Mounting the Scanner

Integrating the Scanner Behind a Window

It is not recommended to place any type of additional window between the scanner and the bar
code to be read. The addition of a host enclosure window will significantly degrade scanner
performance. This is due to the additional optical reflective surfaces that will cause interfer-
ence with the imaging technology.
CAUTION
It is recommended to conduct scan performance testing with any additional window to
determine if the performance level is acceptable for the application.
• Window material should be transparent with 92% transmission to wavelength
• Flat window only.
• The window should be as thin as possible (thickness less than 2mm).
• The window should be as close to the LED baffle or original window as possible to
Performance degradation may include:
• The scan module will not read very low contrast labels.
• Red LEDs flash or red LEDs are always on. In this case, the scanner module's near
• The scan module will not be able to wake up especially in low ambient light (typi­

ESD Protection

The host enclosure design must provide adequate ESD protection for the scanner. Ide­
ally, static discharge should not be allowed to discharge to the scanner. The preferred
method to prevent static discharge is to provide a long discharge path to all circuits.
The scanner is intended to be mounted inside a host enclosure. Only the front surface
should be exposed in order to read bar codes. This is to protect the rear interface con­
nector area which can be susceptible to static discharge. Interface cables should also not
be powered up when inserted into the scanner. It is also recommended that any metal
mounting surfaces for the scanner must be electrically grounded.
Static discharge (ESD) testing is recommended for the entire system integration to
ensure proper ESD protection.
Proper ESD protection should be used at the time of installation and servicing of the
scanner or the host equipment.
