Expanding the NI PXI-2530 Matrix Using the NI TB-2631

Use the NI TB-2631 and bare wire to expand the NI PXI-2530.

Getting Started

To expand the NI PXI-2530, you need the following items:

• Bare wire
• Two or more NI TB-2631 terminal blocks
• Two or more NI PXI-2530 switch modules

NI TB-2631 Terminal Reference

Refer to the following figure and complete either Expanding the NI PXI-2530 Columns or Expanding the NI PXI-2530 Rows to expand the NI PXI-2530.

Expanding the NI PXI-2530 Columns

Complete the following steps to expand the columns of an NI PXI-2530 using an NI TB-2631 terminal block.

1. Connect one end of the bare wire to a row screw terminal on one NI TB-2631.
2. Connect the other end of the bare wire to the corresponding row screw terminal on another NI TB-2631.
3. (Optional) To expand the columns on the NI PXI-2530 further, attach another bare wire to the row screw terminal you accessed in the previous step, and connect the other end of the bare wire to the corresponding row screw terminal on another NI TB-2631.
4. Repeat the previous steps for all rows.

Expanding the NI PXI-2530 Rows

Complete the following steps to expand the rows of an NI PXI-2530 using an NI TB-2631 terminal block.

1. Connect one end of the bare wire to a column screw terminal on one NI TB-2631.
2. Connect the other end of the bare wire to the corresponding column screw terminal on another NI TB-2631.
3. (Optional) To expand the rows on the NI PXI-2530 further, attach another bare wire to the column screw terminal you accessed in the previous step, and connect the other end of the bare wire to the corresponding column screw terminal on another NI TB-2631.
4. Repeat the previous steps for all columns.
