Abstract
Abstract A system wherein a voltage is applied in sequence to a plurality of terminals on a wired panel, and a computer is employed to scan all other terminals on the panel to determine where the applied voltage appears and does not appear, thereby establishing that connections exist between the terminal or terminals to which the voltage was applied and those scanned terminals where the voltage appeared. The computer then compares the resulting voltages with a master wire list and prints-out any wiring errors. The master wire list may be stored in the computer by the operator or the computer may be utilized to analyze an existing panel or wiring network to obtain the same.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
A system for testing the electrical connections among circuit points in a wired circuit comprising: a computer having input and output terminals; first means including a plurality of gating networks for coupling groups of said circuit points to said input terminals, one gating network being coupled between each circuit point group and a corresponding computer input terminal, and each of said circuit point groups having the same number of circuit points therein; second means including a series of switches corresponding in number to the number of circuit points in each of said groups; third means operated by said computer for selectively applying a test voltage to one of said circuit points; and fourth means coupled to said computer output terminals and to said switches and operated by said computer to cause said gating networks to sequentially apply signals to said computer input terminals representing the voltage conditions of successive circuit points in the series of each of said groups.
Claim 2
Independent Claim
159 words
A system for testing the electrical connections among circuit points in a wired circuit comprising: a computer having input and output terminals; first means including a plurality of gating networks for coupling groups of said circuit points to said input terminals, one gating network being coupled between each circuit point group and a corresponding computer input terminal, and each of said circuit point groups having the same number of circuit points therein; second means including a series of switches corresponding in number to the number of circuit points in each of said groups; third means operated by said computer for selectively applying a test voltage to one of said circuit points; and fourth means coupled to said computer output terminals and to said switches and operated by said computer to cause said gating networks to sequentially apply signals to said computer input terminals representing the voltage conditions of successive circuit points in the series of each of said groups.
Claim 3
Dependent Claim
54 words
The system defined in claim 1 wherein each gating network in said first means includes a fist series of impedances and diodes coupling each circuit point of the associated group to the associated computer input terminal and a second series of diodes coupling the impedances to a reference potential different from said test voltage.
Claim 4
Dependent Claim
39 words
The system defined in claim 1 wherein said computer is operated to compare successive voltage representations in the series of said groups with a stored set of signals representing the proper group output signals for a properly wired circuit.
Claim 5
Dependent Claim
36 words
The system defined in claim 1 wherein said groups are separated into a plurality of sets and additional switching means controlled by the computer are provided to switch the test voltage from one set to another.
Claim 6
Dependent Claim
23 words
The system defined in claim 1 wherein switching means controlled by said computer are provided for changing the value of said test voltage.
