What Is a Dual Monitor Video Card?

LED panel (LED panel) is a display screen that displays various information such as text, graphics, images, animations, quotes, videos, video signals, etc. by controlling the display mode of semiconductor light emitting diodes.

led display control card

The LED display screen has bright colors and strong three-dimensional sense. It is as quiet as oil painting and moving like a movie. It is widely used in stations, terminals, airports, shopping malls, hospitals, hotels, banks,

The basic components of an LED display are a display module, a control system (display control card),

Introduce the ACL-A control card of Beijing Jingxin Daan Technology Co., Ltd.

Take the BX series as an example 1. First, make sure that the control card and the screen are connected and power on to observe whether the screen is displayed normally (the default 1/16 scan display is normal). 2 Communication hardware inspection: 232 serial communication line is 2, 3, 5 direct connection, 485 serial communication line is 7 positive 8 negative 5 ground straight line (computer serial port needs to be connected to 232-485 conversion head). Baud rate 9600: white DIP switches B0, B1 are on the digital side, baud rate 57600: B1 is on the ON side, B0 is on the digital side (other dial switches P0-P7 are screen dials, all are on the digital Here the default screen is No.1, and the screen body is added by binary dialing). The jumper on the control card can adjust the 232/485 communication, and the level can be jumped. (Adjust the power supply and then power on the communication). 3 Software settings: Open the software and click 'Settings'-' Setting screen with '-'Password: 168'; Hardware settings, select the control group 'BX-?' ', Select the communication COM port, select the control card baud rate (corresponding to the control card); software settings, parameters corresponding to the unit board data, (for control cards with verification, software verification needs to be turned on during serial communication Set the window, press the ALT key and-key at the same time, open the verification in the pop-up window, press OK and then restart the software for communication). 4 Display settings: If the connection between the control card and the screen is abnormal, first check the hardware connection, such as: whether the cable is plugged in reverse, and whether the interface definition corresponds to the signal. Then check whether the scanning mode corresponding to the data direction of the module driver chip is loaded correctly and set correctly. If the display of the screen is abnormal under normal communication, set the scanning mode, and then select the data corresponding to the screen in the scan settings. After loading is successful (no need to download BX-A / BX-T if the display is normal), download Rongsi. (BX-E). For the scanning method of BX-C2 / M2 card, go to "Scan Settings" under the 3.0 software setting menu, enter three passwords of 8 and select the module unit board data direction, and then set the scanning method. 5 If the black screen data is dead, turn off all the white DIP switches on the control card and switch it to ON (the other side of the number), and watch the screen change after power on (default 1/16 scan). If it displays (screen parameter number: 0), reset the white DIP switch to reload and send.
