Connect an ex5 V power supply to the UMI-7764 Power Input Terminal Block. This
connection is required to power the encoder circuitry that converts differential encoder
signals to single-ended signals for the motion controller, as well as to power the UMI-7764
Inhibit Output signals.
Caution
Do not plug in or turn on any power to the system until after all hardware
connections are complete.
