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 DS3408-DP (DPM) digital
reader scans these types of symbols.
To ensure the DS3408-DP digital scanner is programmed for DPM reading:
1.
The DS3408-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 5-3 .
2.
If DPM scanning was disabled in the DS3408-DP digital scanner, scan Enable DPM Scanning (below).
3.
Before scanning a DPM bar code, ensure that DataMatrix on page 13-68 is enabled.
NOTE When the DS3408-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 Mode on page 4-9 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 DataMatrix Inverse Autodetect setting
is selected. When you disable DPM Scanning, the previous (user-selected) DataMatrix Inverse setting
remains in effect. See DataMatrix Inverse on page 13-69 .
