Scanner Parameters
Symbol Data Output
Symbol Data Output relates to data and should not be confused with Outputs 1, 2, and 3
listed in the Output Parameters which describe output states and functions.
Useful when the host needs symbol data only under certain conditions.
Defines the conditions under which decoded symbol data is transmitted to the host.
Note: Symbol Data Output Status, if set to Match or Mismatch, will not take effect
unless Matchcode Type is enabled and a master symbol is loaded into memory.
Symbol Data Output Status
Disabled
It is useful when an application only needs to use the discrete outputs and can allow the
scanner to do the decision-making. When Disabled, the host does not need the symbol
data and the communication lines are used only for setup and status checks.
When set to Disabled, the scanner will not transmit any data that is generated during a read
cycle (symbols, No Reads, etc.)
Match
Match is used in an application that requires specific symbol information and needs to
sort, route, or verify based on matching the specific symbol data.
When set to Match, the scanner transmits symbol data whenever a symbol matches a
master symbol. However, if Matchcode Type is Disabled, it transmits on any good read.
Note: A No Read can still be transmitted if Enabled.
Mismatch
Mismatch is typically used as a flag within the host system to prevent an item from being
routed in the wrong container.
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.
Good Read
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.
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.
