INSTALLATION

The reading distance of the scanner with the OM2000N is shifted by 10 mm towards the

scanner because of the internal optical path between the scanner and the OM2000N output

window. The reading performance also decreases in typical conditions by about 10% due to

the optical signal passing through the output window of the OM2000N and the reflection on

the mirror surface. The combination of these effects produces the reading diagram

represented below:

The reading distance also depends on the amplitude of aperture used. In particular, wider

apertures require the scanner to be closer to the code in order to read at the extreme edges

of the sweep (see Figure 34 below).

The OM2000N is configurable exclusively through the Genius™ utility
