1.0 Introduction
The Hall Research FXT-460 is a compact and high-performance extender for full-
bandwidth HDMI 2.0 audio/video with HDR, up to 10 Kilometers, over a single strand of
LC-terminated fiber-optic cable. The product supports 18.2 Gbps of bandwidth and 600
MHz TMDS Clock frequency and can extend 4K 60 Hz video with multi-channel audio
and RS232.
The system provides advanced capabilities such as embedding and de-embedding
audio, 4K UHD video (4:4:4 with HDR), HDCP 2.0, bidirectional RS-232 and EDID
management.
The FXT-460-S Sender provides an HDMI input with a corresponding HDMI loop output.
The audio component of the HDMI input is extracted and available as both analog (L/R)
and Digital SPDIF (TOSLINK) on corresponding connectors (see diagram above).

The audio that is embedded in the extended HDMI to the remote Receiver can be
selected by the user to be one of the following:
 Pass-through from HDMI input (same audio content as the HDMI input)
 External analog audio from the 3.5mm audio input connector
 External digital SPDIF audio from the Optical TOSLINK input connector
EDID management allows users to control the video and audio parts of the EDID
independently. The EDID presented to the source connected to the HDMI input can pass
from the downstream device or emulated from internal memory. The device can also
“Learn” the EDID connected to its HDMI output.
The product has a video bandwidth of 18 Gbps and supports input resolutions of up to 4K
@ 60 Hz 4:4:4 with HDR. It supports HDCP 2.2 as well as HDCP 1.4. All resolutions up
to and including 4K @ 30Hz with 4:4:4 or 4K @ 60 Hz with 4:2:0 are extended with no
compression.
The device has the ability to generate a blank HDMI output signal with audio embedded
even if there is no HDMI input; often referred to as “HDMI Audio Bridging”. This is a
convenient means to distribute audio only signals over an HDMI network.
Features
 4K x 2K @ 60 Hz 4:4:4 / 18.2 Gbps / HDCP 2.2
 Extends up to 33,000 ft (10 Km) over single mode or 1000 ft (300 M) Multi-Mode
 Bi-Directional RS-232 and EDID Management
 Can pass original HDMI audio or embed/substitute audio from external inputs
 "HDMI Audio Bridging"
 HDMI Loop Output on Sender
 De-embedded HDMI audio available at both ends (Sender and Receiver)
 EDID Emulation with LEARN function

3.0 Setup
Installation
 On both the FXT-460-S and FXT-460-R, make sure the SFP modules are fully
inserted as they could have become disconnected during shipping.
 Interconnect the FXT-460-S and FXT-460-R with an LC®/PC fiber optic cable.
 Optionally, Connect the RS-232 TX, RX and GND contacts to compatible
controllers (e.g., PC or RS-232 controller).
o Direction of data flow is shown in section below.
o RS-232 passes bi-directionally between the FXT-460-S and FXT-460-R at
115200 baud only.
 FXT-460-S
o Optionally, Connect an HDMI source to the HDMI IN connector and if desired a
HDMI compatible sink to the HDMI OUT connector.

o Optionally, for audio extraction at the transmitter
 Connect the SPDIF OUT and/or L/R OUT audio outputs to a compatible
audio device. (e.g., headphones, assistive listening devices, or Audio
Amplifier such as the Hall Research AMP-4840 or AMP-7040).
o Optionally, if you don't want to extend the original HDMI audio
 Connect the audio to embed to the SPDIF IN and/or L/R IN connector(s).

 FXT-460-R
NOTE A video source is NOT required to embed audio onto
the HDMI output at the FXT-460-R. If no HDMI source
signal is present, the HDMI Output at the FXT-460-R
will be a black screen at 480p resolution.
NOTE Hall Research can provide pre-terminated LC fiber
optical cable at custom lengths. You can use single
mode or multimode fiber optic cable. Single mode
fiber is recommended due to its 10 km range

EDID Handling
With no SINK attached to the FXT-460-R HDMI OUT connector, the EDID presented to
the SOURCE will be emulated from the current EDID stored in the system.
5.0 Troubleshooting
If you are experiencing problems getting the system to work properly, please use the
following troubleshooting suggestions.
 Ensure that all connections to the device are solid. Loose connections are the
number one cause of issues.
 Try resetting the system by unplugging both power supplies and the HDMI IN
connector, wait 5 seconds and plug everything back in.
o The front panel LEDs cycle several times at power up; after ~15
seconds, audio and video should be passing through the device.
 Try restoring factory defaults using the front panel VIDEO EDID button (hold for
7 seconds).
 Cycle the EDID mode with the front panel VIDEO EDID button.

