Parameter Overview
Chapter 7
Symbol Data Output
Useful when the host needs symbol data only under certain conditions.
Defines the conditions under which decoded symbol data is transmitted to the
host.
– Disabled
It is useful when an application only must use the discrete outputs and
can allow the code 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 code reader does not transmit any data that is
generated during a read cycle (symbols, No-Reads, and so on)
– Match
Match is used in an application that requires specific symbol
information and must sort, route, or verify based on matching the
specific symbol data.
When set to Match, the code reader transmits symbol data whenever a
symbol matches a master symbol. However, if Matchcode Type is
Disabled, it transmits on any good read.
– Mismatch
Mismatch is typically used as a flag within the host system to help
prevent an item from being routed in the wrong container.
With Mismatch enabled, the code reader transmits symbol data
whenever the symbol data information does not match the master
symbol.
• Default: Any Good Read
• Options: 0 = Disabled
1 = Match
2 = Mismatch
3 = Any Good Read
4 = Only If All Good Reads
IMPORTANT
Symbol Data Output Status, if set to Match or Mismatch, does not
take effect unless Matchcode Type is enabled and a master symbol is
loaded into memory.
IMPORTANT
A No-Read can still be transmitted if Enabled.
IMPORTANT
A No-Read can still be transmitted if Enabled.
