Matrix Configuration

Wide matrix expansion (10 

×

 6 matrix) 

A   wide   ten-row   by   six-column  matrix  is  shown  in
Figure 2-10.  For  this  configuration, the  six  columns  of the
two  matrices  must  be physically  hard-wired  together.  Also

note that the backplane jumpers on one of the cards must be
removed in order to isolate the rows of the two cards from
each other.
