What is LED display control card?

LED display control card is the core component of LED graphic display, responsible for receiving the screen display information from the serial port of the computer, into the frame memory, according to the partition drive mode to generate the serial display data and scanning control timing required by the LED display. the effect of the LED display screen is related to it.

What are the classifications of LED display control card?

It can be divided into three categories: single and double color control card, multi-color control card and full color control card.

What should I pay attention to when using LED display control card?

Different brands of control cards and corresponding installation software are different. The same brand is also divided into different models, the function is very different. Small area of monochrome screen commonly used simple non-partitioned control card, cost-effective; while the area is slightly larger can use partitioned control card, the price is higher.

What are the connection methods of LED display control card?

Control card and computer connection: network port (TCP/IP), serial port (RS232, RS485), U disk conduction, GPRS wireless connection, Zigbee wireless connection and other major ways.

How to choose the LED display control card?

First of all, understand the specifications of the LED display, size, calculate the number of points, know the effect you need, is synchronous, or asynchronous, need secondary development; Then, determine the synchronous and asynchronous, determine the effect, determine the range of points, determine the range of prices, and finally determine the card; control card to choose the most suitable, not necessarily high price, good quality is the most suitable. Finally, the software is not suitable for themselves and their customers.

Can not find the LED display control card how to do?

1. Confirm that the control card is compatible with the software.

2. Check whether the connection line is off, loose, check and confirm that the serial line used to connect the control card with the control card mates, some control cards with straight-through (2-2, 3-3, 5-5) some control cards with (2-3, 3-2, 5-5).

3. Ensure that the control system hardware has been properly powered up. 4.

4. control card software and their choice of control card to select the correct product model, the correct transmission mode, the correct serial port number, the correct baud rate and the software provides the dial-switch map to correctly set the control system hardware address and baud rate. 5. if after the above checks and calibrations, the control system hardware has been properly powered up.

5. If after the above checks and corrections are still not loaded, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. To confirm whether to return the computer manufacturer or the control system hardware to return to the test.

6. If the fifth step is not convenient to carry out, please contact the manufacturer to provide technical support
