Sybausa SI-PEX15037 PCIe 2X Port Serial DB9 Card, WCH CH382

The SYBAUSA SI-PEX15037 is a PCI-e 2-port serial DB9 card designed to add two RS232 compatible serial ports to a host system. It addresses the challenge of integrating older serial-based hardware with modern systems that often lack built-in serial ports. The card utilizes a WCH CH382 chipset and is fully compliant with PCI-e Base Specification, Revision 1.0a, supporting PCI-e Power Management. Each serial port is a 16c450/550/Extended 550 compatible UART, offering bi-directional speeds from 50bps to 16Mbps and supporting various serial formats and flow control methods. It includes both a low-profile and a full bracket for installation flexibility.
