Making a Connection
The NI PXI-2529 combined with the NI TB-2634 or the NI TB-2636 creates a 4×32 matrix. In this topology, you can connect any row to any column. When connecting signals to r1, you would connect them to R1+ and R1– in the terminal block. When connecting signals to c0, you would connect them to C0+ and C0– in the terminal block.
You can connect the channels of the NI PXI-2529 using the niSwitch Connect Channels VI or the niSwitch_Connect function. For example, to connect row 1 to column 1, call the niSwitch Connect Channels VI or the niSwitch_Connect function with the channel 1 parameter set to r1 and the channel 2 parameter set to c1.
When scanning the NI PXI-2529 in 4×32 matrix topology, a typical scan list entry could be r1->c20;. This entry routes the signal connected to row 1 to column 20.
