Parameter Overview
Check Character Status
This option is not typically used, but it can be enabled for additional security in
applications where the host requires redundant check character verification. An
error correcting routine in which the check character is added.
Check Character Output Status
Check Character Output Status, added to the symbol, provides additional data
security. When enabled, the provided character is read and compared along with
the symbol data. When disabled, symbol data is sent without the check character.
Large Intercharacter Gap
Large Intercharacter Gap is helpful for reading symbols that are printed out of
specification. When enabled, the code reader can read symbols with gaps
between symbol characters that exceed three times (3x) the narrow element
width.
Fixed Symbol Length Status
When enabled, the code reader checks the symbol length against the symbol
length field. If disabled, any length is considered valid.

When the Check Character Output Status and an External or Serial trigger
option is enabled, an invalid check character calculation causes a No-Read
message to be transmitted at the end of the read cycle.
