Appendix D — EA30 Imager
ED40 Decode Board Integration Guide 131
Motion Tolerance
One of the important features of the EA30 imager is it’s high level of motion
tolerance. Maximum motion tolerance for the EA30 is 500 inches per second.
In this section we provide 3 basic setup modes for motion tolerance:
• Standard Motion Tolerance (default settings)
• Improved Motion Tolerance
• Maximum Motion Tolerance
Each setup mode uses 3 different setup parameters. The settings provided were
tested on code EAN, in typical office environment (250 lux) with the goal of
obtaining a high motion tolerance rate with an acceptable decode rate (not 100%).
Keep in mind that the settings may vary depending on your application and the
environment.
Note: Setting up the imager for maximum motion tolerance will modify some
imager performances such as reading distances and peak current. This section
gives an idea of how different performances are affected.

Imager Performance
Standard
(default) Illumination level = 60
Lighting goal = 128 190 in/sec 500 mA No degradation in imager performances.
Improved Illumination level = 70
Lighting goal = 70 350 in/sec 700 mA High contrast bar codes required.
Reading distances are decreased around 10%
compared to the standard mode.
Maximum Illumination level = 100
Lighting goal = 46 500 in/sec 1200 mA High contrast bar codes with a minimum
resolution of 0.125 mm/5 mils required.
Reading distances are decreased around 30%
compared to the standard mode.
Reading distances on DataMatrix 0.18 mm/7
mils can decrease up to 60%.
