Design of a Laboratory Computer Interface

Abstract

An interface for the LSI-11 computer was designed and implemented so that the computer supports data acquisition, data reduction, and equipment control. The design includes both hardware and software and addresses both parallel and serial input/output (I/0). The serial interface's hardware is simply a Serial Line Unit card. This card plugs into the LSI-11 bus and provides the signals necessary to interface EIA RS-232 compatible devices. A software utility was developed to allow communication with the serial device and to allow exchange of data files. Routines were written to allow serial I/O through a FORTRAN program. The interface's parallel hardware includes the general purpose laboratory interface system (GPLIS) architecture. In addition, hardware modules were designed to convert certain device's signal levels to TTL levels. Software utilities were developed to acquire and store parallel data and routines were written to allow parallel I/O through a FORTRAN program....
