NI SCXI-1332 Installation Instructions

5. Expand the Number of Rows

The SCXI-1332 offers convenient methods for expanding the number of 
rows of a matrix using two or more SCXI-1332 terminal blocks.

Figure 4 shows how to use two matrix expansion cables with SCXI-1332 
terminal blocks to expand the number of rows of a 4

×

8 matrix. The matrix 

expansion cable connects columns to expand the number of rows. To 
expand the number of rows of a matrix, complete the following steps:

1.

Connect one end of a matrix expansion cable to a column connector in 
one of the terminal blocks.

2.

Connect one end of a second matrix expansion cable to another column 
connector in the same terminal block.

3.

Connect the other end of each matrix expansion cable to two column 
connectors in another terminal block.

Figure 4.  

Expanding the Number of Rows with Matrix Expansion Cables

The SCXI-1332 configures the SCXI-1127/1128 as a 4

×

8 matrix. 

Connecting the SCXI-1332 terminal blocks as described above creates 
an 8

×

8 matrix.
