Making a Connection

Call the niSwitch Connect Channels VI or the niSwitch_Connect function to connect channels in this topology. If applicable, you must call the niSwitch Disconnect Channels VI or the niSwitch_Disconnect function to disconnect an existing connection before you call the niSwitch Connect Channels VI or the niSwitch_Connect function.

The following sequence of tasks illustrates the VI/function calls necessary to make consecutive connections—one between CH 1A and COM 1 and the other between CH 2B and COM 2:

  1. Call the niSwitch Connect Channels VI or the niSwitch_Connect function with parameters ch1A and com1.
  2. Call the niSwitch Disconnect Channels VI or the niSwitch_Disconnect function with parameters ch1A and com1.
  3. Call the niSwitch Connect Channels VI or the niSwitch_Connect function with parameters ch2B and com2.

When scanning the module, a typical scan list entry might be ch1A->com1;. This entry routes the signal connected to CH 1A to COM 1.
