    5. SOFTWARE COMPATIBILITY This section outlines the options relating to software that are available for the Owl 640 N. 5.1 XCAP Compatibility Raptor works closely with EPIX who integrate all Raptor camera models into their XCAP Imaging Software package. XCAP is the core plug and play software package that is offered with the Owl 640 N.

  • Page 10: Camera Setup And Requirments

    The amount of bandwidth required depends on the camera in-hand. The Owl 640 N uses a Base Camera Link interface which can be handled with a x1 PCIe bus and PIXCI EB1 from EPIX, providing roughly 200MB/sec maximum bandwidth.
