Abstract: Presently disclosed output modules may be removably and directly connected to a vehicle gauge. For example, the output module may be directly mounted on or plugged into the back of the gauge, such as by using the existing mounting bosses of the gauge. Disclosed output modules may be used with existing micro-processor-controlled gauges to send a desired switch signal to an external device, such as a warning light or a kill switch, when measured data hits a trigger point. Prior to attachment of the output module, the end-user may program the gauge via connection to a computer or other device, in order to set the desired trigger point or threshold value. Once the gauge is programmed with the desired trigger point, the output module may be attached to the back side of the gauge and may be wired to the external device to be controlled.

Abstract: A system (102) and method for controlling the operation of an engine test apparatus (104) during a test cycle is provided. The system (102) includes an operator interface (106) for producing a control mode signal and a plurality of setpoints. The system (102) also includes a test controller (108) for receiving the control mode signal and the plurality of setpoints and responsively operating the engine test apparatus. The test controller (108) senses operating characteristics of the engine test apparatus (104). The test controller (108) also selectively operates engine test apparatus parameters in accordance with the control mode signal.
