PCIe to 2-Port RS232 Serial Card 9-Pin COM Port Expansion Adapter, WCH382L Chipset, Parallel Port Converter, PCI-E to DB9 Serial Interface Card for Desktop PC

Introduction

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