NI PXI-2532 1-Wire Dual 16×16 Matrix Topology
The NI TB-2645 terminal block creates a 1-wire dual 16×16 matrix topology with the NI PXI-2532. The following figure represents the NI PXI-2532 in the 1-wire dual 16×16 matrix topology.
Making a Connection
For bank 0, both the scanning command, b0r1->b0c1;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters b0r1 and b0c1, result in the following connection:
signal connected to B0R1 is routed to B0C1
For bank 1, both the scanning command, b1r1->b1c1;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters b1r1 and b1c1, result in the following connection:
signal connected to B1R1 is routed to B1C1
 |
Note While you can, for example, connect B0R1 to B0C0, you cannot connect B0R1 directly to B1C1 in this topology. |
Terminal Block Connections
The NI TB-2645 terminal block connects the banks of the NI PXI-2532 to create the 1-wire dual 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 1-wire dual 16×16 matrix topology.
