NI PXI-2532 Matrix Expansion
You can expand the matrices of the NI PXI-2532 by increasing the number of columns in the matrix.
To expand the number of columns, use the terminal block ribbon cable headers to connect the rows on adjacent terminal blocks. The following table lists the available terminal blocks and matrix configurations.
| Terminal Block | Configuration (Row x Column) |
|---|---|
| NI TB-2640 | 4×128 |
| NI TB-2641 | 8×64 |
| NI TB-2642 | 16×32 |
| NI TB-2643 | Dual 4×64 |
| NI TB-2643 | 2-wire 4×64 |
| NI TB-2644 | Dual 8×32 |

Column Expansion on the NI PXI-2532
The NI TB-2640/2641/2642/2643/2644 terminal blocks provide ribbon cable headers to connect the rows on two adjacent terminal blocks and expand the number of columns of a matrix.
The column expansion procedure is the same for all of the terminal block modules. The following figure illustrates how to use ribbon cables to connect rows on multiple NI TB-2640 modules and expand the number of columns.
Complete the following steps to expand the number of columns of a matrix.
- Connect one end of the ribbon cable to a row ribbon cable header on one of the NI TB-2640 terminal blocks.
- Connect the other end of the ribbon cable to a row ribbon cable header on another NI TB-2640 terminal block.
