1.0 Introduction
The UH18 extends HDMI Video and USB 2.0 on a single CAT6 cable to
100 meters or more. The extender kit consists of a Sender (UH18-S)
and Receiver (UH18-R). Power, USB, RS-232 and IR (remote) extend on
the same cable. The power supply connects to either side of the
extender.
The UH18 provides 18 Gbps video bandwidth and supports HDMI
resolutions up to and including 4K @ 60 Hz 4:4:4 (UHD). The Sender
has a built in video splitter and features a convenient local HDMI video
output connector.
USB 2.0 extends from a USB host connected at the Sender. Both the
Sender and the Receiver have USB hubs with two USB device ports for
connecting USB devices such as a keyboard, mouse, touch screen,
printer, flash drive, web cam or other USB 1.1/2.0 device.
The extender kit also provides a user selectable “LONG REACH” mode
switch. In this mode, the extender kit can support distances to 150
meters (500 feet) with a maximum resolution of 1920x1080 (1080p).
HDMI audio extracts in both stereo analog (L/R) and digital (SPDIF)
RCA formats.

3.0 Setup
3.1 Installation
 Connect the HDMI Input on the UH18-S
(Sender) to your HDMI Source using a
High quality HDMI cable such as Hall
Research CHD-SF* SnugFit™ High Speed
Latching HDMI cable (HDMI cables are
not included).
 Use the included USB 2.0 Type A-male to B-male cable or other quality
USB cables to connect the USB 2.0 port on the Sender to your PC or USB
Host.
 If you need to connect any local USB devices such as a keyboard, mouse
or KVM Switch; the UH18-S provides two USB ports for this purpose. This
is useful particularly if your PC or laptop has a limited number of USB
ports.
 If required, connect the HDMI loop output of the Sender to a Display.
 Use a single CAT6 UTP or STP cable to connect the HDBaseT output
(HDBT OUT) on the Sender to the HDBaseT input (HDBT IN) on the
Receiver.
(Shielded CAT6 cable is recommended for maximum distance or for cases where the CAT6
cable is pulled with other data communication, or electrical cables).
NOTE If you are extending more than 100 meters and your
resolution is 1080P maximum, enable Long Reach Mode
on both the Sender and the Receiver using the switch on
the front panel.
NOTE Do not block the vents on Sender and Receiver and allow
enough space around the units for air circulation to prevent
units from overheating.

 Use the supplied 24 VDC Power Supply to power the Extender. Only one
power supply needed and may connect to either the Sender or Receiver
depending on your requirements. By default, the power supply is only
included with the Sender (UH18-S).
 Connect USB 2.0 devices that you want to extend to the USB Hub on the
Receiver
 The extender set includes only one IR Detector cable, and one IR Emitter
cable. It can extend IR Remote control signals in either direction (from
Sender to the Receiver or vice versa. If you are going to extend IR Remote
control signals along with the HDMI video, you should first decide in
which direction you want to send the signal. For example, if there is a
Cable TV box at the Sender that you want to control from the remote end
where the TV is located, then you want to plug the IR Detector cable to
the IR IN of the Receiver and the IR emitter cable to the IR OUT of the
Sender. That way you can use the Cable TV Remote from the remote side
to control it.
 Connect any Serial Devices/Controllers to the RS-232 port as required.
The RS-232 extension is pass-through and supports all baud rates up to
115 Kbps.
 Connect any speakers or audio equipment to the de-embedded HDMI
audio outputs on the Receiver.

5.0 Functions
5.1 EDID Management
The UH18-S Sender can pass either the Local or Remote EDID to the video
source.
To pass the remote EDID of the display connected to the HDMI Output of the
Receiver, turn the Local EDID DIP switch on the front panel OFF. This is the
default mode.
To pass the local EDID of the display connected to the Local HDMI Output of the
Sender, turn the Local EDID DIP Switch on the front panel ON.
The Sender will remember the last EDID connected until a different display is
connected.
Disconnecting the remote display will not affect the video on the HDMI Output
on the Sender.
5.2 Long Reach Mode
Use Long Reach Mode to extend video and audio beyond the 100 m range.
You can extend 1080P @ 60 Hz video maximum up to 150 m.
If you do not intend to extend 4K (UHD) video, you can set the Long Reach DIP
switch to ON.
This reduces the bandwidth utilized in the UTP cable and improves signal
immunity to outside interference.
In Long Reach Mode, an internal custom EDID informs the source to output
1080p @ 60 Hz video.
NOTE USB Devices such as Webcams that require isochronous
transfers may not work in Long Reach Mode.

5.3 IR Extension
The bi-directional IR extension is pass-through.
Connect the IR Detector and Emitter cables to the Sender and Receiver to
extend IR in both directions.
Only one IR Detector cable and one IR emitter cable are provided in the
extender kit.
To extend IR simultaneously in both directions, you need to purchase extra IR
cables. Contact Hall Research Sales for more information.

5.4 RS-232 Extension
The RS-232 Extension in UH18 is pass-through and
works up to 115K baud.
The baud rate settings of the serial device connected at
the Sender must match with the serial device
connected at the Receiver end for successful full-
duplex communication.
6.0 Troubleshooting
USB 2.0 Camera is Lagging
Check if Long Reach mode is ON. If so, turn it off.
Isochronous transfers may not work if Long Reach mode is ON.
No video on the Receiver
Check the PWR led on both Sender and Receiver
Check if HDMI LED on the Sender is Turned ON
Check if the HDMI LED on the Receiver is Turned ON
Check the Cable Length
6.1 Contacting Hall Research
