– Example Large Synchronized Network Reading Station
Here are a few helpful hints which can improve station performance and reduce installation
time:
1. Scanner distribution should alternate between odd and even branches so that the
station guarantees 50% reading on all sides. See also Figure 75.
2. For OEK Encoders set the parameter Operating Mode>Encoder Step = 252.

3. For Top Front and Top Back scanners ( C and D in Figure 76), set the parameter
Reading Parameters>Reading Condition = Skew 45°.
4. For applications having regular shaped packs the default settings are sufficient, but
for Airport applications, irregular shaped packs can cause PS signal glitches resulting
in false "packs too short" or "packs too close" errors.
To correct this, set the following Operating Modes parameters:
Minimum Distance
Between Packs = 200 mm, Minimum Pack Length = 200 mm, Window Dimension = 200 mm
