Application Wiring
There are two different application methods with wiring examples shown below each.
APPLICATION 1 – BYOM (Bring Your Own Meeting)
This first application for BYOM includes two different methods of wiring, depending on the
capabilities of the connected laptop.
The first method can be used if the laptop supports USB Type-C where a single USB Type-C can
be used to project video from the connected laptop as well as receive microphone audio and
camera video from the HT-MERCURY. This method supports DP1.4, USB3.0, USB2.0 and PD (max
60W).

Hall Technologies November 2, 2022 Page 8 of 31
The second method is used if the laptop does not support USB Type-C. In this method both HDMI
and USB-A to USB-B cables are needed. The laptop uses the HDMI to project video through the
HT-MERCURY to the connected display and uses the USB-A to USB-B cable for microphone audio
and camera video from the HT-MERCURY.
APPLICATION 2 – ZOOM ROOM + BYOM
This second application for BYOM includes integrating the HT-MERCURY with a Zoom Room PC.
This is accomplished by adding a USB Capture device to convert the HDMI video out of the HT-
MERCURY into the Room PC along with a USB cable. In this application the laptop is used as a
source into the Room PC through the HT-MERCURY and the Room PC can view the source along
with the camera for Zoom calls.
USB-B

HT-Voyager Dongle

Note: After the HT-MERCURY is connected to a computer it can be detected by the system using
the following names:
Model: HT-MERCURY VIDEO BAR
Camera/Speaker/Microphone: HT-MERCURY VIDEO BAR
Bluetooth Pairing
The device can be controlled using the included Bluetooth remote controller once the two have
been paired with each other.
To pair with the Bluetooth remote controller:
1. Press and hold the pairing button located
on the right side (when looking at the front
of the HT-MERCURY). The front LED will
blink blue, which indicates that the device is
in Bluetooth pairing mode.
2. When the HT-MERCURY is in pairing mode,
press any button on the remote controller.
A pop-up on the display will include the
sentence “Remote Control Connected”
indicating that the Bluetooth pairing
between the remote controller and the HT-
MERCURY is successful.

Key Functions
SCREEN MIRRORING
With screen mirroring support, the HT-MERCURY allows you to share your mobile devices’
content wirelessly over AirPlay Mirroring, Miracast, Smart View and HT-Voyager. In this manual,
mobile devices available for screen mirroring are referred to as “screen mirroring sources”,
which include Apple devices (iPhone/iPad/Mac), Android phones, Windows PCs, and HT-
Voyager.
1. Screen mirroring using AirPlay
Using an iPhone 8 (iOS 15.2) for example:
5. Connect your iPhone to the soft AP of the device.
ð Soft AP SSID: this should be the same as the device name which can be obtained
from the OSD at the upper right corner of the display screen. By default, it is set as
HT-MERCURY.
ð Password: this password can be set through Web UI or Telnet API and can be obtained
from the OSD at the bottom right corner of the display screen. By default, it is set as
12345678.
6. Slide up from the bottom of the iPhone’s screen to
show the control center. Click Screen Mirroring
and choose the device name in the pop-up list.
7. HT-MERCURY now displays your iPhone’s screen.
8. To disconnect iPhone from the device: click
Stop Mirroring. The display stops displaying
your iPhone’s screen.

Hall Technologies November 2, 2022 Page 12 of 31
2. Screen mirroring using Smart View
For Android mobile (using Samsung Galaxy S9 for
example):
1. Enable the Wi-Fi or WLAN feature of the mobile.
2. Slide down from the top of the screen and click the
Smart View icon in the pop-up interface.
3. The Smart View window appears and starts to
search for Miracast receiver. Click the HT-MERCURY
device name in the search result and the device will
output the mobile screen.
3. Screen mirroring using Miracast
For Windows 10 PC:
1. Enable the WLAN feature of your PC.
2. Click the icon on bottom right of the screen to open Action Center.
3. Click Connect.

Hall Technologies November 2, 2022 Page 13 of 31
4. Click the HT-MERCURY device name in the
search results.
5. The HT-MERCURY device displays the PC’s
content once your PC is connected to the device
successfully.
6. To disconnect PC from the device: click
Disconnect.
Note:
" The icon and interface of the Miracast function may vary on different computers.
" Some Windows 10 computers may fail to perform screen mirroring with Miracast due to
compatibility issues.
Tip: Both the AirPlay mirroring and Miracast support access code. If you see the PIN entry
window appears on your devices, input the access code which can be obtained through
OSD. (See “OSD” section for more information.)
4. Screen mirroring using HT-Voyager
HT-Voyager allows you to share your laptop’s content on the display screen without installing
any additional software. Simply plug in the HT-Voyager into USB-C and click the button. For more
information, see the user guide of HT-Voyager.

Hall Technologies November 2, 2022 Page 14 of 31
Steps to share laptop’s screen on the display using HT-Voyager:
1. Pair the HT-Voyager with HT-MERCURY.
Connect the HT-Voyager to the PAIRING port of the HT-MERCURY for pairing. Once
pairing is completed, “Pairing successful” appears on the display screen. (This will take
around 20 seconds to complete.)
2. Connect the HT-Voyager to a laptop.
The HT-Voyager will start running when connected into a laptop and will automatically
connect to the switcher’s soft AP. Once the HT-Voyager connects to the HT-MERCURY
successfully, the HT-Voyager LED stops blinking and will be solid white.
3. To mirror the laptop, press the HT-Voyager’s projecting button. To display the laptop’s
screen in full screen, press and hold the button for at least 5 seconds.
Note: For more information about HT-Voyager, see the HT-Voyager user guide.
GUIDE SCREEN
The device uses a Guide Screen to convey the basic connection instructions for users. The Guide
Screen can be personalized to allow custom connection instructions on the device’s Web UI
page.
When all video sources are disconnected from the device, the following Guide Screen appears
on the display screen automatically:
Projecting Button

Hall Technologies November 2, 2022 Page 15 of 31
Note:
• This Guide Screen picture can be changed through the Web UI setting. Please refer to Guide
Screen section for more information.
• By default, if the Guide Screen is being displayed for 60 seconds with no wireless casting
connectivity, a countdown timer with the time period of 60 seconds will appear.
The Guide Screen is accessible in the following cases:
• Automatic switching: by disconnecting all video sources from the switcher, the
Guide Screen appears automatically.
• Manual switching:
è Through Web UI page. For more information, see State & Switch section.
è Send API command through telnet to the switcher to show the Guide Screen. For
more information, see the separate HT-MERCURY API documentation.
OSD
The switcher supports OSD (On Screen Display) to convey device basic information, including
the video source’s information, access code, device name, IP address, and Wi-Fi password. The
following is an example of OSD.
No Access Code
UAV-G709-000
WiFi Pwd:12345678
IP: 192.168.9.46
Guide
HT-MERCURY

Hall Technologies November 2, 2022 Page 16 of 31
Note:
• When the switcher outputs the Guide Screen, the OSD will be displayed continuously until the
countdown timer reaches zero.
• When the device outputs video input sources, the OSD will be displayed for 10 seconds and
then will disappear.
• By default, the access code is set as blank, and therefore the OSD doesn’t display the access
code. If you want to set access code, please see BYOD section for more information.
Web GUI
The Web UI designed for the HT-MERCURY allows for basic controls and device settings. This
Web UI can be accessed through a modern browser, e.g., Chrome, Safari, Firefox, IE10+, etc.
To get access the Web UI:
1. Connect the LAN port of the switcher to a local area network. Ensure there’s a DHCP server
in the network so that the device can obtain a valid IP address. (If there is no DHCP server
the video bar will revert to a 169.254.x.x address which you can find on the OSD. Use this
to change the video bar IP to a static IP address and set your own.)
2. Connect the PC to the same network as the video bar.
3. Input the video bar’s IP address in the browser and press Enter, the following window pops
up. (See OSD section to easily view the IP address)

Hall Technologies November 2, 2022 Page 17 of 31
4. Input the password (default password: admin) and click Login to enter the main page
