Method for diagnosing conditions in a signal line

摘要

A system is disclosed for intelligently providing suggestions for solving problems encountered during installation and testing of complex electronic circuitry. A plurality of first outputs provide indications of non-selectable conditions of the system, such as conditions related to power supplies. A plurality of second outputs provide indications of conditions of signals coupled to the system, and a plurality of third outputs provide indications of selectable parameters, such as switch positions. These indications and conditions are monitored for incorrect conditions and are polled in an order determined by importance of the condition with respect to operation of the system. Responsive to an incorrect condition or indication being polled, the polling process is halted and a message is generated indicating how the incorrect condition or indication may be corrected.
