PCIe x1 expansion card providing two DB9 RS232 serial ports at 921.6Kbps for industrial control.
Connecting legacy industrial equipment to modern servers often fails due to missing native serial interfaces, causing integration delays in automation environments. This PCIe serial card solves connectivity gaps by adding reliable RS232 ports directly to standard PCIe slots.
Based on the EXAR XR17V352 controller, the LRUA9252H-232 delivers 921.6Kbps per port, ensuring fast data transmission for modulation and control signals. Its PCIe 2.0 x1 interface guarantees compatibility across x1 to x16 slots, enabling flexible deployment without wasting valuable expansion resources.
Ideal for connecting printers, scanners, and industrial controllers, this adapter supports MSI interrupts and ASPM power management for stable operation. Unlike generic USB adapters, it provides dedicated hardware flow control and 256-byte FIFO buffers for mission-critical serial communication reliability.
Expands system connectivity with two standard DB9 RS232 serial ports for legacy device integration.
Supports industrial standard 16C450/16C550 UART with data rates up to 921.6Kbps per port.
Compatible with all PCIe slot sizes (x1, x4, x8, x16) supporting PCI Express 2.0 Gen 1.
Features 256-byte TX/RX FIFO buffers with onboard hardware and software flow control.
Supports PCI Power Management 1.2, ASPM, traditional interrupts, and MSI interrupts.
