Trigger Mode
If the Trigger Mode is enabled, driving the TRIG pin on the host interface connector low activates a
decode session. The session continues until the barcode is decoded or decode session timeout occurs or
the active trigger signal is no longer present. For good decode, the engine transmits decoded data via
communication port. To activate another session, the Host needs to first negate the trigger, waits 20ms or
longer and then drive the TRIG pin low.
