13.1.5. GPIO TRIGGER
GPIO Trigger is a hardware trigger source accepting triggers from one of the General Purpose (GP)
Inputs of the device. Please refer to the Install Guide for details of the electric connection.
• Sample Rate, Required samples: The voltage across the GP Input's signal and ground pins is
sampled with the sample rate given. With mechanical switches it often takes a while for the
voltage level to settle. During this interval both high and low samples will be recorded. The
device will consider the input as settled when the number of samples that agree (last n
samples are low/high) exceeds the value given in Required samples.
• Logic active level: The voltage level that corresponds to the logic active level. Please note that
the trigger will not be asserted until one rising or falling edge is registered, regardless of the
value of this setting.
• GP Input: shows the current state of the input.
• GP Output: Is used to toggle the state of the General Purpose Output pin.
