NI PXI-2584 1-Wire 12×1 Multiplexer Topology

Install an external jumper wire between the COM0 and COM1 pins to use the NI PXI-2584 as a 1-wire 12×1 multiplexer. The following figure represents the NI PXI-2584 1-wire 12×1 multiplexer topology.

Making a Connection

Both the scanning command, ch2->com0;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters ch2 and com0, result in the following connection:

Signal connected to CH2 is routed to COM0.

Both the scanning command, ch7->com0;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters ch7 and com0, result in the following connection:

Signal connected to CH7 is routed to COM1.
