I’m wondering what is the correct/recommended way to ground the Connect ME module. My original way is to connect the tabs on the chassis of the Digi to physical earth, and the ground pin of the module to the ground of power supply. But I saw a Grounding Recommendation on Module Specifications, and it says:
It is recommended that you connect the tabs on the chassis of the Digi Connect ME, and the ground pins directly to the logic ground plane. It is also recommended that you connect the Digi Connect ME to the metal chassis of your enclosure.
I’m confused now. Do anyone know what the Grounding Recommendation really means? Is my way correct? If not, does it affect the performance of Digi?
