Capable of transferring data rates up to 921.6 Kbps per port, integrated with OXPCIe954 UART for enhanced data handling and flow control. Designed for integration within low-profile computer chassis and operates seamlessly with varied OS environments via standardized driver support. ## Platform This PCIe low-profile serial adapter provides four RS-422/RS-485 compliant ports for asynchronous data communication. It integrates into a host computer's PCI Express slot for industrial automation, data acquisition, POS systems, and embedded control. It facilitates communication with PLCs, sensors, and other serial devices in demanding environments. ## Application Four-port RS-422 or RS-485 serial communication adapter for PCIe bus systems enabling simultaneous multi-device connectivity in industrial automation, data acquisition, and process control environments. Supports full-duplex differential signaling for noise-immune long-distance communication up to 4000 feet at speeds up to 921.6 Kbps. Common applications include connecting PLCs, HMIs, barcode scanners, scientific instruments, CNC machines, and legacy serial equipment to modern computer systems. Utilized in factory automation, laboratory instrumentation, point-of-sale systems, security access control, and telecommunications infrastructure where multiple serial devices require reliable high-speed communication. ## Images - - - -
