1.0 Introduction
The UHBX-R-WP is a compact HDBaseT receiver in a wall plate. Perfectly
suited for installations with shallow space between the wall and display, the
receiver extends HDMI, IR and RS232 to 150m (500ft). The Receiver is
powered via HDBaseT from the sender and no additional power supply is
needed. RS232 and bi-directional IR ports are perfect for control. The unit is
compatible with any compliant HDBaseT Transmitter (sender) with PoH
sourcing function such as Hall Research UHBX-S-PSE (see section 3.1 for a
list of compatible senders).
The UHBX-R-WP has a Mini-USB port (located inside enclosure) which is
used to access the device's advanced settings or update its firmware using
Windows® GUI software (available on the product's webpage).
The UHBX-R-WP graphical user interface (GUI) is a Windows® software
used to view the HDBaseT® input status, to configure advanced settings such
as power management, or to update firmware version of the device. Use of the
software requires USB connection the device and a Windows® PC. For
convenience, a USB cable is provided with the receiver.

The maximum distance between the sender and receiver in Long Reach mode
is 150 meters (500 ft). Long Reach mode does not support 4K video or higher
than 8 bit color depth. In Standard mode, it is 100 meters (330 ft) for 1080p
video or 70 meters (230 ft) for 4K video.
The Distance Mode Switch is located on the circuit board and accessible by
removing the wall-plate cover (see section 4.1)

3.1 Installation
•The UHBX-R-WP is an HDBaseT™ receiver, meaning that a
compatible transmitter (sender) must already exist in the system. Hall
Research provides various compatible transmitters, from economical
video only, to video, plus RS232 for control, and IR extension. The
Table below lists recommended senders and their characteristics.

Connect a good quality HDMI cable to the HDMI output of the unit to a
display device. The HDMI output connector on the box has a locking nut
above it. Hall Research offers compatible locking HDMI cables.

If IR Extension is required, connect compatible I.R. Emitter and detector
cables to the respective 3.5 mm connectors. Recommended IR emitter: p/n
CIR-EMT and IR detector cable: p/n CIR-DET-P2.
4.0 Configuration
As shipped, no user configuration is needed for extending HDMI video. By
default the length of CAT6 cable plugged to the input can be as long as 150
meters (500 ft).
To achieve 150m, the receiver has to be in "Long Reach" distance mode
setting. If the HDBaseT “Source Device” connected to the input of the
receiver also supports "Long Reach" operation, 1080p video (with 8-bit color)
can be extended to 150m (500 ft).
If RS232 control output is going to be used (for example to control on/off
function of compatible TV or projector connected to the HDMI output, please
refer to section 4.3 below.
4.1 Distance Mode Switch
This switch affects the operation at the HDBaseT input. It is recommended to
leave it in Auto (standard) position. In LR mode, UTP cable lengths of up
to150 m can be accommodated but deep color and 4K video are not supported.
Figure 4 – Location of Distance Mode Switch on the Circuit board
The slide switch is located on the right side of the IR OUTPUT connector on
the PC board. To change the setting, open the metal plate and slide the switch
to desired position using the tip of a pencil or a small screw driver.

4.2 LED Indicators
The front panel of the wall plate contains LEDs that show the state of
operation.
Figure 5 – LED Indicators
POWER Used as power indicator. Comes on after the wall plate successfully
negotiates PoH and gets power from the PSE sender (or power inserter).
If it is lit dimly (or blinking) , it means that PoH function is working but
there is some sort of other malfunction on the board such as over
temperature (it will go to low power mode and automatically recover
when temperature is back to acceptable range), or HDBaseT logic circuit
is experiencing problems.
VIDEO Displays Video Status. Off = No Video being received, Blinking = Video
without HDCP is being received, Solid ON = Video with HDCP is received
LINK Solid on means the HDBaseT input is connected to and communicating
with the up-stream sender. Blinking means Link has been established but
the unit is in low power mode. Off means the HDBaseT link to the sender
is not working (check cable length, cable quality, connection integrity).
4.3 More on RS-232 Serial Connection and Operation
If required, plug DB9 null modem RS232 cable from the Receiver to the
device being controlled (such as a projector or switcher). Pin out of the Male

The UHBX-R-WP supports bidirectional RS232 and communicates with a
host through its HDBaseT input at a baud rate ranging from 110 thru 115200.
4.3.1 Power Management and RS-232 Operation
By default “Power Management” is turned on. This means that if there is no
video being extended, after some time, the system will place it’s HDBaseT
link in low power mode (and consume only about 10% of normal power). The
system will wait for HDMI source signal to become active (and for HPD from
connected TV to be asserted) and will wake up on its own.
A characteristic of HDBaseT chipset is that in low power mode it only
supports RS-232 up to 9600 baud. So if power mgmt is active (default) and

HDBaseTTM Wall Plate Receiver

you want to send RS-232 commands having higher baud-rate than 9600, the
data may not go through when there is no video being extended.
The UHBX-R-WP does have a wakeup on RS-232 function so even if it is in
low power mode, it will wake up and go into full power mode if it detects RS-
232 data coming through. Therefore users may have to send the command
twice if there is no video. The first command wakes up the system and after a
short delay, the repeated command will go through error free.
If you are using RS-232 communication when there is no video and do not
want to send commands twice as described above, then you can turn the power
management feature off. This is done by connecting the mini-USB port on the
wall-plate (under the front cover) to a Windows® PC and using GUI disable
the Power Management feature. When power mgmt is off, the HDBaseT link
will stay fully awake even if there is no video. This will increase power
consumption.

5.0 Troubleshooting
If you are experiencing problems getting the extender to work properly, please
use the following troubleshooting suggestions.
Make sure that all of the connections on both the sender and the receiver
are solid. Loose connections are the number one cause of issues.
Try resetting the system by unplugging the power supply connected to
the sender side, waiting 5 seconds and plugging it back.
Check the state of the LED’s on the front of both the sender and the
receiver. Refer to the table in section 4.2 to interpret the status being
indicated. Alternatively, hookup the USB port to a PC and run the
Windows® GUI and check the status indicators in the GUI.
If the cable length is longer than 100 meters (330 ft) set the Mode on the
sender to L.R. (Long Reach) position (see section 4.1). Note that in L.R.
mode the unit does not support deep-color video.

Make sure the display is compatible with the video source by connecting
them directly.
Make sure that the UTP or STP cable meets the requirements. Never use
low-skew cable for digital video extension. We recommend using CAT6
or CAT6a. In noisy environments use Shielded Cat6 (23 gauge).
The extender requires that the source DDC signals of its HDMI output
operate at100 KHz or less and support clock-stretching. The vast
majority of sources meet these requirements. But if you determine that a
particular source does not (by substituting a video pattern generator, or a
different source), an HDMI transceiver may be needed. Hall Research
offers the model HD-AUD that has a compatible output, can handle
virtually any HDMI input, and can resolve source incompatibility issues.
If you still are not able to get the system working properly, contact Hall
Research support (preferably via email or the form on support page of
www.hallresearch .com) with a detailed description of the issue and the
troubleshooting steps you have taken.
Do not open or try to repair the unit yourself as this will void your warranty.
To return the extender for repair, you must contact HR Support at 714-641-
6607 or via email or web. To ship the unit back for repair, make sure to obtain
a Return Material Authorization (RMA) number.
