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 Figure 2-4 on page 2-6 for an example of a dot peen symbol). The DS3407-DP (DPM) digital
reader scans these types of symbols.
To configure the DS3407-DP digital scanner for DPM reading:
1. The DS3407-DP digital scanner can not read certain bar codes in near field. To ensure the digital scanner can
read all bar codes, scan Far Focus on page 5-5.
2. If you disabled DPM scanning in the DS3407-DP digital scanner, scan Enable DPM Scanning below.
3. Before scanning a DPM bar code, ensure you enabled Data Matrix on page 10-72.
NOTE When the DS3407-DP digital scanner is DPM enabled, the digital scanner reads all symbols including
DPM, 1D, PDF417, etc. If you do not require DPM reading, scan Disable DPM Scanning to ensure
optimum scanner performance.
If you enable DPM Scanning, disable Picklist Mode on page 4-10 when scanning a DPM bar code.
Picklist performance is not guaranteed for DPM bar codes.
Also, if you enable DPM Scanning, the scanner behaves as if the Data Matrix Inverse Autodetect setting
is selected. When you disable DPM Scanning, the previous (user-selected) Data Matrix Inverse setting
remains in effect. SeeData Matrix Inverse on page 10-73.
