×××× 8 Matrix Configuration

You can configure the SCXI-1127/1128, with the SCXI-1332 as an 4 

× 8, 

four rows by eight columns, matrix. The SCXI-1332 terminal block has 12 
pairs of screw terminals, eight pairs for accessing eight columns (C0...C7) 
and four pairs for accessing four rows (R0...R3) of the 4 

× 8 matrix when 

installed in the front connector of the SCXI-1127/1128. In addition to the 
screw terminals, the SCXI-1332 has six connectors for matrix expansion. 
Four of the six connectors are for expanding the eight columns and the 
other two connectors are for row expansion. The SCXI-1332 is shown in 
Figure 2-19.
