DXLink Port

ICS LAN 10/100 Port

The DXLink Multi-Format TX and HDMI RX Modules transmit HDMI, audio, and control
over twisted pair cable. The TX also has an analog video input. DXLink Modules can be
set up in one of three ways:

• Endpoint Mode (Switcher) – connect one or mo re to a switcher with an in tegrated
Master.

• Endpoint Mode (Standalone) – connect TX/RX pair directly to each other with one
connected to a NetLinx Central Controller via LAN or directly to Controller.

• Extender M ode (St andalone) – connec t TX /R X pair directl y to ea ch ot her.

These Modules support InstaGate Pro® and SmartScale® Technology.
The Hardware Reference Manual – DXLink Twisted Pair Transmitters/Receiver contains

complete documentation (including full specifications and supported input and output
resolutions); for details, see www.amx.com

.

System Setup

The Multi-Format TX and the RX work with a switcher that supports DXLink Technology
for transmission of HDMI (or with a Central Controller) or as a stand-alone pair. The
Transmitter receives an HDMI signal (or analog video on a Multi-Format TX) and
emb edded au dio fro m t he sou rce . Bot h t he vide o and e mbedded au dio are t ransp or ted
over twisted pair cable to a DXLink Input Board (or connector). The signal is routed via
the DXLink Outpu t Board (or connector) to an RX. On the Transmitter, stereo audio or
digital audio connections are provided as supplemental audio inputs. The RX also
provides a stereo audio output. Both the Transmitter and the Receiver support RS-232
for serial data transfer, USB, IR, and Ethernet.

Mounting Options (Rack Trays and Mounting Brackets)

For details on the four versatile mounting kit options for V Style modules (rack tray, rack
tray with fill plates, surface mount, and pole mount), see www.amx.com

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

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 Twisted Pair Cabling Requirements and Recommendations:

• 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 (RJ-45) connectors must not be used 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 delivers 10.2 Gb/s throughpu t 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 the Hardware Refere nce Manual – DX Link
Twisted Pair Transmitters/Receiver.

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

“Cabling for Success with DXLink” available at www.amx.com

Grounding

If the system is experiencing problems with delivery o f 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. 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
(for instructions, see the product manual).

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

Applying Power

A desktop power supply is provided with each module. Power can be supplied to DXLink
Twisted Pair Modules by DXLink Power sourcing devices as follows:

• To a TX or RX module from an Enova DGX Switcher or PS-POE-AT-TC (FG423-84)
or PDXL-2 (FG1090-170).*

• To a TX module from a DVX-3156HD, DVX-3155HD, or DVX-2155HD.

• To an RX module from a DVX-2155HD, DVX-2150HD, or an SDX-501M-DX.

Power Budget: For TXs and/or RXs connected to an Enova DGX, use the Enova DGX
Configuration Tool (www.amx.com/enova) to determine power requirements of a
configuration and if any DXLink TXs or RXs should use the local power. The tool
contains instructions on how to use it.

* To use PS-POE-AT-TC or PDXL-2 as a power source, the TX requires firmware v1.2.40
(or later) and the RX v1.0.80 (or later).

NOTE: Local power takes precedence over DXLink power (via DXLink port) from switcher.
IMPORTANT: If a desktop power supply is used to power the unit, it must

provided, which must not be altered in any way. AMX does not support use of any other

be the one

power supplies or PoE injectors as they may potentially damage the DXLink equipment.

To apply power to the Transmitter (or Receiver):

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

2. Plug the desktop power supply into an AC external power source. The Power LED
on the front of the TX (or RX) illuminates green, indicating a ready state.

This table shows LED states on initial power up. If not normal, check connections.

DXLink Auto-setup with Enova DGX 100 Series Switchers

Auto-setup is the default for using DXLink Modules with Enova DGX 100 Series
Switchers. When all of the following conditions are met, the modules automatically go
into Auto-setup Mode and can communicate through the ICS LAN port with the
integrated Master via Telnet:

• Endpoints must be set to DHCP Mode (default) and use the NDP Master
connection mode (default).

• Endpoints must not be bound to a Master.

IMPORTANT: On the switcher, the ICS LAN port acts as a DHCP server (private LAN) and
the LAN 100/1000 port acts as a DHCP client (public LAN) with each port on a separate
network. In order to avoid a Network Loop, do not connect any device on the private
network to any branch on the public network.

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 manual).

Enova DGX/DVX and DXLink IP Setup (systems without auto-setup)

The following procedure is intended to outline the steps necessary for network setup of
DXLink Twisted Pair TX and/or RX with an Enova DGX 8/16/32/64 or Enova DVX
switcher. These steps require familiarity with NetLinx Studio. If unfamiliar with NetLinx
Studio, complete instructions are included in the Hardware Reference Manual – DXLink
Twisted Pair Transmitters/Receiver.

To setup DXLink Module(s) with an Enova DGX 8/16/32/64 or Enova DVX:

1. Set the DIP switches on the DXLink Module(s).

2. Apply power to the DXLink Module(s).

3. Connect DXLink Module(s) to the Enova DGX or Enova DVX.

4. Optional – Conf igure a Static IP address (for each connected Module).

5. Conf igure the Device ID (for each connected Module).

6. Connect (Bind ) the DXLink Module(s) to the Enova DGX or Enova DVX.

RS-232 Serial Data (Optional)

The 232 port label is relative to data flow. Data enters at RX label on the Transmitter, is
sent via a DXLink cable through the switcher, and leaves at TX label on Receiver. Flow is
vice versa from Receiver to Transmitter. Applies to all DXLink modules – wire RS-232
port for serial data transfer according to pinout above connectors (TXD-RXD-Ground).

IR Control (Optional)

The IR Receiver (FG-IR03) connects to the IR RX port on the Transmitter and the
IR Emitter (FG10-000-11) 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
passthrough.

USB Host and Keyboard/Mouse Ports (Rear)

If needed, the Host (USB-B) port on the TX and the K/M port (USB-A) on the RX provide
HID support for a keyboard, mouse, and HUB. For a list of supported HID devices
(keyboards and mice), see the Receiver’s product page at www.amx.com

.

Program Port (Front)

This USB mini-B port on the Transmitter supports DGX Configuration Software for
programming a customer VGA EDID (for modules connected to an Enova DGX 100
Series Switcher, use the System Configuration interface; see the switcher’s manual).

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 manual).
