Key Functions
Screen Mirroring
If you’re working on a PC and want its apps and content to be shown on another screen, you’ll want to consider mirroring your PC’s screen to that screen. With screen mirroring support, the device allows you to share your mobile devices’ content wirelessly on any HDMI displays over Airplay Mirroring, Miracast and Dongle.
In this manual, mobile devices available for screen mirroring are referred to as “screen mirroring source”, which include Apple devices (iPhone/iPad/Mac), Android phones, Windows PCs and Dongles.
(1) Screen Mirroring over Airplay (for Apple Devices)

1. Connect your iPhone/iPad/Mac to the soft AP of the device.

Soft AP SSID: As same as the switcher’s device name and can be obtained from OSD at the upper right of the display screen. By default, it is set as SW- 640L-TX-W. Password: Set through Web UI or Telnet API and can be obtained from OSD at the bottom right of the display screen. By default, it is set as 12345678.

2. Open Control Center on your Apple device, tap up menu.

to select appropriate mirroring device (default device name is SW-640L-TX-W) from the pop-

3. To disconnect Apple device from the switcher: click Stop Mirroring, the display stops displaying your device’s screen.

(2) Screen Mirroring over Miracast (for Android Phones & Windows PCs)
For Android mobiles (take Samsung Galaxy series for example): 1. Enable the Wi-Fi or WLAN feature of your mobile device. 2. On your mobile device, swipe down from the top and tap or to select appropriate mirroring device from the pop-up CONNECT menu. 3. To disconnect mobile phone from the switcher: click “DISCONNECT” on your mobile phone’s screen.
Note: · The icon, instruction and entrance of the Miracast function may vary on different Android mobiles, please refer to your mobile’s manual to get
accurate instruction. · If you fail to use Miracast function, please disable the mobile’s Wi-Fi and enable it later, or restart the mobile if necessary.
For Windows PC (Window 10 or higher): 1. Enable the Wi-Fi or WLAN feature of your PC. 2. On your PC, press the combination keys ” + K” to select appropriate mirroring device from the pop-up menu. 3. To disconnect PC from the device: click Disconnect, the display stops displaying PC’s screen.
Note: The icon and interface of the Miracast function may vary on different computers. Some Windows 10/11 computers may fail to perform screen mirroring over 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.)

(3) Screen Mirroring over Dongle
A Dongle (APO DG2) enables users to share laptop’s content on a display wirelessly without even installing an application.
To pair a Dongle:
1. Pair a Dongle with the device. Connect a Dongle to the DONGLE PAIRING port of the device for pairing. Once pairing is completed, “Pairing successful” appears on the display screen.
2. Connect the Dongle to a laptop. Connect the Dongle to the laptop, it will start running and connecting to the device’s soft AP. Once the Dongle connects to the device successfully, the Dongle LED stops blinking and starts lighting constantly.
3. Now press the Dongle’s projecting button, you can share your laptop’s screen on the display immediately. Press and hold the button for at least 5 seconds, you will have your laptop’s screen displayed in full screen.

Note: For more information about the Dongle, see its user guide.

Multiview Display

When only one HDMI display is attached to either HDMI OUT1 or HDMI OUT2, the device supports up to four video sources to be played on the display screen as the following:

1

2

1

2

1

1

2

3

4

3

1. As the video sources to be displayed increase or decrease, the device automatically changes to a new screen layout so that all video sources can be displayed appropriately on the entire screen.
2. As the video sources increase till there’s no available screen layout to accommodate for all these sources, if a new video source inputs, the source that displays on the screen for the longest will be displaced by the latest input source.
If you use the SELECT button on front panel to select a video source to be played, the device will exit Multiview Display mode and display the source in full screen.

Automatic Signal Switching
The device supports automatic signal switching function, allowing you to easily and quickly output desired sources. It follows Last-In-First-Out rule:
1. When only one video source is connected to the device, HDMI OUT 1 and/or HDMI OUT 2 will automatically output this video source to the display screen(s).
2. When a video source is to be input in the case that four video sources are being played in quadruple view on one display screen, this latest input source will displace the source that is present the longest. More information, see the switching mechanism in Multiview Display section.
3. When no active video source is connected to the device, the output display shows the Guide Screen image finally.
The device also provides three methods to select specific video source manually:
1. Using the front panel buttons to output corresponding hardware video source. 2. Using web UI. 3. Using API commands. For more information, please see the separate API documentation.

Display Mechanism of HDMI OUT1 & HDMI OUT2
By default, when HDMI OUT1 and HDMI OUT2 are connected to two display screens respectively, the two output ports work as follows:
1. Each of the HDMI outputs displays the video in full screen view. 2. If the device detects no active video source, both HDMI outputs display Guide Screen. 3. If the device detects only one active video source, both HDMI outputs display this video source. 4. If the device detects the quantity of the input video source increases
Dual Desktop Mode for HDMI Inputs
Dual Desktop mode is available and runs as follows:
1. When HDMI IN1 and HDMI IN2 are being output, Dual Desktop mode is activated: the source at HDMI IN1 is delivered to HDMI OUT1, and source at HDMI IN 2 is assigned to HDMI OUT2.
2. If a video source is to be input in the case that Dual Desktop mode is activated, the source that is assigned to HDMI OUT2 will be displaced by the recently input source, and the device will exit Dual Desktop mode.
3. When Dual Desktop mode is activated, if one HDMI source at either HDMI IN1 or HDMI IN2 is removed from the device, the device exits Dual Desktop mode and the two HDMI outputs display another HDMI source.

Guide Screen
The device outputs Guide Screen image when no video source is selected or being output. The Guide Screen can be personalized on the device’s Web UI page to convey customized connection instructions.

The Guide Screen is accessible in the following cases: · Automatic switching:
Disconnect all video sources from the device, the Guide Screen appears automatically. · Manual switching:
Log on to the web UI page to select Guide Screen for the HDMI outputs. For more information see the Input Switching section. Send API command through telnet to the device to show the Guide Screen. For more information see the separate API documentation.
Tip: This Guide Screen image can be changed though Web UI, for more information refer to Splash Screen section. By default, if the device is outputting Guide Screen picture for 60 seconds, a 60-second OSD countdown will appear on the Guide Screen. When the countdown reaches zero, the device will enter standby status.
OSD
The device comes with OSD (On Screen Display) support, enables users to view basic information of the device, including video source channel, access code, device name and IP address, etc. Here are two different OSD examples:
Example 1: Full Screen Mode

Note:
· When the device outputs Guide Screen image, the OSD is shown all the time. · When the switcher outputs specific video sources, the OSD will display on the display device for 10 seconds and then disappear. · By default, the access code is set as blank, therefore the OSD doesn’t display the access code.
