ESD Warning

Instruction Manual – DXLink Fiber Transmitters and Receivers
ESD Warning
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before
touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be
followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive
smocks, and conductive work mats are specifically designed for this purpose.
Anyone performing field maintenance on AMX DXLink Fiber equipment should use an appropriate ESD field service
kit complete with at least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another
ground cord. These items should not be manufactured locally, since they are generally composed of highly resistive
conductive materials to safely drain static charges, without increasing an electrocution risk in the event of an accident.
ESD protective equipment can be obtained from 3M™, Desco®, Richmond Technology®, Plastic Systems®, and other
such vendors.

DXLink Fiber Hardware Compatibility
This section applies to TX-to-RX standalone pairs and to DXLink Fiber Input or Output Boards and their corresponding
TX or RX units. (Duplex and Simplex boards can be used in the same enclosure.)
Connections are allowed between matching hardware (Duplex to Duplex or Simplex to Simplex) as well as between
mixed hardware (Simplex to Duplex or Duplex to Simplex) as long as the constraints of multimode to multimode and
single mode to single mode are maintained.
Important: Compatibility between hardware requires matching model types: multimode to multimode and
single mode to single mode.
The next section explains the functionality and limitations inherent in the three Directional Modes used for
communication control. An understanding of these modes is necessary, especially if you are not using the default for the
specific hardware type (Duplex or Simplex).
DXLink Fiber Directional Modes
DXLink Fiber Directional Modes include Bidirectional Mode, Unidirectional Mode, and Data Link-lost Mode. DXLink
Fiber, Duplex hardware has a default setting of Bidirectional Mode, but can be configured for Unidirectional Mode or
drop into Data Link-lost Mode (when the return path is removed or not connected). DXLink Fiber, Simplex hardware
only uses Unidirectional Mode.
Note: For instructions on setting Duplex TXs and RXs to a particular Directional Mode, see “Duplex Hardware
Directional Mode Configuration” on page 56. For instructions on configuring DXLink Fiber, Duplex Input and
Output Boards, see the “Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers.”
Bidirectional Mode
When data flows in two directions, the flow is bidirectional. For example, a source device sends audio, video, and
communication data to a TX. From the TX, all three signals are sent via fiber to an input board on the switcher. The input
board routes the audio and video to an output board, while the integrated Master processes the communication data. The
output board sends audio and video (along with any necessary communication data) via its RX to the destination device.
If needed, communication data from the destination device can return to the Master for processing via the same path.
Bidirectional is the default Directional Mode for DXLink Fiber, Duplex units if both fiber strands are connected. Setting
DIP switch #4 to ON enables Unidirectional Mode (see below) and the lack of a return fiber path results in the unit
dropping into Data Link-lost Mode (see below also).
Unidirectional Mode
When data flows in only one direction, the flow is unidirectional. For example, an audio/video signal travels from a
Transmitter to a Receiver and no signals are passed back to the Transmitter. In Unidirectional Mode, the Receiver does
not send an optical signal trying to establish a return data path connection. Simplex hardware always operates in this
mode and does not require additional setup. Unidirectional Mode is a configurable setting for Duplex hardware which
requires setting the DIP switch’s #4 Toggle on the bottom of the Transmitter or Receiver.
Data Link-lost Mode
When a system is configured for Bidirectional Mode, but the data return path has been removed or is not connected, the
system drops into Data Link-lost Mode. In Data Link-lost Mode, the Transmitter only sends audio and video to the
Receiver over a single fiber path, but both units are actively ready for the addition of the return path which will enable
Bidirectional Mode. For example, an audio/video signal travels from a Transmitter to a Receiver and no signals are
passed back to the Transmitter, but the Receiver’s return laser still transmits light and attempts to establish a connection.
Important: When using Duplex hardware in mixed modes (where boards and their units are configured for
different Directional Modes) or using both Duplex and Simplex hardware (where the Duplex hardware is in
Bidirectional Mode), the hardware must be configured to avoid Data Link-lost Mode (see Caution above).
Caution: In Data Link-lost Mode, the data return path is disconnected but both of the transceiver lasers are
still active. If left uncovered, transceiver lasers may constitute a health hazard. This hazard should be
avoided by restoring Bidirectional Mode (see page 56), configuring DXLink Fiber units for Unidirectional
Mode (see page 56), or covering exposed lasers.

Product Notes
Fiber Optic Transceivers
The DXLink Fiber units use SFP+ fiber optic transceivers*. Fiber optic transceivers are self-contained modules that send
and receive optical signals over fiber cable. These fiber optic transceivers are either multimode or single mode and must
be wired with the corresponding cable type.
* SFP+ = enhanced small form-factor pluggable fiber optic transceiver rated at 10 Gbps transmission data rate.
Note: The types of fiber optic transceivers used in DXLink Fiber units are referred to as “multimode” and
“single mode,” which indicate the maximum length of the fiber optic cable that can be used. In addition, the
Transmitters and Receivers support modes that can be determined during setup to handle the system
architecture, accommodate networking needs, and process video signals (see page 29).
Device Types / Cable Types / Cable Runs
The type of DXLink Fiber device determines the maximum length of cable runs possible. Cable quality is also a
determining factor.
All DXLink Fiber units are designed for transmission of an HDMI signal over fiber optic cable.
DXLink Fiber, Duplex multimode and single mode transceivers support bidirectional communication (Bidirectional
Mode) or unidirectional communication (Unidirectional and Data Link-lost Mode). DXLink Fiber, Simplex multimode
and single mode transceivers only support unidirectional communication.
Bidirectional Mode Communication
Bidirectional communication over DXLink Fiber includes transmission of digital video and audio, native NetLinx
control (IR and RS-232), USB keyboard and mouse, and Ethernet (100 Mbps).
Unidirectional Mode and Data Link-lost Mode Communication
Unidirectional and Data Link-lost communication over DXLink Fiber includes transmission of digital video and audio.
While native NetLinx control (IR and RS-232) is not supported over fiber, units can provide this support when they are
connected to a LAN via their ICS LAN 10/100 connector (see “Unidirectional Mode LAN Configuration” on page 60).

OSHA Directive
The OSHA Technical Manual (at https://www.osha.gov/dts/osta/otm/otm_iii/otm_iii_6.html) under “VI. Control
Measures and Safety Programs” states: “Direct exposure on the eye by a beam of laser light should always be avoided
with any laser, no matter how low the power.”
Transceiver Disposal
Important: If disposal of transceivers is necessary, dispose of them as mandated by your area or country
guidelines.
Multimode SFP+ Fiber Optic Transceiver
Multimode SFP+ fiber optic transceivers are used in the DXLink Fiber units specified in the table at the top of the
previous page. Depending on the transceiver model, it will have a latch that is black or a black label on the latch top with
white triangles showing data flow direction.
The multimode SFP+ fiber optic transceiver requires multimode fiber optic cable, which allows numerous optical waves
to traverse the optic core. Multimode fiber optic cable has a significantly larger optical core (which results in a higher
dispersion rate) and results in comparative shorter distance optical runs than the single mode cable.
Single Mode SFP+ Fiber Optic Transceiver
Single mode SFP+ fiber optic transceivers are used in the DXLink Fiber units specified in the table at the top of the
previous page. Depending on the transceiver model, it will have a bright blue latch or a blue label on the latch top with
white triangles showing data flow direction.
The single mode SFP+ fiber optic transceiver requires single mode fiber optic cable, which allows a single optical wave
to traverse through the optic core. Single mode fiber optic cable has a significantly smaller diameter optical core than
multimode fiber optic cable and is generally associated with longer distance transport capabilities.
Warning: DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive below).

Instruction Manual – DXLink Fiber Transmitters and Receivers
DXLink Fiber Multi-Format Transmitters
The DXLink Fiber Transmitters receive an HDMI signal or analog video signal (composite, Y/C, Y/Pb/Pr, RGB, RGBS,
or RGBHV) and an audio signal from a source device. The audio can be either digital audio embedded with the HDMI or
analog stereo audio.
Either analog or digital video is transmitted out of the fiber optic transceiver. The active video selection is made using
one of two methods:
Automatic – selects digital video as the priority video input or analog video when digital video is not present.
Can be set to treat either the digital or analog video as the priority, which then defaults to the opposite if the
primary is not present.
Active SEND_COMMAND video input selection from a bound NetLinx Central Controller (usually the
integrated Central Controller on the Enova DGX).
Both the video and audio are transported over fiber optic cable to either an Enova DGX Digital Media Switcher or
directly to a DXLink Fiber, Duplex RX. The unit also has a local HDMI output connector on the front for sending the
video signal from the source directly to a local destination device. This local HDMI output connection supports the same
input resolutions contained in the first table in “Appendix E - Supported Input Resolutions” (see page 130).
The 232 port (RS-232) on the Transmitters supports bidirectional serial data via the fiber optic cable to/from the
232 port. In addition, the Transmitters have IR ports, which also send data via the fiber optic cable.*
* Configuration of Ethernet, IR, RS-232, and USB for units in Unidirectional or Data Link-lost Mode requires additional
information found in “Unidirectional Mode LAN Configuration” on page 60.
DXLink Fiber HDMI Receivers
The DXLink Fiber Receivers feature SmartScale®Technology (integrated EDID output scaling) to ensure an appropriate
output resolution, plus they support a Manual (override) option for setting up custom resolutions and a Bypass option
(see page 61).
The DXLink Fiber Receivers receive an HDMI signal and an audio signal over fiber optic cable from a DXLink Fiber
Output Board on an Enova DGX Switcher or directly from a DXLink Fiber Transmitter. They then send the signal on to
the destination. The audio output can be either digital audio embedded with the HDMI signal or analog stereo audio (if
the signal originated as a 2 channel audio format).
The 232 ports (RS-232) support bidirectional serial data via the fiber optic cable, which connects the DXLink Fiber
TX/RX units with the Enova DGX Switcher or with the DXLink Fiber Transmitter.*
* Configuration of Ethernet, IR, RS-232, and USB for units in Unidirectional or Data Link-lost Mode requires additional
information found in “Unidirectional Mode LAN Configuration” on page 60.
Note: If a DVI-D signal is used (via a DVI-to-HDMI cable), the advanced audio support from HDMI will not be
available out the Receiver.
Note: DXLink Fiber units support several different modes which are available for system setup and use. Brief
explanations of the modes are provided in the section “Quick Reference Tables for Modes” on page 29 along
with page references to detailed information.

Common Applications
DXLink Fiber Transmitters and Receivers, Duplex and Simplex are ideal for any sources and destinations designed into
Enova DGX integrated systems that require the distance capabilities and/or inherent security of fiber with bidirectional
or unidirectional data transfer. These transmitters and receivers easily handle campus-wide distribution of sources that
are shared between classrooms, in secure military applications, medical facilities, casinos, arenas, museums, and large
corporate installations. Connect digital or analog video sources to the TXs directly using the HDMI or HD-15
multi-format input connection and easily include audio on the same fiber optic cable by using the stereo or digital audio
connection. Directly connect LCDs, plasmas, and projectors to the RXs using the HDMI output connection while
delivering room audio via the stereo audio output.
The installation’s requirements dictate the system setup, which generally takes one of the following three forms.
Endpoint Mode (Switcher) – One or more TX and/or RX are connected to a switcher containing an
integrated Master (see page 40).
Endpoint Mode (Standalone) – A standalone 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 42).
Extender Mode (Standalone) – A standalone TX/RX pair are connected directly to each other as a simple
extender solution (see page 42).

Instruction Manual – DXLink Fiber Transmitters and Receivers
DXLink Fiber Transmitters
DXLink Fiber Transmitters differ in the type of fiber optic transceiver they employ and the Directional Mode they use by
default. Duplex Transmitters default to providing simultaneous, bidirectional data transfer or can be configured to
provide unidirectional data transfer. Simplex Transmitters are designed to only provide a single direction of data flow
and not receive return data flow. The DXF-TX-MMD and DXF-TX-MMS have a multimode transceiver (the latch is
black or has a black label), and the DXF-TX-SMD and DXF-TX-SMS have a single mode fiber optic transceiver (the
latch is blue or has a blue label).
Note: A DVI-D signal can be used (via a DVI-to-HDMI cable) into the Transmitter.
