Figure 2-23. 8 × 8 Matrix Schematic
To make a larger matrix, such as a 8 × 16 matrix, you must make both
column and row expansions. Follow these instructions to build a larger
matrix:
1. Expand the columns to the target number, 16 in this case, by
connecting the rows of the appropriate number of SCXI-1332s, two in
this case, using matrix expansion cables. This results in a 4 × 16 matrix
block.
