5 Product Usage

5.1 Operation Steps

1. Connect the display screen power supply to power on the screen.
2. Connect a playable input source to the HD-VP1640A.
3. Connect the computer to the USB serial port and debug the screen parameters (refer to the HDSet user manual for debugging screen parameters).

5.2 Input Source Switching

The HD-VP1640A supports simultaneous access to 6 signal sources and allows switching to the desired input source at any time. To switch input sources, press the "Source" button on the front panel.

5.3 Interface Description

The on-screen display provides information on multiple windows (Win 1-4), showing input sources, output size, brightness, sound status, network port usage, and internal chassis temperature. The icons represent output size, brightness, sound, network port usage, and internal temperature.

Main Menu

The main menu includes the following options:

• 1. Net: Network port settings for load range and connection relationship of the sending card network port.
• 2. Screen layout: Sets the output screen and supports up to 4 screens displayed simultaneously.
• 3. Effect: Adjusts image sharpness, contrast, saturation, color temperature, brightness, and other settings.
• 4. Image capture: Captures the input source image and its coordinates.
• 5. Template settings: Saves current parameters as a template file for quick future settings.
• 6. Settings: Configures input source resolution, restores factory settings, sound management, key lock settings, and language management.
• 7. Firmware version: Displays the current firmware version.
• 8. Language: Allows for device language switching.

Net Settings

• 1. Screen setting: Configures screen width and height (pixels).
• 2. Output setting: Sets coordinates and range of the network port. Horizontal width: 256 (LED screen width). Vertical height: 128 (LED screen height). Horizontal start: Set parameter range = LED screen width - horizontal width. Vertical start: Set parameter range = LED screen height - vertical height.
• 3. Input setting: Manages the connection relationship of the receiving card. Currently, only standard universal mode is supported; complex relationships are not supported.

Screen Layout

Options include: Select image, Switch, Width, Height, X, Y, Save, Cancel. Note: Screen switch setting for screen 1 cannot be turned off. Horizontal starting value + horizontal width must not exceed the LED screen width. Vertical starting value + vertical width must not exceed the LED screen height.

Effect Settings

Adjusts image parameters:

• Brightness: 0-100, Default 100.
• Sharpness: 0-10, Default 5.
• Contrast: 0-100, Default 76.
• Saturation: 0-100, Default 50.
• Hue: Customizable color temperature (Warm, natural, cool), Default Warm.

Image Capture

Settings include: Screenshot, Switch, Width, Height, X, Y. When the cutoff switch is off, the knob cannot adjust width, height, or starting points. Cut width and height are limited to 128 (maximum input source dimension). Horizontal start range = Input source width - Cut width. Vertical start range = Input source width - Cut width. Note: If captured image size matches output image size, it's displayed point-to-point; otherwise, it's displayed in zoom mode.

Template Settings

Supports up to 8 template files. Existing templates can be replaced, deleted, and loaded. Options for non-existent templates also support saving. Supports 4 sets of universal resolutions and custom resolution settings.

Other Settings

Includes Lock function, Setting times (default 60), Automatically return, Set automatic return time (default 600), Signal detection switch, Type-C input, and WIFI password reset. The button lock delay switch supports up to 3600 seconds; exceeding this time automatically locks the buttons. To unlock, press and hold ESC and FREEZE keys for 3 seconds.

Image Rotation

Supports normal display, horizontal mirroring, horizontal vertical mirroring, and vertical mirroring.

Language Selection

Supports English and Chinese.

Firmware Version

Displays firmware details: MCU V8.03.25, DSP V1.01.43, FPGA1 40.07.02, FPGA2 40.07.02, Wi-Fi 1.10.14, dated 2023/9/4 9:37:30.

6 Digital Function Description

When inputting numbers for settings like screen width and height, the keyboard reuses relevant buttons. During number input, only the reused button and ESC are functional; the knob can be used, but other key functions are prohibited until exiting. Key reuse is as follows:

Description of Status Lights for Buttons

When a button is pressed, its light turns on and turns off when released, unless other requirements apply.

Button Functionality Details

• If the input source of a window is DVI1/DVI2/HDMI 2/HDMI 3/DP and no signal is present, the indicator flashes off at 125ms intervals until a signal is detected. If the signal is lost midway, it continues to flash.
• When the BLACK button is pressed, all lights (DVI1, DVI2, HDMI1, HDMI2, HDMI3, DP) turn off, and the BLACK light remains on. Pressing the BLACK button again turns off the BLACK light, and the status reverts based on the input source light.
• After pressing the FREEZE button, its light remains on and turns off upon the next press.
• The illuminated button indicates the currently selected window (WIN1, WIN2, WIN3, WIN4). To switch windows, the input source's button light must synchronize with the current window's input source type.
• On power off and restart, the following states are saved: current window's input source type, status of the BLACK light, status of FREEZE, and selection status of WIN1, WIN2, WIN3, and WIN4.
