Development of a Device for the Incorporation of Multiple Scanivalves into a Computer-Controlled Data System.

摘要

A controller (designated HG-78K) was built to permit manual and computer-directed acquisition of pneumatic data from multiple Scanivalves. The controller incorporated a low cost digital electronic circuit which was designed as a peripheral device on the Hewlett-Packard Interface Bus (HP-IB) to enable computer interrogation of port addresses of multiple Scanivalves. Computer programs were written in BASIC and FORTRAN languages and operation of the system was verified using HP-9830A and HP-21MX computers. (Author)
