Ä Fasten the bar code reader on the M4 mounting threads on one side of the device (see chapter 3.3
"Device construction").
4.1 Selecting a mounting location
NOTICE
The size of the bar code module influences the maximum reading distance and the width of the
reading field.
Ä When selecting a mounting location and/or the bar code label, take into account the different
reading characteristics of the bar code reader with various bar code modules.
NOTICE
Observe when choosing the mounting location!
Ä Maintain the permissible environmental conditions (humidity, temperature).
Ä Avoid possible soiling of the reading window due to liquids, abrasion by boxes, or packaging
material residues.
Ä Ensure that there is the lowest possible chance of damage to the bar code reader by me-
chanical collision or jammed parts.
Ä Avoid possible ambient light influence (no direct sunlight).
Mounting
In order to select the right mounting location, several factors must be considered:
• Size, orientation, and position tolerance of the bar codes on the objects to be scanned.
• The reading field of the bar code reader in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading field with the respective module width (see chapter 12.2 "Reading fields").
• alignment of the bar code reader for avoiding reflections.
• distance between bar code reader and host system with respect to the interface.
The best read results are obtained if the following prerequisites are fulfilled:
• The reading distance lies in the middle area of the reading field.
• There is no direct sunlight and ambient light influences are avoided
• The bar code labels are of good print quality and have good contrast ratios.
• You are not using glossy labels.
• The bar code is moved past the reading window with an angle of rotation of 10° to 15°.
