Syba SY-PCI15027 32-Bit PCI Card with 4 Serial Ports and IOC845 Chipset

This is a PCI expansion card designed to add four serial ports to a computer system. It is ideal for users who need to connect multiple serial devices such as modems, industrial equipment, or legacy peripherals that rely on RS-232 communication. The card uses the IOC845 chipset and includes a 16C550 compatible UART with 16-byte FIFO buffers for efficient data transfer. It supports fast data rates up to 1 Megabyte per second and is compatible with 32-bit PCI bus systems following the PCI 2.1 specification. The card automatically detects and configures IRQ and I/O addresses during installation, simplifying setup for most users.

The card features four DB9 serial port connectors and comes with a fan-out cable for connecting external devices. It supports PCI IRQ sharing, which helps conserve system resources by allowing multiple expansion cards to share interrupt lines. This makes it suitable for systems with limited interrupt availability. The card does not support legacy address remapping, so it may not work in older systems that require manual configuration of I/O addresses. It is compatible with Windows 2000, Server 2003, XP, and Vista operating systems.

Installation is straightforward as the card is plug-and-play, requiring minimal user intervention. However, users should ensure their computer has an available PCI slot before purchasing. The card is not compatible with newer systems that use PCIe slots instead of PCI. It is best suited for older desktop computers that still use traditional PCI architecture. No additional drivers are required for basic functionality, but advanced features may need specific software support.

The card is built for reliability and performance in environments where multiple serial connections are needed. It is commonly used in industrial automation, telecommunications, and data acquisition systems where legacy devices still rely on serial communication. Users should be aware that it does not support modern operating systems like Windows 7 or later versions, which may limit its usefulness in newer setups.
