The Model UHBX-SW3-WP is a video extender with 3 video inputs in a 2-

gang wall plate form factor. The video inputs are:

•Input 1 – HDMI or MHL (Mobile High-Definition Link )

•Input 2 – HDMI

•Input 3 – VGA or YPbPr with separate audio

The wall plate can manually or automatically switch between the various

video inputs, and send user defined RS232 commands to control the

On/Off state of the display. The wall plate also features an IR sensor and

can extend IR control signals to the Receiver. For a few IR protocols, if the

format, data, and address bytes of the IR signal are known, the wall plate

may also be capable of generating the IR signals.

Using just a single twisted pair (Cat6) cable, the wall plate connects to a

compatible receiver, such as the model UHBX-R-PSE.

The single Cat6 cable carries all AV and control signals (RS232 or IR) from

the wall plate to the receiver. The same Cat6 cable also delivers power to

the wall plate using Power-over-HDBaseT (PoH) standard as defined by

HDBaseT®Alliance. There is no power input connection on the wall plate,

so a PoH compliant receiver that acts as PSE (Power Sourcing Equipment)

is required.

First ensure that the Receiver power is off by unplugging the power supply

from the Receiver. Then connect a Cat6 from the RJ45 HDBaseT Output of

the wall plate to the Receiver. There are two RJ45's on the wall plate, so

make sure to use the one labeled as HDBaseT Output.

The Wall plate can be directly plugged in to displays or projectors with

HDBaseT®inputs. In this configuration the wall plate still sends RS232

control commands to the display (check your display’s specifications for

details). To power up the wall plate, a power inserter would be required as

shown below (Hall Research PoH inserter p/n 511-POH-17W).

Hall Research 714.641.6607 Page 4

The wall plate can be used to control the display on/off function (Power

Command). The wall plate can store and send RS232 control commands to

displays or projectors with RS232 control capability. The wall plate can

extend IR signals, by pointing IR remote to the wall plate and connecting

an IR emitter to the Receiver, however the wall plate also has limited

capability to generate user defined IR commands and some popular IR

protocols are supported. Since there are thousands of IR commands and

dozens of protocols, it may be difficult for the user to obtain all the

information necessary for IR control. Using programmed IR commands is

further complicated because to keep the power state of the wall plate

synchronized with the TV, unique IR commands for ON and OFF are

needed. Many TVs only have one IR command that toggles the state

between on and off, making programmed IR control unsuitable.

To configure the wall plate and enter RS232 power commands for your

display, the wall plate provides a mini-USB connector (on the bottom side)

and is shipped with a USB cable that can be connected to any Windows®

PC. A free Windows®GUI software is available on the product's webpage.

It is the user’s responsibly to determine, for their specific display, the

control method and to obtain the commands from the display

manufacturer.

As mentioned earlier for best results use a display or a projector with an

RS232 control port if you desire the wall plate to control its power.

Supports MHL with charging feature

As shipped from the factory the wall plate is in full manual mode. This

means that you have to manually turn on the wall plate and also manually

select the input source you want displayed.

If you have defined a display Power On command, then the wall plate will

issue that command at the same time it turns on. So all you have to do is

press the power button on the wall plate once.

1. Press the power button

The red LED above the power button will turn on and also one of the

3 green LEDs next to the inputs will turn on to indicate which source

is selected

To change input, press the SOURCE button. For each press the green

LED next to each input connector will successively illuminate.

To turn off the wall plate, press the power button. If you have defined a

display Power Off command, the wall plate will issue the command as it

turns off.

Hall Research 714.641.6607 Page 6

The wall plate has the ability to detect video connections on its inputs and

automatically switch to the connected input.

Change the mode to "Auto Source" either from the button on the wall plate

or using PC software thru the USB port. From the GUI software you can

also lock the Auto Source mode (so it will stay in that mode permanently).

To enable Auto Source mode first make sure the wall plate is on. Press and

hold the Source button for 3 seconds. The red LED above the Source button

will turn on (and blink slowly). This indicates that the wall plate will

automatically select inputs. In this mode, pressing the Source button will

not change inputs.

If the wall plate is turned off and back on, it will recall this mode.

If the Auto Source mode is not locked by the GUI, you can exit this mode

from the wall plate by holding the Source button for 3 seconds. The red

LED above the Source button will turn off.

Notice The user can prioritize inputs, in case more than one is active.

As shipped from factory, HDMI 1 has the highest priority, then HDMI 2,

and last the VGA input. So if the only active input is VGA and you plug in

a source to HDMI 2 or HDMI 1, the wall plate will select the HDMI input.

Priorities can be changed through the USB port using the free manager

software GUI (Graphical User Interface).

If you do not want inputs to usurp each other, you can assign the same

priority level to them in the GUI. That way, once an input is detected, the

wall plate will stay on it until the video is disconnected.

Component Video cannot be auto-detected. So if you are connecting

YPbPr Component to the VGA input, you must select it manually.

The wall plate can send power on/off commands to the display

automatically based on sensing video on its selected input.

In Auto Power Command mode when the wall plate detects video on the

selected input it will issue an ON command to the screen, and if there is no

video being detected, an OFF command will be issued after a user specified

delay (default delay = 5 minutes).

You can enter the Auto Power Command mode either from the wall plate

or by using the GUI (via USB interface). The GUI also allows you to also lock

the Auto Power Command mode (so it will stay in that mode permanently).

To enable Auto Power Command mode from the panel, first make sure the

wall plate is on. Press and hold the power button for 3 seconds. The red

LED above the power button will start blinking slowly. This indicates that

the wall plate will automatically send on and off commands to the display.

In this mode, pressing the power button will not do anything.

If not locked from the GUI, you can exit Auto Power Command mode by

pressing and holding the Power button for 3 seconds. The red LED above

the Source button will stop blinking. Now you can manually turn the panel

on and off (and at the same time issue commands to the display).

The wall plate features an IR detector that can be used to extend IR to the

remote receiver. An IR blaster cable will be required to plug to the receiver

(Hall Research model CIR-EMT or CIR-EMT2). In this way the user can

point the IR remote to the wall plate and control the display. It is important

that the IR light signal blasted from the IR emitter at the receiver is not

incident on the wall plate's IR detector, since that will create a positive

feedback condition and can interfere with proper function.

Hall Research 714.641.6607 Page 8

The UHBX-SW3-WP scales the VGA input to 720p or 1080p in order to

eliminate compatibility issues with the myriad of VGA resolutions that may

not be supported on most TV’s HDMI input. Scaling the VGA to 1080p

(default) which is a standard HDTV resolution assures that there will be a

perfect display regardless of the VGA signal source timing. The scaler is

designed to work out of the box with no adjustments. However for

advanced users, the GUI provides many advanced features such as

underscan (zoom out), aspect ratio, brightness, etc.

Since VGA is an analog signal the scaler detects the edges of the video and

fits it to the display. Similar to VGA monitors, the wall plate has an “Auto

Adjust” feature. In the unlikely event that the VGA image on the display is

grossly misaligned, press both power and source buttons on the panel

simultaneously. This will start the “Auto Adjust” procedure after resetting

the wall plate (takes about 15 seconds to complete).

Using HD15 to 3 RCA cable, the VGA input can

accommodate component video (YPbPr). But you have to

configure the wall plate to expect YPbPr using the configuration GUI. In

this mode, the Auto Source selection mode is not available.

The user can configure the unit to pass-through the 3.5mm audio input

(associated with the VGA) on its HDMI output signal without having to

connect a live VGA signal. In this way audio from MP3 audio players can

also be extended to the TV (screen will be dark). To enable pass-thru of

3.5mm audio without VGA signal, refer to the configuration Software

documentation.

HDBaseT Output.

The wall plate requires PoH (power over HDBaseT), so the

receiver has to be a PSE (power sourcing equipment) type, or a

power inserter is needed.

Mini-USB port for connection to a PC. A free GUI is available that

can be used to configure the wall plate. A USB to mini-USB cable is

provided

For connection to SW3-UI and SW3-UI-VOL optional auxiliary

control panel (sold separately)

The wall plate is ready to use out of the box and in many cases no special

configuration is needed.

If the user desires to control the On/Off function of the display or to tweak

some of the parameters (such as prioritizing the input selection in Auto

input mode), a onetime set up is needed.
