Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver
NOTE:
The DX-RX can also be powered through the DXLink connector when it is attached to a DXLink Output Board in an Enova
DGX Switcher. We recommend calculating the power budget for the switcher to maintain the redundancy of its power supplies
(see page 31).
Ground Screw
– The ground screw is for creating a technical ground for the ungrounded sources/destinations with respect
to the DXLink Transmitters/Receivers and switcher (see page 37).
DXLink Input Connector
– The DXLink (RJ-45) connectors transport digital video, embedded audio, Ethernet, and
bidirectional control over twisted pair cable to DXLink devices or boards, including digitally transcoded analog video signals.
The DXLink path supports HDCP and also supports power over the same path from an Enova DGX Switcher and from some
Enova DVX Solutions to power the module. For pinout and LED information, see page 39.
ICS LAN 10/100 Connecto
r – The ICS LAN 10/100 (RJ-45) connector is for Ethernet 10/100 connectivity (e.g., receiving
SEND_COMMAND commands and downloading firmware update files). For pinout and LED information, see page 39.
RS-232 Port
– The RS-232 (serial data interface) port is a 3-position screw block which accepts data from the source
device and transfers it via the twisted pair cable to the DX-RX, which in turn transfers the data to the destination device or
the transfer of data can also be made from the destination to the source. In addition to being directly connected to a device,
this port can be connected as an independent native NetLinx control port from a networked NetLinx Central Controller.
IR RX Port
– The IR RX port is used for IR control (see page 19). This port is a 3.5 mm stereo jack. In addition to being
directly connected to a device, this port can be connected as an independent native NetLinx control port from a networked
NetLinx Central Controller.
IR TX Port
– The IR TX port is used for IR control (see page 19). This port is a 2-way mini-Phoenix connector. In addition to
being directly connected to a device, this port can be connected as an independent native NetLinx control port from a
networked NetLinx Central Controller.
USB Port
– The USB-A port on the RX supports keyboard/mouse. This port is used in conjunction with the USB-B Host port
on the HDMI TX which supports a USB device and connects to the PC. (For USB port information, see page 18.)
HDMI Out Connector
– The HDMI Out connector is for digital video and embedded audio. The HDMI connector has a center
screw for locking capability. The HDMI connector also supports a DVI-D signal (a DVI-to-HDMI cable adapter is required).
Stereo Audio Out Connector
– The Stereo Audio Out connector is a 3.5 mm stereo jack. This connector has an analog audio
signal available for output whether the embedded audio over the DXLink cable originated as 2 channel digital or analog
stereo. If encoded digital audio (e.g., Dolby or DTS) or multi-channel audio paths (>2 CH L-PCM) are embedded on the
HDMI path, then this local analog port out will not be available.
Common Features/Functionality
This section covers the DIP switches, the USB port, HDCP compliance, and IR functionality.
DIP Switches
TIP:
For easiest access to the DIP switch toggles, we recommend setting them before installation.
A four-toggle DIP switch is on the bottom of the DXLink Modules, on the rear of the Wallplate TX, and on the front of the Decor
Wallplate TX (the front can be covered with a customer provided standard decor style front cover plate).
#1 Toggle is used for enabling/disabling the physical ICS LAN 10/100 port (see page 34).
#2 Toggle is used for setting the DXLink Modules to either automatically or manually determine the DXLink Mode (see
page 35).
#3 Toggle is used for enabling/disabling network connectivity of the DXLink Transmitter or Receiver to a connected NetLinx
Central Controller (used for IR ports, serial ports, and commands to the DXLink unit); see page 35.
#4 Toggle is not functional.
NOTE:
The mounting bracket on the Wallplate TX must be removed (unscrew the four screws from the bracket and set it aside) before
the DIP switch toggles can be set.
