DataMan 290 DataMan 390 Data Matrix Code Decode Time

The out of the box experience in terms of decoding speed compared to older code readers of this class may be disappointing using factory default settings.

Question

Why is the decode time on my new DataMan 290 or DataMan 390 significantly higher than when reading the same code with a DataMan 280 or DataMan 150/260 reader?

Answer

The DataMan 290 and DataMan 390 readers include an AI-supported finder algorithm that runs on a dedicated Neural Processing Unit (NPU). This AI-based finder enhances code detection in challenging applications but also adds additional processing overhead to each decode cycle.

As a result, decode times may be higher compared to older DataMan readers that rely exclusively on rule-based decoding algorithms.

Many applications do not require AI-assisted finding and will perform well using the standard algorithms alone.

How to Reduce Decode Time

If AI-assisted finding is not required for your application, it can be disabled manually:

  1. Open DataMan Setup Tool
  2. Go to Optimize Image → Application Step
  3. Open the Advanced tab
  4. Disable the AI Enhancer

Disabling this feature reduces processing load and can significantly improve decode time.

Summary

  • DataMan 290 / DataMan 390 use AI-based finders running on an NPU.
  • AI processing increases decode time in some applications.
  • Standard rule-based decoding is sufficient for many use cases.
  • Disabling the AI Enhancer can improve performance.
