QUICK START GUIDE

DXLink™ Twisted Pair Transmitter/Receiver

Overview

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 more to a switcher with an integrated

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 Mode (Standalone) – connect TX/RX pair directly to each other.

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

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 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.

DIP Switch Toggles – Default OFF (for Auto-setup, see next page)

Before installing the units, find the scenario you are using in the table below and set the

DIP switch toggles accordingly. Toggle #4 is reserved for future functionality.

For standalone pair upgrades, set Toggles #1-2-3 to ON and connect one unit to Master.

* Connect ICS LAN port of DXLink unit to network device (e.g., laptop, IP controlled

projector, ICSLan Device). In standalone setup, connect ICS LAN port of other DXLink

unit to network.

** In standalone setup using NetLinx control of DXLink serial/IR ports, only one of the

DXLink units should be connected to network (the unit with #1 Toggle enabled).

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 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 the Hardware Reference Manual – DXLink

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

representative.

Grounding

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. 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.
