DXLink™ Twisted Pair Transmitters/Receiver
Overview
The DXLink Multi-Format TX, HDMI TX, and DXLink HDMI RX Modules transmit
HDMI, audio, and control over twisted pair cable. The Multi-Format TX also has an
input for analog video. The DXLink Modules can be set up in one of three ways:
• Endpoint Mode (Switcher) – connect one or more to a switcher with an
integrated Master.
• Endpoint Mode (Standalone) – connect a pair directly to each other with one
connected to a NetLinx Central Controller via a LAN or directly to the Controller.
• Extender Mode (Standalone) – connect a pair directly to each other.
These Modules support InstaGate Pro® and SmartScale® Technology.
The Instruction Manual – DXLink Twisted Pair Transmitters/Receiver contains
complete documentation (including full specifications and supported input and output
resolutions); for details, see the AMX AutoPatch CD or visit www.amx.com.
General Specifications
* A desktop power supply (ENERGY STAR®qualified) is provided with each module.
System Setup
The Multi-Format TX or HDMI TX and the RX work with a switcher that supports
DXLink Technology for transmission of HDMI (or with a Central Controller) or as a
standalone pair. The Transmitter receives an HDMI signal (or analog video on a
Multi-Format TX) and embedded audio from the source. Both the video and embedded
audio are transported over twisted pair cable to a DXLink Input Board (or connector).
The signal is routed via the DXLink Output Board (or connector) to an RX. On both
Transmitters, stereo audio or digital audio connections are provided as supplemental
audio inputs. The RX also provides a stereo audio output. Both Transmitters and the
Receiver support RS-232 for serial data transfer, USB, IR, and Ethernet.
Important: When using DXLink Power from an Enova DGX Switcher or Enova DVX
Solution, we recommend wiring a technical ground from the TXs and RXs to the
enclosure. 1) On the rear of the DXLink Module, attach the ground wire to the
designated ground screw. 2) Connect the running end of the ground wire to a common
earthed ground (ideally, referenced to the switcher). If one DXLink unit is grounded,
remaining units connected to the same board on the switcher must also be grounded.

damage the DXLink equipment.
• TX / RX units can alternatively have power
supplied over twisted pair cable when connected
to DXLink power source, e.g., Enova DGX 16/32.
• When used in conjunction with the Enova DGX,
use the Enova DGX Configuration Tool located at
www.amx.com/enova to determine the power
requirements of a configuration and whether any
of the DXLink Transmitters or Receivers should
be powered with the local power. The tool
contains instructions on how to use it.

Supported Twisted Pair Cable Length
Important: DXlink twisted pair cable
runs for DXLink equipment should
only be run within a common
building.
Up to 328 ft. (100 m)
• Cable runs with a minimum specification of
ANSI/TIE/EIA 568A-5 and ratings of 250 MHz
or better may be used with DXLink equipment.
However, cable run topology and environmental
influences can affect the overall successful
distance capabilities of these runs. For successful
deployments up to 100 meters without
consideration to outside variables, AMX
recommends the use of shielded category cable
(STP) or Cat6A (or better) versions of unshielded
or shielded twisted pair (UTP/STP) for DXLink
runs. For more details and helpful cabling
information, please contact your AMX
representative for a copy of the white paper titled
“Cabling for Success with DXLink.”

Twisted Pair Cable Pinouts and RJ-45 LEDs
The DXLink and ICS LAN 10/100 ports both use twisted pair cable. FIG. 4 shows two
pinouts that can be used for either port. FIG. 5 shows the LEDs for each port.
Attaching Signal, Transport, and Control Cables
Important Cabling Considerations:
• Do not use the RJ-45 connector labeled “DXLink” for connecting to a standard
Ethernet Network. The connector is used for signal transport.
• Do not create a network (Ethernet) loop. A network loop is created when the
enclosure and one or more of its DXLink Modules are connected to a common
LAN (or a standalone pair when both endpoints connect to the same network).
• DXLink cable runs for DXLink equipment should be within a common building.
To attach signal, transport, and control cables to a Transmitter:
1. Set DIP switch toggles if necessary (for settings, see the previous page).
2. Multi-Format TX only – Attach HD-15 cable from source to Video In connector.
3. HDMI In – Attach an HDMI cable from the source to the HDMI In connector.*
4. DXLink connector – Attach a twisted pair cable to the DXLink output and to a
DXLink input connector on the switcher (or on the RX for a standalone pair).
5. Stereo Audio In jack (optional) – Insert analog audio cable from source into jack.
6. Digital Audio In jack (optional) – Insert a S/PDIF plug on the digital audio cable
from the source into the jack (see audio precedence table in next column).
7. ICS LAN10/100 port (optional) – Attach twisted pair cable from this port to LAN.
* DVI cable can be used via a cable adapter; however, advanced audio support from
HDMI will not be available.
To attach signal, transport, and control cables to the Receiver:
1. Set DIP switch toggles if necessary (for settings, see previous page).
2. DXLink input connector – Attach a twisted pair cable from the DXLink output
connector on the switcher (or on a TX) to the DXLink input.
3. HDMI Out – Attach HDMI cable from this port to the destination.
4. Stereo Audio Out jack (optional) – Connect an analog audio cable from this port
to the destination.
Applying Power
Caution: If a desktop power supply is used to power the unit, it must be the one
provided, which must not be altered in any way. Power can also come from PoE
injector PS-POE-AT-TC (FG423-84). AMX does not support use of any other power
supplies or PoE injectors, as they may potentially damage the DXLink equipment.
Local power takes precedence over DXLink power (via DXLink port) from switcher.
Important: If TXs/RXs are powered from an Enova DGX 16/32, use the Enova DGX
Configuration Tool on the AMX AutoPatch CD or at www.amx.com/enova.
To apply power to the Transmitter and Receiver:
1. Plug the cord from the desktop power supply (provided) into the power jack on
rear of the Transmitter (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 Transmitter illuminates green, indicating a ready state.
3. Repeat Steps 1 and 2 for the Receiver.
This table shows LED states on initial power up. If not normal, check connections.
* At power up, the RX defaults to Auto. Press the Scaling button to change the mode.
IP Addressing Modes
DHCP Mode (enabled when #3 Toggle is flipped ON)
In DHCP Mode, the Module attempts to get a DHCP lease (consisting of an
IP address, gateway, and other network parameters). If the attempt fails, the Module
configures itself for a link-local address, but periodically re-tries DHCP and re-assigns
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 and reconnect to the Master.
Static IP Mode (set with ID button or Telnet command)
With #3 Toggle set to ON, press ID for 10 seconds to assign address of 192.168.1.2
or use a Telnet command to set unit to Static IP Mode (see the Instruction Manual).
RS-232 Serial Data (Optional)
The 232 port label is relative to data flow. Data enters at the RX label on the
Transmitter, is sent via a DXLink cable through the switcher, and leaves at the
TX label on the Receiver. Flow is vice versa from the Receiver to the Transmitter.
The RS-232 pinout for all DXLink Modules is “TXD - RXD - Ground.”
To wire the 232 port for serial data transfer:
1. Wire the RS-232 connectors according to pinout above connectors.
IR Control (Optional)
The IR Receiver connects to the IR RX port on the Transmitter and the IR Emitter
connects to the IR TX port on the Receiver or vice versa, depending on the
installation. The signal is sent via DXLink cable through the switcher. When a
Transmitter and Receiver are used as a standalone pair, IR control acts as a
pass-through.
USB Host and Keyboard/Mouse Ports Provide HID Support (Rear)
These ports will be supported with a future firmware upgrade.
Program Port (Front)
This port will be supported with a future firmware upgrade.
ID Button (Front)
The ID button on the front can be used to toggle between static and DHCP IP
addressing, assign a device address, reset the factory defaults, and restore the
factory firmware image (for details, see the Instruction Manual).
