Trigger Mode
If the Trigger Mode is enabled, receiving a valid trigger signal activates a decode session. The session continues until the
barcode is decoded as long as the trigger signal remains valid; the session stops when the signal becomes invalid. For good
decode, the engine transmits decoded data via communication port. To activate another session, the Host first terminates
the trigger signal, waits 20ms or longer and then makes the signal valid.
Trigger Mode
Auto Mode
If the Auto Mode is enabled, the engine activates a decode session every time it detects a change in ambient illumination.
The decode session continues until the barcode is decoded or the Decode Session Timeout occurs.
Receiving a trigger signal can also activate a decode session. The decode session continues until the trigger signal
becomes invalid or the barcode is decoded or the Decode Session Timeout occurs. The trigger signal needs to be
terminated before the engine is able to monitor ambient illumination again.
