Making a Connection
You can control the channels using the niSwitch Connect Channels VI or the niSwitch_Connect function.
For example, to close the relay of channel 1, call niSwitch_Connect(vi, "ch1", "com"). To open the relay of channel 1, call niSwitch_Disconnect(vi, "ch1", "com").
When scanning the NI PXI-2575, a typical scan list entry could be ch1->com;. This entry closes the relay between CH1 and COM.
