Default: Good Read
Options: 0 = Disabled
1 = Match
2 = Mismatch
3 = Any Good Read
4 = Only If All Good Reads
Usage: It is useful when an application only needs to use the discrete outputs
and can allow the reader 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.
Definition: When set to Disabled , the reader will not transmit any data that is generated
during a read cycle (symbols, No-Reads, etc.)
Usage: 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.
Definition: When set to Match , the reader transmits symbol data whenever a symbol
matches a master symbol. However, if Matchcode Type is Disabled , it
transmits on any good read.
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 reader transmits symbol data whenever the
symbol data information does NOT match the master symbol.
