DEC-Professionan300SeriesRealTime-Solutions

This document describes the Digital Equipment Corporation (DEC) Real-Time Interface (RTI) for their Professional 300 Series computers.

The RTI is designed to transform the Professional 300 into a personal workstation for laboratory environments. Its primary function is to automate instrument control and data collection from various laboratory devices, enabling users to monitor research instruments, collect, analyze data, and generate reports/graphics.

Key features of the RTI include its integration of three widely used I/O interfaces onto a single module:

• Two EIA RS232/423-compatible serial asynchronous ports.
• One IEEE-488 (GPIB) general purpose interface bus port.
• One 24-bit wide TTL-compatible digital parallel port.

The document highlights benefits such as simplified application development, easy installation, and complete Digital hardware/software servicing. Software support is provided through the Professional Real-Time Interface Library (PRTIL), which offers high-level subroutines for controlling the RTI's functionality. The RTI is user-installable and compatible with any Professional 300 Series system, with external cabling and connector options available for concurrent use of all interface types. Detailed specifications for each port, environmental, and electrical requirements are also provided.
