The WCH CH382L is a highly reliable PCI Express dual-serial and single-parallel port controller chip widely used in modern computer systems. Since modern motherboards rarely include native parallel (LPT) or serial (COM) ports, expansion cards using the CH382L chip are essential for connecting legacy hardware like dot-matrix printers, CNC machines, programmers, and industrial automation equipment.
This is useful for deploying drivers across multiple industrial PCs.
