The LED display control card is the core component of the LED graphic display. It is responsible for receiving the display information from the serial port of the computer, and is placed into the frame memory. The serial display data and scanning control required for the LED display are generated according to the partition drive mode. Timing. The effect of the LED display screen is related to it.
LED display control card which classification?
Can be divided into single and double color control card, colorful control card, full-color control card three types of LED display control card should pay attention to what?
Different brands of control cards and corresponding installation software are different. The same brand is also divided into different models, the function varies greatly. The small area of ​​the monochrome screen is usually a simple non-partition control card, cost-effective; and a slightly larger area can use the partition control card, the higher the price.
What are the LED display control card connection methods?
Control card and computer connection methods include: network port (TCP / IP), serial port (RS232, RS485), U disk conduction, GPRS wireless connection, Zigbee wireless connection and other major methods.
How to choose LED display control card?
First understand the LED display size, size, calculate the points, know that their needs are synchronous or asynchronous, do not need secondary development; then, determine the synchronous asynchronous, determine the effect, determine the point range, determine the price range, Finally determine the card; the most appropriate choice of control card, not necessarily the high price, good quality is the most suitable. Finally, the software is not suitable for yourself and customers.
Can't find the LED display control card?
1. Make sure the control card is compatible with the software.
2. Check if there is any loose or loose connection cable. Check and confirm that the serial cable used to connect the control card is with the control card. Some control cards use direct (2-2, 3-3, 5-5) control. Card use (2-3, 3-2, 5-5).
3. Ensure that the control system hardware is properly powered up.
4. Select the correct product model, the correct transmission method, the correct serial port number, the correct baud rate and compare the control card software with your own control card to correctly set the control system hardware against the dial switch diagram provided in the software. The address bit and baud rate.
5. If the above check still occurs and the load still does not appear after calibration, use a multimeter to measure if the serial port of the connected computer or control system hardware is damaged. To confirm whether the computer manufacturer should be returned or return the control system hardware to the test.
6. If the fifth step is inconvenient, please contact the manufacturer to provide technical support. If you would like to know more about the LED display control card price, installation and setup, please contact the staff of our company, welcome to communicate!

The spotlights can be placed around the ceiling or above the furniture, in the wall or in the skirting line.
The light directly shines on the household items that need to be emphasized, so as to highlight the subjective aesthetic effect and achieve the artistic effect of outstanding emphasis, unique environment, rich levels, rich atmosphere and colorful.
