UHBX-R-XT
1.0 Introduction
The award winning UHBX-R-XT is an HDBaseT Receiver with integrated
HDBaseT transmitter for connection to downstream HDBaseT receiver(s) in a
daisy-chain fashion. It provides a local HDMI output, an RS-232 port for
controlling displays, and it also extends IR signals (IR signal detected at
source is broadcast to all receivers - IR cables sold separately).
The RS-232 port can be used to send commands (such as power on/off) to
compatible displays and projectors. This can be done either automatically
(autonomously by detecting video), or directed by an external Serial Control
Device using Hall Research's simple command set.
When RS-232 operation is under external control, each receiver in the daisy
chain can be individually addressed for sending specific commands at that
particular node. In order to communicate with a given receiver, each receiver
in the daisy-chain is assigned a unique address.
The UHBX-R-XT provides a Mini-USB port that is used to assign the box
address, configure operation mode, upload internal commands (required for
automatic on/off control), and more. A free Windows® GUI software is
available on the product's webpage for users who want to take advantage of
the product's control capabilities.
The distance between receivers (in a daisy chain), is 100 meters (328 ft)
maximum, however, if the video is limited to 1080p (24 bit color or
8bits/color), then users can utilize the “Long Reach” function of the receiver
that allows UTP cables of up to 150 meters (500 ft) between consecutive
receivers in the daisy-chain (Long-Reach mode does not support 4K or deep
color).

1.1 HDBaseT Daisy Chain
The video source needs to be connected to a compatible transmitter. Please
refer to section 3.1 below for a table listing of compatible senders.
Up to 8 UHBX-R-XT Receivers can be connected in a daisy chain. The last
unit in the daisy chain can be a lower cost receiver with no daisy-chain output
such as: UH-1BT-R, UH1-BTX-R, or UHBX-R. However, the serial port
function will not be compatible. Therefore, if you are using the addressable
serial port feature (see section 4.5), then the last unit in the daisy chain will
also have to be a UHBX-R-XT.

3.1 Installation
•The UHBX-R-XT is primarily 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 RS-232 for control, and IR
extension. The Table below lists recommended senders and their
characteristics.

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 100
meters (328 ft). The length of CAT6 cable plugged to the output depends on
the downstream receiver, but by default it too is good for at least 100 meters.
To achieve even longer distances, the receiver has a "Long Reach" 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). So if in your setup there is no choice and
you have to go beyond 100m, you have this option (limits your color depth to
8 bit, and resolution to 1080p).
If RS-232 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 4.5 below.
4.1 Distance Mode Switch
This switch affects the operation at the HDBaseT input. It
is recommended to leave it in AUTO. In LR mode, UTP
cable lengths of up to150 meters can be accommodated.
The slide switch is located under the HDMI OUTPUT
connector. To enable Long Reach mode place the switch
in L.R. position (use the tip of a pencil or a paper clip).

4.3 IR Connections
The extender can extend Infra-red Remote Control signals from the sender to
all the receiver. IR emitter cable is not provided and must be purchased
separately.
IR Emitter (Blaster) Cables
Currently two IR emitter cables are available: CIR-EMT and CIR-EMT2.
CIR-EMT, shown below, is recommended for most applications
IR Emitter Cable CIR-EMT
(Emitter has adhesive backing)
Pin out: Tip=Anode, Ring=Cathode, Sleeve=Not Connected
An alternative Emitter cable is CIR-KIT-EMT2. This cable is better suited for
situations where there is a need to isolate the IR signal to just one TV. It
comes with an adhesive rubber cover can be used to confine the IR beam to
just one target device directly over its IR sensor..
Alternate IR Emitter Cable CIR-EMT2
The CIR-EMT2 has a mono-type plug.
Pin out: Tip=Anode, Sleeve=Cathode
4.4 Power Connection
The extender requires 5vDC regulated operating voltage. A universal input
(110~240 VAC) external power supply is provided. The UHBX-R-XT features
power input supervisory circuit that protects the device if wrong power supply
is plugged in. But please do not substitute power supplies!

4.5 Using the Serial Port
Each UHBX-R-XT device provides an RS-232 port which is primarily there
for controlling a display (such as on and off functions). The pinout of the RS-
232 connector is as follows?

To best understand how this RS-232 port operates, refer to the image below.
RS-232 Functional Block Diagram
As shown in the block diagram above, each box has internal EEPROM for
programming and holding upto 6 individual commands. Also each box is
shipped with the same address (default address = 1), but the box address can
be changed.
If you will be using the internally stored commands or if you want to give each
box a unique address, a mini-USB port is provided (USB cable is also
included). Please download the Windows® GUI software from the product’s
webpage and install it on your PC. Instructions for the GUI is on the website.
There are 3 ways RS-232 Commands can be sent out on the UHBX-R-XT.
Using HDBaseT to construct and send a command
This method does not rely on the internally stored commands. The user can
address a particular box and connect to it. Then it can specify the baud rate for
the RS-232 port on the receiver, define the command, and send it out. When
only one box is being addressed, any RS-232 response received from the TV

Daisy Chainable HDBaseT™ Receiver

or projector connected, is also kept in a buffer and is readable through the
HDBaseT by the controller connected to the HDBaseT transmitter.
Using HDBaseT to send an internally stored command
To use this method, the user must have uploaded commands in the internal
memory of the UHBX-R-XT. Using the serial port on the HDBaseT sender,
the user can address a particular box and ask it to send out one of its 6 internal
commands.
Sending commands automatically by detecting video
The UHBX-R-XT can be set to send out the first two internal commands
automatically based on detecting video in the HDBaseT. Only the first two of
the internal commands are used, the first one is sent out when video is detected
(typically used to turn on a display), and after video is absent for a given
amount of time (the time is specifiable using the USB GUI), the UHBX-R-XT
will issue the off command.

11
UHBX-R-XT
5.0 Serial Commands
The UHBX-R-XT will be communicating with a host through its HDBaseT
input at a fixed baud rate of 9600 and no parity.
Command Response Function
XCn <cr>
XCn <cr>
Connect the host controller to a specific unit addressed by n.
n = 01 - 99 or * (for all)
If n is not specified, the unit reports an address of the unit
connected to the host controller
XT <cr>
XT <cr>
Transmit serial command from RS-232 port. This command should
be followed by a string of serial bytes to be sent out, and it is
terminated by two single bytes hex 17 and hex 0D
If you want to include Hex bytes in your string (mixed with ASCII),
define hex bytes with &h before the two digit number
Example:
XT <cr> (tells the receiver to get ready to receive command bytes)
HELLO WORLD&h0d (this is the string that will be sent out)
Hex 17 Hex 0D (send the command above. Of course you need to find out
how to send hex 17 and hex 0D through the HDBaseT sender. If a PC’s serial
port is used, you can press Ctrl+w for hex 17 and Enter for hex 0D)
XR <cr> x Bytes Read the response received at the RS-232 port. There is a 64 byte
receive FIFO on the RS232 port. Reading will also clear FIFO
XBn <cr> XBn <cr> Set baud rate for the local RS232 port.
n = 1, 2, 3, 4, 5, 6, 7, 8 correspond respectively to
baud = 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
XPn <cr> XPn <cr> Set parity for the RS232 port. n = 0,1,2 (None, Odd, and Even)
XSn <cr> XSn <cr> Send stored serial command out the RS232 port (n=1 - 6).
AMn <cr> AMn <cr> Set auto mode
n = 0 – 1 = Manual – Auto
ODn <cr>
ODn <cr>
Set auto off delay
n = 0 – 240 (in minutes)
FD <cr>
FD <cr>
Perform a factory default.
FW <cr>
FWx.x <cr>
Read firmware version.
NOTE: If n is not specified in any of the commands above, the command becomes a query command
instead of a set command. In response to a query command, the system reports the current status of that
command.

6.0 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 Switch
on the receiver 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.

8.0 Windows® Manager Software GUI
The UHBX-R-XT graphical user interface (GUI) is a Windows® software
used to configure advanced settings of the UHBX-R-XT. Use of the software
requires USB connection of the PC to the device. For convenience, a USB
cable is provided with the receiver.
After configuring the receiver, the user can save the desired configuration as a
file on their PC. Configuration files can also be uploaded to receiver.
The USB port can also be used to upgrade the firmware in the UHBX-R-XT.
There is a full manual for the GUI on the website. Below are basic features.
8.1 Status page
There are two main pages in the GUI. The status page is shown above. It gives
you visual indication of how the HDBaseT input and output are working
(mode, cable length, video detection), as well as how you have configured the
box (its Address, and serial port settings). This page also allows you to
manage the EDID.
EDID mode can be set to either emulate or pass-thru.
EDID
Emulate – In this mode, the internal default EDID is passed to the source.
Pass-thru (Default) – This is a default mode. When set to this mode, the
EDID passed to the source comes from a sink TV, LCD monitor, or
projector connected to the receiver.
EDID can be learned from a local HDMI monitor. The
saved EDID will automatically replace the emulated
EDID.

15
UHBX-R-XT
In a daisy chain, only the operation of the first receiver in the chain matters. It
is recommended that if you have any issues, make sure the TV is connected to
the HDMI output port of the receiver, Turn on the TV, then using the GUI
“LEARN” the EDID of the TV and then put the system in Emulate EDID
mode. From then on regardless of TVs being connected and powered, the
source will get proper EDID.
8.2 Configuration page
Use this page to define and upload upto 6 internal commands.
You can also enable the “Auto Power Mode” where the UHBX-R-XT sends
power on and off commands based on detecting video on the HDBaseT signal.
