Introduction
OVERVIEW
The Hall Technologies 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 a 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
Package Contents
FXT-460-S & FXT-460-R
- 1x Model FXT-460-S
- 1x 3 position terminal block for RS-232

Setup
INSTALLATION
-
On both the FXT-460-S and the 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.
*Note: Hall Technologies 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. -
Optionally, Connect the RS-232 TX, RX, and GND contacts to compatible controllers (e.g., PC or RS-232 controller).
– Direction of data flow is shown in section below.
– RS-232 passes bi-directionally between the FXT-460-S and FXT-460-R at 115200 baud only.
FXT-460-S
-
Optionally, connect an HDMI source to the HDMI IN connector and if desired a HDMI compatible sink to the HDMI OUT connector.
*Note: A video source is NOT required to embed audio onto the HDMI output at the FXT-460-R.
If no HMDI source signal is present, the HDMI output at the FXT-460-R will be a black screen at 480p resolution. -
Optionally, for audio extraction at 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 Technologies AMP-4840 or AMP-7040.) -
Optionally, if you don’t want to extend the original HMDI audio:
– Connect the audio to embed to the SPDIF IN and/or L/R IN connector(s).
FXT-460-R
-
Optionally, connect an HDMI compatible sink to the HDMI OUT connector.
*Note: A video sink is NOT required to extract audio. -
Optionally, for audio extraction at 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 Technologies AMP-4840 or AMP-7040.) -
Connect the included power supplies to the 12V DC connectors on both the FXT-460-S and FXT460-R.

presented to the SOURCE will be emulated from the current EDID stored in the
system.
Troubleshooting
If you are experiencing problems getting the system to work properly, please use the following troubleshooting suggestions.
-
Ensure that all connectors 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.
– 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.
