Introduction In the world of industrial computing, embedded systems, and legacy hardware integration, the WCH CH382L chipset plays a crucial role. Designed by Nanjing Qinheng Microelectronics (WCH), the CH382L is a high-speed, dual-port PCIe (PCI Express) to serial (UART) controller. It allows users to add two RS-232 serial ports to a computer via a PCIe slot, making it indispensable for connecting older serial devices—such as barcode scanners, industrial PLCs, POS systems, and network switches—to modern Windows 10 PCs.
A: The CH384L is a 4-port variant. Some drivers misidentify the chip. This is cosmetic and does not affect function.
A: Reseat the card. Check BIOS settings for PCIe native support. Disable "Legacy Serial Ports" in BIOS to free resources.
