Installation and Setup

Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
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 82).
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).
