Frequently Asked Questions About LED Display Control Card
Estimated reading time: 1 minute
Introduction
When choosing a control card, it is crucial to consider factors such as specifications, size, effect, synchronicity, and the need for secondary development. Additionally, one must ensure compatibility with software and proper installation procedures. If issues arise, troubleshooting steps such as checking connections, confirming transmission modes, and addressing bits should be taken. With these considerations in mind, one can successfully operate and maintain their LED display with an appropriate control card.
What is the LED display control card?
The LED display control card is the core component of the LED graphic display. It is responsible for receiving the screen display information from the computer serial port, putting it into the frame memory, and generating the serial display data and scanning control required by the LED display according to the partition drive mode. Timing, the effect of the LED display screen is related to it.
What are the classifications of LED display control cards?
It can be divided into three categories: single and double-color control cards, multi-color control cards, and full-color control cards.
What should be paid attention to when using the LED display control card?
Different brands of control cards and corresponding installation software are different. The same brand is also divided into different models, and the functions are very different. Small-area monochrome screens often use simple non-partitioned control cards, which are cost-effective; while larger areas can use partitioned control cards, the price is higher.
What are the connection methods of the LED display control card?
The connection methods between the control card and the computer include: network port (TCP/IP), serial port (RS232, RS485), U disk conduction, GPRS wireless connection, Zigbee wireless connection and other main methods.
How to choose the LED display control card?
First understand the specifications and size of the LED display, calculate the number of points, know the effect you need, whether it is synchronous or asynchronous, and whether secondary development is required; then, determine the synchronous and asynchronous, determine the effect, determine the range of points, determine the price range, Determine the card; choose the right control card, not necessarily the one with high price and good quality. Is the software suitable for you and your customers?
What should I do if I can’t find the LED display control card?
a. Confirm that the control card is compatible with the software.
b. Check whether the connecting wire is loose or not. Check and confirm that the serial cable used to connect the control card matches the control card. Some control cards use straight-through (2-2, 3-3, 5-5) and some control cards Use (2-3, 3-2, 5-5).
c. Make sure the control system hardware is properly powered on.
d. Select the correct product model, correct transmission mode, correct serial port number, and correct baud rate according to the control card software and the control card you choose, and set the control system hardware correctly according to the dial switch diagram provided in the software The address bits and baud rate on the
e. If it still fails to load after the above checks and corrections, please use a multimeter to measure whether the connected computer or the serial port of the control system hardware is damaged. To confirm whether it needs to be returned to the computer manufacturer or send the control system hardware back for testing.
In conclusion,
LED display control cards are an essential component for the functioning of LED graphic displays. They come in different types that vary in color and partitioned capabilities. When choosing a control card, it is crucial to consider factors such as specifications, size, effect, synchronicity, and the need for secondary development. Additionally, one must ensure compatibility with software and proper installation procedures. If issues arise, troubleshooting steps such as checking connections, confirming transmission modes, and addressing bits should be taken. With these considerations in mind, one can successfully operate and maintain their LED display with an appropriate control card.
