N O TE	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 the two matrices, they are electrically separate (example C8).
