The SUNIX IPC-E2204S is an industrial-grade PCI-Express serial expansion card that provides four independent RS-422/485 communication ports, ideal for robust and high-speed serial data transmission in demanding environments. Each port supports baud rates from 50 bps up to an impressive 921.6 Kbps, leveraging a SUNIX SUN2410 controller compatible with 16C950 UART standards. The built-in 128-byte hardware FIFO buffer ensures smooth, reliable, and collision-free data flow.

This card is designed with advanced surge and electrostatic discharge (ESD) protections, including 2KV surge protection compliant with IEC-61000-4-5 Level 3 and ±15KV ESD protection per IEC-61000-4-2, safeguarding sensitive equipment. The RS-422/485 ports feature an automatic detection and switching mechanism, eliminating the need for jumpers or software configuration.

Featuring AHDC/CS™ technology, this PCIe 2.0 x1 card delivers collision-free communication alongside on-chip hardware auto flow control to prevent data loss during high-throughput operations. It supports plug-and-play installation with BIOS-assigned I/O addresses and IRQs, simplifying system integration.

Certified by CE, FCC, VCCI, BSMI, and RoHS standards, and backed by Microsoft WHQL driver approval, the IPC-E2204S offers broad OS compatibility including Windows and Linux. The package includes a DB44-to-4xDB9M cable (40 cm), a standard full-height ATX bracket, and an additional low-profile bracket to fit varied PC chassis configurations.
