Ground Reference (Connected to ACC-72EX and UMAC’s Digital
Ground)
Note:
The USB connection is not a galvanically isolated connection. The ground of the
PC will be connected to the ground of the UMAC system through the USB
connection, which can damage components on the PC and/or ACC-72EX. Make
sure that there is no potential difference between the grounds on both ends.
