Dual Serial Port Expansion: This PCIe to 232 DB9 serial port card delivers two independent RS-232 serial ports, enabling simultaneous connection of industrial devices such as PLCs, barcode scanners, POS terminals, and CNC controllers—ideal for system upgrades in automation, point-of-sale, and equipment integration without requiring motherboard replacement or external USB adapters.
Wide Compatibility: This 2 Port PCIe 232 DB9 serial port card supports 98SE through 11 (32/64-bit), multiple distributions including , CentOS, and Debian, and is fully compatible with standard PCIe x1, x4, x8, and x16 slots—ensuring plug-and-play on desktop PCs, industrial computers, and embedded systems without driver conflicts or manual configuration.
Advanced Chip Integration: This 2 Port PCIe 232 DB9 serial port card features the high-performance UART controller with 256-byte hardware FIFO buffering per port, reducing CPU overhead and data loss during high-speed transmission—delivering stable, low-latency even under sustained 115200bps baud rate across diverse hardware platforms.
Versatile Bracket Design: This 2 Port PCIe 232 DB9 serial port card includes both full-height and low- mounting brackets, allowing seamless installation in standard ATX towers, compact 2U rackmount servers, and space-constrained industrial enclosures—no additional adapters or modifications required, maximizing deployment flexibility across enterprise, manufacturing, and IT infrastructure environments.
High-Speed Reliable Data Transfer: This 2 Port PCIe 232 DB9 serial port card supports configurable baud rates up to 115200bps with automatic control (RTS/CTS and XON/XOFF), precise timing accuracy, and ESD up to ±15kV—ensuring error-, noise- serial in electrically demanding environments like factory floors, data centers, and device interfaces.
