Imperx Inc. in Boca Raton, Fla., is introducing the CoaXPress point-to-point serial communications link for high-resolution digital still-image and video cameras in aerospace and defense applications. The CoaXPress digital camera interface provides six gigabits per second and offers a coax cable slip ring for 360-degree camera rotation. The camera interface can help systems integrators achieve real- time image acquisition. It transmits video and connects cameras to frame grabbers through a standard 75-ohm coaxial cable. The interface also provides a 20-megabit-per-second uplink for communications and control. CoaXPress protocols provide for automatic link, camera, and host setup, and the camera interface can provide power to the camera over the coax cable. Available power is a nominal 13 watts at 24 volts. Short circuit protection is available.
