The drivers provided on this page are for JP PCI serial port (COM4), and most of them are for Windows operating system. Before downloading the driver, please confirm the version number of the operating system installed on the computer where the driver will be installed. If the system version number does not meet the driver requirements, it may cause some unexpected problems. In the case of determining the operating system version number, it is recommended to download the 5-star driver first.
In addition, as long as your downloaded driver version can make the system work normally and stably, you don't have to excessively pursue the latest version of the driver. This is because the new version of the driver is to solve some BUGs in extreme cases, or to improve a little bit of hardware performance, but it may also bring some new unpredictable problems.
Many hardware names are usually named after the chip model, and each chip model has its own dedicated driver, so as long as you know the chip model used by the hardware, you can find the right driver. For example, if your graphics card is named: "AMD Radeon RX 580", while actually the core chip model used is: "Radeon RX 580", then enter "Radeon RX 580" or "RX 580" to find the driver.
