Supports asynchronous full duplex serial communication over twisted pair or shielded cable, suitable for factory environments and home workshops. Powered by the XR17V358 series multi IO PCIe controller, implementing industry standard 16C550 UART channels to enable cost effective connections for industrial machines. Automatic IRQ address allocation simplifies system setup, while built in DCDC isolation power provides electrical isolation and helps protect against ground interference. Designed for engineers and IT professionals who need to integrate multiple serial devices into their systems in a seamless, reliable manner. Use scenarios: Connect and manage multiple serial devices such as PLCs, CNC controllers, barcode printers, and other industrial equipment from a PCIe host in a factory or workshop. Retrofit legacy equipment to work with modern PCs or industrial controllers that use PCIe interfaces, enabling easier data collection and control. Implement data logging, remote telemetry, or system monitoring in IT or industrial environments that require stable, isolated serial connections.
