4.1.7 Trigger Input/ Output
Trigger input supports de-bounce filter function to help filter out environmental noise that can
mix with normal encoder signals and affect the accuracy of the pulse count. The de-bounce
filter defines the interval width for high/low signals. Signals with interval width less than the
defined value will be filtered out.
Below is a diagram illustrating the case of filter timer set with a duration time of 2 milliseconds:
Trigger Output CH 0~4 provides the following parameters to configure:
 Trigger source
The user can select any of the following items as a triggering condition that prompts the
MVS900 to generate a trigger output: Trigger Input CH 0~3, Encoder 0_Linear 0,
Encoder 0_Linear 1, Encoder 0_FIFO, Encoder 1_Linear 0, Encoder 1_Linear 1, Encoder
1_FIFO
Note: One trigger source can be set to activate multiple trigger outputs.
 Delay time function
The user can set the delay time that the system waits before it sends a trigger output.
 Duration time
The user can adjust pulse width for the output signal.
