Figure 3.9 Lighting output intensity with different PWM duty cycles

The lighting output could be set to 3 modes:

1.

Infinite lighting output

2.

Finite lighting output period

3.

Strobe (single PWM output)

The corresponded parameters to configure are

high period

,

low period

, and output

count. The high period and low period define the PWM high and low time span in a

period of PWM output respectively. The output count specifies the number of PWM

period that the output generates in each output cycle. The configuration interface in

Navigator is as shown below:
