> 3.5.3 | Switch off TC65 Terminal

> There are several ways to turn off the TC65 Terminal:

> • | Software controlled shutdown by AT^SMSO command: The AT^SMSO command lets the TC65 Terminal log off from the network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to Power-down mode. In this mode only the RTC stays active.

> • | Software controlled shutdown via ON/OFF push button or ONOFF line at IO interface con nector: The TC65 Terminal will be switched off by pressing the ON/OFF push button or by activating the ONOFF signal for >1s. The shutdown behavior is identical to the behavior when using the AT^SMSO command.

> • | Shutdown via EMEROFF line (power supply connector): The TC65 Terminal will be switched off by activating the EMERGOFF signal for >1s. All information stored in the volatile memory will get lost.

> • | Automatic shutdown: This takes effect when the board temperature is out of range or when undervoltage or overvoltage conditions occur.
