,
the host does not need the symbol data and the communication lines are
used only for setup and status checks.
Definition: When set to Disabled , the scanner will not transmit any data that is generated
during a read cycle (symbols, No Reads, etc.).
Usage: Match is typically used to route items with the same identifying data to the
same location.
Definition: With Match enabled, the scanner transmits symbol data whenever the
symbol data information matches the master symbol.
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
Mismatch
enabled, the scanner transmits symbol data whenever the
symbol data information does NOT match the master symbol.
Note
: A No Read can still be transmitted if enabled.
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 scanner transmits symbol data on any good
read regardless of Matchcode Type setting.
Note : A No Read can still be transmitted if enabled.
