Ordering Code:


Komodo II CoaXPress 12G MXM is the best-in-class Frame Grabber, supporting the CoaXPress v2.1 standard. It can receive video streams from up to 4 CoaXPress links in single, dual, or quad modes. It can also be used for simultaneous capture from multiple cameras. Each link supports standard CoaXPress bitrates of up to 12.5 Gbps.

The frame grabber utilizes MXM compact standard. It is rugged and reliable and the four-corner mounting holes make it particularly resistant to shock and vibrations. These features make the Komodo II CoaXPress MXM ideally suited for industrial, defense, and aerospace Machine Vision Systems and applications.

The Komodo II CoaXPress 12G MXM can easily receive video streams on the CoaXPress links and transmit them to computer memory through the PCIe interface. This product also provides an external GPIO for machine control signals, such as triggers, timers, shaft encoders, exposure control and general I/O which can be controlled aside video stream acquisition. Our frame grabber uses standard Micro-BNC connectors as a CoaXPress interface to the camera. It utilizes PCIe Gen3 x8 links for communication with Host PC for video uploading and configuration.
