DPM Scanning
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 DS3478-DP (DPM) digital
reader scans these types of symbols.
To program the DS3478-DP digital scanner for DPM reading:
1.
The DS3478-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 you disabled DPM scanning in the DS3478-DP digital scanner, scan
Enable DPM Scanning
.
3.
Before scanning a DPM bar code, ensure that
Data Matrix on page 13-71
is enabled.
NOTE
When the DS3478-DP digital scanner is DPM enabled, the digital scanner reads all symbols including
DPM, 1D, PDF417, etc. If you don’t need DPM reading, scan
Disable DPM Scanning
to ensure optimum
scanner performance.
If you enable
DPM Scanning
, disable
Picklist Mode on page 4-7
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 you enabled the
Data Matrix Inverse
Autodetect
setting. When you disable DPM Scanning, the previous (user-selected)
Data Matrix Inverse
setting remains in effect. See
Data Matrix Inverse on page 13-71
.
