MS-820 Industrial Bar Code Scanner User’s Manual 8-9
8–Outputs
Mismatch
Good Read
When to Output Bar Code Data
As Soon As Possible
Definition: With Mismatch enabled, the scanner transmits bar code data when-
ever the bar code data information does NOT match the master label.
Note: A noread can still be transmitted if enabled.
Usage: Mismatch is typically used as a flag within the host system to prevent
an item from being routed in the wrong container.
Definition: With Good Read enabled, the scanner transmits bar code data on any
good read regardless of Matchcode Type setting.
Note: A noread can still be transmitted if enabled.
Usage: Good Read is used when an application requires all bar code data to
be transmitted. It’s typically used in tracking applications in which
each object is uniquely identified.
Definition: This command allows the user to choose when bar code data can be
sent to the host.
Serial Cmd: <Kloutput status,when to output>
Default: As Soon As Possible
Options: 0 = As Soon As Possible
1 = End of Read Cycle
Definition: Enabling As Soon As Possible causes bar code data to be sent to the
host immediately after a bar code 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 bar code data
needs to be moved quickly to the host, typically when the host is mak-
ing decisions based on bar code data.
