to the host.
Serial Cmd:
<
K705,
symbol output status,
when to output
>
Default:
As Soon As Possible
Options:
0 = As Soon As Possible
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.
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:
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.
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.
