　　Distance control is an important technical parameter of the LED display control card. It refers to the distance between the control device (such as a computer, mobile phone, etc.) and the LED display. Understanding what this distance means and how to choose the right LED display control card based on it is crucial for ensuring smooth operation. This is a common question among many users, so let's go through it one by one.
What is the control distance of an LED display control card?
The LED display control card refers to the distance from the control terminal (such as a computer or mobile device) to the LED display, either through a serial cable, USB drive, or wireless connection like GPRS. The longer the control distance, the more complex the wiring becomes, and the higher the requirements for the system. Some special applications cannot be met by standard LED display control cards.
How to choose the type of LED display control card?
For short-distance applications, such as small screens within about 10 meters, a regular serial port or USB control card is sufficient. These types are easier to use and allow for simple program updates. For example, traffic signs, weather warning displays, and car advertisements often require wireless control due to their location or mobility needs. A LED wireless control card allows remote operation without physical cables, making it ideal for such scenarios.
Therefore, when choosing an LED display control card, it's essential to consider the specific needs of your project. If the distance between the control terminal and the screen exceeds 100 meters, a LED wireless control card would be the best choice, offering convenience and flexibility. Always assess the environment, required distance, and ease of maintenance before making a decision.
Drop Out Fuse Cutout is a kind of outdoor high voltage protection device, lt is connected with the incoming feeder of thedistribution transformer or distribution lines and primarily used to protect transformers or lines against the impact raised by shortcircuit, overload and switching current. The drop-out fuse cutout is composed of insulator support and a fuse carier, staticcontacts that are fxed on two sides of insulator support and moving contact installed on two ends of fuse carrier, The interior ofthe fuse carrier is the extinguishing tube while the exterior is made of phenolic compound paper tube or epoxy glass.
