NI SCXI-1130 1-Wire Sixteen 16×1 Multiplexer Topology

Use the NI SCXI-1377 terminal block with the NI SCXI-1130 as sixteen independent 1-wire 16×1 multiplexers. In this topology, channel terminals CH 00 through CH 15 route to OUT0, which is addressed as com0 in software. The other fifteen banks follow a similar routing scheme.

The following figure represents the NI SCXI-1130 in the 1-wire sixteen 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:

CH 02 connected to OUT0
