample room between
units in multiple unit installations for ventilation
and/or ensure adequate equipment cooling. Units
too close together may overheat.

Tabletop placement

Afx the four included rubber feet to the bottom of the unit and
place it in any convenient location.

Rack mounting

UL guidelines

The following Underwriters Laboratories (UL) guidelines
pertain to the installation of a FOXBOX 4G transmitter or
receiver into a rack (gure 2-1).

1. Elevated operating ambient — If installed in a closed

or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater
than room ambient. Therefore, consider installing the
equipment in an environment compatible with the
maximum ambient temperature (Tma) of +122 °F (+50 °C)
specied by Extron.

2

. Reduced air flow — Installation of the equipment in a rack

should be such that the amount of air ow required for
safe operation of the equipment is not compromised.

3. Mechanical loading — Mounting of the equipment in

the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.

4. Circuit overloading — Consideration should be given to

the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on
overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be
used when addressing this concern.

5

. Reliable earthing (grounding) — Reliable earthing

of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections
other than direct connections to the branch circuit (such as
the use of power strips).

Mounting instructions

For optional rack mounting, mount any of the 1" high, quarter
rack width units on any of the following rack shelves:

• RSU 126 6" deep universal rack shelf kit (part #60-190-10)

• RSB 126 6" deep basic rack shelf (part #60-604-10)
