Jumper Shunt Position Jumper Description
W1 Pins 1-2 Controls CHA1(+) input source selection
W2 Pins 1-2 Controls CHA1(–) input source selection
W3 Pins 2-3 Controls reference source (default is internal)
W4 OPEN 3X2 Jumper to control A0, A1, A2
W5 Pins 1-2 Controls BVdd Selection, should remain on pins 1-2 for the ADS7864
W6 Closed Controls application of A0, A1 and A2 signals as well as the chip select input. Used in conjunction
with W4.
W7 Closed Controls BYTE input, opening W7 forces BYTE high via R23
W8 Pins 2-3 Controls application of conversion clock source via J5 or J7
W9 NA W9 pins 2-3 are wired short on the PWB
W10 TIMER 3 × 3 Jumper to control HOLDx signals – timer or GPIO options available
