Trigger

When selected, the EZ button acts as a trigger for the Imager to start and end read cycles. All other button operations are inactive.

In External Level:	The read cycle endures for as long as the EZ button is pressed, unless a timeout occurs and Timeout is enabled for End of Read Cycle.
In External Edge:	As with Level, Edge allows a read cycle to be initiated by pressing the EZ button, but unlike Level, the read cycle ends with a good read output, a timeout, or a new trigger.
