A control diagram showing the Keck-PAD system can be described with two fundamental units, the detector head and the detector control computer. The detector head has an FPGA development board, the hybrid modules, support electronics and configurable hardware I/O. The detector control computer runs Camserver on a Linux platform and uses the Matrox Imaging Libraries (MIL). Two basic modes of communication between the detector head and the detector control computer are used, an ethernet connection for sending control and status packets, and a Cameralink (full configuration) connection that is used primarily for the transfer of raw imaging data from the detector head to the detector control computer. |
