Module Jumpers
If a sensor or combination of sensors connected to an analog or
Serial Expansion Module draw more than 300 mA current total, then
a terminal link must be placed onto both jumpers located above the
network connector, inside the module as shown below. This bypasses
the isolated power supply within the module.
 Note:
Do not bypass the isolated power supply unless necessary
