When to Output Symbol Data

As Soon As Possible

End of Read Cycle

Note: See “End of Read Cycle” on page 4-13 for options to end the 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 mode,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.
