ESD Warning

Warning sign depicting a hand holding an object, enclosed in a triangle (no text or symbols)

To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before touching any internal materials.

When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive smocks, and conductive work mats are specifically designed for this purpose.

Anyone performing field maintenance on AMX DXLink equipment should use an appropriate ESD field service kit complete with at least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another ground cord. These items should not be manufactured locally, since they are generally composed of highly resistive conductive materials to safely drain static charges, without increasing an electrocution risk in the event of an accident.

Compatibility Note: The Transmitters and the Receiver listed above are compatible with a number of other DXLink products (see the section "Product Compatibility Tables" on page 8). All of the Transmitters are compatible with the Receiver. The Wallplate TX and Decor Wallplate TX must use DXLink power injectors when connecting directly to an HDMI RX; others may cause damage.

Product Notes

The Transmitters and Receiver are designed for transmission of an HDMI signal over twisted pair cable (or a DVI signal via a DVI-to-HDMI cable adapter) up to 328 feet (100 m). Functionality is briefly described below.

Multi-Format TX – The Multi-Format TX receives an HDMI signal or analog video signal (composite, Y/c, Y/Pb/Pr, RGB, RGBS, or RGBHV) and an audio signal from a source device. The audio can be either digital audio embedded with the HDMI signal, digital audio over S/PDIF, or analog stereo audio.

Either analog or digital video is transmitted out of the DXLink output. The active video selection is made using one of two methods: 1) Automatic, which selects digital video as the priority video input or analog video when no digital video is present. 2) Active ICSP command video input selection from a bound NetLinx Central Controller.

Both the video and audio are transported over twisted pair cable to an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution (to an HDMI RX), or directly to an HDMI RX.

The 232 port (RS-232) on the Multi-Format TX supports bidirectional serial data via the twisted pair cable to/from the 232 port on an HDMI RX. The Multi-Format TX also has IR ports.

HDMI TX – The HDMI TX receives an HDMI signal and an audio signal from a source device. The audio can be either digital audio embedded with the HDMI, digital audio over S/PDIF, or analog stereo audio. Both the video and audio are transported over twisted pair cable to an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution (to an HDMI RX), or directly to an HDMI RX. The 232 port (RS-232) on the HDMI TX supports bidirectional serial data via the twisted pair cable to/from the 232 port on an HDMI RX. The HDMI TX also has IR ports.

Wallplate TX and Decor Wallplate TX – These wallplates receive an HDMI signal or analog video signal (composite, Y/c, Y/Pb/Pr, RGB, RGBS, or RGBHV) and an audio signal from a source device. The audio can be either digital audio embedded with the HDMI signal or analog stereo audio.

Either analog or digital video is transmitted out of the DXLink output. The active video selection is made using one of two methods: 1) Automatic, which selects digital video as the priority video input or analog video when no digital video is present. 2) Active ICSP command video input selection from a bound NetLinx Central Controller.

Both the video and audio are transported over twisted pair cable to an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution, or directly to an HDMI RX. Direct connection requires either PDXL-2 (FG1090-170) or PS-POE-AT-TC (FG423-84).

HDMI RX – The HDMI RX receives an HDMI signal with embedded audio over twisted pair cable from a DXLink compatible device (or from a DXLink Transmitter) and sends the signal on to the destination. Audio received on the HDMI RX can also be output on the Stereo Audio Out port if it originated as a 2 channel audio signal. The 232 port (RS-232) on the HDMI RX supports bidirectional serial data via the twisted pair cable to/from the 232 port on the Multi-Format TX or HDMI TX. The HDMI RX features SmartScale® Technology (integrated EDID output scaling) to ensure an appropriate output resolution, plus it supports a Manual (override) option for setting up custom resolutions and a Bypass option. The HDMI RX also has IR ports.

Note: If a DVI-D signal is used (via a DVI-to-HDMI cable adapter), the advanced audio support from HDMI will not be available.

Note: These DXLink products support several different modes which are available for system setup and use. Brief explanations of the modes are provided in the section "Quick Reference Tables for Modes" on page 23 along with page references to complete information.

FIG. 11 DIP switch on Wallplate TX (remove mounting bracket) and on Decor Wallplate TX

For complete information on setting DIP switches (including settings for common scenarios), see the section starting on page 40.

USB Port (Rear) – This port will be supported with a future firmware upgrade.

DXLink Multi-Format TX

FIG. 12 TX USB port = host (top); RX USB port = keyboard/mouse (bottom)

Multi-Format and HDMI Transmitters

The USB-B port on the rear of the Multi-Format TX and HDMI TX can be connected to a PC to support a USB device. This port is considered the Host port, which is used in conjunction with the USB-A port on the rear of the HDMI RX. As the Host port, it is connected to a PC and passes through information via the DXLink connection to the HDMI Receiver.

HDMI Receiver

The USB-A port on the rear of the HDMI Receiver supports pass through information from the USB Host port on the Transmitter to an HID (Human Interface Device), which is most commonly a keyboard or mouse.

HDCP Compliance

If the connected downstream sink is not HDCP compliant, then the HDMI output on the Receiver will not send the signal. This does not affect additional displays the source may be routed to, i.e., HDCP compliant displays will still show content from the source device even when the source device is also routed to non-compliant displays. Non-compliant devices can be easily identified because they display a dark red image or an orange image to indicate the authentication process failed.

IR Control on HDMI TX, Multi-Format TX, and HDMI RX (Optional)

The following two items are required for IR control. In addition, a compatible remote control unit can be used with the system. (The two items listed are not included with the modules.)

- IR03 – External IR Receiver Module (FG-IR03). The IR03 can be connected to the IR RX port on the Multi-Format TX or HDMI TX or to the IR RX port on the HDMI RX, allowing IR signals to be received from a compatible IR remote control. The IR03 allows the Multi-Format TX or HDMI TX to be placed behind the display device if desired.

- CC-NIRC – NetLinx IR Emitter Cable (FG10-000-11). The CC-NIRC can be connected to the IR TX port on the Transmitter or to the IR TX port on the HDMI RX. This allows IR signals to be sent to the source device from the Multi-Format TX or HDMI TX or to the display device from the Receiver.

Quick Reference Tables for Modes

The modes listed in the following three tables are those supported by DXLink Transmitters and Receivers. The Quick Reference Tables are intended to help users navigate the many modes available for system setup and use. For complete information on any of the modes listed, see the relevant sections or chapter referenced at the end of the Description.

Quick Reference Table – Modes for Handling System Architecture
Mode Description
DXLink Modes	DXLink Modes refer to the type of physical components and how they are connected to make up the system. When Transmitters and Receivers are cabled into a system and powered on, they automatically detect the DXLink Mode they are being used in. Endpoint Mode:When the system is setup to use Transmitters and/or Receivers with an Enova DGX Digital Media Switcher or an applicable Enova DVX Solution, the system is in Endpoint Mode (see example on page 34).OrWhen a TX is directly connected to an RX but, in addition, the TX and/or RX is connected to a NetLinx Central Controller via a LAN or directly connected to the Controller, the system is in Endpoint Mode (see example on page 37).Extender Mode:When a TX is directly connected to an RX, the system is in Extender Mode (see example on page 38).For further information, reference #2 Toggle DIP switch settings for DXLink Mode (see page 41) and DXLink System SEND_COMMANDs (see page 98).

Quick Reference Table – Modes for Handling Addressing/Networking

By default, all network connection settings are turned OFF.Static IP Mode:This mode configures the network connection to one stable IP address the device will use continuously.DHCP Mode:This mode configures the network connection to choose a new IP address for each network session.To enable network capability, see “Network Configuration” on page 63.
ID Mode	ID (Identify) Mode refers to the protocol for enabling a user to establish device addresses. This Mode, accessible through NetLinx Studio, places the entire system on hold while it waits for an event from a NetLinx device in the named system (e.g., pressing the ID Pushbutton on the TX or RX). For further information, see “Assign a Device Address (ID Mode)” on page 67.
Ethernet Modes Ethernet	Auto Mode:This mode configures the LAN driver to discover its own settings based on the network it is connected to.Speed/Duplex Mode:This mode configures the LAN driver to calculate its speed as either 10 or 100 and to communicate in either half- or full-duplex.Ethernet Mode discovery and configuration information is available through Telnet commands. For further information, see “Establishing a Terminal Connection Via Telnet” on page 111.
Quick Reference Table – Modes for Handling Addressing/Networking (continued)
Master Connection Modes	Master Connection Modes refer to the modes of communication used for connection to the Master as specified via the SET CONNECTION Telnet command.Auto Mode:This mode utilizes TCP communication. It looks for a matching System Number and attempts to come online with the first Master it sees with that System Number.TCP URL Mode:TCP; the Master is specified via URL.UDP URL Mode:UDP; the Master is specified via URL.NDP Mode (Default):UDP; utilizes the NDP binding process to assign the DXLink Module (the physical device) to a Master (or Virtual Master) via NetLinx Studio. Once bound, communications are conducted via UDP.For further information, see “Master Connection Modes” on page 119.
IRSEND_COMMAND Modes	IR SEND_COMMAND Modes refer to displaying and setting the IR port active system settings as IR, Serial, or Data modes.GET MODE SEND_COMMAND:The GET MODE SEND_COMMAND reveals the active system (IR, Serial, or Data) settings.SET MODE SEND_COMMAND:The SET MODE SEND_COMMAND changes the active system settings.For further information, see “IR SEND_COMMANDs” on page 91.

Quick Reference Table – Modes for Handling Video Processing
Mode Description
Scaling Modes	Scaling Modes refer to how the system alters or maintains a source device's resolution as it is passed along to the destination device. The Scaling Mode can be set on the HDMI RX with the Scaling button (see page 59), or with SEND_COMMANDs (see page 81), or though DGX Configuration Software when scaling is being done via an Enova DXLink Output Board.Auto Mode (Default):• Auto Mode (SmartScale®) allows the destination device to choose the resolution it needs.Manual Mode:• Manual Mode allows the user to configure the resolution the video will display through a destination device.Bypass Mode:• Bypass Mode allows the video signal to display over the destination device without altering the signal's resolution.

Product Overview and Specifications

Installation and Setup

Site Recommendations

When placing the DXLink Transmitters and Receivers in an installation, follow the recommendations and precautions in this section to reduce potential setup and operation hazards.

Environment

☐ Choose a clean, dust free, (preferably) air-conditioned location.
☐ Avoid areas with direct sunlight, heat sources, or high levels of EMI (Electromagnetic Interference).

Multi-Format TX, HDMI TX and HDMI RX Accessibility

Make sure the front of each module is accessible, so that you can monitor the LED indicators. Leaving adequate clearance at the rear will also allow for easier cabling and service.

Power

The power source's electrical outlet should be installed near the module, easily accessible, and properly grounded. Power should come from a building branch circuit. To avoid an overload, note the power consumption rating of all the equipment connected to the circuit breaker before applying power.

General Hazard Precautions

These recommendations address potential hazards that are common to all installations.

Important: DXLink twisted pair cable runs for DXLink equipment should only be run within a common building.

Elevated Operating Temperature

The maximum rated ambient temperature is 104^ (40^) for DXLink Transmitters and Receivers. All equipment should be installed in an environment compatible with the manufacturer's maximum rated ambient temperature. In a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the ambient room temperature.

Caution: To protect the equipment from overheating, do not operate in an area that exceeds 104^ F ( 40^ C) and follow the clearance recommendation below for adequate airflow.

Airflow Restriction

The modules are designed to adequately dissipate the heat they produce under normal operating conditions; however, this design is defeated when high heat producing equipment is placed directly above or below the modules.

Caution: To prevent overheating, avoid placing high heat producing equipment directly above or below the modules. We recommend allowing plenty of clearance above the vent holes on top of the modules. Do not place anything directly on top of the modules that would restrict airflow through the vent holes on top.

Reliable Earthing (Grounding)

Reliable earthing of rack-mounted equipment should be maintained. If not using a direct connection to the branch circuit (e.g., plugging into a power strip), pay particular attention to supply connections (not applicable when power is supplied from an Enova DGX Digital Media Switcher or Enova DVX Solution via a DXLink line). When using DXLink Power from a switcher, we recommend wiring a technical ground for the ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and switcher (see page 45).

Unpacking Tips

Before fully unpacking the Transmitters and Receivers, inspect the shipping box(es) for any signs of damage. If a box is partially crushed or any sides have been broken open, notify the shipping agency immediately and contact your AMX representative (see the warranty at www.amx.com).
☐ Once unpacking is complete, closely check the physical condition of the units.
□ Collect all documentation.

Note: Please save the original shipping container and packing materials. AMX is not responsible for damage caused by insufficient packing during return shipment to the factory. Shipping boxes are available; for details, contact your AMX representative.

Setup Information

Setup Requirements

● A PC with NetLinx Studio (v3.3 or later) installed.
- An understanding of which DXLink Mode the system will be used in (see below and page 38).
- An understanding of the DIP switch settings (see page 41).
- When used with an Enova DGX Digital Media Switcher – The system’s power requirements must be determined (see page 38).
- When used with an Enova DVX Solution – The SEND_COMMANDs for enabling network activity (Ethernet traffic) over the DXLink line must be used (see page 100).

Important: We recommend that DXLink equipment be installed by a technician with knowledge of networks and experience with NetLinx Studio and its Telnet interface. NetLinx experience should include changing device addresses, binding devices, updating firmware, etc.

The remainder of the “Setup Information” section covers information for system setup, power budget planning, network loop concerns, DIP switch settings, mounting options, chassis grounding, cable requirements and recommendations (including RJ-45 pinouts and LED behavior), and audio type precedence.

The specific installation's requirements dictate the system setup, which generally takes one of the following three forms.

• Endpoint Mode (Switcher) – One or more Transmitters and/or Receivers are connected to a switcher* containing a Master (see below).
• Endpoint Mode (Standalone) – A standalone DXLink TX/RX pair are connected directly to each other but, in addition, either the TX or RX is connected to a NetLinx Central Controller via a LAN or directly to the Controller (see page 37).
• Extender Mode (Standalone) – A standalone DXLink TX/RX pair are connected directly to each other as a simple extender solution (see page 38).

* The switcher can be either an Enova DGX Switcher or an applicable Enova DVX Solution (see “Product Compatibility Tables” on page 8).

Endpoint Mode (Switcher): Example of Typical System Setup

The primary function of the Transmitters and Receivers is to work with compatible DXLink equipment as an endpoint solution for transmission of HDMI over twisted pair cable (or DVI-D signals with the use of a DVI-to-HDMI cable adapter, or analog video signals through a Multi-Format TX, Wallplate TX, or Decor Wallplate TX).

The Transmitter receives an HDMI signal and an audio signal from a source device. The audio can be either digital audio embedded with the HDMI signal, digital audio over S/PDIF (S/PDIF is not available on the Wallplate TX or Decor Wallplate TX), or analog stereo audio. Both the video and embedded audio are transmitted over twisted pair cable to the RJ-45 connector on the DXLink Input Board. The HDMI signal is then routed through any (or all) of the connectors on one or more output boards.

When the HDMI signal is routed through a DXLink Output connector to a DXLink HDMI Receiver, the Receiver sends the HDMI signal with embedded audio on to the destination device. The audio can also be output on the Receiver's stereo audio port.

In a system where DXLink Transmitters and Receivers are used in conjunction with a switcher (e.g., the Enova DGX 16), the cable runs from a Transmitter to a DXLink Input Board and from a Receiver to DXLink Output Board can each be up to 328 feet (100 m).

FIG. 13 Endpoint Mode (Switcher) setup with Enova DGX 16

Tip: For systems with special requirements – Before installing in the final location, place the equipment close together, so that the destination monitor and a PC for control can be seen simultaneously if adjustments are necessary. Scaling adjustments can be made using SEND_COMMANDs (see page 79). For Enova DGX Switchers, DGX Configuration Software can also be used to make scaling adjustments via the switcher (see the switcher's "Instruction Manual").

Caution: Be careful not to create a network (Ethernet) loop. To avoid doing so, see page 40.

Custom EDID Settings

- If Transmitters are part of an Enova DGX endpoint system which requires custom EDID settings, see the switcher's Instruction Manual for information on the EDID programming functionality in DGX Configuration Software (available at www.amx.com). SEND COMMANDs can also be used (see page 79).

- If Receivers are part of an Enova DGX endpoint system which requires scaler control and settings, see the switcher's Instruction Manual for information on the scaling functionality in DGX Configuration Software (available at www.amx.com). SEND_COMMANDs can also be used (see page 79).

A Transmitter and Receiver standalone pair can also work together as an extender solution for transmission of HDMI over twisted pair cable up to 328 feet (100 m). The standalone setup supports DVI-D signals with the use of a DVI-to-HDMI cable adapter. A Multi-Format TX and HDMI RX pair can also support an analog video source.

In Extender systems with a Wallplate TX or Decor Wallplate TX, power can be provided to the units via the DXLink line by connecting a DXLink power injector to the Wallplate and using either the desktop power supply or another DXLink power injector with the HDMI RX.

FIG. 16 Extender Mode (Standalone) system

Important Power Considerations for Enova DGX Endpoint Systems

• Local power – Local power (the desktop power supply) always takes precedence over power via the DXLink line from the switcher. However, if a locally powered unit is connected to a switcher and the local power is lost (i.e., unplugged or turned off), the unit will power down and then automatically power back up using power from the switcher via the DXLink connection (increasing the overall power draw on the switcher). When local power is restored, it automatically replaces the power over the DXLink line.

• DXLink power – When modules are being powered by an Enova DGX DXLink board, PDXL-2, or PS-POE-AT-TC (using power via the DXLink line), to maintain the switcher's power redundancy, we recommend that you:

• Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints (modules); see below.

• Do not use the local DC power jack on the module (even if the local power adapter is turned off).

Note: When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground for ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and switcher (see page 45).

Power Budget Planning for System Setup with an Enova DGX

Note: This section does not apply to the Enova DVX Solutions due to their minimal number of DXLink connections.

Before installing an Enova DGX Digital Media Switcher and connecting any required DXLink Transmitters and Receivers, the total power draw for the system should be calculated in order to maintain the redundancy of the power supplies in the enclosure. (Each Enova DGX enclosure ships with two mutually-redundant power supplies.)

Important: If you do not plan to draw power from the Enova DGX enclosure's power supplies, you must power the DXLink Transmitter and Receiver Modules with local power (desktop power supply) or remote power (DXLink power injector), which always overrides power from the switcher. If that power source is turned off, the DXLink Transmitters and Receivers will reboot and then start drawing power from the switcher.

Power Budget Calculation

Calculating the power budget helps determine how many DXLink Transmitters and Receivers can be powered through the Enova DGX Digital Media Switcher while maintaining power redundancy if one of the power supplies should fail. The Enova DGX Configuration Tool is used to determine the switcher's power budget. Simply enter the types of boards and the number of DXLink Transmitters and Receivers to be powered through the switcher, and the calculator shows the resulting power draw. The Enova DGX Configuration Tool is at www.amx.com/enova.

If more DXLink units are required than the switcher can support while maintaining redundancy, any DXLink Modules can be powered using the provided desktop power supplies, PDXL-2 (FG1090-170), or PS-POE-AT-TC (FG423-84).

Important: AMX does not support the use of any power supplies other than the provided ones or power injectors other than the ones approved as they may potentially damage the DXLink equipment.

Foregoing Power Supply Redundancy

Depending on particular Enova DGX input and output board configurations, operating over the redundant power supply level may be necessary on a permanent basis for some installations. While foregoing the benefits associated with a redundant power supply should be understood, operating without redundancy is in no way detrimental to the system, as long as both power supplies are operational. In this case, necessary power will be pulled evenly from both supplies. However, the loss of one power supply will result in the system being non-operational from a normal “non-redundant” system capability perspective.

In the Event of a Power Supply Failure

If an Enova DGX power supply fails, check the following to determine which situation applies:

• Enova DGX 8/16 within its power budget – the system will continue to run; okay to leave it powered until the failed power supply is replaced.
• Enova DGX 8/16 over its power budget – the system will continue to run; however, we do not recommend leaving it powered until the failed power supply is replaced, unless enough DXLink Transmitter or Receiver Modules are removed (or powered locally) to bring the system's power budget within its maximum limit. (Another option is to remove some of the input and/or output boards.)
• Enova DGX 32 within its power budget – the system will continue to run; okay to leave it powered until the failed power supply is replaced.
• Enova DGX 32 over its power budget – the remaining power supply will turn off. If enough DXLink Transmitter or Receiver Modules are removed (or powered locally) to bring the system's power budget within its maximum limit, the system will be able to run until the failed power supply is replaced. (You can also remove some input and/or output boards.)

In all of the situations above, the power supply should be replaced as soon as possible to restore power redundancy to the system or to allow the system to become fully operational again. Unless the Enova DGX Digital Media Switcher has exceeded its power budget, it should operate normally with a failed power supply. For additional information on power supplies and power supply troubleshooting for an Enova DGX Switcher, see the Instruction Manual – Enova DGX 8/16/32 Digital Media Switchers at www.amx.com. For power supply replacement information, contact technical support (see page 104).

Avoiding Network (Ethernet) Loops

Caution: Be careful not to create a network (Ethernet) loop.

Only one connection to a LAN is permitted within a switching system with DXLink support. Network loops must be avoided (see FIG. 17).

Example

In the example in FIG. 17, a network loop was created when the Enova DGX 16 was connected to a LAN and one of its DXLink Transmitters was connected to the same LAN. The DXLink Transmitter must be disconnected from the LAN. The same problem would also occur if an enclosure and one (or more) of its DXLink Receivers were connected to a common LAN. Remember to avoid network loops.

FIG. 17 Avoid network loops

DIP Switch Location

Tip: For easiest access to the DIP switch toggles, we recommend setting them before installation.

DIP switch toggles for enabling/disabling special Receiver/Transmitter functionality are located on the bottom of the Receiver and the Transmitters (FIG. 18), on the rear of the Wallplate TX (left in FIG. 19), and on the front of the Decor Wallplate TX (right in FIG. 19).

Note: DIP switch settings on any of these DXLink products are read only on reboot. After the settings are read, any adjustments of the toggles will not be implemented and will not affect the system.

FIG. 18 DIP switch on bottom of Receiver and Transmitters

FIG. 19 DIP switch on rear of Wallplate TX (remove mounting bracket) and front of the Decor Wallplate TX

Setting DIP Switch #1 to Enable/Disable Access to ICS LAN 10/100 Port

The #1 Toggle is used for enabling/disabling network activity over the physical ICS LAN 10/100 port. It does not affect network activity over DXLink. (For SEND_COMMANDs to disable/enable ICS LAN functionality, see page 98.)

Note: #1 Toggle settings do not apply to Wallplate TX & Decor Wallplate TX – leave #1 Toggle OFF.

Tip: Common setup scenarios and their DIP switch settings are provided in a table on page 43.

#1 Toggle Settings

• OFF (default) – When the #1 Toggle is set to OFF, network activity over the ICS LAN 10/100 port is disabled.
• ON – When the #1 Toggle is set to ON, network activity over the ICS LAN 10/100 port is enabled.

Installation Options

- Option A – For a network connection between a Transmitter and a Receiver where only one of them is connected to a LAN, set the #1 Toggle to ON for the unit that is connected to the network.

Caution: Option A – Do not connect both the Transmitter and the Receiver to a common LAN as a network loop will result. For information on avoiding network loops, see page 40.

- Option B – When a Transmitter or Receiver is connected to a DXLink input or output on an Enova DGX Digital Media Switcher or Enova DVX switcher, the switcher provides a network connection allowing the Transmitter or Receiver to appear in the online tree in NetLinx Studio (#3 Toggle must be set to ON). For connecting the Transmitter or Receiver to other equipment using the ICS LAN 10/100 port, the #1 Toggle must be set to ON.

Caution: Option B – Because the DXLink connection carries network activity passed from the switcher, do not connect the ICS LAN 10/100 port on the Transmitter or Receiver to the same LAN as the switcher because a network loop will result. For information on avoiding network loops, see page 40.

Setting DIP Switch #2 to Set the DXLink Mode

The #2 Toggle can be set to automatically or manually select the DXLink Mode (to either Extender or Endpoint) for a given Transmitter/Receiver Module or pair.

Note: #2 Toggle settings do not apply to Wallplate TX & Decor Wallplate TX – leave #2 Toggle OFF.

Tip: Common setup scenarios and their DIP switch settings are provided in a table on page 43.

#2 Toggle Settings

- OFF (default) – When the #2 Toggle is set to OFF, the Transmitter and Receiver will each auto-discover* what type of DXLink equipment they are connected to and will automatically self-configure to be in one of two DXLink Modes based on the connection:

• Extender Mode – This mode is automatically selected when a TX and RX are connected directly to each other (a standalone pair). The Transmitter and Receiver act like a simple extender, and serial and IR data is passed through them.
• Endpoint Mode – This mode is automatically selected when a module is connected directly to a DXLink port on a switcher. Serial and IR operations are handled by the host providing control of endpoints. The Master's programming specifies where IR and serial commands are sent (this is handled independently from the routing of the video signals).

* Any time the DXLink connection is re-established or power is cycled on a module, the auto-discovery process will take place, as long as the #2 Toggle remains in the OFF position.

- ON – When the #2 Toggle is set to ON, the auto-discover feature is disabled and the module can be manually set to either Endpoint Mode (default) or Extender Mode. In Endpoint Mode, when the module is connected to a switcher or a separate NetLinx Master*, IR and serial operation are only handled via the host.

* When standalone modules need to be controlled by a separate NetLinx Master, then they need to be in Endpoint Mode. Only one must be connected via the ICS LAN 10/100 port to the Master or to a LAN with the Master on it. This requires #1 Toggle to be ON to enable the ICS LAN port. #2 Toggle needs to be ON to place the modules in Endpoint Mode, and #3 Toggle needs to be ON to enable network connectivity.

Note: On either setting, the DXLink Mode may be set via SEND_COMMANDs (see page 98). When #2 Toggle is set to the OFF position, the auto-discovery process will overwrite the DXLink Mode setting. However, when the #2 Toggle is set to the ON position, auto-discovery is disabled and the mode set by SEND_COMMANDs will persist (i.e., the DXLink Mode setting cannot be overwritten).

Setting DIP Switch #3 for Network Connectivity

The #3 Toggle is used for enabling/disabling network connectivity of the DXLink Transmitter or Receiver. If enabled it allows the Transmitter or Receiver to be configured to connect to a NetLinx Central Controller (used for controlling the DXLink unit and allowing Ethernet traffic); see page 42.

Note: Wallplate TX – Before the DIP switch toggles can be set, the mounting bracket must be removed (unscrew the four screws from the bracket and set it aside). Decor Wallplate TX – Set before adding customer provided decor style front cover plate (requires four screws).

Tip: Common setup scenarios and their DIP switch settings are provided in a table on the next page.

#3 Toggle Settings

• OFF (default) – When the #3 Toggle is set to OFF, the Transmitter or Receiver will not try to connect to the network and will not acquire an IP address.
• ON – When the #3 Toggle is set to ON, the Transmitter or Receiver will attempt to connect to the network via DHCP or static IP, depending on how the unit has been set up (see page 59). The Transmitters and Receivers will not display in NetLinx Studio and will not accept commands or queries unless the #3 Toggle is ON.

Note: After the #3 Toggle is set to ON, a network connection is established, and the NetLinx Studio screen is refreshed, Transmitters and Receivers display in the OnLine Tree as Unbound NDP (Network Detect Proxy) Devices. To facilitate IRL and KIT file transfers, they can be bound to the integrated NetLinx Master in a switcher or to another NetLinx Master. A Virtual NetLinx Master can also be used for file transfers.

Scenarios / DIP Switch Settings Table

The following table contains the most common scenarios for setting up Transmitters and Receivers as a standalone pair or with other equipment. Find the scenario in the table that you want to use and then set the Dip switches accordingly. A detailed explanation of functions for each toggle is provided on the two previous pages.

Note: The #1 and #2 Toggles do not apply to the Wallplate TX and Decor Wallplate TX.

Tip: Each toggle's ON position is toward the connectors on the rear of the DXLink Modules or toward the top of the unit for the DXLink Wallplate TX and Decor Wallplate TX (see page 40).

Common Scenarios DIP Switch Toggle Settings
Standalone Setup – TX/RX pair direct connection 1 2 3 4
AV signals only OFF OFF OFF N/A
AV with Ethernet pass through to networked device*	ON OFF	OFF N/A
AV with NetLinx control of TX/RX unit and serial/IR ports**	ON ON	ON N/A
AV with NetLinx control of TX/RX unit and serial/IR ports, plus Ethernet pass through to networked device*	ON ON	ON N/A
Switcher Setup – TX/RX with Enova DVX/DGX Switcher 1 2 3 4
AV signals only OFF OFF OFF N/A
AV with Ethernet pass through to networked device*	ON	N/A OFF	N/A
AV with NetLinx control of TX/RX unit and serial/IR ports	OFF	N/A ON	N/A
AV with NetLinx control of TX/RX unit and serial/IR ports, plus Ethernet pass through to networked device*	ON	N/A ON	N/A

* Connect the ICS LAN 10/100 port of the DXLink unit to the network device (e.g., laptop, IP controlled projector, AMX ICSLan EXB Device). In a standalone setup, connect the ICS LAN 10/100 port of the other DXLink unit to the network.
** In a standalone setup using NetLinx control of the DXLink serial/IR ports, only one of the DXLink units should be connected to the network (the unit with #1 Toggle enabled).

Important: When connecting a Transmitter or a Receiver in a standalone pair setup to a Master (or Virtual Master) for upgrade purposes, #1, #2, and #3 Toggles must be ON.

Mounting Options for Modules (Rack Trays and Mounting Brackets)

Caution: To prevent overheating, avoid placing high heat producing equipment directly above or below the modules. We recommend allowing plenty of clearance above the vent holes on top of the modules. Do not place anything directly on top of the modules that would restrict airflow through the vent holes on top.

The Multi-Format TX, HDMI TX, and HDMI RX are classified as V Style modules, which have optional V Style mounting hardware. These versatile mounting options include rack trays and mounting brackets for desktops, under desks, on walls, and on poles. For details on V Style Mounting Kit options, see www.amx.com.

FIG. 20 V Style mounting hardware

Important: When mounting under a surface, the module should be mounted upright and lowered in the slots to provide an airflow gap between the surface and the vent holes. If not using V Style brackets, be sure to leave a gap between the top of the unit and the surface for heat to escape.

Mounting Options for Wallplates

Wallplate TX – The holes in the Wallplate TX's mounting bracket are designed to accommodate a variety of double-gang back boxes using two or four screws. Two types of screws are provided: standard and metric. Be sure to orient the mounting bracket as shown in FIG. 21.

FIG. 21 Wallplate mounting bracket used with variety of double-gang back boxes

Decor Wallplate TX – The Decor Wallplate TX mounts in a standard US double-gang back box. Standard decor style cover plates are customer provided to allow matching the individual decor of an environment or matching other standard decor covers in a room/area.

Attaching a Ground Wire to DXLink Transmitters/Receivers

Note: Technically this type of grounding is only required when a DXLink Transmitter or Receiver is connected to an ungrounded device, but this added grounding measure can be used at the discretion of the installer.

If the system is experiencing problems with delivery of DXLink signals to/from an Enova DGX Digital Media Switcher or Enova DVX Solution, adding a ground wire from the TX/RX to the switcher may improve performance. The problem is likely caused by the use of a single phase powered system that does not provide an earth ground for a source or destination's chassis and shields. This can inject unnecessary AC voltage on the HDMI cable shield that can lead to DXLink signal integrity issues. To check for indications of this type of power in the system, look for a two pronged plug or a cord that has only two wires.

Items Required

Phillips #1 screwdriver
6 foot ground wire with ring terminal ends (provided)

Note: Currently shipping DXLink Transmitters and Receivers provide a designated ground location on the rear of the chassis for attaching a ground wire. For instructions on attaching a ground wire to DXLink Modules without a designated ground location, see page 142.

Attaching a Ground Wire to a Common Earthed Ground

Connect the running end of the ground wire (fixed end attached to a DXLink Transmitter or Receiver) to a common earthed ground (ideally, referenced to the Enova DGX Switcher or Enova DVX Solution).

Important: If one DXLink Transmitter or Receiver is grounded, any remaining ungrounded units that are connected to the same board on the Enova DGX Switcher must also be grounded.

Attaching Ground Wire to Module

Important: Before attaching the ground wire to the chassis, ensure all connectors are clear.

To attach a ground wire to a module:

1. If powered, power down the DXLink Module.
2. Remove the designated ground screw and washer from the rear of the module.

FIG. 22 Remove designated ground screw and washer

1. Secure the ring terminal of the ground wire against the chassis with the ground screw and washer.

2. Ensure the ground wire is positioned so that it does not interfere with any of the connectors.

FIG. 23 Position ground wire away from connectors

1. Attach the ground wire to a common earthed ground (see "Attaching a Ground Wire to a Common Earthed Ground" on the previous page).
2. Continue the DXLink Module installation process (or reapply power to the module).

Attaching Ground Wire to Wallplate TX or Decor Wallplate TX

The Wallplate TX and Decor Wallplate TX each have a designated ground screw on the rear; look for the grounding symbol. If the DXLink Wallplate does not have a designated screw, use the screw directly above the DXLink (RJ-45) connector on the rear for grounding.

To attach a ground wire to a DXLink Wallplate or Decor Wallplate TX:

1. If powered, power down the unit by removing the DXLink cable from the rear.
2. Remove the ground screw and washer for the applicable unit, as indicated in FIG. 24.

FIG. 24 Wallplate TX and Decor Wallplate TX - Remove ground screw and washer

1. Secure the ring terminal of the ground wire against the chassis with the ground screw and washer.

2. Ensure the ground wire is positioned so that it does not interfere with the DXLink connector.

FIG. 25 Ground wire positioned so it does not interfere with DXLink connector (Wallplate TX shown)

1. Attach the ground wire to a common earthed ground (see page 45).
2. Continue the installation process (or reattach the DXLink cable from the Enova DGX Switcher to the DXLink unit).

Important Twisted Pair Cable Recommendations

The requirements are the same for the twisted pair cable used with the ICS LAN 10/100 (Ethernet) connector and with the DXLink (RJ-45) connector.

• Twisted pair cable is designed to carry Full HD content over 100 meter (328 ft.) cables with control. For complete cable specifications, see page 26.
• In a typical installation, the cables should be stretched to their full length between the Transmitters and Receivers and the enclosure.
• Cable runs with a minimum specification of ANSI/TIE/EIA 568A-5 and ratings of 250 MHz or better may be used with DXLink equipment. However, cable run topology and environmental influences can affect the overall successful distance capabilities of these runs.
• For successful deployments up to 100 meters without consideration to outside variables, AMX recommends the use of shielded category cable (STP) of Cat6A (or better) versions of shielded twisted pair (STP) for DXLink runs.

For more details and helpful cabling information, reference the white paper titled “Cabling for Success with DXLink” available at www.amx.com or contact your AMX representative.

Important: DXLink twisted pair cable runs for DXLink equipment should only be run within a common building.

Twisted Pair Cable Pinouts

The pinout in FIG. 26 is for twisted pair cable that connects to the ICS LAN 10/100 connector or to the DXLink connector on the Transmitters and Receivers. Use either the T568A or T568B pinout specification for termination of the twisted pair cable used between the modules in a standalone setup or between Transmitters and Receivers and an enclosure in a full system.

FIG. 26 Twisted pair cable pinouts for Ethernet connectors

In a typical installation, the cables should be stretched to their full length between Transmitters and Receivers and the enclosure or between modules in a standalone system. Service loops or coils of the cable may reduce the overall cable performance and should be minimized whenever possible.

RJ-45 LEDs

ICS LAN 10/100 Connector LEDs (modules only)

The following information applies to the LEDs on the ICS LAN 10/100 connector on the modules (FIG. 27). Note that #1 Toggle must be set to ON or ICS LAN functionality will not be provided.

Audio Type Precedence

The connectors for bringing audio into the system on the Transmitters are as follows:

• HDMI In connector – Embedded audio signal
• Digital Audio In jack – Digital audio signal (S/PDIF); not available on the Wallplate TX and Decor Wallplate TX
• Stereo Audio In jack – Analog stereo audio signal

The hierarchy for audio type precedence* is listed in the following table for the Transmitters:

Audio Type Precedence on Transmitters
Incoming Signal Audio Type Selected
HDMI w/ embedded digital audio Embedded digital audio
S/PDIF digital audio only (not applicable for Wallplate TX and Decor Wallplate TX)	S/PDIF digital audio
Stereo audio only Analog audio
S/PDIF digital audio and stereo audio (not applicable for Wallplate TX and Decor Wallplate TX)	S/PDIF digital audio
HDMI w/ embedded digital audio and S/PDIF digital audio (not applicable for Wallplate TX and Decor Wallplate TX)	Embedded digital audio
HDMI w/ embedded digital audio and stereo audio Embedded digital audio
HDMI w/ embedded digital audio, S/PDIF digital audio, and stereo audio (not applicable for Wallplate TX and Decor Wallplate TX)	Embedded digital audio

The audio selected by the Transmitters is embedded on the HDMI signal (if not already embedded) and sent to the switcher (or to an HDMI RX in a standalone pair) via the DXLink cable.

* Audio precedence as specified in the table above is applicable when the AUDIN_FORMAT_AUTO command is set to ENABLE; this precedence can be overridden by SEND_COMMANDs (see page 90).

The type of audio coming into the Transmitters, the HDMI RX will take the embedded audio it receives from a Transmitter** and output the following types of audio:

• HDMI Out connector – Embedded digital audio signal
• Stereo Audio Out connector – Analog stereo audio signal

** These exceptions apply: In order for audio to be sent out of the analog stereo audio connector on the HDMI RX, it must have originated or be embedded in the HDMI signal on the Enova DGX Digital Media Switcher, Enova DVX Solution, or Transmitter as a 2 channel signal (either analog stereo or 2 channel PCM). Multi-channel (>2 channel) L-PCM formats will pass incomplete audio (only 2 of the multiple channels will be sent). All other audio formats will be muted at the connector.

Wallplate Transmitters – Attaching Signal/Transport Cables

Important: If network connection is required – before attaching cables, set DIP switch #3 Toggle.

Important: Do not use the RJ-45 connector on rear for connecting to a standard Ethernet Network.

Note: The ID Pushbutton places the module in ID Mode for setting the NetLinx ID (device only) and provides additional functionality, such as placing the device in Static IP Mode or DHCP Mode. For complete information, see page 66.

Multi-Format TX or HDMI TX – Applying Power

Important: If desktop power is used to power the Transmitter, only the provided desktop power supply should be used and it must not be altered in any way. Remote power can only be provided via a switcher or a DXLink power injector. AMX does not support the use of any other power supplies or power injectors as these may potentially damage the DXLink equipment.

Important Power Considerations for Enova DGX Endpoint Systems

• Local power – Local power (desktop power supply) always takes precedence over power via the DXLink line from the switcher. However, if a locally powered module is connected to a switcher and the local power is lost (i.e., unplugged or turned off), the module will power down and then automatically power back up using power from the switcher via the DXLink connection (increasing the overall power draw on the switcher). When local power is restored, it automatically replaces the power over the DXLink line.

• DXLink power – When modules are being powered by an Enova DGX DXLink board or DXLink power injector (using power via the DXLink line), to maintain the switcher's power redundancy, we recommend that you:

• Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints (modules); see page 38.

• Do not use local DC power jack on module (even if local power adapter is turned off).

Note: When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground for the ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and switcher (see page 45).

The following instructions do not apply if you are using power from the switcher via the DXLink line in an endpoint system.

To apply power to the Multi-Format TX or HDMI TX:

1. Plug the cord from the desktop power supply (provided) into the power jack on rear of the module (2.1 mm DC jack for 12 V local power).
2. Plug the desktop power supply into an AC external power source.

The Power LED on the front of the module turns a constant green, which indicates a ready state.

Some of the additional LEDs also turn a constant green. For normal LED display, see table below.

Multi-Format TX and HDMI TX- Indicator LEDs

The LED indicators are listed in the table as they appear on the front of the module from left to right.

Multi-Format TX and HDMI TX LEDs	Normal Display Indicates

Multi-Format TX and HDMI TX–LED Troubleshooting

If indicator LEDs for modules do not respond with a normal display as stated in table on previous page:

• Check all power connections.
• Check the “Detailed NetLinx (Link/Act and Status) LED Behavior” section on page 61.
• Try the suggestions in the “Troubleshooting” chapter (see page 101).

For information on restoring the module's default settings on power up, see page 68.

HDMI RX – Attaching Signal and Control Cables

Important: Before attaching cables, be sure to set DIP switch's toggles if necessary (see page 41).

Important: Do not use the RJ-45 connector labeled "DXLink" for connecting to a standard Ethernet Network.

Note: Power, IR, and RS-232 ports are covered in their own sections.

To attach signal, transport, and control cables to the HDMI RX:

FIG. 32 Attach signal and control cables to HDMI RX

1. DXLink (input) connector – Attach a twisted pair cable from the switcher (or Multi-Format TX or HDMI TX) to the DXLink connector on the HDMI RX.
2. HDMI Out connector – Attach the HDMI cable that goes to the destination device.*
3. ICS LAN 10/100 connector (optional) – Attach a twisted pair cable from this connector to a LAN. (For NetLinx programming information, see page 79.)
4. USB port (optional) – Connect to a hub using a USB-A cable; connect keyboard and mouse to the hub. (This port is for sending keyboard / mouse commands to a PC.) The USB LED on the front monitors this port. (The USB port will be supported in a future firmware upgrade.)
5. Stereo Audio Out connector (optional) – Plug the audio cable (that goes to the audio destination) into the stereo audio jack. For audio precedence information, see page 50. For information on audio SEND_COMMANDs (including enabling the analog audio format), see page 84.

* DVI cable can be used instead (via a DVI-to-HDMI cable adapter); however, the advanced audio support from HDMI will not be available.

Note: The ID Pushbutton places the HDMI RX in ID Mode for setting the NetLinx ID (device only) and provides additional functionality, such as placing the device in Static IP Mode or DHCP Mode. For information, see page 66.

Tip: If scaling adjustments are necessary, use SEND_COMMANDs (see page 79). If connected to an Enova DGX output, use DGX Configuration Software via the switcher for scaling.

HDMI RX – Applying Power

Important: If desktop power is used to power the Receiver, only the provided desktop power supply should be used and it must not be altered in any way. Remote power can only be provided via the switcher, PDXL-2 (FG1090-170), or PS-POE-AT-TC (FG423-84).

Important: The “Important Power Considerations for Enova DGX Endpoint Systems” also apply to the HDMI RX (see page 54).

To apply power to the HDMI RX:

1. Plug the cord from the desktop power supply (provided) into the power jack on rear of the HDMI RX (2.1 mm DC jack for 12 V local power).

2. Plug the desktop power supply into an AC external power source.

The Power LED on the front of the HDMI RX illuminates a constant green, which indicates a ready state. Some of the additional LEDs will also turn a turn a constant green. For normal LED display, see the table below.

Important: If any HDMI Receivers are being powered through an Enova DGX, we recommend determining the power budget to maintain power redundancy for the system (see page 38).

HDMI RX - Indicator LEDs

The LED indicators are listed in the table as they appear on the front of the RX from left to right.

HDMI RX LED	Normal Display Indicates
Power Green Power is applied to the Receiver
Video Green A video signal is present through the Receiver
Audio Green An embedded audio signal is present through the Receiver
Scaling:– Bypass– Auto– Manual	One LED is greenThe other two are off	Receiver is in one of the three modes for scaling• At initial power up, the Receiver defaults to the Auto scaling option*• Press the Scaling button to turn on the Bypass option or the Manual option
IR TX Red IR TX active communication
IR RX Yellow IR RX active communication
Serial TX Red Serial TX active communication

* When the output cable is disconnected from the HDMI RX or if no EDID can be found on the destination device, the last used Scaling Mode LED will be ON. In either case, the HDMI RX will continue to hold its output resolution to the last known preferred resolution until a power cycle or reconnection of a sink with a valid EDID. On power up without a valid EDID, the default preferred output resolution presented will be 1280x1024 @ 60 Hz until a different EDID is detected.

Receiver – LED Troubleshooting

If the indicator LEDs for the modules do not respond with a normal display as stated in the table above:

☐ Check all power connections.
☐ Check the “Detailed NetLinx (Link/Act and Status) LED Behavior” section on page 61.
☐ Try the suggestions in the “Troubleshooting” chapter (see page 101).

For information on restoring the module's default settings on power up, see page 68.

Serial Data Transfer and IR Flow Control

The illustration in FIG. 33 shows the bidirectional serial data transfer and IR flow control when DXLink Modules are used in Endpoint Mode with an Enova Digital Media Switcher. The switcher has an integrated NetLinx Central Control Processor which provides native AMX control at each remote location fed by a DXLink Transmitter or Receiver. Control is sent over twisted pair cable (via the DXLink ports). This also holds true when Enova DVX Solutions are used.

FIG. 33 Serial data transfer and IR flow control

Optional: Multi-Format TX, HDMI TX, and HDMI RX – Wiring for Serial Data Transfer

The RS-232 (serial) ports are the 3-position screw terminal blocks on the rear of the modules to the right of the ICS LAN 10/100 connector. Wire these ports to supply serial data along with the associated video and audio signals from a source device (over the twisted pair cable between the Multi-Format TX or HDMI TX and the HDMI RX) to a destination device or vise versa from the HDMI RX to the Multi-Format TX or HDMI TX. In addition to being directly connected to a device, this port can be connected as an independent native NetLinx control port from a networked NetLinx Central Controller.

Important: For serial strings to pass through a standalone TX and RX pair (in Extender Mode) without a NetLinx Master acting as the host, DIP switch #2 Toggle must be set to OFF.

The RS-232 port labels are relative to the data flow. On the Multi-Format TX or HDMI TX, data enters the system at the RX label and leaves the system at the TX label on the Receiver (FIG. 34). The flow is reversed from the Receiver to the Transmitter.

Note: On both modules, the RS-232 connector pinout is "TX - RX - Ground."

To wire the RS-232 (serial) connectors on the modules for data transfer:

1. Wire the RS-232 connectors on the modules according to the pinout directly above the connector.

FIG. 34 Wire RS-232 ports for serial data transfer

1. Use the command RXON to enable this port on the Transmitter and the Receiver. (For complete Serial SEND_COMMAND programming information, see page 95.)

Serial Control – Endpoint Mode and SEND\_COMMANDs

In Endpoint Mode (modules are connected to a switcher), serial operations are handled by the host providing control of the endpoints. The Master's programming specifies where the serial commands are sent (this is handled independently from the routing of the video signals). For additional information on Endpoint Mode, see page 41. For Serial SEND_COMMANDs, see page 95.

Optional: Multi-Format TX, HDMI TX, and HDMI RX – IR Control

For additional information on the IR03 and CC-NIRC, which are required for IR control, see page 22. (The IR03 and CC-NIRC are not included with the modules.) A compatible remote control unit can also be used with the system. In addition to being directly connected to a device, this port can be connected as an independent native NetLinx control port from a networked NetLinx Central Controller.

Important: When a Transmitter and Receiver are used as a standalone pair, the IR control feature uses a direct pass through in Extender Mode (the #2 Toggle must be set to OFF). When a Transmitter and Receiver are used with a switcher, the integrated Master handles the SEND_COMMANDs (the #2 Toggle on the DIP switch must be set to ON, which places the DXLink Mode in Endpoint for use with the switcher).

The IR Receiver is connected to the IR RX port on the Transmitter, and the IR Emitter is connected to the IR TX port on the Receiver, or the connections can be reversed.

FIG. 36 IR Emitter cable (FG10-000-11)

To connect an IR Emitter to a module:

1. Connect the Phoenix connector on the CC-NIRC NetLinx IR Emitter cable (FG10-000-11) to the IR TX port on the module.
2. Run the other end of the IR Emitter cable to the display device and locate the IR window.
3. Attach the IR Emitter bud over the device's IR sensor by removing the cover on the reverse side of the Emitter and sticking the bud directly over the IR window.

Important: For systems that include a switcher – when installation of the IR Receiver and IR Emitter is complete, load the appropriate driver (for instructions, see page 73) and program the IR remote according to the product's documentation.

IR Control – Endpoint Mode and SEND\_COMMANDs

In Endpoint Mode (modules are connected to a switcher), IR operations are handled by the host providing control of the endpoints. The Master's programming specifies where the IR commands are sent (this is handled independently from the routing of the video signals). For additional information on Endpoint Mode, see page 41. For IR SEND_COMMANDs, see page 91.

ID Pushbutton Functions

The ID Pushbutton is located on the right front of the modules, on the left edge of the Wallplate TX, and on the front of the Decor Wallplate TX.

The ID Pushbutton can be used to perform four types of initial configuration settings:

• Toggle between DHCP and static IP addressing
• Assign a device address
• Reset the factory default settings
• Restore the factory firmware image

The functions performed depend on when and for how long the ID Pushbutton is pressed and held. For complete ID Pushbutton information, see page 66.

Note: ID Pushbutton functions can also be implemented using Telnet commands (see page 111).

HDMI RX Scaling Button and Scaling Modes

The Scaling button is located on the front of the HDMI Receiver Module. Pressing the Scaling button cycles the module through the three scaling options: Bypass, Auto, and Manual.

• Bypass Mode – allows the video signal to display over the destination device without altering the signal's resolution.
• Auto Mode (default) – allows the destination device to choose the resolution it needs (this mode is AMX's SmartScale ^® Technology in action).
• Manual Mode – allows the user to configure the resolution that the video will display through a destination device.

Selecting a Scaling Mode results in the module maintaining or altering the source device's resolution as it is passed along to the destination device.

The Scaling Mode can be set on the HDMI RX with the Scaling button (see instructions below), with DGX Configuration Software, or with SEND_COMMANDs (see page 81).

To set the scaling option (mode):

1. Press the Scaling button on the HDMI RX once or twice until the LED for the desired scaling option illuminates solid green.

Bypass Mode

Bypass Mode allows the video signal to display over the destination device without altering the signal's resolution.

Note: Interlaced and progressive video are supported into the Transmitters; progressive is only supported out of the Receiver unless it is in the Bypass mode, which is non-scaling.

Auto Mode

At initial power up, the HDMI RX defaults to the Auto scaling option.

Note: When the output cable is disconnected from the HDMI RX or if no EDID can be found on the destination device, the last used Scaling Mode LED will be ON. In either case, the HDMI RX will continue to hold its output resolution to the last known preferred resolution until a power cycle or reconnection of a sink with a valid EDID. On power up without a valid EDID, the default preferred output resolution presented will be 1280x1024 @ 60 Hz until a different EDID is detected.

Manual Mode

Manual Mode allows the user to configure the resolution that the video will display through a destination device. Manual Mode defaults to 1280x1024p @ 60 Hz. This default resolution can be changed in two ways:

• Use the SEND_COMMAND VIDOUT_RES_REF to set the resolution and refresh rate (for details, see page 81).
• When used as a direct output of an Enova DGX DXLink Output Board, use DGX Configuration Software to set and persist the Manual scaling resolution for the connector on the DXLink Output Board; the DXLink Output Board sends the scaling resolution data to the HDMI RX.

Note: The scaling mode (and the aspect ratio) can also be set on the DXLink Output Board using DGX Configuration Software. The data is persisted on the board and sent to the HDMI RX.

Persistence of Scaling Options

The HDMI RX defaults to “Auto” when power is cycled. The scaling option can be persisted using one of the three following methods:

● Using the Scaling button (see instructions below).
- Using the SEND_COMMAND: PERSISTAV (for details, see page 98).
- Using DGX Configuration Software to set and persist the scaling option for the connector on the DXLink Output Board on the Enova DGX Digital Media Switcher; the DXLink Output Board sends the scaling option data to the HDMI RX.

Using the Scaling Button to Persist a Scaling Option

The factory default is for the HDMI RX to revert to the Auto option if power is cycled. If you want the unit to remain in either Manual or Bypass Mode when power is cycled, use the following instructions.

To persist a scaling option on power cycle:

1. Press and release the Scaling button until the LEDs cycle to the option immediately before the one you want to persist.
2. Press and hold the Scaling button about 5 seconds until the desired LED blinks green (indicating that option will persist on power cycle), then release.

Detailed NetLinx (Link/Act and Status) LED Behavior

The tables below provide detailed descriptions of all blink patterns for the NetLinx Link/Act and Status LEDs on the front of the Transmitter and Receiver Modules.

Note: The term “light show” refers to the back-and-forth scanning pattern of the LEDs associated with the LEDs on the modules.

Module Operational State as Indicated by LEDs

To determine the operational state (normal boot) of a module by its LEDs, check both the Link/Act and Status LED columns.

NetLinx LED Behavior and Operational State
Link/Act LED Status LED	Module Operational State
ON if connected to a system with an integrated Master. Blink OFF with data.	Follow Master's instruction for Blink Message if online with Master, otherwise ON.	Normal Online with Master (rest)
OFF ON Normal Boot (DHCP found)		Note: This state continues from the time an IP address is obtained until the device is online with the Master.
Fast blink, then normal operation.	ON Normal Boot (DHCP, no server)	Note: This state continues until a valid IP address is obtained.
OFF during light show, then normal operation (OFF until connected to Master).	Fast blink (continues only during light show), then ON until first blink from Master.	Normal Boot (Static IP)Note: This state continues until the device finishes its light show.

ID Pushbutton Boot State and LED Behavior

To monitor the ID Pushbutton boot state of a module by its LEDs, check both the Link/Act and Status LED columns.

DXLink TX/RX in a Multiple-Stage Switching System

When switching systems with DXLink Technology support (e.g., an Enova DGX Digital Media Switcher and an Enova DVX-3155HD) are connected via their DXLink ports, DXLink Transmitters and Receivers can be used to extend the video and audio transport.

Important: This section does not refer to the linking of enclosures from CPU to CPU, which is not supported in the Enova DGX Digital Media Switcher or the Enova DVX Solutions.

In an installation with DXLink equipment in a multiple-stage switching system, the following apply:

• Network loops must be avoided (see page 40). The DXLink line's Ethernet functionality is disabled between the enclosures; therefore, no IR, serial, or Ethernet communication can be passed between them.
• When two switching systems with DXLink support are connected via their DXLink ports, only video and audio will be passed through the DXLink connection.
• When a DXLink input or output on one switching system determines that it is connected to a DXLink input or output on another switching system, the DXLink port will automatically disable all Ethernet, power, and control on that connection port so that the only things passed down the DXLink line are the video and audio signals.
• When connecting switching systems via DXLink ports, AMX recommends no more than three switcher throughputs (see the “Example” below).

Example

This example shows how DXLink Transmitters and Receivers can be used in a system where switchers are connected via their DXLink ports.

The signal path through three switchers could be: source device → DXLink Transmitter → Enova DVX-3155HD, DXLink input (out a DXLink output) → Enova DGX 32, DXLink input (out a DXLink output) → Enova DGX 16, DXLink input (out a DXLink output) → DXLink Receiver → display device as an HDMI signal.

Network Configuration

Overview

DXLink Modules support two IP Addressing Modes: Static IP and DHCP (with link-local fallback*).

To avoid having a large system consume numerous IP addresses, the Transmitter and Receiver default to disabling the network connection functionality. Therefore, the #3 Toggle must be set to ON before the Transmitter or Receiver can establish a network connection (see page 42).

When #3 Toggle is ON, the DXLink Modules are automatically placed in DHCP Mode, but they can be configured for either of the IP Addressing Modes via two methods:

● The front-panel ID Pushbutton (see page 66)
- Telnet commands (see page 111)

* "Link-local fallback" is a method by which an IP host, as a fallback from DHCP, can derive a local network-unique IP address by negotiating with the other IP hosts on the same network.

Link-local can also be used in its own right as the primary method of IP address allocation. For details, see “DHCP Mode” below.

Static IP Mode - Default Parameters

Important: Static IP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 42). The #3 Toggle must be ON before the device is accessible via SEND_COMMANDs.

Default Parameters For Static IP Mode
Address 192.168.1.2
Netmask 255.255.255	0
Gateway 192.168.1.1
DNS1 192.168.1.1
DNS2 192.168.1.1
DNS3 192.168.1.1

DHCP Mode

Important: DHCP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 42). The #3 Toggle must be ON before the device is accessible via SEND_COMMANDs.

DHCP Mode requires a connection to a network with a DHCP server located on it. This connection can be either indirect or direct.

- Indirect connection – In the case of an Enova DGX Digital Media Switcher or an Enova DVX Solution (Endpoint Mode) that is connected to a DHCP server device, the DHCP connection can be propagated through the system's DXLink layer. First you must complete the following:

- Set the #3 Toggle to ON to enable the network connectivity.

- Direct connection – In the case of a standalone pair (Extender Mode), to place the DXLink Modules in DHCP Mode you must complete the following:

• Set the #1 Toggle to ON to enable access to the physical ICS LAN 10/100 port.
• Set the #3 Toggle to ON to enable network connectivity (DHCP).
• Connect the ICS LAN 10/100 port to a network where a DHCP server is located.

When in DHCP Mode (the default setting), the module will attempt to get a DHCP lease (consisting of an IP address, gateway, and other network parameters). Should the attempt fail, the module will then configure itself for a link-local address.

• DXLink Modules utilize a modified link-local addressing procedure. The first address to be tried is a known address in the link-local space: 169.254.2.2. That address will be probed, and if unclaimed will be used by the DXLink Module.
• If 169.254.2.2 is already claimed, the DXLink Module will choose a random address within the 169.252.x.x link-local address space (again probing to ensure that it is unclaimed).

Once the module is operating with a link-local address, it will periodically re-try DHCP and re-assign the IP to a valid DHCP grant if successful.

At any time, if the module determines that its IP address has changed, it will disconnect from the Master (if necessary, depending on the connection state) and then reconnect to the Master.

TCP/IP Address Configuration

DXLink Modules support IPV4 network addresses, gateway addresses, DNS server addresses, and network names. They also support NDP (NetLinx Discovery Protocol) capabilities as well as IP discovery via NetLinx Studio.

Note: NDP is a device discovery method used by NetLinx Masters. With NDP Beacon enabled, the Master will transmit NDP Beacons for AMX's proprietary device discovery.

Telnet IP Configuration Commands

The SET IP and GET IP Telnet commands listed in the tables in Appendix B (which start on page 112) can be sent directly to the device via a Telnet terminal session. These commands can be used for initial network configuration of the DXLink Modules.

• The default Telnet port is 23.
- Telnet is enabled by default.
- A value of 0 disables the telnet server.

For details, see “Appendix B – Telnet (Terminal) Commands” on page 111. The appendix also includes a section on “Master Connection Modes” on page 119.

Using the ID Pushbutton

The ID Pushbutton is located on the right front of the modules, on the left edge of the Wallplate TX, and on the front of the Decor Wallplate TX.

FIG. 37 ID Pushbutton on module (HDMI TX shown)

The ID Pushbutton can be used to perform four types of initial configuration settings:

• Toggle between DHCP and static IP addressing (see below)
• Assign a device address (page 67)
• Reset the unit to its factory default settings, which affects the parameters but not the firmware version (see page 68)
• Restore the unit to its factory firmware image, which affects both the firmware version and the parameters (see page 69)

The functions performed depend on when and for how long the ID Pushbutton is pressed and held. ID Pushbutton functions can also be implemented using Telnet commands (see page 111).

Tip: To monitor the ID Pushbutton boot state of a module by its NetLinx LED behavior, see page 71.

Toggling Between IP Addressing Modes: DHCP and Static IP

DXLink Transmitters and Receivers support both DHCP and static IP addresses. When the #3 Toggle is ON (see page 42), the modules automatically use DHCP with link-local fallback. However, you can use a static IP address which can be set via a Telnet command (SET IP), or you can use the factory default static IP address. The default static IP address can be recalled at any time by resetting the unit to its factory default configuration (see page 68). The default dynamic (DHCP) address is 169.254.2.2.

The ID Pushbutton can be used to toggle between the DHCP and Static IP Modes.

To toggle between DHCP and Static IP Modes:

1. Once the module has booted up, press and hold the ID Pushbutton until the Control/NetLinx LEDs toggle back and forth in unison approximately 10 times.

2. Release when it starts to blink faster.

- When the Pushbutton is released, the module toggles either from static to dynamic (DIICP) IP addressing or vice versa and remains in that mode until the ID Pushbutton is used to set it again or a factory reset is performed.

- The module automatically reboots to complete the process.

Assign a Device Address (ID Mode)

The ID Pushbutton can be used in conjunction with the ID (Identify) Mode feature in NetLinx Studio. A momentary press of the ID Pushbutton assigns a device address to the Transmitter or Receiver (which must be bound to the Master). The device must first be placed in ID Mode in NetLinx Studio or the momentary press will be ignored.

Note: The latest version of NetLinx Studio is available to download and install from www.amx.com. Refer to the NetLinx Studio online help for instructions on using the application.

To set the device address on a Transmitter or Receiver:

1. Check to be sure #3 Toggle on the bottom of the Transmitter or Receiver is set to ON.
2. In NetLinx Studio's OnLine Tree, select the Master to which the Transmitter or Receiver is bound.
3. From the Diagnostic menu, select Device Addressing. The Device Addressing dialog box opens.

1. In the ID Mode section, enter the Device and System numbers that you want assigned to the device in the appropriate text boxes.
2. Click Start Identify Mode to place the named system in ID Mode.

The button changes to "Cancel Identify Mode" (click to cancel ID Mode).

The text box below the button displays a "Waiting...Press Cancel to Quit" message.

Note: When in ID Mode, the entire system is put on hold while it waits for an event from any NetLinx device in the named system (e.g., pressing the ID Pushbutton on the Receiver). The device that generates the first event is the device that will be "identified."

1. Briefly press and release the ID Pushbutton on the Transmitter or Receiver.

The Transmitter or Receiver will exhibit the following behavior:

• Respond with an ID Mode address response.
  • Report its old address offline.
  • Report its new address online.

The OnLine Tree will refresh to display the new device address for the Transmitter or Receiver.

Note: NetLinx Studio (v3.3 or higher) provides the ability to auto-increment IP Addresses and Hostnames as well as Device and System Numbers. Refer to the NetLinx Studio online help for details.

Reset the Factory Default Settings

During power up – if the ID Pushbutton is held until the Control/NetLinx LEDs toggle back and forth in unison approximately 10 times, then released when the faster blinking starts, the Transmitter or Receiver will reset to its factory default settings, which affect the parameters but not the firmware version.

Factory Parameters\*

• Default static IP address of 192.168.1.2
• Default dynamic (DHCP) address of 169.254.2.2
• Default device number of 0
• NDP mode (see page 119)
• Unbound state
• No IRL files

* For a complete list of factory parameters, see the table on page 65.

Instructions for the modules are given first followed by the instructions for the Wallplate TX and the Decor Wallplate TX, which receive power over DXLink from the switcher.

Important: If a Transmitter or Receiver Module is receiving power from a switcher, disconnect the DXLink connector on the module and reattach to apply power.

To reset a Transmitter or Receiver Module to its factory default settings:

1. Press and hold the ID Pushbutton while plugging in the power connector. Start counting when the NetLinx LEDs begin to flash in unison, not when the power connector is inserted.

2. Once the Transmitter or Receiver Module has started booting up, both NetLinx LEDs flash in unison at the rate of once per second.
   ● After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.

Note: A press-and-hold of the ID Pushbutton at power up will prevent the Transmitter or Receiver from attempting to come online until the ID Pushbutton is released. The Transmitter or Receiver will only attempt to come online if you release the Pushbutton prior to the faster blink rate.

1. At the point that the blink rate increases, release the ID Pushbutton.
2. The Transmitter or Receiver will automatically reboot to complete the process.

To reset Wallplate TX or Decor Wallplate TX to its factory default settings:

The ID Pushbutton and the Reset button are located on the left edge of the Wallplate TX and on the front of the Decor Wallplate TX.

1. Press and hold the ID Pushbutton. While the ID Pushbutton is down, press and release the Reset button. Start counting when the NetLinx LEDs begin to flash in unison, not when the Reset button is released.

2. Once the unit has started booting up, both NetLinx LEDs (on bottom edge) flash in unison at the rate of once per second.
   ● After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.

Note: A press-and-hold of the ID Pushbutton at boot will prevent the unit from attempting to come online until the ID Pushbutton is released. The unit will only attempt to come online if you release the Pushbutton prior to the faster blink rate.

1. At the point that the blink rate increases, release the ID Pushbutton.

2. The unit will automatically reboot to complete the process.

Restore the Factory Firmware Image and Factory Default Parameters

During power up – if the ID Pushbutton is held until the Control/NetLinx LEDs toggle back and forth in unison approximately 30 times (10 slow, 20 fast) and then released when they go solid, the module's factory firmware image will be restored. This procedure affects both the firmware version and the parameters.

Instructions for the modules are given first followed by the instructions for the Wallplate TX and the Decor Wallplate TX, which receive power over DXLink from the switcher, PDXL-2 (FG1090-170), or PS-POE-AT-TC (FG423-84).

Important: If a Transmitter or Receiver Module is receiving power from a switcher, on the module disconnect the RJ-45 cable from the DXLink connector before starting the instructions below.

To restore the Transmitter or Receiver Module to its factory default firmware image:

1. Press and hold the ID Pushbutton while plugging in the power connector (if the power source is a switcher, plug in the RJ-45 connector into the DXLink port instead). Start counting when the NetLinx LEDs begin to flash in unison, not when the power connector is inserted.

2. After the LEDs complete the following sequence, release the ID Pushbutton:

3. Once the Transmitter or Receiver has started booting up, all LEDs flash in unison at the rate of once per second.
   ● After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.
   ● After 10 seconds of flashing at the increased rate, all LEDs go to solid on.

4. Upon release of the ID Pushbutton, the Transmitter or Receiver executes the following actions:

a. Restores itself to its factory firmware image.
b. Resets to factory default parameters*:

• Deletes all IRL files stored on the device.
• Resets to the default static IP address of 192.168.1.2 and default DHCP address of 169.254.2.2.
• Resets to the default device number of 0 (when bound to a Master, it will receive a dynamic device number from the Master).
• Resets to NDP mode and being unbound.

* For a complete list of factory parameters, see the table on page 65.

1. Once all actions in Step 3 are completed, the LEDs all turn off, indicating the Transmitter or Receiver is ready to reboot.

IRL File Transfers

Overview

The NetLinx Studio software application (available for free download from www.amx.com) provides the ability to transfer IR Library files to NetLinx devices such as DXLink Transmitters and Receivers.

Endpoint System (with a Switcher)

When a Transmitter and/or a Receiver are being used in conjunction with a switcher as an endpoint system, the switcher's integrated Master is used for the IRL file transfer. FIG. 38 shows a Transmitter and a Receiver bound to the integrated Master in an Enova DGX 32 in NetLinx Studio's OnLine Tree. Follow the instructions on the top of page 74 to prepare an endpoint system for IRL file transfer and the instructions on page 76 for the actual transfer.

FIG. 38 NetLinx Studio – Integrated Master, Enova DGX 32, DXLink Transmitter, and DXLink Receiver

Extender System (Standalone)

When a standalone Transmitter and Receiver Module pair are being used as a extender system, the IRL file transfer can be done one of two ways:

• The module can be bound to any Master on the network and then unbound when the file transfer procedure is complete.
• If a Master is not present on the network, a Virtual NetLinx Master can be set up using a PC (see page 121).

Follow the instructions on page 75 to prepare an extender system for IRL file transfer and the instructions on page 76 for the actual transfer.

Preparing for IRL File Transfers in an Endpoint System

To prepare for IRL file transfers in an endpoint system:

1. Check to be sure #3 Toggle on the bottom of the Transmitter or Receiver is set to ON.

2. Verify that you have the latest version of NetLinx Studio on your PC.

If the version is not the latest:

- Use the Web Update option in NetLinx Studio's Help menu to obtain the latest version.

Or

- Go to www.amx.com and login as a Dealer to download the latest version.

1. Download the applicable IRL file from www.amx.com (Partners / Search Devices) to your PC.

2. Verify the following:

a. Verify that an Ethernet/RJ-45 cable is connected from the switcher's integrated Master to the network (e.g., from the LAN 100/1000 port on an Enova DGX 32 to a LAN).

b. Verify that the target Transmitter or Receiver is connected via its DXLink connector to a DXLink Input or Output Board (respectively) on the switcher.

c. Verify that the switcher is powered on.

1. Launch NetLinx Studio and open the OnLine Tree.

2. Bind the target Transmitter or Receiver to the integrated Master:

a. Select and right-click the TX or RX in the Online Tree.

b. From the context sensitive menu, select Network Bind/Unbind Device.

c. Verify that the check box is selected. If not selected, select it now.

Aspect Ratio Options

Stretch (to fit) – This option (default) scales the video to full screen size in both horizontal and vertical directions regardless of the input aspect ratio. No data is cropped. However, the image may be distorted as needed to fill the screen. When Stretch is selected, black bars are not added by the scaler. However, if an image has originated from a source device with either horizontal or vertical black bars (e.g., letter box from a movie), the black bars will be considered as active video and will be included in the stretched video.

Maintain (aspect ratio) – This option maintains the incoming video's aspect ratio, but will scale the image until the display fills either horizontal or vertical direction first. If the vertical direction is filled first, then the video will have pillar box black bars on the sides of the display. If the horizontal direction is filled first, then the video will have letter box black bars on the top and bottom of the display.

Zoom - This option maintains the input aspect ratio while zooming the image to fill the screen in all directions. Image data may be lost on the top and bottom or to the left and right of the displayed image.

Anamorphic - This option is used with anamorphic formatted video sources so that images appear correctly on the display.

Troubleshooting

Overview

The troubleshooting suggestions/strategies provided apply to the Transmitters and the Receiver, unless otherwise noted.

Four potential types of issues are covered in this chapter:

• Basic troubleshooting
  • Determining HDCP compliance
• Power
• DXLink connections
• Network setup

This chapter also provides technical support contact information on page 104.

Basic Troubleshooting

We suggest using the following general list to rule out basic troubleshooting issues.

☐ Check the power indicator LEDs on all of the equipment. If any are not illuminated, see the "Power Issues" section on the next page.
☐ Check all link and signal connections to make sure everything is physically set up correctly.
☐ Isolate source and destination equipment and cable problems by cabling direct without the DXLink units.
□ Check the DIP switch's toggle settings (see page 40).
☐ SEND_COMMANDs – double-check the command and the port number specified and re-send the command (see page 79).
☐ If any changes have been made, try resetting the unit to the factory defaults (see page 68).

Additional Resources for Troubleshooting Endpoint Systems

Enova DGX Digital Media Switchers

When the DXLink units are used in conjunction with an Enova DGX Switcher, we suggest checking the troubleshooting information in that product's Instruction Manual.

Enova DVX Solutions

When DXLink units are used in conjunction with an Enova DVX Solution, we suggest: pressing the Status button on the front panel and using the UP and DOWN navigational buttons to scroll through the menu options to Diagnostic Codes (the codes can be helpful for technical support if a call is necessary).

Determining HDCP Compliance

A dark red or an orange screen on an output display is the visual cue from DXLink devices that the display device cannot display the HDCP compliant signal from the source.

Power Issues

Upon power up, the Power indicator LED on the front of the DXLink units illuminates solid green. If the Power LEDs on any of the system's equipment are not illuminated:

☐ Check the power cords or DXLink (RJ-45) connection if using power over the DXLink line.
☐ Check the power connections on the switcher if using power over the DXLink line.
☐ Check the power connections on the source and destination devices.

DXLink Power Delivery Issues

Unexpected power interruptions of DXLink Transmitters and Receivers may be caused by the Enova DGX Digital Media Switcher being powered by single phase power. Connecting a ground wire to the DXLink unit's chassis and a common earthed ground (ideally, referenced to the switcher) will stop power interruptions. For information on when and how to attach ground wires to DXLink units, see page 45.

Important Power Considerations for Enova DGX Endpoint Systems

• Local power – Local power (the desktop power supply) always takes precedence over power via the DXLink line from the switcher. However, if a locally powered module is connected to a switcher and the local power is lost (i.e., unplugged or turned off), the module will power down and then automatically power back up using power from the switcher via the DXLink connection (increasing the overall power draw on the switcher). When local power is restored, it automatically replaces the power over the DXLink line.
• DXLink power – When Transmitters/Receivers are being powered by an Enova DGX DXLink board or DXLink power injector (using power via the DXLink line), to maintain the switcher's power redundancy, we recommend that you:
• Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints (Transmitters/Receivers); see page 54.
• Do not use the local DC power jack on the module (even if the local power adapter is turned off).

Power Issues with Enova DGX Endpoint Systems

In an Enova DGX Endpoint System when multiple endpoints (Transmitters/Receivers) cycle their power and the DXLink connection fails, check the following:

☐ Check to be sure that Transmitters/Receivers being powered by the local DC jack have power. (Local power always takes precedence.)

☐ Check to be sure that Transmitters/Receivers intended to be powered via the DXLink line do not have a DC jack plugged in (even if the local power adapter is turned off). This can cause inadvertent ground loops that can negatively affect DXLink power sensing circuits.

DXLink Connection Issues

One method for determining DXLink connection issues is to compare the pattern of the green and yellow DXLink LEDs on the Transmitter or Receiver against the tables below and then check the suggested items in the Troubleshooting column in the second table.

DXLink LED Patterns When Connection is Working as Expected

Check the status of the green and yellow DXLink LEDs (on rear of the modules – on lower edge of the Wallplate TX, or on the front of the Decor Wallplate TX – under customer provided standard decor style cover plate) against the following table to determine the status of the video signal over the DXLink line. All of the green / yellow patterns in this table indicate that the unit is working as expected given its current connections. If the LED pattern does not correspond to any of the green / yellow patterns in this table, check the table below.

LED Patterns - Working as Expected
Green Yellow LED Pattern		Description
Solid green	Solid yellow	The DXLink link is established and the video stream is passing HDCP protected content.
Solid green	Flashing yellow	The DXLink link is established and the video stream is passing unprotected content.
Solid green Off The DXLink links established but no video content is being passed.
Off Off The DXLink link is not established and the accompanying DXLink unit is not powered on or is not connected.

DXLink LED Patterns When Connection is Failing

If the green / yellow DXLink LEDs on a unit do not have one of the normal patterns as stated in the table above, check the patterns in the table below and then check the items listed in the corresponding Troubleshooting column.

LED Patterns - Connection Failing
Green Yellow LED Pattern Description Problem Symptoms Troubleshooting
Solid green Sporadic flashing yellow	Poor DXLink signal quality	Video drops occasionally	Check for:• Cable installation problems• Alien crosstalk• If possible, identify the hostile cable
Fully illuminated, sporadic flashing green	Off	Bad DXLink signal quality		Check for:• Cable installation problems• Alien crosstalk• If possible, identify the hostile cable• Cable quality
Very dimly illuminated, rapid / sporadic flashing green	Off	Very bad DXLink signal quality	No video / audio / Ethernet	Check for:• Cable installation problems• Alien crosstalk• If possible, identify the hostile cable• Cable quality

Network Setup Issues

The instructions below can be used for first time setup of DXLink Modules on a network with no NetLinx Master (integrated or standalone).

Note: Before setting up the network, we recommend plugging all required Ethernet cables into the network before applying power to the DXLink Modules.

To set the IP, connection, and device parameters on a DXLink Module:

1. Set the DIP switch on the DXLink Module to:

2. 1 and #3 Toggles - ON

3. 2 and #4 Toggles – OFF

4. Attach the DXLink Module via its ICS LAN 10/100 port to the network or PC.

5. Power up the DXLink Module.

The DXLink Module will get a DHCP address or default to 169.254.2.2 (or if the module is in Static IP Mode, the address will be 192.168.1.2).

1. Establish a Telnet connection to the DXLink Module and set up the network parameters using the following three commands:

2. SET IP

3. SET CONNECTION

4. SET DEVICE

5. Enter REBOOT.

Note: If you cannot locate the DXLink Module in the Online Tree, you can reset the factory default by holding the ID button during power up until the LEDs blink in unison and then releasing the ID button. This will revert the DXLink Module to DHCP mode. Start again at Step 1 above.

Technical Support

If this manual has not satisfactorily answered your questions regarding the DXLink Transmitters and Receivers or they are not operating as expected, please contact your AMX representative or technical support. Have the serial numbers for the modules ready. If the modules are connected to a switcher, locate the serial number for the switcher too.* We recommend recording the serial numbers in an easily accessible location.

Appendix A – Upgrading the Firmware

Overview

The NetLinx Studio software application (available for free download from www.amx.com) provides the ability to transfer KIT files to NetLinx devices such as DXLink Transmitters and Receivers. The firmware on the Transmitters and Receiver can be upgraded in the field.

Endpoint System (with a Switcher)

When a Transmitter and/or a Receiver are being used in conjunction with a switcher as an endpoint system, the switcher's integrated Master is used for the KIT file transfer. FIG. 40 shows a Transmitter and a Receiver bound to the integrated Master in an Enova DGX 32 in NetLinx Studio's OnLine Tree. Follow the instructions on the top of page 106 to prepare an endpoint system for KIT file transfer and the instructions on page 109 for the actual transfer.

FIG. 40 NetLinx Studio – Integrated Master, Enova DGX 32, DXLink Transmitter, and DXLink Receiver

Extender System (Standalone)

When a standalone Transmitter and Receiver Module pair are being used as an extender system, the KIT file transfer can be done one of two ways:

• The module can be bound to any Master on the network and then unbound when the file transfer procedure is complete.
• If a Master is not present on the network, a Virtual NetLinx Master can be set up using a PC (see page 121).

Follow the instructions on the bottom of page 106 to prepare an extender system for KIT file transfer and the instructions on page 109 for the actual transfer.

Preparing for KIT File Transfers in an Endpoint System

To prepare for KIT file transfers in an endpoint system:

1. Check to be sure #3 Toggle on the bottom of the Transmitter or Receiver is set to ON.

2. Verify that you have the latest version of NetLinx Studio on your PC.

If the version is not the latest -

- Use the Web Update option in NetLinx Studio's Help menu to obtain the latest version.

Or

- Go to www.amx.com and login as a Dealer to download the latest version.

1. Download the latest Firmware (KIT) file from www.amx.com on the DXLink Transmitter or Receiver product page to your PC. (Place KIT files on a local drive for speedy throughput.)

2. Verify the following:

a. Verify that an Ethernet/RJ-45 cable is connected from the switcher's integrated Master to the network (e.g., from the LAN 100/1000 port on an Enova DGX 32 to a LAN).

b. Verify that the target Transmitter or Receiver is connected via its DXLink connector to a DXLink Input or Output Board (respectively) on the switcher.

c. Verify that the switcher is powered on.

1. Launch NetLinx Studio and open the OnLine Tree.

2. Bind the target Transmitter or Receiver to the integrated Master: select and right-click the TX or RX; from the context sensitive menu, select Network Bind/Unbind Device (be sure the check box is selected); click OK.

1. Determine the Device Number assigned to the target Transmitter or Receiver when it was bound. For the Device Number location, see FIG. 40 on page 105. The Transmitter or Receiver is ready for the KIT file transfer.

Preparing for KIT File Transfers in an Extender System

To prepare for KIT file transfers in an extender system:

1. Verify that you have the latest version of NetLinx Studio on your PC.

If the version is not the latest:

• Use the Web Update option in NetLinx Studio's Help menu to obtain the latest version. Or

• Go to www.amx.com and login as a Dealer to download the latest version.

• Download the latest Firmware (KIT) file from www.amx.com on the Transmitter or Receiver product page to your PC. (Place KIT files on a local drive for speedy throughput.)

3. No Master on the network:

a. Use your PC to set up a Virtual NetLinx Master (see page 121) in NetLinx Studio (leave NetLinx Studio open to the OnLine Tree when done).
b. Apply power to module and set it to Static IP Mode.* The default static IP address is 192.168.1.2. (Note that when module is in Static IP Mode, the Link/Act LED will be OFF and the Status LED will be ON.)

Master on the network:

a. Launch NetLinx Studio and open the OnLine Tree.
b. Apply power to module and set it to DHCP Mode.*

1. On the bottom of module, set the DIP switch's #1 and #3 Toggles to ON. (Remember to set the #1 and #3 Toggles back to OFF when the file transfer is complete if the module does not require network connectivity.)

2. Connect an RJ-45 cable from the ICS LAN 10/100 port on the Transmitter or Receiver Module to the PC running NetLinx Studio.

3. No Master on the network (set a TCP connection from the DXLink Module to the Virtual NetLinx Master):

Note: The DXLink Module is present on the network but does not display until the following steps are completed and the workspace is refreshed.

a. From the Tools menu, select Telnet Session to open the Telnet Settings window.
b. Click New and enter the TCP/IP Address for module (192.168.1.2). Click OK.
c. Select the module's address in the List of Addresses and click OK.
d. At the prompt ( > ), enter SET CONNECTION.
e. Enter "T" for TCP/URL.
f. Enter the (Virtual NetLinx) Master IP/URL (192.168.1.100).
Use the defaults for the remaining parameters (press Enter to move from default to default).
Master on the network: Go to Step 7.

1. Right-click in the workspace and select Refresh System OnLine Tree. The module will appear in the OnLine Tree and locate the DXLink Module and the virtual device ID assigned to it (32002 in the example). For the Device Number location, see FIG. 40 on page 105. The module is ready for the KIT file transfer.

* Press and hold the ID Pushbutton for at least 10 seconds. The NetLinx LEDs toggle back and forth during this time and then blink faster in unison. Release on the faster blink. When the Pushbutton is released, the module toggles from either static to dynamic IP addressing or vice versa and remains in that mode until the ID Pushbutton is used to reset it. The module automatically reboots to complete the process.

Important Upgrade Information

Caution: Upgrading the firmware is a serious action in that if the upgrade fails, it can leave the system completely non-operational.

In the Event of Power Loss During an Upgrade

If power loss occurs before any firmware information has been transferred – when power is restored, the module will remain operational using the original firmware.

If power loss occurs after some of the firmware information has been transferred but before the transfer is complete – when power is restored, the module will time out and will not operate until a successful upgrade takes place.

Caution: If the application signals a failure, you must immediately reboot the Transmitter or Receiver and attempt to upgrade the firmware again, as the module is in an unknown state and cannot be guaranteed to be operational.

Firmware Versions

The following table contains firmware version information for the DXLink units.

Transferring KIT Files

The system will be non-operational during the upgrade procedure.

The Firmware Transfers tool in NetLinx Studio is used to map KIT files to DXLink Transmitters and Receivers. The instructions below assume that the preparations on the previous pages for an endpoint system have been completed.

To send a KIT file to a Transmitter or Receiver:

1. In NetLinx Studio from the Tools menu, select "Firmware Transfers > Send to NetLinx Device" to open the Send to NetLinx Device dialog box.

1. Click Browse (...) to navigate to the target directory. The selected directory path is displayed in the Location text box. KIT files in the target directory display under Files.
2. Select the appropriate KIT file from the list.
3. Enter the Device and System numbers for the target module in the Device and System text boxes.
4. Review the File, Connection, Address, and Target Device information for accuracy before you send.
5. Click Send to upgrade the firmware on the DXLink Transmitter or Receiver.

The Power LED blinks during the process for upgrading the firmware (this is normal). The progress of the upgrade displays in the Upload Status field. Status is also indicated in the Status bar at the bottom. The success of the upgrade or any errors that occur will be reported.*

1. Close the window when the transfer is complete.
2. When the process is complete, cycle power using the new image on the DXLink Module:

a. Unplug the desktop power supply from the AC power source and plug it back in,
b. If the power source is the switcher, unplug the RJ-45 connector from the DXLink port on the module.

1. Wait 60 seconds and refresh the System OnLine Tree, and check to be sure the firmware version matches the version selected for the upgrade.

* If an incorrect file has been selected or if the upgrade has failed, the Power LED will briefly illuminate solid green then change to a slow blink. To recover (in either case), reboot the Transmitter or Receiver and browse to select the correct file and then re-send.

Reminders

When the file transfer is complete, remember to do the following:

• Set the #1 Toggle on the DXLink Module to OFF.
• If you set the PC to Static IP Mode for a Virtual NetLinx Master file transfer, return the setting to "Obtain an IP address automatically" (see page 122).

Appendix A – Upgrading the Firmware

Appendix B – Telnet (Terminal) Commands

Establishing a Terminal Connection Via Telnet

Telnet terminal communication is accessed remotely via TCP/IP. The Transmitter or Receiver must have its own TCP/IP address for a Telnet connection. The connection can be started from the Windows taskbar (see below) or in NetLinx Studio (see the following page).

By default, a User Name and Password are not applied to the Telnet port (Port 23). Therefore, the port does not require login credentials.

Welcome Banner with and without Security Enabled:

- Without Telnet security enabled, a session will begin with a welcome banner similar to the following:

Welcome to DXLINK-HDMI-RX 0.0.106.0 Copyright AMX LLC 2011 > 

- If Telnet security is enabled, user credentials are required:

Enter username: admin
Enter protected password: ****
Welcome to DXLINK-HDMI-RX 0.0.106.0 Copyright AMX LLC 2011 > 

Note: When security is enabled, a user can retry logging in three times before being disconnected (for information on setting a username and password, see page 112).

To establish a terminal connection via Telnet at the CMD prompt:

1. From your Windows Taskbar (at the far left), select Start > Run to open the Run dialog box.
2. Type cmd in the Open field.

1. Click OK to open an instance of the Windows command interpreter (cmd.exe).
2. At the prompt (>) , type telnet followed by a space and the Transmitter or Receiver's IP address. Example:

telnet XXX.XXX.XXX.XXX

A Telnet session opens for the Transmitter or Receiver and the welcome banner appears.

1. At the prompt, type the Telnet command (see page 113) and press Enter.

To establish a terminal connection via NetLinx Studio:

1. In the Online Tree, select the DXLink unit and right-click to access the short-cut menu.

2. Select Launch Telnet Window via NetLinx Studio.

The Telnet window opens and the welcome banner appears.

1. At the prompt ( > ), type the Telnet command and press Enter.

Telnet Username and Password

The following commands are used to set the Telnet username and password for a Telnet connection:

• Set Telnet Username
• Set Telnet Password

By default, both the username and password are blank (empty strings). Performing a factory reset on the device with the Pushbutton will return these values to that default. For details, see page 69.

• Username – Setting the Username will have no effect if the password remains blank (empty string). That is defining the username alone will not result in Telnet prompting for a user login.
• Password – Setting the Password will cause Telnet to prompt for a user login, whether the username has been defined or not. If the username has been defined, this value must be entered. However, since the password can be set independently of the username, it's possible to have a password defined, but the username still at its default (blank, empty string). In this case do not enter anything for the username when prompted. Simply press Enter, which will then present the password prompt. Here, the defined password must be entered in order to successfully open the Telnet session.

Additional Notes

• Both the Telnet username and password are case-sensitive.
• Three consecutive, unsuccessful attempts to log in to Telnet will cause the Telnet window to close. Re-launching Telnet will again present the login prompt, with a fresh "batch" of login attempts.
• If a Telnet login fails because of an incorrect username, an "Invalid Password" message will appear (as opposed to an "Invalid Username" message).
  ● The username and password are saved after reboot or power cycle.
• The username and password are deleted/removed after a factory reset.

Setting a Telnet Username and Password

To set a Telnet username and password:

1. Establish a terminal connection via Telnet (see page 111).
2. Type Set Telnet Username, and press Enter.

a. The program will prompt you to enter a new Telnet username; enter a username and press Enter.
b. The program will indicate that the username is being stored.

1. Type Set Telnet Password, and press Enter.

a. The program will prompt you to enter a password; press Enter twice to clear both the Telnet username and password.
b. Enter a password and press Enter.
c. The program will prompt you to re-enter the password; re-enter the password and press Enter.
d. The program will indicate that the password is being stored.

Telnet Commands

The Telnet commands listed in the table below can be sent directly to the Transmitter or Receiver via a Telnet terminal session.

• The default Telnet port is 23. A value of 0 (zero) disables the Telnet server.
• Telnet is enabled by default.

In the terminal program, type Help or a question mark (?) and press Enter to access the Help Menu and display the terminal commands described in the table below.

Master Connection Modes

The mode of communication used for connection to the Master is specified via the SET CONNECTION Telnet command (see page 116).

Connection mode setting options are AUTO, TCP URL, UDP URL, or NDP (default) as described:

• AUTO – This mode utilizes TCP communication. It looks for a matching System Number and attempts to come online with the first Master it sees with that System Number.
• TCP URL – TCP; the Master is specified via URL.
• UDP URL – UDP; the Master is specified via URL.
• NDP – UDP; this mode utilizes the NDP binding process to assign the DXLink Module (the physical device) to a Master (or Virtual Master) via NetLinx Studio. Once bound, communications are conducted via UDP.

Note: In URL modes, the Master can use either an IP address or a DNS name.

TCP vs. UDP

• TCP – Protocol has a built-in retry mechanism.
• UDP – Protocol does not have a built-in retry mechanism, but consumes fewer resources on the Master. AMX's UDP implementation of NetLinx employs a retry mechanism to provide the reliability of TCP with the resource efficiency of UDP.

URL vs. NDP vs. Auto

Determining which connection method to use for Master Connection Mode is essentially a matter of deciding what information the device should use to identify the correct Master to connect to.

The default mode is NDP; the mode can be changed via the SET CONNECTION Telnet command (see page 116).

• URL – The device connects to the Master with the specified URL. The device must be configured with the URL of a specific Master via the SET CONNECTION Telnet command (see page 116).
• NDP – The device connects to the Master it's been bound to, which is based on the Master's MAC address. The binding is configured via NetLinx Studio. Once bound, the device must be unbound using either NetLinx Studio or the Telnet NDP UNBIND command before being re-bound to a different Master.
  Alternatively, NDP devices can be bound/unbound via options on the Master's Web Configuration pages (System > Manage NetLinx). For details, refer to the NetLinx Integrated Controllers - WebConsole & Programming Guide (System - Manage NetLinx section).
• Auto – The device connects to the first Master it finds with the specified System Number. The device must be configured with the desired system number via the SET CONNECTION Telnet command (see page 116).
  Use of this method requires that only one Master has any particular system number and is visible to the subnet. If this is the case, then Auto is the simplest choice. However, with Auto, you are not hard-bound to a particular Master. Therefore, if at some point in the future, another Master is configured with the same system number, the result is that the DXLink Module could show up on that other Master.

Notes on Specific Telnet Clients

Telnet and terminal clients exhibit different behaviors in some situations. This section states some of the known anomalies.

Windows Client Programs

Anomalies occur when using a Windows ^® client if you are not typing standard ASCII characters (i.e., using the keypad and the Alt key to enter decimal codes). Most programs will allow you to enter specific decimal codes by holding Alt and using keypad numbers.

Example

For example, hold Alt, hit the keypad 1, then hit keypad 0, then release Alt. The standard line feed code is entered (decimal 10). Windows will perform an ANSI to OEM conversion on some codes entered this way because of the way Windows handles languages and code pages.

The following codes are known to be altered, but others may be affected depending on the computer's setup.

- Characters 15, 21, 22, and any characters above 127.

This affects both Windows Telnet and Terminal programs.

Linux Telnet Client

The Linux Telnet client has three anomalies that are known at this time:

• A null (\00) character is sent after a carriage return.
• If an “Alt 255” is entered, two of the “255” characters are sent (per the Telnet RAFT).
• If the code to return to Command mode is entered (Alt 29 which is ^]), the character is not sent, but the Telnet Command Mode is entered.

Appendix C – Virtual NetLinx Master

Overview Virtual NetLinx Master (Masterless)

A Virtual NetLinx Master can be created using your PC, which allows NetLinx Studio to facilitate direct file transfers to a DXLink Transmitter or Receiver when a Master is not available.

Four basic procedures must be completed for Virtual Master file transfers:

• Set the PC to a static IP address (see below).
• Create a Virtual Master in NetLinx Studio (see page 123).
• Prepare the DXLink Transmitter or Receiver by placing it in Static IP Mode, assigning a device ID, and setting the connection type to TCP (see page 125).
• Transfer the files using a Virtual Master TCP/IP connection (for IRL file transfers, see page 73; for Firmware file transfers, see page 105).

Setting PC to Static IP Address

Important: When you change the PC's settings to a static IP address, the address must be in the same subnet as the DXLink unit (the default static IP address for DXLink Transmitters and Receivers is 192.168.1.2).

Important Information for PCs with Multiple Network Access Points

If the PC has more than one point of network access (multiple NIC cards or wireless networking), check to see if one of the connections uses an IP address of 192.168.1.x before proceeding.

To check for multiple networks:

1. Open the PC's Start menu (at the lower left of the desktop on the Taskbar) and select Run.
2. Enter cmd and click OK.
3. At the prompt, enter ipconfig /all and press the Enter key.
4. Check the IP Addresses under Connection.

If the PC or Laptop is currently using a connection with an IP address of 192.168.1.x, you will need to disconnect the connection.

To disconnect a network connection:

1. Click Select.

2. Click OK to save the changes and close the dialog box.

The Virtual Master displays in the NetLinx Studio's OnLine Tree.

Important: When transferring files via a Virtual Master, a direct connection must be made between the module and the PC via the module's ICS LAN 10/100 port.

Preparing a DXLink Module to Work with a Virtual Master

Preparing the DXLink Transmitter or Receiver to work with a Virtual Master requires placing the unit in Static IP Mode, assigning it a device ID, and setting the connection type to TCP.

Note: When using the instructions below, only one DXLink Module can be connected to the Virtual Master at a time because the static IP address is the same for all modules.

To place a DXLink Module in Static IP Mode:

1. Connect the DXLink Module via its ICS LAN 10/100 port to the PC acting as a Virtual Master.

2. Set the DIP Switch's #1, #2, and #3 Toggles to ON.

3. Apply power to the DXLink Module.

4. Once the DXLink Module has booted up (the Power LED on the front of the module turns a constant green, to indicates a ready state), press and hold the ID Pushbutton for at least 10 seconds.

5. The NetLinx LEDs toggle back and forth during this time and then blink faster in unison; release when the faster blink starts.

6. When the Pushbutton is released, the DXLink Module toggles either from static to dynamic (DHCP) IP addressing or vice versa and remains in that mode until the ID Pushbutton is used to set it again.

7. The DXLink Module automatically reboots to complete the process.

To assign a device ID and set the connection type:

1. From the Tools menu in NetLinx Studio, select Telnet Session. The Telnet Settings dialog box opens.

2. Click the New button.

The New Telnet Address dialog box opens.

1. Enter the default static IP address for the module: 192.168.1.2 and click OK.

2. Select the new address in the List of Addresses.

3. Click the Select button and click OK.

4. A Telnet session opens.

5. At the prompt (>) , type SET DEVICE and press Enter.

6. For the variable , the valid range of device numbers is 0 to 31999.

7. Setting a device number does not require a reboot to take effect.

8. At the prompt, type SET CONNECTION and press Enter.

9. Specify TCP for the connection and the PC's static IP address for the Master.

The Transmitter or Receiver displays under the Virtual Master and is now ready for file transfers.

Note: The process can be repeated for additional Transmitters and Receivers.

File transfers via a Virtual Master:

• IRL file transfers, see page 73
• Firmware file transfers, see page 105

Important: Once you have finished using the Virtual Master – If you disabled a network connection before setting the PC's static IP address, be sure to disable the Virtual Master's network connection and enable the original connection.

Appendix D – Cable Details and Pinout Info

Overview

The DXLink units; Multi-Format TX, HDMI TX, Wallplate TX, Decor Wallplate TX, and HDMI RX; all have connectors for HDMI. The Multi-Format units have an additional port for HD-15 connectors.

The following table shows the video connections available on each of the DXLink units.

Connection	DXLink Units
	HDMI TX Multi-Format TX Wallplate TX Decor Wallplate TX HDMI RX

Appendix F – Supported Output Resolutions

Appendix G – Ground Wire Attachment

Applicability

This appendix covers attaching a ground wire to a DXLink Module without a designated ground location. If the module has a designated ground screw, see page 45.

If the system is experiencing problems with delivery of DXLink signals to/from an Enova DGX Digital Media Switcher or Enova DVX Solution, adding a ground wire from the TX/RX to the switcher may improve performance. The problem is likely caused by the use of a single phase powered system that does not provide an earth ground for a source or destination's chassis and shields. This can inject unnecessary AC voltage on the HDMI cable shield that can lead to DXLink signal integrity issues. To check for indications of this type of power in the system, look for a two pronged plug or a cord that has only two wires.

Note: Technically this type of grounding is only required when a DXLink Transmitter or Receiver is connected to an ungrounded device, but this added grounding measure can be used at the discretion of the installer.

Items Required

☐ Small adjustable wrench or socket driver
☐ 6 foot ground wire with ring terminal ends (provided)

Note: Currently shipping DXLink Transmitters and Receivers provide a designated ground location on the rear of the chassis for attaching a ground wire. For instructions on attaching a ground wire to DXLink Modules or DXLink Wallplates with a designated ground location, see page 45.

Attaching a Ground Wire to a Common Earthed Ground

Connect the running end of the ground wire (fixed end attached to DXLink Module or Wallplate) to a common earthed ground (ideally, referenced to the Enova DGX Switcher).

Important: If one DXLink Transmitter or Receiver is grounded, any remaining ungrounded units that are connected to the same board on the Enova DGX Switcher must also be grounded.

Attaching a Ground Wire to Module without Designated Ground

Earlier model DXLink Transmitter and Receiver Modules without a designated location support chassis ground attachment through the HDMI jackscrew on the rear of the chassis.

Important: Before attaching the ground wire to the chassis, ensure all connectors are clear.

To attach a ground wire to a module with a jackscrew:

1. If powered, power down the DXLink Module.
2. Remove the jackscrew and silver washer above the HDMI connector.

FIG. 44 Remove jackscrew and washer above HDMI connector

1. Secure the ring terminal of the ground wire against the chassis with the jackscrew and washer.
2. Ensure the ground wire is positioned so that it does not interfere with any of the connectors.

FIG. 45 Position ground wire away from connectors

1. Attach the ground wire to a common earthed ground (see "Attaching a Ground Wire to a Common Earthed Ground" on the previous page).
2. Continue the installation process (or reapply power to the module).

Appendix H – EDID Programming

DGX Configuration Software Overview

Important: Because signals routed through DXLink Transmitters normally produce a quality image, you will not need the information in this appendix unless the installation has special EDID requirements for VGA.

AMX's DGX Configuration Software has a tabbed view for EDID Programming. This view can be used to re-program the EDID EEPROM chips for the HD-15 connectors on the DXLink Transmitters, allowing for custom configuration of the EDID data that is stored on them.

Note: The remaining tabbed views in the software do not apply to the DXLink units. Scaling and HDCP settings can be applied via SEND_COMMANDs (see the chapter "NetLinx Programming of DXLink Transmitters and Receivers" on page 79). If a DXLink Receiver is connected to an Enova DGX Output Board, DGX Configuration Software can be used via the switcher for scaling (see the "Instruction Manual – Enova DGX 8/16/32."

DGX Configuration Software is available at www.amx.com (on the Multi-Format Transmitter's product page) and includes a standard Help file with detailed information.

PC System Requirements for DGX Configuration Software v1.0.5

☐ Windows 7 and Windows XP Professional
☐ Minimum Hardware: 166 MHz, 128 MB RAM, 36 MB of free disk space*, 800x600 display, serial port, video card with dual outputs (see Caution below)
Recommended Hardware: 2.0 GHz, 512 MB RAM*

* The installation process requires 36 MB of disk space for the DGX Configuration Software installer. Once installed, the program requires 10 MB of disk space.

Caution: We strongly urge the user not to use video cards with DMS-59 connectors. Video cards with DMS-59 connectors have been shown to fail consistently and, in the worst case, can corrupt an EDID data file. A laptop PC with a VGA or DVI out is a good solution. Cards with 2 DVI connectors, 2 VGA connectors, or 1 DVI and 1 VGA connector are also acceptable.

Software Installation on PC

Important: Administrator rights are required to install DGX Configuration Software.

To install DGX Configuration Software:

1. From the DXLink Multi-Format Transmitter's product page at www.amx.com (under Application Files on the right) double-click, "DGX Configuration Software."
2. Click "I Accept" for the AMX License Agreement, and then select Open to download the file.
3. Optional – Select DGX_Config_SoftwareReadMe_vX_X to read about the software before installation.

5. In the Compressed (zipped) Folders dialog box, click Extract All.
6. Select a destination for the files.
7. When the download is complete, click the application file and follow the directions in the installation wizard.

DXLink Connection to PC

To use DGX Configuration Software with a DXLink Transmitter:

1. Attach one end of a USB mini-B cable to the Program port on the front of the Multi-Format Transmitter (on the Wallplate TX, the Program port is on the left side; on the Decor Wallplate TX, the Program port is in the center on the front under the customer provided cover plate).
2. Attach the open end of the USB mini-B cable to the PC where the DGX Configuration Software was installed.
3. Apply power to the Transmitter. If power is via the DXLink connection, then apply power to the power sourcing device (i.e., switcher, PDXL-2, or PS-POE-AT-TC).
4. On the PC, open the DGX Configuration Software.

Note: The PC will automatically establish a virtual COM port on the Transmitter.

1. If changing the communication settings is necessary*:

a. From the Communication menu (in the DGX Configuration Software), select Serial Port.
b. Select Change Settings to change the serial port and/or the baud rate for the PC's serial port. The baud rate for the PC must match the baud rate for the Transmitter. The recommended (default) baud rate setting for serial communication with DXLink Transmitters is 9600.
c. If you changed any of the settings, from the Communication menu select Refresh Device Lists.

1. Select the EDID tab in the interface (defaults to the Scaler Mode tab**).

* If you are unsure of the USB Serial Port (COM ) being used, on the PC go to Start > Control Panel > Device Manager and expand the "Ports" to verify the COM number.

** The remaining tabs do not apply to the DXLink Transmitters. Scaling and HDCP settings can be applied via SEND_COMMANDs (see page 79).

When the DXLink Multi-Format TX is connected to a PC running DGX Configuration Software, the following applies:

• DGX Configuration Software displays the connected Transmitter only.
• File menu – Select Open File to load an .edid file to the program. Select Save to File to save an .edid file containing the currently displayed settings in the EDID Programmer view.
• Communication menu – Use to change the serial communication settings. This menu also includes the option to “Refresh Device Lists,” which will refresh the device list in the EDID Programmer tab.
• Utilities menu – This menu does not apply to the DXLink Transmitters.
• Help menu – Access the Help file for the program, open a link for the Web Update option (to download updates for the program), and view current version information.
• Messages in the bottom pane of the DGX Configuration Software dialog box report status of operations. Messages can be copied* for technical support purposes.

* Right-click on a message to access a short-cut menu with options to Copy Selected, Copy All, or Clear. When copying multiple messages: either select consecutive items by holding down the Shift key and clicking the first and last item or select nonconsecutive items by holding down the Control key and clicking on each item.

EDID Programmer View

From the EDID Programmer view, EDID EEPROM chips for the HD-15 (VGA) connector on the Transmitter can be re-programmed if necessary.

Note: The EDID Programmer will not work in conjunction with the HDMI connector on the TX.

EDID Overview

EDID (Extended Display Identification Data) is a data structure established by the Video Electronics Standards Association (VESA) to enable plug-and-play support by enabling easy configuration of a computer's graphics subsystem based on the capabilities of the attached display device.

EDID information includes items such as the following:

• Manufacturer's name
• Product type
  ● Supported video resolutions and refresh rates
  • Color space and filter chromaticity
• Detailed timings

When a computer is directly connected to a display device, it can use the display device's EDID information to determine an initial compatible video signal to send. With the computer's display controls, the user can modify this selection to another compatible signal based on the provided EDID information.

DXLink Equipment and EDID

In cases where the HD-15 (VGA) input on a DXLink Transmitter are used and a resolution incompatibility exists (or if the source device needs a specific resolution or a limited set of resolutions), the DXLink Transmitters have the ability to update the VGA EDID emulation file (by updating the EEPROM chip) which comes preloaded with an AMX VGA EDID set.

The AMX VGA EDID set consists of a number of common EDID settings (for VGA timing details, see page 131). In most cases, the DXLink Transmitter can be used as is from the factory with no adjustments.

The DGX Configuration Software with EDID programming functionality has been provided for cases where a user defined VGA EDID set is desired (this must be a subset of the supported input resolutions shown in Appendix E; see page 131).

The EDID Programmer view can be used for writing user defined VGA EDID data to the DXLink Transmitter's HD-15 input.

Reading and Saving EDID Data from a DXLink TX's HD-15 (VGA) Input Connector

The DGX Configuration Software reads the EDID data from the USER EDID 1 EEPROM location, regardless of the VIDIN_EDID setting.

Important: Unless a custom EDID has been previously written to the input, attempting to read the EDID will result in a Read Error message.

The EDID data can be read to confirm the correct EDID has been programmed.

To read and save EDID data from a DXLink Transmitter:

1. On the PC, open the DGX Configuration Software and select the EDID Programmer tab.
2. Under Inputs/Outputs on the left, expand the device tree, and select the HD-15 input.
3. Click Read to read the VGA EDID information currently on the HD-15 input.
   The EDID data appears in the EDID read-only field on the right.

Tip: In the EDID Programmer view, the Save to File option under the File menu can be used to save the EDID information as an .edid file. The saved file can be opened as a text file (from the File menu, select Open File) and edited or opened and written to an input (click the Write button).

Read Error Message

A Read Error message will appear if the Multi-Format Transmitter has never been programmed with a valid/custom EDID or if the unit has been programmed with a corrupted EDID. A Read Error message will also appear when attempting to read the EDID after sending a FACTORYAV SEND_COMMAND, which re-initializes the VGA USER EDID 1 EEPROM and resets the VIDIN_EDID setting to ALL RESOLUTIONS (which is AMX_0500_003).

Writing EDID Data to a DXLink Transmitter's HD-15 (VGA) Input Connector

The instructions that follow tell how to use the EDID Programmer view to write user defined VGA EDID information to the HD-15 input connector on a DXLink Transmitter. User defined VGA EDIDs are currently available from technical support. A library of VGA EDID files will be available on at www.amx.com in conjunction with a future firmware release.

To write VGA EDID data to a DXLink Transmitter:

1. Download the VGA EDID set provided by technical support.
2. On the PC, open the DGX Configuration Software and select the EDID Programmer tab.

1. Under Inputs/Outputs on the left, expand the device tree, and select the HD-15 input.
2. From the File menu, select Open File to select the VGA .edid file that was downloaded in Step 1.
3. Click Write to write the VGA EDID information to the HD-15 input.

Tip: You can confirm that the new VGA EDID data was written to the HD-15 input by selecting the HD-15 input and clicking on the Read button or by using the SEND_COMMAND ?VIDIN_EDID, which will return: VIDIN EDID-USER EDID 1.

Important: You can revert to the factory default EDID for the HD-15 input by using the SEND_COMMAND VIDIN_EDID-ALL RESOLUTIONS (i.e., AMX_0500_003).
