The following figure represents the NI PXI/PXIe-2575 (NI 2575) in the 1-wire 196×1 multiplexer topology.

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 2575, a typical scan list entry could be ch1->com;. This entry closes the relay between CH1 and COM.
