Connects two channels by specifying an explicit path in the path list parameter. This VI is useful where path repeatability is important, such as in calibrated signal paths. If path repeatability is not necessary, use the niSwitch Connect Channels VI.

To obtain the exact path for a given connection, use the niSwitch Get Path VI.

path list is a string composed of comma-separated paths between channel 1 and channel 2. The first and last names in the path are the path endpoints. All other channels in the path are configuration channels.

Example of a valid path list string:

ch0->com0, com0->ab0.

In this example, com0 is a configuration channel.

Obtain the path list for a previously created path with the niSwitch Get Path VI.
