Mounting
Ä
Observe the mounting instructions (see chapter 4.1 "Selecting a mounting location").
Ä
Fasten the bar code reader on the mounting threads (see chapter 3.3 "Device construction"):
• M3 mounting threads on the rear of the device
• M2.5 mounting threads on the device side
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).
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 re-
spective 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 approx. 15°.
NOTICE
Avoid direct reflection of the laser beam!
The beam exits the bar code reader perpendicular to the reading window.
Ä
The bar code label must be rotated by > 10 ° to avoid a reflection of the laser beam in the
case of glossy labels.
