Introduction
OVERVIEW
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.

Setup
INSTALLATION
• Connect the HDMI Input on the UH18-S (Sender) to your
HDMI Source using a
High quality HDMI cable such as Hall
Technologies 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.
• 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 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).
• 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.
• 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.

Functions
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.
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.
- USB Devices such as Webcams that require isochronous
transfers may not work in Long Reach Mode.
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.

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
fullduplex communication.
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
