Kunder som bruker LED -sceneskjermer er definitivt kjent med LED -skjermkontrollkort, but do you know some common problems with LED display control cards? This article will help you understand and solve a series of problems that arise with LED display control cards.
The LED stage screen control card is the core component of the LED graphic display screen, responsible for receiving image display information from the computer serial port, inserting it into the frame memory, and generating serial display data and scanning control timing required for the LED screen according to the partition driving mode. The effect of LED screen is related to it.
LED display control cards can be divided into three categories: single and dual color control cards, multi-color control cards, and full-color control cards
Precautions for using LED display control card
The control cards and corresponding installation software of different brands are different. The same brand is also divided into different models, with significant differences in functionality. A commonly used simple non partitioned control card for small monochrome screens, with high cost-effectiveness; For larger areas, partition control cards can be used, which are more expensive.
Connection method of LED display control card
The main connection methods between the control card and the computer include Ethernet port (TCP/IP), seriell port (RS232, RS485), USB flash drive transmission, GPRS wireless connection, Zigbee wireless connection, etc.
How to choose an LED display control card?
for det første, understand the specifications and dimensions of LED screens, calculate the number of points, and know the desired effect, whether it is synchronous or asynchronous, and whether secondary development is needed; Deretter, determine the synchronization and asynchrony, determine the effect, determine the point range, determine the price range, and finally determine the card; Choosing the most suitable control card does not necessarily mean that the one with high price and good quality is the most suitable. Endelig, is the software suitable for both oneself and the client.
What should I do if the LED display control card is not working properly?
1. Confirm that the control card is compatible with the software.
2. Check if the connecting cable is loose or detached, and verify that the serial port cable used to connect the control card is compatible with the control card. Some control cards use direct connections (2-2, 3-3, 5-5), while others use direct connections (2-3, 3-2, 5-5).
3. Ensure that the control system hardware is powered on correctly
4. Compare the control card software with the selected control card to select the correct product model, transmission method, serial port number, and baud rate. Set the address bits and baud rate on the control system hardware correctly by referring to the dip switch diagram provided in the software
5. If the above inspection and calibration still result in the inability to load, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. This will confirm whether the computer should be returned to the manufacturer or the control system hardware should be returned for testing
If the fifth step is not convenient, please contact the manufacturer for technical support.
