DVI2USB Duo Connection Diagram

Designed for those that require an external solution to capture high-quality and high-resolution dual-link DVI video signals, DVI2USB Duo is an industrial-grade frame grabber that captures video with resolutions of up to 2048×2048 (2560×1600 in widescreen mode) at transfer rates of up to 330 megapixels per second. DVI2USB Duo can achieve lossless capture rates of 60 frames per second at low resolutions, 8 to 30 FPS at 1920×1200, and 4.8 to 14 FPS at 2048×2048, depending on content being captured.

DVI2USB Duo transfers the captured video stream from DVI/HDMI video sources onto a computer using a USB 2.0 interface. The user then has the ability to record and/or transmit these images over public, private or broadband wireless networks. DVI2USB Duo is essential in enabling remote diagnosis of high resolution medical displays, air traffic control displays, control room monitors, and other applications in which a precise image of a high resolution video display source is required for accurate decision-making or replay.

As a portable, compact external device, DVI2USB Duo is easy to use and to transport. About the size of a small book, it is simple to set-up for any individual with basic knowledge of computers.

If you require a frame grabber with higher performance, please refer to DVI2PCIe Pro.
