Remote Trigger Port

GPIO
The main menu contains the Triggers/Alarms option from where the GPIO can be configured.
Outputs
The RBRX1 has four opto-coupled outputs, which can be set to provide status outputs when a parameter
exceeds a user defined threshold for a longer than a user defined hold time. The outputs can be configured to
be active high or low.
Each output is internally connected to a trigger input to facilitate automatic failover.
Trigger Inputs
The RBRX1 has four opto-coupled inputs which allow external signals to change the MPX source or the current
preset. The inputs are activated by pulling the pin low. If more than one trigger is active at the same time and
configured to produce conflicting behaviour, the lower trigger number gets priority (external triggers are higher
priority than internal triggers).
