Abstract
A trouble-shooting system for computer-controlled machinery includes a portable programmable testing unit. The unit includes: a CPU; A/D and D/A converters connecting the CPU to a voltage probe, for either measuring voltages on the machine or generating test voltages to be applied to the machine; a voice synthesizer with headphones, and a text line display, for instructing the user; a keypad for the user to respond; a card slot for accepting a memory card which holds the test program; and a data bus connector. The data bus from the machine's control computer is disconnected for the test and coupled to the testing unit, which tests the computer as well as electro-mechanical devices of the machine. The card may be dedicated to the machine and contain a maintenance history.
