The Viper-Quad is a single slot, high speed video acquisition device for the PCI-bus. It features four independent acquisition channels each comprised of an analog-to-digital converter, synchronization circuitry, anti-aliasing filter (optional) and input look-up tables. These four channels can be used to acquire images from four non-genlocked monochrome cameras. For synchronization purposes, each channel also features separate horizontal and vertical sync signals (I/O), trigger inputs (optically isolated for protection from potentially hazardous voltages), trigger outputs, exposure control output and a strobe output. These permit each channel to acquire images from four completely independent cameras.

Targeted at machine vision applications using multiple cameras, the Viper-Quad can be used to acquire multiple views of the same object (360 degree inspection) or can be used to acquire images of multiple objects on a production line.

The Viper-Quad can transfer images to host memory via the host PCI-bus, or across the 200MB/s Coreco Auxiliary Bus (CAB) to the Mamba for embedded processing. Available in two versions, the Viper-Quad comes mounted with four acquisition channels, or for more cost sensitive applications, with two acquisition channels.
