NI PXI-2532 2-Wire 16×16 Matrix Topology
The NI TB-2645 terminal block creates a 2-wire 16×16 matrix topology with the NI PXI-2532. The following figure represents the NI PXI-2532 in the 2-wire 16×16 matrix topology.
Making a Connection
Both the scanning command, r6->c1;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters r6 and c1, result in the following connections:
signal connected to R6+ is routed to C1+
signal connected to R6– is routed to C1–
Terminal Block Connections
The NI TB-2645 terminal block connects the banks of the NI PXI-2532 to create the 2-wire 16×16 matrix topology. The following figure illustrates how the native banks on the NI PXI-2532 connect using the NI TB-2645 to create the 2-wire 16×16 matrix topology.
