Abstract
A test system for testing the wiring configuration of a programming plug 10 for a gas turbine engine control unit 16 includes an array of multiplexers 28. The multiplexers concurrently acquiring one data bit from a prescribed data pin in each of several groups of data pins projecting from the plug. A computer operating under the authority of an executable computer program produces an incrementable selection signal to successively prescribe the individual data pins from which data is to be acquired. The system also includes standards against which the condition or validity of the wiring configuration is assessed. A display system, such as a video monitor reports the condition of the programming plug.
Claims12
A tester for examining a data plug, comprising:
- a circuit including a multiplexer array responsive to a selection signal for concurrently acquiring data bits from said data plug;
- a display system for reporting the condition of said data plug;
- and
- a computer communicating with said circuit and said display system for governing said circuit and for commanding said display system.
A tester for a turbine engine programming plug, said plug having two or more groups of data pins, each of said groups including two or more pins, comprising:
- an array of multiplexers for concurrently acquiring one data bit from a prescribed data pin in each of said groups of data pins;
- a computer operating under the authority of an executable computer program for receiving said data bits and for producing an incrementable selection signal for successively prescribing an individual data pin in each of said groups of pins from which said one data bit is to be acquired;
- a standard for assessing the condition of said programming plug based on said data bits;
- a display system, responsive to said computer program, for reporting the condition of said programming plug.
