G-6-2 Check Character Output Status (Code 39)
Usage: Check Character Output Status, added to the symbol, provides addi-
tional data security.
Definition: When enabled, the check character character is read and compared along
with the symbol data. When disabled, symbol data is sent without the check
character.
Note: With Check Character Output Status and an External or Serial
trigger option enabled, an invalid check character calculation will cause a
No-Read message to be transmitted at the end of the read cycle.

characters that exceed three times (3x) the narrow element width.
