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.
