10.8 Modulation frequency mode
The "Modulation frequency mode" enables the use of several devices in the same field of view .
Each device uses several modulation frequencies to increase the range . If more than one device is
needed for an application, interferences may occur . The devices interfere with each other by using the
same modulation frequency .
With the "Modulation frequency mode", you can assign different modulation frequencies to the devices .
The modulation frequency is set in the "Modulation frequency mode":
You can choose among the following:
●
three frequency sets with fixed default modulation frequencies
●
one frequency set with a random choice of modulation frequencies
Test the ideal filter setting under difficult conditions:
●
strong sunlight
●
wet surfaces
10.8.1 Fixed modulation frequencies
The fixed frequency sets consist of three modulation frequencies which cannot be changed .

The fixed frequency sets are suited for applications with the following properties:
●
fixed device position (no vehicles)
●
maximum of three devices in one field of view
The noise level of the fixed modulation frequencies is lower than the one of the random modulation
frequencies (→ „10.8.2 Random modulation frequencies“).
►
Use the fixed modulation frequencies by preference .
