Selecting the installation site
When selecting the installation site take the distance between the CLP 100 and the host as
well as the distance between the CLP 100 and the bar code into consideration. The angle
between the scan line and bar code is selected, so that a good reading is possible. The
optimal setting of the angle is described further below.
The CLP 100 is fastened by means of two threaded holes (M
3) to the top or bottom of the
device (
refer to Figure 4-1
). The complete housing dimensions are shown in
Section 9.2,
Page 32
Distance between the CLP 100 and the host
The maximum distance between the CLP 100 and the host when extension cables are used
amounts to 12 m (host interface RS-232).
Distance between the CLP 100 and the bar code
The distance a between the reading window of the CLP 100 and the bar code must amount
to 20 to 70 mm depending on the width of the bar code (
refer to Figure 4-2
Section 10.3,
Page 38
shows the width of the reading area of the CLP 100 in relation to the reading
distance for various resolutions (module widths).
