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 a DX-RX; others may cause damage. Also note that TX and RX compatibility with Enova DGX DXLink boards applies when the boards are used in Enova DGX 8/16/32/64 enclosures and in Enova DGX 100 Series enclosures.

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.

DX-TX – The DX-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 a DX-RX), or directly to a DX-RX.

The 232 port (RS-232) on the DX-TX supports bidirectional serial data via the twisted pair cable to/from the 232 port on a DX-RX. The DX-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 DX-RX), or directly to a DX-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 a DX-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.

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 DX-RX. Direct connection requires either PDXL-2 (FG1090-170) or PS-POE-AT-TC (FG423-84).

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver	7

Product Overview and Specifications

DX-RX – The DX-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 DX-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 DX-RX supports bidirectional serial data via the twisted pair cable to/from the 232 port on the DX-TX or HDMI TX. The DX-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 DX-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 20 along with page references to complete information.

DX-TX and HDMI TX

The USB-B port on the rear of the DX-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 DX-RX. As the Host port, it is connected to a PC and passes through information via the DXLink connection to the DX-RX. A USB (mini-B) Host port is also available on the Wallplate TX and a USB (mini-AB) Host port is available on the Decor Wallplate TX.

DX-RX

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

HID Devices and Windows 8

Windows 8 will not wake up from a DXLink connected keyboard or mouse unless the properties for the HID device are set to allow the device to wake the computer. (Note that even a hot plug of the USB cable will not restore connectivity.)

To set Windows 8 to work with DXLink modules and HID devices:

1.On the PC, go to Start > Control Panel > Device Manager and expand “Keyboards.”

2.Right-click the HID Keyboard Device and select Properties. The HID Keyboard Device Properties dialog box opens.

5.Repeat steps for HID mouse (in the Device Manager dialog box, expand “Mice”).

HID Devices

A list is available of HID devices which have been tested and found to be working well with the latest firmware (see “DXLink - HID supported Devices” on the DXLink Receiver’s product page at www.amx.com).

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_SERVICEDISABLE. 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 77.

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 DX-TX, HDMI TX, and DX-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 DX-TX or HDMI TX or to the IR RX port on the DX-RX, allowing IR signals to be received from a compatible IR remote control. The IR03 allows the DX-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 DX-RX. This allows IR signals to be sent to the source device from the DX-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 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 28).

•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 30).

Extender Mode:

•When a TX is directly connected to an RX, the system is in Extender Mode (see example on page 31).

For further information, reference #2 Toggle DIP switch settings for DXLink Mode (see page 35) and DXLink System SEND_COMMANDs (see page 79).

Quick Reference Table – Modes for Handling Addressing/Networking

Mode	Description

IP Addressing	IP Addressing Modes refer to network connection settings. By default, all network connection settings are turned OFF.
Modes	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 52.

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 57.

Ethernet Modes	Ethernet Modes refer to the LAN configuration settings.
	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 halfor 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 90.

Master	Master Connection Modes refer to the modes of communication used for connection to the Master as specified via
Connection	the SET CONNECTION Telnet command.
Modes	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 97.

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver	20

	Product Overview and Specifications

Quick Reference Table – Modes for Handling Addressing/Networking (continued)
Auto-setup Mode	In auto-setup mode, endpoints are automatically discovered by and connected to an Enova DGX
	100 Series Switcher using a single IP address. For this mode, all of the following requirements must
	be met. If not, the endpoint will no longer reside in auto-setup mode and must be either bound to
	the integrated Master (see page 52) or reconfigured to meet the requirements.
	Endpoint must be connected to a DXLink Input Board in an Enova DGX 100 Series
	Switcher (or Enova DGX 8/16/32/64 with upgraded 100 Series CPU)
	Endpoint must have IP mode set to DHCP for setup (self-configures to Static IP on
	private LAN)
	Endpoint must have the master connection type set to NDP
	Endpoint must not be bound to a Master via NDP (traditional binding process)
	IMPORTANT: If auto-setup is being used, Telnet is the only way to access some of the network
	settings. Also note that some network settings will disable auto-setup.
	For additional information on the auto-setup feature, see the Hardware Reference Manual –
	Enova DGX 100 Series Digital Media Switchers.

IR SEND_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 73.

Quick Reference Table – Modes for Handling Video Processing

DXLink Power	• DXLink Twisted Pair Transmitters (DX-TX, DX-TX-DWP, and DX-TX-WP): Power can also be
		supplied by a DXLink Power sourcing device such as an Enova DGX 8/16/32/64 Digital Media
		Switcher or compatible Enova DVX All-In-One Presentation Switcher (DVX-3155HD, 3156HD,
		or 2155HD), PS-POE-AT-TC High Power PoE Injector (FG423-84) or PDXL-2 Power over DXLink
		Controller (FG1090-170). AMX does not support the use of any other power supplies or
		PoE injectors as these may potentially damage the DXLink equipment. To use PS-POE-AT-TC as a
		power source the DX-TX Transmitter and the DX-TX-DWP and DX-TX-WP Transmitter Wallplates
		require firmware v1.2.40 or above.
	• DXLink Twisted Pair Receiver (DX-RX):
		Power can also be supplied by a DXLink Power sourcing device such as an
		Enova DGX 8/16/32/64 Digital Media Switcher or compatible Enova DVX
		All-In-One Presentation Switcher (DVX-2150HD, or 2155HD), PS-POE-AT-TC High Power
		PoE Injector (FG423-84), PDXL-2 Power over DXLink Controller (FG1090-170), or
		SDX-510M-DX Solecis 5x1 Multi-Format Digital Switcher (FG1010-315). AMX does not
		support the use of any other power supplies or PoE injectors as these may potentially
		damage the DXLink equipment. To use PS-POE-AT-TC as a power source the DX-RX
		Receiver requires firmware v1.0.80 or above.
	• Power Budget for Transmitters and Receiver:
		When installed in conjunction with the Enova DGX Digital Media Switcher, use the Enova
		DGX Configuration Tool located at www.amx.com/enova to determine the power
		requirements of the configuration and whether any of the DXLink Transmitters or Receivers
		should be powered with the local power supplies or the supported Power over DXLink
		injector. The configuration tool contains instructions on how to determine power
		requirements.

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver	26

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).

DX-TX, HDMI TX and DX-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.

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 37).

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

IMPORTANT: The setup information in this manual applies to TXs and RXs in an Enova DGX 8/16/32/64 system or in an Enova DGX 100 Series system with the auto-setup feature disabled. When the auto-setup feature for an Enova DGX 100 Series Switcher is enabled (the default), any modules or wallplates are automatically discovered and connected to the switcher using a private network hosted by the integrated Master (for complete information, see the “Hardware Reference Manual – Enova DGX 100 Series Digital Media Switchers”). In an Enova DGX 8/16/32/64 system, each module or wallplate bound to the system with traditional NetLinx binding (see page 52) acquires its own IP address from the public network (for network configuration, see page 52).

Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver	27

Installation and Setup

Setup Requirements

A PC with NetLinx Studio v4.0 or later installed.

An understanding of which DXLink Mode the system will be used in (see below and page 31). An understanding of the DIP switch settings (see page 36).

When used with an Enova DGX Digital Media Switcher the system’s power requirements must be determined (see page 31).

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 81).

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, binding to an integrated Master, 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 30).

Extender Mode (Standalone) – A standalone DXLink TX/RX pair are connected directly to each other as a simple extender solution (see page 31).

* 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 DX-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 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., Enova DGX 16), the cable runs from a Transmitter to a DXLink Input Board and from a DXLink Output Board to a Receiver can each be up to 328 feet (100 m).

Installation and Setup

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 64). For Enova DGX 8/16/32/64 Switchers, DGX Configuration Software can also be used to make scaling adjustments via the switcher (see the switcher’s manual). For Enova DGX 100 Series Switchers, scaling can also be adjusted via the System Configuration interface (see the switcher’s manual).

CAUTION: Be careful not to create a network (Ethernet) loop. To avoid doing so, see page 33.

Custom EDID Settings

If Transmitters are part of an Enova DGX system which requires custom EDID settings, see the switcher’s 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 64).

If Receivers are part of an Enova DGX 8/16/32/64 system which requires scaler control and settings, see the switcher’s manual for information on the scaling functionality in DGX Configuration Software (available at www.amx.com). SEND_COMMANDs can also be used (see page 64).
