PCI 2-Port 9-Pin RS232 Serial Card 550 Value

This PCI card adds two 9-pin serial ports to a desktop computer with a PCI slot, allowing connection of devices like modems, PDAs, and high-speed serial peripherals. It is designed for systems that need extra serial connectivity without the need for external adapters or dongles. The card supports both 32- and 64-bit systems and works with PCI, PCI-X, and 3.3V/5V slots, making it compatible with a wide range of older and mid-range desktops. It is ideal for users who rely on legacy serial devices or industrial equipment that still uses RS232 communication.

The card features two high-speed 16550 UART serial ports capable of data transfer rates up to 16Mb/s, ensuring fast and reliable communication with connected devices. It includes IRQ sharing to minimize conflicts and deep FIFO buffers to reduce CPU load during high data transfers. These features make it suitable for environments where multiple serial devices are used simultaneously without performance degradation. The card also supports full compatibility with DOS and various Windows operating systems, ensuring broad software support.

Installation is straightforward as it uses standard PCI form factors and requires no special configuration beyond standard Plug and Play setup. The card is backed by a 2-year limited warranty from SIIG, providing users with confidence in its reliability. It meets several industry standards including PCI v2.2, RoHS, FCC Class B, and CE approvals, ensuring compliance with both performance and safety regulations.

The design is compact and built for internal use within a desktop case. It does not include external housing or connectors, so it must be installed directly into a PCI slot. Users should ensure their system has an available PCI slot before purchasing. No additional drivers are required for basic functionality, as it works with standard Windows and DOS software out of the box.
