As Soon As Possible

End of Read Cycle

Note: See “End of Read Cycle Mode” on page 4-15 for options to end the read cycle.

Definition: Enabling As Soon As Possible causes symbol data to be sent to the

host immediately after a symbol has been successfully decoded.

Note: More than one decode might in fact be required to qualify as a

good decode, depending on how Decodes Before Output is set.

Usage: As Soon As Possible is useful in applications in which symbol data

needs to be moved quickly to the host, typically when the host is mak-

ing decisions based on symbol data.

Definition: Enabling End of Read Cycle means that symbol data does not get sent

to the host until the read cycle ends with a timeout or new trigger.

Usage: End of Read Cycle is useful in timing-based systems in which the host

is not ready to accept data at the time it is decoded.
