3 = Any Good Read
4 = Only If All Good Reads
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.
When set to Disabled, the reader will not transmit any data that is generated
during a read cycle (symbols, No-Reads, etc.)
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 reader transmits symbol data whenever a symbol
matches a master symbol. However, if Matchcode Type is Disabled, it
transmits on any good read.
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 reader transmits symbol data whenever the
symbol data information does NOT match the master symbol.
Any 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 Any Good Read enabled, the reader outputs symbol data for any
qualified symbol in the read cycle regardless of Matchcode Type setting. No
Read is output if no symbols are qualified.
