niSwitch Route Trigger Input VI
- Updated2025-10-06
- 3 minute(s) read
Routes the input trigger from the front or rear connector to a trigger bus line (TTLx). To disconnect the route, call this VI again and select None for the trigger input bus line parameter.
This VI should be used when scanning a module in a different NI-SWITCH session that is not directly cabled to the trigger source ( multimodule scanning operations).
If this VI is used to route a trigger to a TTL line, specify the TTL line as the trigger input in the niSwitch Configure Scan Trigger VI.
