Trigger

When selected, the EZ Button acts as a trigger for the scanner 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 End of Read Cycle Mode is set to Timeout.
In External Edge:	As with External Level, External Edge allows a read cycle to be initiated by pressing the EZ Button, but unlike External Level, the read cycle ends with a good read output, a timeout, or a new trigger.
