Set the jumper for any position and use the solder pads on the DB25
connector to bring out connections for channels 4 and 5. The other
channels already have selectable gains.
To support all 11 channels on the SDAxx modules connect 3
SDAIBBs to the I/O port of the SDAxx as shown in Figure 2 on page 4 and
set one board to JP9, one to JP10, and the last to JP11. This will provide
11 independent buffered inputs.
