Making a Connection

You can control the channels using the niSwitch Connect Channels VI or the niSwitch_Connect function.

For example, to connect the NO terminal of channel 1 to the COM terminal of channel 1, call niSwitch_Connect (vi, "no1", "com1"). If you now want to connect NC1 to COM1, first disconnect the existing connection. The sequence of calls for this task is as follows: 

niSwitch_Disconnect(vi, "no1", "com1")
niSwitch_Connect(vi, "nc1", "com1")
Note niSwitch_Disconnect(vi, "no1", "com1") does not operate the relay until the niSwitch_Connect(vi, "nc1", "com1") is executed.
Note For an initial connection, you do not need to disconnect the default channel (ncx) from COM after the module has been reset or a call to the niSwitch Disconnect All Channels VI or the niSwitch_DisconnectAll function has been made.

When scanning the module, a typical scan list entry could be nc1->com1;. This entry routes the signal connected to NC1 to COM1.
