DAQcore: a General Purpose Data Acquisition CANbus Node Alberto D. Bolatto Radio Astronomy Lab, University of California, Berkeley This memo contains a detailed description of a general purpose data acquisition CANbus node developed by the author at the RAL. The planned uses of this node include the monitoring and control of the correlation water vapor radiometer, and the CARMA IF amplifier and related fiber optic components. The module is general enough, however, to be useful in many other applications.
