Application examples of the algorithms
This section describes some of the algorithms of the menu item "Settings - Read points" of
the WBM based on application examples.
Minimizing radiated power
Description
In this example, the read points are mounted very close to each other. This makes it very
likely that these read points will influence each other if the radiated power is too high. There
is always roughly the same number of transponders in the antenna field (1-3 transponders).
The aim is to reliably identify the transponders without the read points influencing each other.
● Inventory Power Ramp
● Read/Write Power Ramp
The read points are mounted, equipped and aligned and during reading there are
transponders in the antenna field.
Note that this example is only of practical use when the reader searches for transponders for
a defined period. This is controlled by a light barrier which for example triggers a trigger
"IO_LEVEL" or "IO_EDGE" or by parameter assignment of the period of an inventory
command.
If there are no transponders in the antenna field during the reading, the read point will
automatically always use the maximum possible set dB value.
