- export_signal(signal_id, output_terminal)[source]
Routes a control signal to the terminal you specify. The output terminal can reside on the device that generates the control signal or on a different device. You can use this function to share clocks and triggers among multiple tasks and devices. The routes this function creates are task-based routes.
- Parameters
signal_id (nidaqmx.constants.Signal) – Is the name of the trigger, clock, or event to export.
output_terminal (str) – Is the destination of the exported signal. A DAQmx terminal constant lists all terminals on installed devices. You can also specify a string containing a comma-delimited list of terminal names.
