Current Sensing Jumpers
A third 0.100” header P2 is provided for ground reference. Both P2 pins are
connected to the isolated ground.
For accurate current measurements, all JP1 headers shall be installed (see section:
Mote Signal Disconnection).
Note: In applications where a high current is required, jumper P4 shall be installed;
this shunts the sense resistor R55 and eliminates the associated voltage drop.
Jumper Settings
The Interface Card features the jumper loading options depicted below.
