Note: More than one decode might in fact be required to qualify as a good read, depending
on how Decodes Before Output is set.
End of Read Cycle
Definition: This command allows the user to choose when symbol data can be sent to
the host.
Serial Cmd: < K705, symbol data output status, when to output, symbology identifier sta-
tus >
Default: As Soon As Possible
Options: 0 = ASAP 1 = End of Read Cycle
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 making decisions
based on symbol data.
Definition: Enabling As Soon As Possible causes symbol data to be sent to the host
immediately after a symbol has been successfully decoded.
Usage: End of Read Cycle is useful in timing-based systems in which the host is
not ready to accept data at the time that it is decoded.
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.
