Christopher J Center · 1986
This report describes the software interface of the Preston Scientific GMAD-4A Analog to Digital Converter with Digital Equipment Corporation's LSI-11/23 host computer. Digital's DRVII-B is used to provide communication between A/D converter and the host. Tested program examples are written in Macro-II Version 5.03b Assembly on the RT-II Version 5.2 operating system. Detailed program comments allow the high level language programmer to understand the sequence of steps necessary for data acquisition on the Preston Scientific A/D converter. Keywords: LSI-II Interface; GMAD-4A A/D Converter; System Level Programming; Preston Scientific GMAD-4A; Vibro-Acoustic Measurements; and Geokinetic Measurements.
