This link must be in position "A" if a bipolar AIN signal is being applied to the bipolar Vin socket, SK3.
This link must be in position "B" if a unipolar AIN signal is being applied to the unipolar Vin socket, SK1.
This link is used to connect in the impedence matching resistor, R5, for unipolar Vin.
This link is used to connect in the impedence matching resistor, R7, for bipolar Vin.

SET-UP CONDITIONS
Care should be taken before applying power and signals to the evaluation board to ensure that all link positions are as per the
required operating mode. Table I shows the position in which all the links are set when the evaluation board is sent out. All
links are set for use with the EVAL-CONTROL BRD2.
Table I. Initial Link and Switch Positions
Link No.
