The keyword references system driver packages and update files for multi-port expansion hardware utilizing the WCH CH382 / DH382 controller chipset . This hardware bridge converts a computer's PCI-Express (PCIe) bus line into dual RS-232 serial DB9 communication ports (COM ports) or parallel printer ports. Nanjing Qinheng Microelectronics (WCH)
Before diving into the update process, it's helpful to understand what this hardware does and why its driver is so important. The PCIE DH382 Serial Port Card is a PCI Express expansion card designed to add two independent serial (COM) ports to a desktop computer. While modern computers rely heavily on USB and other high-speed connections, many industrial and scientific devices still use the older, yet reliable, RS-232 serial port. These include:
Mass spectrometers, medical imaging panels, and older digital multi-meters. Stable raw hex data translation via the 16C550 UART spec. Resolving Driver Errors & Yellow Exclamation Marks : Operates over a single-lane PCIe (x1) configuration at a 2
It is often grouped with the WCH CH382L chipset. Drivers may be listed under names like CH35XDRV.EXE or specific DH382 chipset folders on manufacturer support sites. 2. Vivitek DH382 (Projector) Go to product viewer dialog for this item.
