I/O Parameters
Good Read
Note: A No Read can still be transmitted if Enabled .
When to Output Symbol Data
As Soon As Possible
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
Usage: Good Read is used when an application requires all symbol data to be
transmitted. It’s typically used in tracking applications in which each
object is uniquely identified.
Definition: With Good Read enabled, the Imager transmits symbol data on any good
read regardless of Matchcode Type setting.
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 >
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.
