Epiphan VGA2USB LR
1280x1024 30FPS
This frame grabber has 16MB RAM on board, FPGA and Philips VGA ADC and acquires frames with up to 1280×1024 pixel resolution in a 24-bit palette. Because FPGA and 16MB RAM lossless compression is performed on board with normal utilization USB bus bandwidth, VGA2USB LR can achieve 1280×1024 lossless compression with at least 30 fps.
The VGA2USB LR is best suited for industrial, medical, scientific, and military applications where reliability and security is a must. About the size of a box of paperclips, the VGA2USB LR’s solid casing is made entirely of aluminum.
Radar, ultrasound, navigational, security, and microscope imagery is best captured with the VGA2USB LR, as long as the source resolution is kept below 1280 x 1024. The VGA2USB LR is also excellent for capturing from sources with significant movement from frame to frame.
Technical Specifications
Interface Supports USB 2.0 and USB 1.1 buses. Performance of the VGA2USB LR device will be significantly downgraded, however, when connected to a USB 1.1 bus.
