Detailed Description

Class Definition CGPITriggerValue for LLRP parameter GPITriggerValue.

Document Reference LLRP Specification Section 10.2.1.1.1.2

Document Reference LLRP Specification Section 16.2.4.1.1.1.2

<p>This trigger is tied to an event on the General Purpose Input (GPI) of the Reader. The event is represented as a boolean type, and it is up to the internal implementation of the Reader to map exact physical event to a boolean type. For example, a 0 to 1 and a 1 to 0 transition on an input pin of the Reader could be mapped to a boolean true and a  boolean false event respectively.</p> 


<p>This trigger parameter has a timeout value field. The timeout is useful for specifying a fail-safe timeout when this trigger is used as a stop trigger. When the timeout is 0, it indicates that there is no timeout. When used as a start trigger, the timeout value 

SHALL be ignored.

<p>Readers that do not support GPIs 

SHALL return zero for numGPIs in the capabilities discovery. If the Client sets up the GPI trigger for such a Reader, the Reader SHALL send an error message for the ADD_ROSPEC message and not add the ROSpec.
