Method and apparatus for selectively monitoring input
First Claim
1. An apparatus for selectively receiving data from one of a plurality of sources, comprising:
- a plurality of sensor means for producing sensor signals in response to sensed parameters;
instrument means for receiving a first group of one or more of said sensor signals via a wire harness;
control means for receiving a second group of one or more of said sensor signals and responsively delivering said second group to said instrument means via a communication link; and
processing means for determining whether one of said plurality of sensor signals is being delivered via said wire harness or said communication link and for responsively monitoring one of said wire harness and communication link.

Abstract
Instruments, for example monitoring and diagnostic systems, are often designed to operate in connection with a variety of machine types. Advantageously, the instrument may receive data for each parameter from either the sensor directly or from another controller depending on the machine to which it is connected. The subject invention provides a method and apparatus for selectively receiving data from one of a plurality of sources. A plurality of sensors produce signals in response to sensed parameters and deliver a first group of one or more signals to an instrument via a wire harness. A control receives a second group of one or more of the sensor signals and responsively delivers the second group to the instrument via a communication link. A processor determines whether one of the plurality of sensor signals is being delivered via the wire harness or the communication link and responsively monitors one of the wire harness and communication link.
