DXF-4K Installation Guide
Overview
The DXF-4K optical extension kit transmits HDMI video resolutions up to Ultra High
Definition 4K video with HDR support to extend the reach of a limited-distance signal
medium (HDMI cable) to a much farther distance by using fiber optic cable. For this, it uses
a customer supplied OM41multimode fiber (MMF) to extend signal transmission to up to
1000m without any loss of signal integrity. This extension kit consists of a transmitter
module and a receiver module, power supplies, HDMI cables, and HDMI cable lock clips.
The DXF-4K-DVI kit includes a DVI to HDMI adapter for use with multiviewer models that
have a DVI mosaic output.
This installation manual describes how to install and use the DXF-4K optical extension kit.
Model Description
The following DXF-4K extension kit models are available.
See Unpacking, on page 3 for the kit contents.
Application
The supported application is to extend a Grass Valley video equipment’s HDMI output to a
display with an HDMI input by directly connecting the transmitter to the video source and
by connecting the receiver directly to the display. Both the transmitter and receiver must be
powered by an external power source such as an unused USB port or by a supplied wall
plug power supply.
1.NOTE: OM1, OM2, and OM3 fiber types are not supported.

DXF-4K Installation Guide
Using the DXF-4K with non-HDMI Multiviewer Outputs
The following figure shows the typical connections for DXF-4K kit.
Fig. 1-1: Typical DXF-4K kit application
Using the DXF-4K with non-HDMI Multiviewer Outputs
Certain Grass Valley multiviewers do not have HDMI mosaic outputs. However, the DXF-4K
optical extension system may still be used with the multiviewer by using a supported
adapter supplied by Grass Valley.
Supported Adapters
The following adapters have been tested with this solution.
• Display Port to HDMI adapter (sold with Kaleido-IP multiviewers)
• Quad link SDI to HDMI 2.0 converter (sold with 4K multiviewers)
• DVI to HDMI adapter, for use with a KXO-DUAL card, for example (sold as part of the
DXF-4K-DVI Kit)
The following figure shows the typical connections for DXF-4K-DVI kit or when a DXF-4K kit
is used with a supported adapter.

Installation Guide
Status Indicator Interpretation
Both the transmitter and receiver have a status indicator.
Fiber Optic Handling
Never assume a fiber is dark. Never look directly into the end of a fiber cable. All employees
in the area must wear laser safety glasses with side shields.
Installing connectors on a fiber requires special handling procedures. Read and follow the
fiber and connector manufacturer’s instructions.
Protect fiber cable ends and optical ports on equipment from dust and dirt.
• When a fiber cable is disconnected, fit a protective cap on the end.
• When no fiber cable is connected to an optical port, insert a protective cap.
Store unused protective caps in an airtight container to prevent the transfer of dust to the
fiber connectors when used in the future.
Installation
Use field-supplied OM4 Multimode Fiber (MMF) single fiber optical cable fitted with SC
connectors with this kit. For an installation overview, see Application, on page 1. Proceed as
follows:
1 Connect the optical cable to the DXF-4K receiver (RX6F-SH51-03A-BK): first remove the
protective cap from the receiver’s optical input port and then insert the optical cable
connector into the receiver’s optical input port.
Status Indicator Color Interpretation

Installation
2 Attach the HDMI cable lock sleeve to the receiver’s HDMI output cable.
3 Using an available surface screw, attach the HDMI cable lock strap to the display (for
example, the HDMI cable lock sleeve can be located anywhere along the HDMI cable’s
length and a VESA mount screw can be used to attach the HDMI cable lock strap to the
display).
4 Insert the HDMI cable lock strap into the HDMI cable lock sleeve and connect the
DXF-4K receiver output plug to the Display’s HDMI Input jack.
5Connectthemicro-USB B plug of the USB cable to the DXF-4K receiver’s power input
jack.
6 Power the DXF-4K receiver: connect the other end of the USB cable to a USB power
source such as an unused USB jack on the display or to the supplied power supply. If
used, plug-in the power supply to an outlet (mains).
7 Use a field-supplied tie-wrap to bundle up excess cable lengths. Do not fully tighten
the tie-wrap in order to not damage the optical cable by crushing or kinking the cable.
8 Connect the optical cable to the DXF-4K transmitter (TX6F-SH51-03A-BJK): first remove
the protective cap from the transmitter’s optical output port and then insert the optical
cable connector into the transmitter’s optical output port.

9 Attach the HDMI cable lock sleeve to the transmitter’s HDMI input cable.
10 Using an available surface screw, attach the HDMI cable lock strap to the display (for
example, use the screw found above most HDMI jacks).
11 Insert the HDMI cable lock strap into the HDMI cable lock sleeve.
12 Connect the DXF-4K transmitter input plug to the HDMI video source’s HDMI output
jack or to the adapter’s HDMI output jack (see Supported Adapters, on page 2).
13 When used, connect the adapter’s input plug to the video source’s output jack.
14 Power the DXF-4K transmitter: it may already be powered by the video source’s HDMI
connection; see if the transmitter’s status indicator is lit (see Status Indicator
Interpretation, on page 5). If the transmitter’s status indicator is not lit, connect the
micro-USB B plug of the USB cable to the DXF-4K transmitter’s power input jack and
connect the other end of the USB cable to a USB power source such as an unused USB
jack on the video source or to the supplied power supply. If used, plug-in the power
supply to an outlet (mains).
15 Use a field-supplied tie-wrap to attach the optical and USB cables to the rack frame if
possible. Do not fully tighten the tie-wrap in order to not damage the optical cable by
crushing or kinking the cable.
Configuration and Setup
The DXF-4K transmitter and receiver are ready to be used. They do not require any
configuration. See Status Indicator Interpretation, on page 5 to confirm the link’s
operational status.

Troubleshooting
Troubleshooting
Following a methodical process of elimination, try the following steps.
1 The Status Indicators on both DXF-4K transmitter and receiver show if they are
powered and these indicators provide troubleshooting information. See Status
Indicator Interpretation, on page 5.
2 If transmission stops unexpectedly and the transmitter is powered by the video
source’s HDMI connection, change the transmitter’s power source: connect the micro-
USB B plug of the USB cable to the DXF-4K transmitter’s power input jack and connect
the other end of the USB cable to a USB power source such as an unused USB jack on
the video source or to the supplied power supply. If used, plug-in the power supply to
an outlet (mains).
3 Make sure the fiber connectors are clean, as the problem is often related to dust
obstructing the light at the fiber connections.
4 Use another fiber connection.
5 Swap components of the DXF-4K kit with known working components, one
component at a time in a systematic fashion to further isolate the issue. For example,
swap the transmitter module, then swap the receiver module, and so on.
Firmware Upgrade
The firmware in the DXF-4K transmitter / receiver can be upgraded in the field. Only one
module can be upgraded at a time (transmitter or receiver). The following is required to
proceed:
• A Microsoft Windows PC that has:
• an available USB A port
• Internet connectivity
• Firmware image files; one for the transmitter module and one for the receiver module
• USB BootLoader firmware upgrade software
• USB cable, male USB A to male micro-USB B
Procedure to Connect to a Module
1UnziptheUSB BootLoader.zip file.
2 Double click the HIDBootloader vX.X.X.exe file to launch the USB BootLoader firmware
upgrade software.
3 Disconnect the optical fiber from the module.
4 Connect the micro-USB B plug of the USB cable to the DXF-4K receiver’s power input
jack and connect the other end of the USB cable to an available USB Port on your PC.
Note: Only one module may be connected to the PC at a time.
5 Wait for USB BootLoader’s connection confirmation. The receiver or transmitter module
should show solid Pink LED. The USB BootLoader Interface should have one of TX or RX
status buttons illuminated at the bottom of its Interface Window.
