5 Matrix Switch Modules
NOTE
On the 34931T terminal block, only two sets of screw terminals are
for use with the 34931A module. See the following drawing.
When using the 34931T terminal block, be sure to
wire your connections to the two sets of screw terminals
closest to the 50-pin D-sub connectors.
Although columns are numbered the same on
Matrix 1 and Matrix 2, they are electrically separate
from one another (e.g., Col C8).
