BC412

Check Digit Output (BC412)

Usage:

It is widely used in the semi-conductor manufacturing and is particularly

useful where speed, accuracy, and ease of printing are required.

Definition:

BC412 (Binary Code 412), a proprietary IBM symbology since 1988, is an

alphanumeric symbol with a set of 35 characters, each encoded by a set of

4 bars in 12 module positions. All bars have a single width and it is the

presence or absence of bars in each of the 12 module positions that makes

it a binary code (hence the prefix “BC”).

The symbology is bi-directional and self-clocking with a start and stop character.

Serial Cmd:

<K481,status,check digit output,fixed symbol length status,fixed symbol

length>

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Usage: Check digit Output, added to the symbol, provides additional 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 and an External or Serial trigger option

enabled, an invalid check digit calculation will cause a noread message to

be transmitted at the end of the read cycle.
