1.0 Introduction
The UHBX-3S and UHBX-6S are HDMI splitters with one local HDMI output and
3 or 6 HDBaseT outputs for transmission to compatible receivers up to 150
meters / 500 ft in Long Reach mode, or 100 meters / 328 ft in Standard mode
using UTP cables (max distance is a function of receiver type and cable quality).
The Splitter supports 4K (UHD) video (4K/30 4:4:4, or 4K/60 4:2:0), HDCP, 3D,
Deep Color, and CEC. The splitter also provides true EDID management with
"Pass-thru", "Learn", and "Emulate" capabilities.
Advanced users can download, edit, and upload EDID data to and from the
device using the provided USB port. The unit offers an RS-232 port that can
individually address and control remote displays with RS-232 interface. The
HDBaseT Splitter provides convenient front panel LED status indicators for all
HDBaseT parameters so the user can quickly view the system status.
The UHBX-3S/6S supports PoH (Power over HDBaseT) to the remote receivers
using a 48 vDC power supply (part number 511-PS4815).
Typical Connection Diagram
The HDBaseT compliant PoH performs the necessary low voltage handshake
(per IEEE802.3af) prior to injecting full supply voltage on the UTP line for
maximum reliability, safety and compliance.

3.0 Setup
Installation
As shown in the diagram below, the UHBX-3S/6S can extend a single video
source to multiple remote displays. There is also an additional HDMI output
for connection to a local display or for daisy chaining to another Splitter. A
maximum of (7) Splitters can be daisy-chained together.
RS-232 and Power (PoH) signals are also extended on the same Cat 6 cable to
compatible Receivers. The RS-232 IN port is used to send/receive commands
or data to/from remote displays connected at the output. Special RS-232
commands must be used to communicate with any individual output (Refer to
Section 5 for more details).

To use the RS-232 port, connect the RS-232 input (Female) connector to your
controller or PC using a straight-through male-to-female DB9 cable. The pin-
outs are shown below:

To daisy chain splitters, use a M/M HDMI connector to connect HDMI-OUT from
the first unit to the HDMI In of the down-stream box.
If RS-232 is used, connect the RS-232 OUT connector to RS-232 IN of the next
box. Remember that when more than one unit is daisy-chained, you must assign
the addresses for each the outputs so they can individually address a particular
RJ45 and send out a command via RS-232 to the remote receiver.

NOTE By default, the output port numbers are assigned address 1
through 3. (Or 1 through 6). To assign a different range, the
user must connect the Splitter to a PC using the supplied USB
cable and use the appropriate "UHBX-3S or 6S Manager
Software" from the Hall Research website.

4.0 Operation
Make the connections as shown in the figure above and power up the UHBX-3/6S.
If the UHBX-R-PD is used as the receiver, the PoH LED will illuminate after about
3 seconds to indicate that the receiver is also receiving power.
When the Link LEDs on front panel and receiver are lit (or blinking), the system is
ready to extend video.
If you have video connected, it should be visible on the remote displays.
For maximum capability, we recommended that the EDID switch be left in pass-thru
(PASS) position, but if you are not getting an image, try changing to the emulated
(EMUL) position.
Front Panel LEDs
Link
Solid on means the splitter and receiver are communicating.
Blinking means they are in communicating, but in Low-Power mode
Video
Solid on means Video is being sent to the display
Long Reach
Solid on means the link is operating in Long Reach mode
PoH
Solid on means PoH is active and power is being sent to receiver
As shipped from factory, the HDBaseT ports of the splitter are in AUTO mode, in
this mode if a UHBX-R-PSE is used, the link mode should be set to standard
(100m) or Long Reach (150m) using the mode switch on the receiver.
If the Link, Video, and Long Reach LED’s are blinking together, this indicates
there has been a failure on the corresponding HDBaseT transmitter port.
Contact Hall Research Support department for assistance.

EDID Management
A main feature of the Splitters is EDID management.
Two modes of operation are supported, Pass-Through or Emulate. The mode is
selectable from the front panel of the splitter.
In Pass-through mode, the EDID of the TV connected to the selected output
passes to the video source.
In Emulate mode, the splitter allows the user to send an EDID table that is
stored in the splitter itself to the video source.
The internal EDID table is modifiable in two ways.
1. The EDID can be "learned" from the display connected to the local
HDMI output (by holding the SEL button for 5 seconds).
2. The user can upload any valid EDID table from a PC using the GUI
through the USB port. "Learning" from a remote display is also possible.
To switch between EMULATE and PASS-THRU modes, press the front panel SEL
button.
PASS
Solid On means the current EDID data is from connected displays
EMUL
Solid On means the EDID data is being EMULATED.
Blinking means the selected mode is Pass-Thru (PASS LED will be
solidly lit), but the splitter could not find any sinks connected so the
EDID was defaulted to being Emulated.
5.0 Serial (RS-232) Commands
The Splitter has special commands that can selectively send data to the
HDBaseT outputs.
When daisy chaining multiple splitters, assign each with a unique number to
each splitter output port using the Windows™ GUI Software. Refer to the
software guide for more details.

Serial Commands
Command: XC,n<cr> stands for Serial Connect
Connect serial interface to output (n). If n is not specified, then it reports which
output the controller is connected. “n” is in the range of 1 to 99. Default is 1.
Response: XC,n <cr>
This indicates the command completed successfully
Command: XT<cr> stands for Serial Transmit
The string of characters (bytes) to send follows this command. The unit will
wait up to 5 seconds to start receiving the characters to send. Enter any byte
from 0x00 to 0xFF. The maximum number of bytes to send cannot exceed 64.
To indicate you are finished sending the data, you must send a 0x17 byte
followed by 0x0D. This sequence initiates the transmission.
Response: OK<cr>
We recommend waiting for the "OK" response prior to issuing further
commands to the splitter to avoid the risk of corrupting the internal buffers.
Command: XR<cr> stands for Serial Read
Reads the receive buffer. The unit can store up to 64 bytes from the device
being controlled.
Response: x bytes as received or possibly none
Command: XB,n<cr> stands for Serial Baud
If n is not specified, it reports the current baud rate (n = 1-8 per table below)
Response: XBn <cr>
Command: XP,n <cr> stands for Serial Parity
If n is not specified, it reports the current parity. n: (0 = None, 1=Odd, 2=Even)
Response: XP,n <cr>

Baud
Rate 1200 2400 4800 9600 19200 38400 57600 115200
NOTE “XB,n” and “XP,n” are global commands and will affect the
setting for all HDBaseT outputs. If all remote devices use the
same baud rate, you only need to issue the XB,n command
once. Otherwise you need to use the XB,n commands prior to
sending data to individual outputs.

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.
•Try resetting the system by cycling power on the Splitter.
•Check the state of the LEDs on the front of both the sender and the
receiver. If the Link, Video, and Long Reach LED's are blinking together,
there has been a failure on the corresponding transmitter port.
•Change the EDID mode using the front panel SEL button.
•Make sure the CAT6 cables are not in proximity to any power cables or
ballasts. Even if the length of the cable is less than 100 meters, if the
screen is periodically blanking or shows glitches, place the HDBaseT
link in Long Reach mode. In Long Reach mode, the signal is much
stronger, can go farther and offers extra immunity to interference and
electrostatic discharge (ESD). When using an UHBX-R-PD as receiver,
put the link into Long Reach mode using the small slide switch located
under the HDMI output connector.
•Update the firmware in the splitter if available (contact Hall Research
Support)
•Make sure, only high quality UTP or STP cables are used.
•If you still are unable to get the system working, contact Hall Research
support with a detailed description of the issue and the 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.
NOTE Backup any existing device configuration prior to resetting
factory defaults. All user programming will be erased.
