The NI TB-2645 terminal block creates a 1-wire dual 16×16 matrix topology with the NI PXI/PXIe-2532 (NI 2532). The NI TB-2645B terminal block creates a 1-wire dual 16×16 matrix topology with the NI PXI/PXIe-2532B (NI 2532B).The following figure represents the NI 2532/2532B in the 1-wire dual 16×16 matrix topology.
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. |
The NI TB-2645 terminal block connects the banks of the NI 2532 to create the 1-wire dual 16×16 matrix topology. The NI TB-2645B terminal block connects the banks of the NI 2532B to create the 1-wire dual 16×16 matrix topology. The following figure illustrates how the native banks on the NI 2532/2532B connect using the NI TB-2645/2645B to create the 1-wire dual 16×16 matrix topology.
The following table lists the pin assignments for the NI TB-2645/2645B column ribbon cable headers.

Note The column connection board J2 connector on the NI TB-2645 is not used in this configuration. |
The NI TB-2645/2645B requires two row ribbon cables for row connections. The NI TB-2645 provides one pair of ribbon cable headers to connect your application. The NI TB-2645B provides two pairs of ribbon cable headers. Use one cable header pair to connect to your application and the other for column expansion.
The following tables list the pin assignments for row connection.
The following table refers to the J2 connector on the NI TB-2645 Module Interface Board and the J4 and J5 connectors on the NI TB-2645B.
