Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

ESD Warning

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. ESD protective equipment can be obtained from 3M™, Desco Systems

, and other such vendors.

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.

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.

USB LED

The USB LED on the front of a Transmitter or Receiver Module monitors the USB port on the rear of the unit. The USB LED illuminates (yellow) when a USB device is detected (the port default is “enabled”).

To disable the port on the Transmitter, either disconnect the cable or send the following SEND_COMMAND: USB_HID_SERVICE-DISABLE. The enable/disable command persists through power cycling. To enable the port, send: USB_HID_SERVICE-ENABLE. The USB ports support a limited number of SEND_COMMANDs, see page 94.

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.

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 Descriptions.

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 38).

• When 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 40).

Extender Mode:

• When a TX is directly connected to an RX, the system is in Extender Mode (see example on page 41).

For further information, reference #2 Toggle DIP switch settings for DXLink Mode (see page 44) and DXLink System SEND_COMMANDs (see page 96).

Quick Reference Table – Modes for Handling Addressing/Networking

Mode Description

IP Addressing Mode

ID Mode

Ethernet Modes Ethernet Modes refer to the LAN configuration settings.

IP Addressing Modes refer to network connection settings. 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 64.

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 68.

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 108.

Master Connection Modes

IR SEND_COMMAND 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 116.

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.

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 61), or with SEND_COMMANDs (see page 80), or through DGX Configuration Software when scaling is being done via an Enova DXLink Output Board.

Auto Mode (Default):

• Auto Mode (SmartScale

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.

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 shall only be run within a common building. “Common building” is defined as: Where the walls of the structure(s) are physically connected and the structure(s) share a single ground reference.

Installation and Setup

Elevated Operating Temperature

The maximum rated ambient temperature is 104° F (40° C) 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 47).

Installation and Setup

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 41).

An understanding of the DIP switch settings (see page 44).

When used with an Enova DGX Digital Media Switcher – The system’s power requirements must be

determined (see page 41).

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 98).

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 40).

Extender Mode (Standalone) – A standalone DXLink TX/RX pair are connected directly to each other as a

simple extender solution (see page 41).

* The switcher can be either an Enova DGX Switcher or an applicable Enova DVX Solution (see “Product Compatibility Tables” on page 12).

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 systems 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 78). 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 43.

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 78).

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 78).

Extender Mode (Standalone): Example of Typical System Setup

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.

Important Power Considerations for Enova DGX Endpoint Systems

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 47).

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.

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).

Installation and Setup

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 or DXLink Power Injectors: PDXL-2 (FG1090-170) or PS-POE-AT-TC (FG423-84).

Wallplate and Decor Wallplate Transmitters must be included in the power calculations unless they are being powered by a DXLink power injector (must be AMX approved).

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 table below to determine which situation applies and any actions that may be required:

System Condition Result / Required Action

Within power budget The system will continue to run; okay to leave it powered until the

failed power supply is replaced.

Over power budget The system will continue to run; however, we do not recommend

Enova DGX 8/16

Enova DGX 32

Within power budget The system will continue to run; okay to leave it powered until the

Over power budget The remaining power supply will turn off. If enough DXLink

leaving it powered until the failed power supply is replaced, unless enough DXLink Transmitter or Receiver Modules are removed (or otherwise powered) to bring the system’s power budget within its maximum limit. (Another option is to remove some of the input and/or output boards.)

failed power supply is replaced.

Transmitter or Receiver Modules are removed (or otherwise powered) 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 102).

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.

Installation and Setup

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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, which allows Ethernet pass through. It does not affect network activity over DXLink. (For SEND_COMMANDs to disable/enable ICS LAN functionality, see page 96.)

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 45.

#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 43.

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 43.

Setting DIP Switch #2 to Set the DXLink Mode

#2 Toggle can be set to automatically or manually select the DXLink Mode (to either Extender or Endpoint) for a given Transmitter/Receiver Module. Default state for #2 Toggle OFF is auto selection of DXLink Mode based on connection to another device. When it’s ON, the default is Endpoint Mode (used for Master controlled serial/IR data transfer).

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 45.

#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 require IR and/or Serial control 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 (if needed), and #3 Toggle needs to be ON to enable network connectivity.

Installation and Setup

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

Note: On either setting, the DXLink Mode may be set via SEND_COMMANDs (see page 96). 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 (IP addressing) 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).

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 below.

#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 61). 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 43).

Common Scenarios DIP Switch Toggle Settings

Standalone Setup – TX/RX pair direct connection 1 2 3 4

AV signals only (plus serial/IR pass through) OFF OFF OFF OFF AV with Ethernet pass through to networked device* (plus serial/IR pass through)

AV with NetLinx control of TX/RX unit and serial/IR ports**

Switcher Setup – TX/RX with Enova DVX/DGX Switcher 1 2 3 4

AV signals only OFF OFF OFF OFF AV with Ethernet pass through to networked device*

AV with NetLinx control of TX/RX unit and serial/IR ports

AV with NetLinx control of TX/RX unit and serial/IR ports, plus Ethernet pass through to networked device*

* 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 and #3 Toggles must

be ON. #2 is only required on each module

if serial and/or IR control is required from the Master.

Designated ground screw and washer

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 134.

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:

If powered, power down the DXLink Module.

2. Remove the designated ground screw and washer from the rear of the module.

Important Twisted Pair Cabling Requirements and Recommendations

The following requirements and recommendations apply to cabling DXLink (RJ-45) connectors:

DXLink cable runs require shielded category cable (STP) of Cat6 (or better).

DXLink twisted pair cable runs for DXLink equipment shall only be run within a common building.*

DXLink delivers 10.2 Gb/s throughput over shielded category cable. Based on this bandwidth requirement,

we recommend following industry standard practices designed for 10 Gigabit Ethernet when designing and installing the cable infrastructure.

The cables should be no longer than necessary to reach the end-points. We recommend terminating the cable

to the actual distance required rather than leaving any excess cable in a service loop.

For complete cable specifications, see page 31.

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.

* “Common building” is defined as: Where the walls of the structure(s) are physically connected and the structure(s) share a single ground reference.

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 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 41.

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 47).

be altered in any way. Remote power can only be provided via a switcher or a DXLink

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:

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.

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 vice 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 on each module.

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:

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

2. Use the command RXON to enable this port on the Transmitter and the Receiver. (For complete Serial

SEND_COMMAND programming information, see page 92.)

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 44. For Serial SEND_COMMANDs, see page 92.

Installation and Setup

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 27. (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 will be passed through directly in Extender Mode when #2 Toggle is set to OFF (default). When #2 Toggle is set to ON, the Master handles the IR control. When a Transmitter and Receiver are connected to a switcher, they will default to Endpoint mode and the integrated Master handles the SEND_COMMANDs.

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.

IR03 External IR Receiver Module (not included)

FIG. 35 IR Receiver cable (FG-IR03)

To connect an IR Receiver to a module:

Connect the jack on the IR03 External IR Receiver Module cable (FG-IR03) to the IR RX port on the module.

2. Run the cable and attach the IR receiver bud so that it has a clear line-of-sight with the intended remote control

device.

CC-NIRC NetLinx IR Emitter Cable (not included)

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

To connect an IR Emitter to a module:

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 72) 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 44. For IR SEND_COMMANDs, see page 88.

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 67.

Note: ID Pushbutton functions can also be implemented using Telnet commands (see page 108).

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

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 80).

Technology in action).

To set the scaling option (mode):

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 80).

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.

Installation and Setup

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 following methods:

Using the SEND_COMMAND: PERSISTAV (for details, see page 96).

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.

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 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 43). 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 input (out a DXLink output) DXLink input (out a DXLink output)

 Enova DGX 32, DXLink input (out a DXLink output)  Enova DGX 16,  DXLink Receiver  display device as an HDMI signal.

 DXLink Transmitter  Enova DVX-3155HD,

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 45).

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 67)

Telnet commands (see page 108)

* “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 45). 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

DNS3 192.168.1.1

Network Configuration

DHCP Mode

Important: DHCP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 45). The #3 Toggle must

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

be ON before the device is accessible via SEND_COMMANDs.

(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.

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.

Network Configuration

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 169.254.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 109) 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 108. The appendix also includes a section on “Master Connection Modes” on page 116.

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 68) Reset the unit to its factory default settings, which affects the parameters but not the firmware version (see

page 69)

Restore the unit to its factory firmware image, which affects both the firmware version and the parameters

(see page 70) 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 108).

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 45), 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 69). 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:

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 (DHCP) 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.

Network Configuration

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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:

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.

4. In the ID Mode section, enter the Device and System numbers that you want assigned to the device in the

appropriate text boxes.

5. 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.”

6. 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 later) 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.

Network Configuration

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 116)

Unbound state

No IRL files

* For a complete list of factory parameters, see the table on page 66.

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:

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.

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.

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

3. 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.

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.

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

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

Network Configuration

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

Tip: In the following two procedures – if you start a press and hold sequence with the ID Pushbutton and then decide not to change the settings, before you release the ID Pushbutton remove power from the unit to abort the procedure (remember, power can be applied via the external power supply or over DXLink, so one or both sources of power may need to be removed).

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:

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:

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.

3. 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.

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

reboot. The Transmitter or Receiver automatically reboots to complete the process.

* For a complete list of factory parameters, see the table on page 66.

To restore Wallplate TX or Decor Wallplate TX to its factory default firmware image:

Note: 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.

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.

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

Troubleshooting

Overview

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

Five 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 102.

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 43).

 SEND_COMMANDs – double-check the command and the port number specified and re-send the

command (see page 78).

 If any changes have been made, try resetting the unit to the factory defaults (see page 69).

Troubleshooting

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.

Troubleshooting

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

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 47.

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 56.

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.
