Abstract or Summary
  • An advanced laboratory interfacing capability was developed for the Real-Time Digital Computer Laboratory in the Chemical Engineering Department. A stationary interfacing unit located beside the computer mainframe and two small remote units were designed, developed and thoroughly tested. These interfacing units permit experiments with a wide variety of analog and digital signals to be connected to the computer quickly and simply using standard patch cords and readily available cables and connectors. A complete software package was developed which corresponds to the industry standard routines to support all interface equipment in the laboratory. All routines are developed in assembly language in a form which can be executed by standard FORTRAN subroutine calls. A hierarchical computer structure was conceived and implemented using microcomputers communicating (9600 baud) with the NOVA minicomputer which can communicate (2400 baud) with the Oregon State University CYBER computer, all communications at high data rates. Cost-effective programming of microcomputers using a cross-assembler on the NOVA minicomputer was implemented. Microcomputer assembly language programs developed using the editing and disk storage capability of the NOVA are easily assembled and quickly downloaded (9600 baud) to the microcomputer by a cable interconnection. The microcomputer developments utilize the state-of-the-art technology and communication concepts and add tremendous potential flexibility for instructional and research users in the department. The current status and documentation of the Real-Time Digital Computer Laboratory establishes this facility as one of the most outstanding in the country.
