About this Guide

This guide contains information about the PowerCage FOX Tx/Rx AV ﬁber optic extenders, with instructions for experienced installers to install, conﬁgure, and operate the equipment. Unless otherwise speciﬁed, references in this manual to the “AV board” or “PowerCage FOX AV” relate to the features or operation of the PowerCage FOX Tx/Rx AV.

The term “transmitter” refers to both multimode and singlemode transmitters and “receiver” refers to both multimode and singlemode receivers.

About the PowerCage FOX Tx/Rx AV Transmitter and Receiver

The Extron PowerCage FOX Tx/Rx AV Fiber Optic Extenders consist of a modular transmitter and receiver board pair for the PowerCage enclosure, providing long distance transmission of standard deﬁnition video, audio, and data (RS-232) signals over a ﬁber optic cable at rates of up to 2 Gbps.

The double-slot board design of the PowerCage FOX Tx/Rx AV allows for up to eight transmitters or receivers to be installed in the PowerCage enclosure. The PowerCage FOX Tx/Rx AV transmitter and receiver are hot-swappable, meaning that the boards can be replaced or upgraded without the need to power down the system.

The 1310 nm singlemode module of the PowerCage FOX Tx/Rx AV board carries signals up to 30 km (18.75 miles) while the 850 nm multimode module carries signals up to 2 km (6561 feet).

NOTE: The transmitter and receiver must be compatible. Both must be singlemode or

both must be multimode in order to transmit a readable signal.

PowerCage FOX Tx/Rx AV • Introduction 1

System Compatibility

The PowerCage FOX Tx/Rx AV video units are compatible with the FOX Tx/Rx AV ﬁber optic video transmitter and receiver and with the FOX Series distribution ampliﬁers, switchers, and matrix switchers. However, they are not compatible with the following Extron products:

z FOXBOX z FOX 500 (RGB) and FOX 500 DVI z FOX 500 DA6 z FOX 3G HD-SDI z PowerCage FOX 3G HD-SDI Series z PowerCage FOX VGA and DVI

Cable Transmission Modes

The transmitters and receivers are further categorized by the type of ﬁber optic cable, multimode or singlemode, which deﬁnes the effective range of transmission:

z Multimode — Long distance: up to 2 km (6,561 feet) (depending on the ﬁber cable)

z PowerCage FOX Tx AV MM z PowerCage FOX Rx AV MM

z Singlemode — Very long distance: up to 30 km (18.75 miles)

z PowerCage FOX Tx AV SM z PowerCage FOX Rx AV SM

NOTE: The multimode and singlemode products are physically and functionally

identical, except for the effective range of transmission. In this guide, any reference applies to either transmission mode unless otherwise speciﬁed.

General System Operation

The PowerCage FOX Tx/Rx AV transmitter accepts a single low resolution video signal (composite, S-video, or low resolution component video). It accepts audio and one-way (transmitter-to-receiver) RS-232 serial communication (for applications such as projector control). The transmitter converts all of its incoming signals into a proprietary format signal, which it outputs on a single ﬁber optic cable to the PowerCage FOX Rx AV receiver. An optional return (receiver-to-transmitter) stream of serial RS-232 communications, such as projector responses, requires a second ﬁber optic cable. Instead of the return RS-232 communications, the receiver can be conﬁgured to output a daisy-chained primary ﬁber optic signal to another receiver.

The PowerCage FOX Tx/Rx AV receiver outputs a single low resolution video signal (composite, S-video or low resolution component video), which is not compatible with RGB or HDTV 480p, 720p, or 1080i component video signals. The receiver converts the proprietary signal back to video, audio, and serial RS-232 communication (matching the display requirements) and outputs the signals locally. The Extron Simple Instruction Set (SIS™) commands are used to conﬁgure the receiver to convert between signal formats. If either RS-232 return or daisy-chained communications are implemented (a second ﬁber optic cable is installed), the receiver outputs a proprietary signal on the second ﬁber cable.

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

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

PowerCage FOX Tx/Rx AV • Introduction 2

Features

Digitized signal transmission — Digitized transmission ensures perfect signal transmission. The non-linearity of the ﬁber components does not affect signal quality. Light can be distributed and repeated without signal degradation or compression.

Long distance transmission — Signals may be transmitted up to 2 km (6561 feet) over multimode (MM) ﬁber or up to 30 km (18.75 miles) over singlemode (SM) ﬁber.

Daisy chain capability — The system can be expanded to provide output for up to 10 display devices.

Integration friendly — A variety of connectors permits input and output of composite, S-video, or low resolution component video signals. Compatibility with the Extron ﬁber matrix switchers allows the units to be integrated into more complex A/V systems.

Transmits multiple signal types — Video, audio and data signals can all be transmitted simultaneously over one ﬁber. The units transmit composite, S-Video, or low resolution component video signals and are compatible with NTSC, PAL, and SECAM standards.

All digital, zero compression technology — The PowerCage FOX Tx/Rx AV delivers uncompressed pixel-for-pixel transmission of video signals to ensure optimal image quality.

Auto Input Format Detection — The PowerCage FOX Tx/Rx AV transmitter can be set to detect the incoming video signal format, automatically reconﬁguring itself to transmit the signal. This feature can reduce the number of required outputs for a matrix switcher, lowering system cost while improving manageability.

Encoding and decoding — The PowerCage FOX Tx AV converts incoming signals to a proprietary format that is passed along the ﬁber optic cable to the PowerCage FOX Rx AV. At the other end of the cable, the receiver converts the signal to the low resolution format that matches the needs of the display device.

Output Video Formatting — You can set the output video signal format (composite, S-Video, or component) or follow the format of the source device (video follow).

Picture and audio adjustments — Available picture adjustments include color, tint, contrast, and brightness. Audio adjustments include input gain and attenuation, and output level. Both audio and video can be muted.

Troubleshooting features — A variety of LED signals and indicators allow easy diagnosis of problems.

Easy conﬁguration — The units can be conﬁgured using SIS commands or the FOX Extenders Control Program.

CAUTIONS: The length of the exposed wires in the stripping process is critical.

The ideal length is 3/16 inch (5 mm). If it is any longer, the exposed wires may touch, causing a short circuit between them. If the stripped portion is any shorter, the wires can be easily pulled out even if tightly fastened by the captive screws.

Do not tin the wires. Tinned wire does not hold its shape and can

become loose over time.

The table below shows the initial gain differences between audio input and output using captive screw connectors. The gain for unbalanced output from the captive screw connector is half (-6 dB), regardless of input.

Input Output Gain

Balanced Balanced 0 dB (unity) Balanced Unbalanced -6 dB (half) Unbalanced Balanced 0 dB Unbalanced Unbalanced -6 dB

You can make additional adjustments to audio gain and attenuation using SIS commands. See “SIS Control” in the “Remote Communication and Control” section.

PowerCage FOX Tx/Rx AV • Installation and Operation 8

SIS commands for the PowerCage FOX Tx/Rx AV are shown in the “Remote

Communication and Control” section.

NOTE: Both RS-232 Remote and RS-232 Over Fiber signals require ﬁber optic

Link 1 and Link 2 for full functionality. If only Link 1 is enabled, the ability to conﬁgure the system through

SIS commands is limited by the lack of return communication from the receiver to the transmitter.

• All conﬁguration carried out using the transmitter is processed normally

because only ﬁber Link 1 is required for it.

• Queries from the transmitter about the status of receiver settings are

not processed correctly because ﬁber Link 2 is required to carry the return signal.

• The receiver cannot be used to conﬁgure the transmitter because ﬁber

Link 2 is required.

Lack of communication between the transmitter and the receiver can result in mismatches in the value settings of the two units, which may cause confusion with control systems or software applications. To avoid this, within 4 seconds of Link 2 becoming active, the receiver settings are automatically copied to the transmitter to ensure that settings for both units match.

NOTE: When the receiver settings are copied to the transmitter, existing

transmitter settings are overwritten and it may be necessary to update those values.

d RS-232 Over Fiber connections — The RS-232 Over Fiber connections allow

pass-through to remote units. Wire the Over Fiber portion of the 5-pole captive screw connector as shown below:
