Introduction
Overview
The Transmitters and Receiver are designed for transmission of an HDMI signal over twisted pair cable up
to 328 feet (100 m). Functionality is briefly described below.
DX-TX-4K60
The DX-TX-4K60 is an HDMI transmitter with 4K@60Hz 4:4:4 and HDCP 2.2 compatibly. It receives an
HDMI signal and an audio signal from a source device. The audio can be either digital audio embedded
with the HDMI, or analog stereo audio. Both the video and audio are transported over twisted pair cable to
an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution, or directly to a DX-RX-4K60.
The RS-232 port on a DX-TX-4K60 supports bidirectional serial data via the twisted pair cable to/from the
RS-232 port on a DX-RX-4K60. The IR TX and IR RX ports on a DX-TX-4K60 each support unidirectional
IR data via the twisted pair cable to/from the IR RX and IR TX ports on a DX-RX-4K60. The USB Host /
Device ports on a DX-TX-4K60 support transmitting USB data via the twisted pair cable to/from a DX-RX-
4K60. It can be controlled through sending ICSP commands from a NetLinx Central Controller and also
supports CEC control and pass through to control the 3rd-Party devices.
DX-RX-4K60
The DX-RX-4K60 is an HDMI receiver with 4K@60Hz 4:4:4 and HDCP 2.2 compatibly. It receives an HDMI
signal with embedded audio over twisted pair cable from an Enova DGX Digital Media Switcher, an
applicable Enova DVX Solution, or directly from a DX-TX-4K60. The RS-232 port on a DX-T=RX-4K60
supports bidirectional serial data via the twisted pair cable to/from the RS-232 port on a DX-TX-4K60. The
IR TX and IR RX ports on a DX-RX-4K60 each support unidirectional IR data via the twisted pair cable
to/from the IR RX and IR TX ports on a DX-TX-4K60. The USB Host and Device ports on a DX-RX-4K60

Pinout Information
RS232
Connects to a RS232 device with the 3-pole, 3.5mm captive screw connectors. Wire as shown below:
Twisted Pair cable
The pinout in the following picture is for twisted pair cable that connects to the ICS LAN 10/100 connector (on
modules only) or to the DXLink connector on all Transmitters and Receivers. Use either the T568A or T568B pinout
specification for termination of the twisted pair cable used between the units in a standalone setup or between
Transmitters and Receivers and an enclosure in a full system.
In a typical installation, the cables should be stretched to their full length between Transmitters and Receivers and
the enclosure or between units in a standalone system. Service loops or coils of the cable may reduce the overall
cable performance and should be minimized whenever possible.

Quick Reference Tables for Modes
The modes listed in the following three tables are those supported by DXLink Transmitters and Receivers. The Quick
Reference Tables are intended to help users navigate the many modes available for system setup and use. For
complete information on any of the modes listed, see the relevant sections or chapter referenced at the end of the
Descriptions.
Quick Reference Table - Modes for Handling System Architecture
Mode Description
DXLink Modes DXLink Modes refer to the type of physical components and how they are connected
to make up the system. When Transmitters and Receivers are cabled into a system
and powered on, they automatically detect the DXLink Mode they are being used in.
Endpoint Mode:
When the system is setup to use Transmitters and/or Receivers with an Enova
DGX Digital Media Switcher or an applicable Enova DVX Solution, the system is in
Endpoint Mode.
Or
When a TX is directly connected to an RX but, in addition, the TX and/or RX is
connected to a NetLinx Central Controller via a LAN or directly connected to the
Controller, the system is in Endpoint Mode.
Extender Mode:
When a TX is directly connected to an RX, the system is in Extender Mode.
For further information, reference #2 Toggle DIP switch settings for DXLink Mode and
DXLink System SEND_COMMANDs.
Quick Reference Table - Modes for Handling Addressing/Networking
Mode Description
IP Addressing
Modes
IP Addressing Modes refer to network connection settings. By default, all network
connection settings are turned OFF.
Static IP Mode:
This mode configures the network connection to one stable IP address the device
will use continuously.
DHCP Mode:
This mode configures the network connection to choose a new IP address for
each network session.
Change IP Addressing Modes, send commands through NetLinx (see “APPENDIX C:
ICSP Commands”), press ID Pushbutton or set on the web UI.
ID Mode ID (Identify) Mode refers to the protocol for enabling a user to establish device
addresses. This Mode, accessible through NetLinx Studio, places the entire system on
hold while it waits for an event from a NetLinx device in the named system (e.g.,
pressing the ID Pushbutton on the TX or RX). For further information, see “Assign a
Device Address (ID Mode)” part of “DIP Switch Function” section.
Ethernet Modes
Ethernet Modes refer to the LAN configuration settings.
Auto Mode:
This mode configures the LAN driver to discover its own settings based on the
network it is connected to.

Quick Reference Table - Modes for Handling Addressing/Networking
Mode Description
Ethernet Modes
(continued)
Speed/Duplex Mode:
This mode configures the LAN driver to calculate its speed as either 10 or 100
and to communicate in either half- or full-duplex.
Ethernet Mode discovery and configuration information is available through
Telnet commands.
Change or get Ethernet Modes, send Telnet commands, see the “APPENDIX C: ICSP
Commands” section.
Central Controller
Connection
Modes
Central Controller Connection Modes refer to the modes of communication used for
connection to the Central Controller as specified via the SET CONNECTION Telnet
command and web UI.
Auto Mode:
This mode utilizes TCP communication. It looks for a matching System Number and
attempts to come online with the first Central Controller it sees with that System
Number.
TCP URL Mode:
TCP; the Central Controller is specified via URL.
UDP URL Mode:
UDP; the Central Controller is specified via URL.
NDP Mode (Default):
UDP; utilizes the NDP binding process to assign the DXLink Module (the physical
device) to a Central Controller (or Virtual Central Controller) via NetLinx Studio. Once
bound, communications are conducted via UDP.
Auto-setup Mode In auto-setup mode, endpoints are automatically discovered by and connected to an
Enova DGX 100 Series
Switcher using a single IP address. For this mode, all of the following requirements
must be met. If not, the endpoint will no longer reside in auto-setup mode and must
be either bound to the integrated Central Controller or reconfigured to meet the
requirements.
Endpoint must be connected to a DXLink Input Board in an Enova DGX 100 Series
Switcher (or Enova DGX with upgraded 100 Series CPU).
Endpoint must have IP mode set to DHCP for setup (self-configures to Static IP
on private LAN).
Endpoint must have the Central Controller connection type set to NDP.
Endpoint must not be bound to a Central Controller via NDP (traditional binding
process).
Endpoint DIP switch setting for Toggle #3 (network connectivity) is ignored while
in auto-setup mode
IMPORTANT: If auto-setup is being used, Telnet is the only way to access some of the
network settings. Also note that some network settings will disable auto-setup.
For additional information on the auto-setup feature, see “the Hardware Reference
Manual – Enova DGX 100 Series Digital Media Switchers”.

Quick Reference Table - Modes for Handling Video Processing
Mode Description
Scaling Scaling Modes refer to how the system alters or maintains a source device’s resolution
as it is passed along to the destination device. The Scaling Mode can be set through
RX Web UI, with SEND_COMMANDs, or through DGX Configuration Software when
scaling is being done via an Enova DXLink Output Board.
Auto Mode (Default):
Auto Mode (SmartScale®) allows the destination device to choose the resolution
it needs.
Manual Mode:
Manual Mode allows the user to configure the resolution the video will display
through a destination device.
Bypass Mode:
Bypass Mode allows the video signal to display over the destination device without
altering the signal’s resolution.

DIP Switch Function
The DIP Switch is located on the front panel of DX-TX-4K60 and DX-RX-4K60, the functions is descripted as follows.
#1 Toggle is used for enabling/disabling the physical ICS LAN 10/100 port.
#2 Toggle is used for setting Modules to either automatically or manually determine the DXLink Mode.
#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).
# 4 Toggle is not functional.
#1 Toggle Settings
Setting DIP Switch #1 to Enable/Disable Access to LAN 10/100 Port.
OFF (Default): When the #1 Toggle is set to OFF, network activity over the ICS LAN 10/100 port is disabled.
ON: When the #1 Toggle is set to ON, network activity over the ICS LAN 10/100 port is enabled.
Installation Options:
Option A: For a network connection between a Transmitter and a Receiver where only one of them is
connected to a LAN, set the #1 Toggle to ON for the unit that is connected to the network.
Note: Option A – Do not connect both the Transmitter and the Receiver to a common LAN as a network loop will result.
Option B: When a Transmitter or Receiver is connected to a DXLink input or output on an Enova DGX Digital
Media Switcher or Enova DVX switcher, the switcher provides a network connection allowing the Transmitter
or Receiver to appear in the online tree in NetLinx Studio (#3 Toggle must be set to ON). For connecting the
Transmitter or Receiver to other equipment using the ICS LAN 10/100 port, the #1 Toggle must be set to
ON.
Note: Option B: Because the DXLink connection carries network activity passed from the switcher, do not connect the
ICS LAN 10/100 port on the Transmitter or Receiver to the same LAN as the switcher because a network loop will
result.
#2 Toggle Settings
#2 Toggle can be set to automatically or manually select the DXLink Mode (to either Extender or Endpoint) for a
given Transmitter/Receiver Module. Default state for #2 Toggle OFF is auto selection of DXLink Mode based on
connection to another device. When it’s ON, the default is Endpoint Mode (used for Central Controller controlled
serial/IR data transfer).
OFF (Default): When #2 Toggle is set to OFF, the Transmitter and Receiver will each auto-discover* what

type of DXLink equipment they are connected to and will automatically self-configure to be in one of two
DXLink Modes based on the connection:
Extender Mode – This mode is automatically selected when a TX and RX are connected directly to each other (a
standalone pair). The Transmitter and Receiver act like a simple extender, and serial and IR data is passed through
them.
Endpoint Mode – This mode is automatically selected when a module is connected directly to a DXLink port on a
switcher. Serial and IR operations are handled by the host providing control of endpoints. The Central Controller’s
programming specifies where IR and serial commands are sent (this is handled independently from the routing of
the video signals).
* Any time the DXLink connection is re-established or power is cycled on a module, the auto-discovery process will
take place, as long as the #2 Toggle remains in the OFF position.
ON: When #2 Toggle is set to ON, the auto-discover feature is disabled and the module can be manually set
to either Endpoint Mode (default) or Extender Mode. In Endpoint Mode, when the module is connected to a
switcher or a separate NetLinx Central Controller **, IR and serial operation are only handled via the host.
** When standalone modules require IR and/or Serial control by a separate NetLinx Central Controller, then they
need to be in Endpoint Mode. Only one must be connected via the ICS LAN 10/100 port to the Central Controller or
to a LAN with the Central Controller on it. This requires #1 Toggle to be ON to enable the ICS LAN port. #2 Toggle
needs to be ON to place the modules in Endpoint Mode (if needed), and #3 Toggle needs to be ON to enable network
connectivity.
Note: On either setting, the DXLink Mode may be set via SEND_COMMANDs (see “APPENDIX C: ICSP Commands”
section). When #2 Toggle is set to the OFF position, the auto-discovery process will overwrite the DXLink Mode setting.
However, when the #2 Toggle is set to the ON position, auto-discovery is disabled and the mode set by
SEND_COMMANDs will persist (i.e., the DXLink Mode setting cannot be overwritten).
Setting DIP Switch #3 for Network Connectivity, default setting is OFF, the transmitter and receiver will not
try to connect to the network and will not acquire an IP address;
Setting DIP Switch #4 is Reserved.
Note:
For easiest access to the DIP switch toggles, we recommend setting them before installation.
DIP switch settings on any of these DXLink products are read only on reboot. After the settings are read, any
adjustments of the toggles will not be implemented and will not affect the system.
#3 Toggle Settings
The #3 Toggle is used for enabling/disabling network connectivity (IP addressing) of the DXLink Transmitter or
Receiver. If enabled, it allows the Transmitter or Receiver to be configured to connect to a NetLinx Central Controller
(used for controlling the DXLink unit and allowing Ethernet traffic).
OFF (default) – When the #3 Toggle is set to OFF, the Transmitter or Receiver will not try to connect to the
network and will not acquire an IP address.
ON – When the #3 Toggle is set to ON, the Transmitter or Receiver will attempt to connect to the network
via DHCP or static IP, depending on how the unit has been set up. The Transmitter and Receiver will not
display in NetLinx Studio and will not accept commands or queries unless the #3 Toggle is ON.
Note: After the #3 Toggle is set to ON, a network connection is established, and the NetLinx Studio screen is refreshed,
Transmitters and Receivers display in the Online Tree as Unbound NDP (Network Detect Proxy) Devices. To facilitate
IRL and KIT file transfers, they can be bound to the integrated NetLinx Central Controller in a switcher or to another
NetLinx Central Controller. A Virtual NetLinx Central Controller can also be used for file transfers.
