H-2 Symbol Data Output
• Note: 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.
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.
Note:
A No-Read can still be transmitted if
Enabled
.

A No-Read can still be transmitted if
Enabled

H-2-1 Symbol Data Output Status
Usage: Useful when the host needs symbol data only under certain conditions.
Definition: Defines the conditions under which decoded symbol data is transmitted to
the host.
Serial Cmd: <
K705, symbol data output status ,when to output,symbology identifier
status
>
Default: Good Read
Options: 0 = Disabled
1 = Match
2 = Mismatch
3 = Any Good Read
4 = Only If All Good Reads
Disabled
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.)
Match
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.
Mismatch
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.
Any Good Read
Usage:
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.
Definition: 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.
