NI PXI-2530 1-Wire Octal 16×1 Multiplexer Topology

Use the NI TB-2630 terminal block with the NI PXI-2530 as a 1-wire octal 16×1 multiplexer. In this topology, channel terminals CH0 through CH15 route to COM0. All other banks follow a similar routing scheme.

The following figure represents the NI PXI-2530 in the 1-wire octal 16×1 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
