Figure 1. Typical FOXBOX Tx/Rx HDMI Application

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 3.5mm 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.

Both Units

The transmitter and receiver have many controls, including image and audio adjustments, that are available under RS-232 Simple Instruction Set (SISTM) 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 @ 60 Hz. 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.

NOTES:

• Although the receiver can operate with non-HDMI transmitters, the video output is not HDCP-compliant.
• The transmitter and receiver are not compatible with the FOX AV, PowerCage FOX AV, FOX 3G HD-SDI, PowerCage FOX 3G HD-SDI, and FOX 3G DVC models.

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.

Making Connections

HDMI connector

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 or buffered loop-through of the FOXBOX HDMI transmitter or the output of the FOXBOX HDMI 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 figure 8, ①).

Figure 8. Installing the LockIt Lacing Bracket

1. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing bracket to be placed over it (2). The screw does not have to be removed.

2. Place the LockIt lacing bracket on the screw and against the HDMI connector, then tighten the screw to secure the bracket (③).

ATTENTION:

• Do not overtighten the HDMI connector mounting screw. The shield to which it fastens is very thin and can easily be stripped.

• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel elle est attachée est très fin et peut facilement être dénudé.

• Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as shown (④).

• While holding the connector securely against the lacing bracket, use pliers or similar tools to tighten the tie wrap, then remove any excess length (⑤).

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 9 to properly wire the connectors.

NOTE: Cross the Tx and Rx lines once between the source and the target.

Figure 9. RS-232 Over Fiber Connector

NOTE: The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).

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

Alarm outputs connection

Figure 10. Alarm Connector

NOTE: The length of exposed wires is critical (see the RS-232 connector NOTE above.)

Audio output connector

See figure 11 to properly wire a captive screw output connector. The connector is included with transmitter, but you must supply the audio cable. Use the supplied tie-wrap to strap the audio cable to the extended tail of the connector.

Figure 11. Captive Screw Connector Wiring for Stereo Audio Output

ATTENTION:

• For unbalanced audio, connect the sleeves to the ground contact. DO NOT connect the sleeves to the negative (-) contacts.
• Pour l'audio asymétrique, connectez les manchons au contact au sol. NE PAS connecter les manchons aux contacts négatifs (-).

NOTE: The length of exposed wires is important (see the RS-232 connector NOTE on the previous page for more information.)

Front panel Configuration ports

NOTE: These ports are for remote control of the unit, not for the over fiber RS-232 link.

The Configuration ports on the transmitter and receiver are 2.5 mm mini stereo jacks. The 9-pin D to 2.5 mm mini jack TRS RS-232 cable, included with the transmitter, can be used for this connection.

9-pIn D Connection TRS Plug

Pin 2 Rx line on the computer Tip

Pin 3 Tx line on the computer Ring

Pin 5 Signal ground on the computer Sleeve

Figure 12. 9-pin TRS RS-232 cable

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

9600 baud
- 1 stop bit

- no parity

8 data bits

- no flow control

NOTE: The maximum distances to the controlling device can vary up to 200 feet (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 feet (15 m) are typically not a problem. In some cases, the unit may be capable of serial communications via RS-232 up to 250 feet (76 m) away.

See Remote Control on page 18 for definitions of the SIS commands (serial commands to control the transmitter via the Configuration port) and software control.

Power supply wiring

ATTENTION:

Figure 13 shows how to wire the connector. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Figure 13. Power Connector Wiring

CAUTION:

ATTENTION :

- The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).

• Any longer and the exposed wires may touch, causing a short circuit between them.
• Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws.

- Do not tin the power supply leads before installing them in the connector. Tinned wires are not as secure in the connector and could be pulled out.

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

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 Extron website for the Extron office nearest you.

To take advantage of the various adjustments and test patterns available in the FOXBOX, you need to connect a computer or other RS-232 capable device to the front panel Configuration port on either unit or the rear panel Remote RS-232 port on the receiver and operate using either SIS commands or the FOX Extenders Control Program (see Remote Control on page 18).

Troubleshooting — If No Image Appears

1. Ensure that all devices are plugged in and powered on. The transmitter and receiver are receiving power if their power LEDs are lit.
2. Ensure an active input is applied to the transmitter. The transmitter is receiving an active input if the HDMI LED is lit.
3. Ensure that the proper signal format is supplied.
4. Check the cabling and make corrections as necessary.
5. Call the Extron S3 Sales & Technical Support Hotline if necessary (see www.extron.com for the phone number in your region of the world).

Remote Control

This section includes:

• Simple Instruction Set Control
• FOX Extenders Control Program

The transmitter and receiver each have a front panel Configuration port, a 2.5 mm mini stereo jack (see Front panel Configuration ports on page 14). The receiver has a rear panel Remote RS-232 port, a 3-pole captive screw connector (see RS-232 connections on page 13). Any of these ports can be connected to a host device such as a computer running the HyperTerminal or DataViewer utility, or a control system to make serial control of the transmitter and receiver possible.

The default serial port protocol for all ports is as follows:

9600 baud

- No parity

8-bit

- No flow control

- 1 stop bit

NOTE: RS-232 commands and FOX Extenders Control Program functions are transmitter- or receiver-specific or may have different responses depending on the unit connected. You must connect to the appropriate device for the command or function to work properly or to get the expected response.

Simple Instruction Set Control

Host-to-Unit Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device. All responses from the transmitter or receiver to the host end with a carriage return and a line feed (CR/LF = ←), which signals the end of the response character string. A string is one or more characters.

Symbol Definitions for Transmitter SIS Commands

← = CR/LF (carriage return/line feed)
← = Carriage return (no line feed)

| = Pipe (can be used interchangeably with the character)

- = Space (hard) character

Esc = Escape key (hex 1B)

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 unit-initiated messages are listed below:

(c) Copyright 20nn, Extron Electronics FOXBOX Tx HDMI, Vx.xx, 60-1174-xx

- or -

(c) Copyright 20nn, Extron Electronics FOXBOX Rx HDMI, Vx.xx, 60-1174-xx

The connected unit issues the appropriate copyright message (above) when it first powers on. Vx.xx is the firmware version number; 60-1174-xx is the part number of the connected unit.

Reconfig

The unit sends the Reconfig message whenever the video input signal to the transmitter is changed.

1LnkX12•2LnkX12•VidX12•AudX12

The unit sends the status message whenever a change in the fiber link and video connection occurs.

EmbedAudX10

The unit sends the Embedded audio message whenever a change in the position of the receiver rear panel HDMI Audio switch occurs.

Error Responses

When the unit receives a valid SIS command, it executes the command and sends a response to the host device. If the switcher is unable to execute the command because the command is invalid or it contains invalid parameters, the transmitter or receiver 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 configuration

Timeout

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

• Only one fiber optic cable, transmitter-Tx-to-receiver-Rx, is required for serial command transmission. But, if you connect only one fiber optic cable, the transmitter will not receive reports from the controlled device. For the transmitter to receive responses from the controlled device, you must install two fiber optic cables and leave link 2 enabled (via an SIS command (see page 25) to the receiver or using the FOX Extenders Control Program (see page 34).

Using the Program

Status panel

Figure 19. Status Panel

The Status panel provides indications of the connection status.

• HDMI indicator — This indicator is green when the transmitter detects a sync signal on its HDMI video input
• Audio indicator — This indicator is green when the transmitter detects a low level audio signal for a short period. This indicator goes dark if the audio signal drops below the minimum threshold for a short period.
• Link 1 indicator — This indicator is green when the receiver detects light on the fiber optic cable connected to the Tx port.

NOTE: The receiver detects the transmitter-Tx-to-receiver-Rx light. It reports the status to the transmitter via the optional Rx cable.

If the PC is connected to the transmitter and either the secondary (receiver-Tx-to-transmitter-Rx) cable is not connected in your system or the receiver is in the daisy chain mode, the Link 1 indicator in the control program does 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 fiber optic cable connected to the Rx port.

NOTE: The transmitter detects the receiver-Tx-to-transmitter-Rx light. It reports the status to the receiver via the Tx cable.

If the PC is connected to the receiver and either the primary (transmitter-Tx-to-receiver-Rx) cable is disconnected or the receiver is in the daisy chain mode, the Link 2 indicator in the control program will not show green (detected), whether the transmitter detects the link or not.

The Status panel also shows to which unit the controlling PC is connected, the FOXBOX model (multimode or singlemode), the internal temperature, and the video input frequency. The Other side entry cannot be read when connected to a FOXBOX HDMI.

Control tab functions

Equipment Mounting

This section provides procedures for mounting the transmitter and receiver.

Mounting the Unit

ATTENTION:

Either of the 1-inch high, quarter-rack width (transmitter) or half-rack width (receiver) units can be placed on a tabletop, mounted on a rack shelf, or mounted under or through a desk or other furniture. The receiver can be mounted to a projector bracket.

Tabletop Use

Affix the included rubber feet to the bottom of the unit and place it in any convenient location.

Mounting kits

Mount the unit using any optional compatible mounting kit listed on the Extron website (www.extron.com), in accordance with the directions included with the kit. For rack mounting, see "UL Rack-Mounting Guidelines," below.

UL Rack-Mounting Guidelines

The following Underwriters Laboratories (UL) requirements pertain to the installation of the unit into a rack.

• Elevated operating ambient temperature — 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 = +122 °F, +50 °C) specified by Extron.
• Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
• 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 use of power strips).
