LED Display Configuration
According to the quantity of scan board, there’re two different modes for LED display configuration: No scan board cascaded mode or cascading scan board mode.
1) No scan board cascaded mode (one PSD100 Asynchronous card only) Switch to “Screen Config” page in Fig. 7-1, the interface of a No scan board cascaded mode is shown below in Fig. 7-12:

Read form HW

This is used for the application to read the LED display configuration information from the hardware.

2) Cascading scan board mode (PSD100 Asynchronous card cascading MRV300/MRV320 scan board)

The mode of the cascade receiving the card is divided into sending card mode and multi-display configuration. The former is asynchronous card without box carrier, equal to the sending card.
Multi-display configuration is usually used for dual panels. Both panels playing the same picture.
The multi-display mode does not support correction.
There are three LED display types: a simple screen, standard screen, and complex screen. These options will be shown at the top of each the Screen Configuration page. Choose a screen type before any configuration operation. Configurations for different types of screens will are as follows…

a) Simple Screen Configuration

Simple screen means each scan board drives the same pixel array, edit items below according to LED display status.

Sender Mode

If asynchronous card carries no box carrier, please tick this item

Multiple Screens

Tick this item to configure multiple panels

Read File

Used to load the LED display configuration settings from a file

Save File

To save the LED display configuration settings to a .scr file

Send to HW

To send LED display configuration settings to the connected PSD10 Asynchronous card


Used to save the settings to a FLASH chip to ensure the data won’t be lost if the hardware is powered off.


This designates the upper-left corner of a rectangular area of the computer display. The rectangle area of the computer display is called the mapping area. Content inside the mapping area will be shown on the LED display. The default location is (0,0), which is actually the upper-left corner of the computer display.

Virtual Mode

Specify the pixel mode of the LED display. The option could be a real pixel or virtual 3 LEDs or virtual 4 LEDs.

Scan Board Columns/Row

These are the number of columns and rows of the scan boards (receiving cards) array of the LED display.

Scan Board Width/Height

These two parameters in the Scan Board Info panel refer to the width and height of the pixel array driven by a scan board (receiving card). They must be set the same as those set in the Scan Board page.

b) Standard Screen Configuration

Configure scan boards connection routing manually, and each scan board could drive different pixel array.
