This PCIe card expands a desktop computer's connectivity by adding four RS-232 serial ports through a single PCI Express slot. It is ideal for users who need to connect legacy or industrial devices that rely on serial communication, such as point-of-sale systems, security equipment, or testing instruments. The card uses a 16C550 UART chip and includes a 256-byte FIFO buffer to enhance data transfer efficiency, especially in multitasking environments. It supports a wide range of operating systems, including various Windows versions and Linux kernels 2.6 and later.
The card is compatible with desktop PCs that have an available PCIe slot and works with both 32-bit and 64-bit versions of Windows from XP to Windows Server 2016. It also supports Linux but lacks official support for that platform. Users should ensure their system meets these requirements before installation. The included driver CD and installation guide simplify setup, though Linux users may need to seek additional resources for configuration.
The card features a compact design suitable for standard desktop cases with PCIe slots. It uses standard materials for durability and includes all necessary components for immediate use. The 9-pin serial ports are designed for compatibility with a wide range of industrial and legacy devices. Its performance is optimized for environments where multiple serial devices may be connected and operated simultaneously.
The package includes the PCIe card itself, a driver CD, and an installation guide. No additional tools or software are required for basic installation, though users may need to download updated drivers from the manufacturer’s website for newer operating systems. The card is not compatible with laptops or systems without a PCIe slot.
