The analog input channels can be jumper-configured to accept voltages in any one
of three ranges. There are two bipolar ranges and one unipolar range.
Bipolar Ranges

Programmable Gain Selection
(J15 & J19; J14 & J18; J16 & J20)
The gain for each input channel is individually programmable over any one of three
possible gain ranges.
three pairs of jumpers (J15 & J19;
gains (within the selected range) are determined by the user and written to on-
board Gain RAM during an input initialization procedure (See Section 3.3.3).
Thereafter, any time an input is converted (analog-to-digital), it will automatically
apply the gain factor for which it was previously programmed.
gain ranges are:
Range 1:
Range 2:
Range 3:
