VGA2USB Pro Connection Diagram
Epiphan Systems VGA2USB LR™ is a frame grabber that acquires frames with up to 1280×1024 pixel resolution in a 24-bit palette. VGA2USB LR can achieve 1280×1024 lossless compression with up to 51 fps, depending on the content being captured.

Radar, ultrasound, navigational, security, and microscope imagery is best captured with the VGA2USB LR, as long as the source resolution is kept below 1280×1024. The VGA2USB LR is also excellent for capturing from sources with significant movement from frame to frame. If your application requires higher performance or resolution support, please refer to DVI2USB 3.0, VGA2USB PRO, VGA2Ethernet or DVI2PCIe.
