Not recommended for new designs. Consider the NI PXI-2532B.

The NI PXI-2532 is a 512-crosspoint, high-speed matrix switch module. With the largest matrix size available in a 3U PXI slot, the PXI-2532 offers ultrahigh-density switch configurations in PXI. You can use it to create up to a 4x2176 or 8x1088 1-wire matrix in a single PXI chassis and even larger configurations with multichassis solutions, making this switch module ideal for high-channel-count automated test configurations. Featuring compact reed relays with switching speeds up to 2,000 cycles/s and the ability to synchronize with instruments, the PXI-2532 provides maximum throughput in a test system for signals up to 100 VDC/100 Vp or 0.5 A.

Connecting Signals to the PXI-2532
You can choose from several accessory options for the PXI-2532. To make any signal connection to this switch module, you need to use one of the TB-264x front-mounting terminal blocks, which provide signal connections through ribbon cable headers. An optional set of four “column” cables and one “row” cable is available to make these connections. If you prefer screw terminal connections, you can use the SCB-264X screw terminal breakout accessory to connect to the other end of the ribbon cables coming out of an individual TB-264x front-mounting terminal block.

Column Expansion Through Row Connections
If you need a matrix size larger than one of the standard PXI-2532 configurations, you can use the NI R1616 column expansion cable to interconnect the rows of two PXI-2532 modules via a TB-264x terminal block. For instance, you can create a 4x256 1-wire matrix with two PXI-2532 modules, two TB-2640 terminal blocks, and one R1616 column expansion cable interconnected between the TB-2640 devices.

NI Switch Executive Switch Management Software
NI Switch Executive is an intelligent switch management and routing application. With NI Switch Executive, you gain increased development productivity by interactively configuring and naming switch modules, external connections, and signal routes. You also increase test code reuse and system performance with switch programming using NI TestStand, LabVIEW, and Measurement Studio. Ultimately, NI Switch Executive simplifies switch system configuration and increases test performance, lowering your cost to test.
