Neousys PCIe-USB381F is an industrial-grade 8-port USB 3.1 Gen1 (formerly USB 3.0) frame grabber/host adapter card designed for machine vision applications. Featuring a x4 PCI Express Gen2 interface and four Fresco FL1100SX xHCI controllers, the PCIe-USB381F delivers up to 400 MB/s sustained data transfer rate per port with four USB3 cameras operating simultaneously, or a total bandwidth of 1600 MB/s when all eight ports are in use.

All eight USB ports are conveniently located on the card’s faceplate for easy and efficient cabling. Each port delivers a standard 900mA regulated 5V output, and can be configured via onboard jumpers to supply up to 1800mA for high-power USB3 devices. The card also supports software-programmable per-port power on/off control, allowing remote reset of connected devices for fault recovery.

With stable 400 MB/s data throughput per port, PCIe-USB381F meets the bandwidth requirements of most industrial USB3 cameras. Combined with reliable power output and flexible control features, it is ideal for a wide range of vision-related applications, including machine vision, factory automation, and medical imaging.
