  • Page 40 (3657.60 meters) Grounding Recommendation It is recommended that you connect the tabs on the chassis of the Digi Connect ME / Wi- ME, and the ground pins directly to the logic ground plane. It is also recommended that you connect the Digi Connect ME / Wi-ME to the metal chassis of your enclosure. The idea is to provide the shortest path or a path away from circuitry for ESD to travel to ground.

  • Page 41: Power Management (Connect Me-9210 Only)

    Based on the application needs, wake-up triggers can be set up programmatically to activate the processor back to wherever it left off. In this mode, a drastic power reduction is realized by reducing the power consumption of the Digi NS9210 processor and the on- module PHY.
