DIP switch on the module (component side, middle)
You can determine slow and fast input signals with high measurement rate
without switching, by connecting 1 counter input with 2 counters. For this you
have to change the DIP switch positions on the module:
– Switch counter 3 (additionally to counter 1) to counter input 1:
Push the switches of the upper double DIP switches upwards.
– Switch counter 4 (additionally to counter 2) to counter input 2:
Push the switches of the lower double-DIP switches upwards.

The figure below illustrates the DIP switch positions and the resulting
input-counter-connections.
Program one of the two counters with CLK and DIR signal inputs (up/down
counter), the other with PWM-input (PWM analysis). In a corresponding
ADba-
sic process you can now determine the frequency or period duration of the sig-
nal in a wide frequency range.
