The ThinkCentre Nano IoT IOBOX connects to Nano IoT PCs via a Type-C connection, providing extra vertical IO offerings such as Power over Ethernet (PoE), Digital Input/Output, and a Serial port (RS232/422/485) offering flexibility and adaptability during Retail, Manufacturing, and Smart Building system integration. One DC cable provides voltage input to the IOBOX and Nano IoT PC simultaneously, saving customers the extra burden of an AC/DC power transfer in industrial DC power supply environments.
