A technique is described whereby parallel data communications are provided between an IBM Personal Computer (PC) and a robot controller so as to enable the computer to compute positional requirements in a realtime environment and then communicate the results to the robot manipulator within an acceptable time period. The concept described herein utilizes off-the-shelf circuitry, such as the ST4304 supplied by Applied Micro Technology Corp., so as to provide parallel input/output (I/O) hand-shaking communications, when operated in conjunction with the IBM AML (A Manufacturing Language) software program, as used in industrial and robotics control systems and the IBM PC. DIP (Dual Inline Package) switches are combined with the circuitry so that the user may select the addresses for responding to the parallel communications port.
