are moved, replace both jumpers to the lower
positions.
Two of the jumpers on the breakout board (top
board) are used to internally connect the
OUTPUTS of the CLCI2000 to the Motor
ON/OFF input of the drivers.  These jumpers
are set to connect the indexer Outputs to the
driver ON/OFF inputs when shipped from the
factory.  The other two jumpers are for use
with future driver boards.  See Table 2 and
Figure 1  for details on  jumpers.
