Changes to Chapter 3. F3-04ADS 4-Channel Isolated Analog Input
Page 3-3. Setting the Module Jumpers; Jumper Locations
The PC board was redesigned and the locations of jumpers J10, J11, J12, and J13 changed. The jumpers were rotated 90
degrees and are closer to the back of the module than the original layout. The functionality of the jumpers did not change. The
orientaton of the 5 pairs of pins for each channel is the same.
The photo on the right shows the new design, while the one on the left shows the original PC board. The photo on the left matches the drawing shown on page 3-3.
