DPM Scanning

Parameter # F1h, 09h
Unlike bar codes that are typically printed on labels, a direct part mark (DPM) is a symbol that is marked directly on
an item's surface for permanent identification. These symbols are marked using methods such as laser etching
and dot peening (see
reader scans these types of symbols.
NOTE When the DS3407-DP digital scanner is DPM enabled, the digital scanner reads all symbols including
DPM, 1D, PDF417, etc. If DPM reading is not required, scan Disable DPM Scanning to ensure optimum
scanner performance.
If you enable DPM Scanning, disable
Picklist performance is not guaranteed for DPM bar codes.
Also, if you enable DPM Scanning, the scanner behaves as if the DataMatrix Inverse Autodetect setting
is selected. When you disable DPM Scanning, the previous (user-selected) DataMatrix Inverse setting
remains in effect.
To ensure the DS3407-DP digital scanner is programmed for DPM reading:
The DS3407-DP digital scanner can not read certain bar codes in near field. To ensure the digital scanner can
