NI SCXI-1333 Installation Instructions
5. Expand the Number of Rows
The SCXI-1333 offers convenient methods for expanding the number
of rows of a matrix using two or more SCXI-1333 terminal blocks.
Caution
When using matrix expansion plugs, only connect terminal blocks of the same
type. Connecting different types of terminal blocks can damage the module or the
equipment connected to the module. For example, you can connect two or more
SCXI-1333 terminal blocks; however, do
not
connect the SCXI-1333 with any other
type of terminal block.
Figure 4 shows how to use a matrix expansion plug with SCXI terminal
blocks to expand the number of rows of a 4
×
32 matrix, as an example.
The matrix expansion plug connects columns to expand the number
of rows. To expand the number of rows of a matrix, connect a matrix
expansion plug to the top or bottom column connectors of the two terminal
blocks.
