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.

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.

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.

Step 6

Connect the primary (transmitter Tx to receiver Rx) (required) ber cable between the Tx connector on the transmitter and Rx connector on the receiver.

Only the primary cable is required for video,

audio, and serial command transmission. The secondary cable is required only to return serial data from the controlled device to the host device. For the return data, the receiver must also be in normal conﬁguration.

For normal conﬁguration with serial return,

perform step 7 and skip step 8. For daisy chain conﬁguration, skip step 7 and perform step 8.

Step 7a (normal conﬁguration)

Connect the secondary ber cable between the Tx connector on the receiver and Rx connector on the transmitter. See the drawing above.

Step 7b

Set the receiver's Mode DIP switch 1 down.

Step 8a (daisy chain conﬁguration)

Connect the receiver's Tx output to the Rx input on another receiver. See the drawing at right.

Step 8b

Set the receiver's Mode DIP switch 1 up.

Step 9a

FOXBOX 4G Rx VGA: Connect an RGBHV or RGsB display to the receiver's RGB Output 15-pin HD connector.

FOXBOX 4G Rx DVI: Connect a DVI display to the receiver's DVI-D Output connector.

Step 10

Connect balanced or unbalanced stereo or mono audio devices to the receiver, using the Audio Outputs 3.5 mm mini jack.

Step 11

For serial control of the transmitter's and receiver's adjustment and test pattern functions, connect a host device to either unit's front panel Conguration connector via the included TRS RS-232 cable.

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.

The FOXBOX 4G DVI does not support the

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

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 the effective range of transmission:

• Multimode — Up to 150 m (450')

 FOXBOX 4G Tx VGA MM  FOXBOX 4G Rx VGA MM  FOXBOX 4G Tx DVI MM  FOXBOX 4G Rx DVI MM

• Singlemode — Very long distance, up to 30 km

(18.75 miles)

 FOXBOX 4G Tx VGA SM  FOXBOX 4G Rx VGA SM  FOXBOX 4G Tx DVI SM  FOXBOX 4G Rx DVI SM

The multimode and singlemode products 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.

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.

Mounting the Unit

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.

. 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.

. 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)

DVI signals run at a very high frequency and are especially prone to 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 or buffered loop-through of the FOXBOX 4G DVI transmitter or the output of the FOXBOX 4G DVI receiver.

• Use only the cable designed for DVI signals that is supplied by Extron.

• Limit or avoid the use of adapters.

• Use only approved DVI/HDMI connectors.

Use only cables speciﬁcally intended for DVI or HDMI

interfaces. Use of non-DVI or non-HDMI cables or modiﬁed cables can result in a missing video output.

This port is RS-232 only, with the following protocols:

• 9600 baud • no parity • 8 data bits

• 1 stop bit • no ow control

The maximum distances from the transmitter or receiver

to the controlling device can vary up to 200' (61 m). Factors such as cable gauge, baud rates, environment, and output levels (from the unit and the controlling device) all affect transmission distance. Distances of about 50' (15 m) are typically not a problem. In some cases, the unit may be capable of serial communications via RS-232 up to 250' (76 m) away.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

The two power cord wires must be kept separate

while the power supply is plugged in. Remove power before wiring.

The length of the exposed (stripped) wires is

important. The ideal length is 3/16" (5 mm).

Longer bare wires can short together. Shorter wires are not as secure in the connectors and could pull out.

Do not tin the leads before inserting them in the

Operation

After the transmitter, all receivers, and their connected devices are powered up, the system is fully operational. If any problems are encountered, verify that the cables are routed and connected properly, and that all display devices have identical resolutions and refresh rates. If your problems persist, call the Extron S3 Sales & Technical Support Hotline. See the contact numbers on the rear of this manual for the Extron ofce nearest you.

To take advantage of the FOXBOX 4G's various adjustments and test patterns, you need to connect a computer or other RS-232 capable device to either unit's front panel Conguration port and operate using either SIS commands or the FOX Extender Windows-based control program.

The transmitter and receiver each have a front panel Conguration (RS-232) port, a 2.5 mm mini stereo jack, that can be connected to a host device such as a computer running the HyperTerminal or other utility, an RS-232 capable PDA, or a control system. These ports make serial control of the transmitter and receiver possible.

The protocol for the ports on both units is as follows:

• RS-232 • 9600 baud • no parity

• 8 data bits • 1 stop bit • no ow control

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 you conﬁgure the receiver for daisy-chaining, you will not receive RS-232 reports from the controlled device, and there will be reduced RS-232 command functionality on the Rx unit. 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).

Simple Instruction Set Control

Host-to-interface communications

SIS commands consist of one or more characters per eld. No special characters are required to begin or end a command character sequence. When a command is valid, the unit executes the command and sends a response to the host device.

Unit-initiated messages

When a local event, such as an equipment power-up, occurs, the unit responds by sending a message to the host. The unitinitiated messages are listed below:

- or -

Vx.xx, 60-935-xx]]

- or -

Vx.xx, 60-935-xx]]

The connected unit issues the appropriate copyright message (above) when it rst powers on. Vx.xx is the rmware version number; 60-93x-xx is the connected unit's part number.

The unit sends the DIP switch position message whenever a change in the receiver's DIP switch settings occurs.

Only DIP switch 1 (the ﬁrst X$) has any effect on the

system operation. When the switch is on (up), the receiver is in daisy chain mode.

Error responses

When the unit receives a valid SIS command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command is invalid or it contains invalid parameters, the unit returns an error response to the host. The error response codes are:

E10 - Invalid command] E11 - Invalid preset number] E13 - Invalid parameter] E14 - Invalid command for this conguration]

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The command operation is aborted with no other indication.

Using the command/response table

The command/response table begins on page 3-6. Either

uppercase or lower case letters are acceptable in the command eld except where indicated for the audio level (gain and attenuation) commands. Symbols are used

throughout the table to represent variables in the command/ response elds. Command and response examples are shown throughout the table. The ASCII to HEX conversion table below is for use with the command/response table.

Windows®-Based Program Control

The Extron FOX Extender program, which communicates with the transmitter and receiver pair via either unit's rear panel Remote RS-232 port or front panel Conguration port, provides an easy way to operate the pair.

The program is compatible with Windows 2000, Windows XP, or later. Updates to this program can be downloaded from the Extron Web site (www.extron.com).

Installing the software

The program is contained on a CD-ROM. To install the software, insert the CD-ROM into the drive. The setup program should start automatically. If it does not self-start, run Launch.exe from the CD and follow the instructions that appear on the screen. By default, the Windows installation creates a C:\Program Files\Extron\FOX_Extenders directory, and it places four icons into a group folder named “Extron Electronics\FOX Extender WCP.” The four installed icons are:

• Check for FOX Extender updates

• FOX Extender WCP

• FOX Extender Help

• Uninstall FOX Extender WCP

Starting the program

Start the Extron FOX Extender program as follows:

. Click Start > Programs > Extron Electronics >

FOX Extender WCP > FOX Extender WCP.

The Communication Setup window appears (gure 3-1).

Figure 3-1 — Communication Setup window

2. Select the Com port to which your transmitter or receiver

is connected. Click OK.

The FOX Extender program window appears (gure 3-2).

Figure 3-2 — FOX Extender program window

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, there will be reduced Windows-based control program functionality on the Rx unit. For full functionality, you need to install both ﬁber optic cables and leave the FOXBOX receiver in normal conﬁguration (Mode DIP switch 1 down).

Status area

The status area provides visual indications of the connection status.

• RGB indicator — This indicator is green when the

transmitter detects a sync signal on its video input:

 Horizontal sync (H) (for RGBHV video)  Composite sync (S) (for RGBS video)  Green (Sync on green) (G) (for RGsB or RsGsBs video)  DVI video

• Audio indicator — This indicator is green when the

transmitter detects a low level audio signal for a short period of time. This indicator goes dark if the audio signal drops below the minimum threshold for a short period of time.

• Link 1 indicator — This indicator is green when the

receiver detects light on the ber optic cable Tx.

The receiver detects the transmitter Tx to receiver Rx

light. It reports the status to the transmitter via the optional Rx cable.

If you are connected to the transmitter's Conﬁguration port, and the secondary (receiver Tx to transmitter Rx) cable is not connected in your system or the receiver is in the daisy chain conﬁguration, the control program's Link 1 indicator will not show green (detected), whether the receiver detects the link or not.

• Link 2 (Optional) indicator — This indicator is green

when the transmitter detects light on the ber optic cable Rx.

The transmitter detects the receiver Tx to transmitter

Rx light. It reports the status to the receiver via the Tx cable.

If you are connected to the receiver's Conﬁguration port, and the primary (transmitter Tx to receiver Rx) cable is disconnected or the receiver is in the daisy chain conﬁguration, the control program's Link 2 indicator will not show green (detected), whether the transmitter detects the link or not.

The Status area also shows to which unit the controlling PC is connected, the FOXBOX 4G model (multimode or singlemode), the internal temperature, and the video input frequency. The "Other Side" entry is the device connected to the far end of the ber optic cable.

Memory Preset area

The Memory Preset area provides a means to save and recall memory presets. Memory presets are stored values of the horizontal and vertical position and sizing information saved in nonvolatile memory. When the FOXBOX 4G is powered down and later powered back up, the settings are available for selection using the Recall button. Saving the settings to a preset using the Save button overwrites the settings previously written to that preset.

Mute area

Click the Video Mute and/or Audio Mute radio buttons in the Mute area to turn the video and/or audio mutes on and off.

When the video output is RGB and the output is muted,

the receiver mutes the red, green, and blue planes, but leaves the sync plane(s) (horizontal and vertical or composite sync) live so that there is no loss of sync in the display device.

When you mute or unmute the output, the setting is

changed in the receiver. It reports the changes to the transmitter via the optional receiver Tx to transmitter Rx cable.

If you are connected to the transmitter's Conﬁguration port, and the receiver Tx to transmitter Rx cable is not connected in your system or the receiver is in the daisy chain conﬁguration, you can still mute the output in the control program's Mute area, but the program cannot report the position values. The Set video (or audio) mute On or Off message is displayed for approximately 1 second (ﬁgure 3-3).

Speciﬁcations

The FOXBOX 4G DVI and FOXBOX 4G VGA consist of

a transmitter (FOXBOX 4G DVI/VGA TX) and a receiver (FOXBOX 4G DVI/VGA RX) with one or two ﬁber optic cables linking the two units. They are available in singlemode or multimode versions.

For the VGA models, the analog RGB input signal is digitized

pixel for pixel in the transmitter, sent digitally through the ﬁber cable, and converted back to analog RGB 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.

These transceivers are class 1 laser products. They meet the

safety regulations of IEC-60825, FDA 21, CFR 1040.10, and FDA 21 CFR 1040.11.

Optical ﬁber interconnection between transmitter and receiver

Number/type ................................ 1 or 2 ber optic
