PCIe to 2-Port Serial Card, 9-Pin RS232 Adapter Card, Parallel & COM Port Expansion Card, WCH382L

The EZ-WCH382L is a PCI Express 2 serial card designed for POS and ATM applications, and it is the preferred choice for industrial automation system integrators. The EZ-WCH382L supports various mainstream operating systems, including Windows and Linux. Additionally, the two extended RS-232 serial ports can both support a communication rate of up to 230.4 Kbps and provide modem control signals to ensure compatibility with various peripheral serial devices. Since this card is "x1" PCI Express, it can be installed in various PCI Express slots (including 4x, 8x, 16x).
