Frequently Asked Questions

How many USB ports does the PCIe-USB381F have and what type are they?

The card has 8x USB 3.1 Gen1 ports, each using a panel-accessible Type-A USB3 connector. The ports are also compatible with USB 2.0/1.1/1.0 devices.

What is the bus interface and bandwidth of the PCIe-USB381F?

The card uses a x4 lane, PCI Express Gen2 interface, compliant with PCI Express Base Specification Revision 2.0, providing 2GB/s total bandwidth. Four Fresco FL1100SX xHCI controllers manage the 8 USB ports, delivering up to 400MB/s sustained transfer rate per port, or a total of 1600MB/s when eight cameras are connected simultaneously.

Does the PCIe-USB381F need external power?

No. It has an onboard 5VDC regulated power supply, so no external power connector is needed. Power is drawn from the PCI Express bus: maximal 2.0 A @ 3.3V and maximal 5.5 A @ 12V for all connected USB devices.

How much power can each USB port deliver?

Each port can deliver a standard 900mA regulated 5V output, or a user-configurable 1800mA output via onboard jumpers for devices requiring higher power consumption.

Can I turn individual USB ports on or off?

Yes. The PCIe-USB381F supports software-programmable per-port power on/off control, which can be used to reset cameras or other devices for fault recovery.

What operating temperature range does the PCIe-USB381F support?

The card is rated for 0 ~ 60°C operation with ambient airflow.

What operating systems does the PCIe-USB381F support?

The card supports Windows 7 and Windows 10 operating systems.

What are the physical dimensions of the PCIe-USB381F?

The card measures 117.7 mm (W) x 111.2 mm (H).

How-to Guides

Configure per-port current limit

Locate the onboard jumpers associated with each USB port's current limit setting.
Set the jumper to the standard 900mA position for typical USB3 camera power needs.
If a connected device requires higher power, set the jumper to the 1800mA position instead.

Use per-port power on/off control for device fault recovery

Install the appropriate software/driver support enabling per-port power control on Windows 7 or Windows 10.
Use the software control to power off the affected USB port when a connected camera or device faults.
Power the port back on via software to reset the device.

Details

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

All eight USB ports of PCIe-USB381F are accessible on the faceplate for easy cabling. Each port can deliver standard 900mA regulated 5V output to power USB3 cameras or user-configurable 1800mA output via onboard jumpers for devices that require higher power consumption. It also supports software-programmable per-port power on/off control to reset cameras or other devices for fault recovery.

The steady 400 MB/s data throughput satisfies the bandwidth requirement of most off-the-shelf industrial USB3 cameras. Pairing reliable 5 VDC power output and per-port on/off control, PCIe-USB381F can benefit a variety of vision-related applications such as machine vision, factory automation and medical imaging.
