Check Digit Output Status (Code 39)

data security.
Definition: When enabled, the check digit character is read and compared along with
the symbol data. When disabled, symbol data is sent without the check
digit.
Note: With Check Digit Output Status and an External or Serial trigger
option enabled, an invalid check digit calculation will cause a No Read
message to be transmitted at the end of the read cycle.
