Hardware Reference Manual – DXLink™ Twisted Pair 4K Transmitters/Receivers
Setup Information
IMPORTANT:
The setup information in this manual applies to TXs and RXs 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), DXLink equipment is
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”).
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 23).
An understanding of the DIP switch settings (see page 27).
When used with an Enova DGX Digital Media Switcher the system’s power requirements must be determined (see page 23).
When used with a Solecis 4K Digital Switcher – consult the switcher’s Hardware Reference Manual at www.amx.com.
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).
The specific installation’s requirements dictate the system setup, which generally takes one of the following three forms.
Endpoint Mode (Switcher) – One or more TXs and/or RXs connected to a switcher containing a Master (see below).
Endpoint Mode (Standalone) – Standalone DXLink TX/RX pair connected directly to each other but, in addition, the RX is
connected to a NetLinx Central Controller via a LAN or directly to the Controller (see page 22).
Extender Mode (Standalone) – Standalone DXLink TX/RX connected directly as a simple extender solution (see page 23).
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).
The Transmitter receives an HDMI signal with a digital audio signal embedded with the HDMI signal from a source device. 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 800), 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 262 feet (80 m).
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 47). 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 24.
