WCH PCI Express Parallel/Serial Driver 1.3.2014.3 (Windows 10 64-bit/32-bit)

The WCH PCI Express Parallel/Serial driver version 1.3.2014.3 provides support for PCI Express expansion cards equipped with WCH serial and parallel port controllers. These adapters add legacy COM (RS-232) and LPT connectivity to desktop computers, allowing older peripherals and industrial equipment to work with newer systems.

The driver is supplied as a Windows CAB package and supports both 32-bit and 64-bit editions of Windows 10.

Installing the WCH PCI Express Parallel/Serial Driver

The driver is distributed as a Windows Cabinet (.CAB) file rather than a conventional executable installer. Windows can extract CAB files without requiring additional software.

1. Download the CAB driver package and create a folder to extract its contents.

2. Right-click the CAB file and select Extract using a compatible archive utility, or use Windows Command Prompt:

   expand -F:* 041cac8b-7e9c-4830-a5d9-0824f5ddf1ff_2080eaad26cbefe2d164c7484c79d210e55911ee.cab C:\WCH-Driver

3. Open Device Manager and locate the WCH PCI Express Parallel/Serial adapter.
4. Right-click the device and select Update driver.
5. Select Browse my computer for drivers and point Windows to the extracted folder.
6. Follow the prompts to complete installation.

Note: The exact CAB filename was not provided, so the installation instructions use a generic filename. The correct INF should be selected from the extracted package.
