3.2 Digital Output
The AIIS-1882 has digital output function. The following sections describe the digital
output update/generation mechanism. For detailed specification of the functions.
refer to Appendix A.
3.2.1 Static Digital Output Update
With static digital output update, the digital output state is updated only when the soft-
ware sends a “write static digital output sample” command. The digital output state
remains unchanged at other times. This is shown in Figure 3.7.

3.3 PWM Lighting Output Control
The lighting control leverages a Pulse Width Modulation (PWM) mechanism. A pulse
waveform with specified high period (tHIGH) and low period (tLOW) is output at
counter output terminal as shown in Figure 3.8.
Figure 3.8 Pulse width modulation output
The lighting intensity is controlled by the PWM high period. For example, in the same
PWM cycle period of 100 ms, setting the high period to 100 ms drives the lighting to
maximum intensity, while setting it to 0 ms turns the lighting off. Figure 3.9 describes
the relationship between duty cycle and lighting intensity percentage. With a duty
cycle of 25%, the ON period is 25% of the PWM cycle, which results in 25% lighting
intensity. The same applies when the duty cycle is set to 50% or 75%.
