DPM Mode
Parameter # 1438 (SSI # F8h 05h 9Eh)
Unlike barcodes typically printed on labels, a direct part mark (DPM) is a symbol that is marked directly on an
item's surface for permanent identification, using methods such as laser etching, dot peening, or direct-printing.
Select one of the following DPM modes based on the type of barcode being scanned. There are two DPM modes
which are recommended for different sets of barcode characteristics. The combinations of these characteristics
vary and it is recommended that all modes are tested on the target barcode to determine the best mode for the
application.
• Disable DPM Mode - No special processing occurs.
• DPM Mode 1 - Optimizes decoding performance on smaller DPM barcodes, typically found on electronics
and medical instruments, especially on smooth surfaces. These barcodes tend to be laser etched or
direct-printed.
• DPM Mode 2 - Optimizes decoding performance on larger DPM barcodes, typically found on industrial parts,
especially on rough, grainy, or visibly machined surfaces. These barcodes tend to be dot-peened or laser
etched.
NOTE This parameter applies to the DS36X8-DP only.
NOTE If you enable DPM Mode, the decoder behaves as if the Data Matrix Inverse Autodetect setting is
selected.
