  • Page 20: Overview

    This chapter details on using the UART signals of the B2B connector rather than the Micro USB port to control VT-MOB-LTE1T-PB (the “cellular card”), and this setup is referred to as the UART DTU mode. Since the AT commands are transmitted between the cellular card and the host computer via the UART signals, the port using such signals is called the serial AT port.
