Sunix 5027AL PCI-E Expansion Card

SUNIX 5027AL PCI-E Expansion Card: High-Performance RS232 Connectivity

Elevate your system´s connectivity with the SUNIX 5027AL, a professional-grade PCI Express expansion card designed to provide robust and reliable serial communication. Engineered for performance-driven applications, this card is the definitive solution for integrating legacy or industrial RS232 devices with modern computer systems. It seamlessly adds two high-speed RS232 serial ports through a single PCI Express slot, making it an ideal choice for industrial automation, point-of-sale systems, scientific instrumentation, and any environment demanding stable, high-throughput data transfer.

The core of the SUNIX 5027AL is its powerful, proprietary SUNIX SUN2410 UART controller. This advanced controller ensures maximum performance and reliability while minimizing host CPU load, allowing your system to handle other critical tasks without interruption. One of the standout benefits of this design is the generous 128-byte hardware FIFO (First-In, First-Out) buffer for both transmitting and receiving data. This substantial buffer prevents data loss during high-speed communication and ensures smooth, consistent performance, even under heavy I/O workloads. It guarantees that every byte of data is captured and transmitted accurately, which is crucial for data-sensitive applications.

Built for durability and operational longevity, the SUNIX 5027AL incorporates robust ±15KV ESD protection on all serial signal pins. This industrial-strength protection safeguards the card and your computer from electrostatic discharges, power surges, and other electrical hazards common in commercial and factory settings. This feature provides peace of mind and ensures system stability over the long term. Its versatile low-profile form factor allows for installation in a wide range of chassis, from standard tower PCs to compact, small form factor (SFF) systems, offering exceptional flexibility for system integrators. As a premier choice among Expansion cards for serial connectivity, it combines performance with versatile deployment options.

Main Features:

Experience superior serial communication powered by the high-performance SUNIX SUN2410 native PCI Express UART controller. This card delivers two independent, fully-functional RS232 serial ports, enabling simultaneous communication with multiple devices. It achieves exceptional data transfer speeds of up to 921.6 Kbps per port, accommodating even the most demanding peripherals. The card’s design supports comprehensive hardware (RTS/CTS) and software (XON/XOFF) flow control to manage data traffic efficiently and prevent buffer overruns. It offers broad compatibility with most major operating systems, including various versions of Windows, Linux, and QNX, ensuring seamless integration into your existing software environment. The intelligent PCI Express Interface automatically selects the appropriate IRQ and I/O address, simplifying installation and preventing hardware conflicts.
