External Power Control Signal (no external processor) shows a typical connection to the
Novatel Wireless M2M Enabler IIIG module in a machine-to-machine application using the
external PWR_CTL signal (when there is not an external processor controlling the power
on/off states). The RTC deep sleep functions will NOT function since the PWR_CTL pin is tied
low, the processor will never stay in a “RTC Sleep” mode. To reset the module, the power
(VBAT) must be cycled.
Figure 3-9 External Power Control Signal (no external processor)
The Power Control Signal (using external processor) figure shows a typical connection from an
external processor to the Novatel Wireless M2M Enabler IIIG module using the external PWR_
CTL signal. The Novatel Wireless M2M Enabler IIIG can be powered ON by using the PWR_
CTL signal. When using PWR_CTL, the I/O or serial lines can be at any voltage state desired.
We recommend that the I/O and serial lines be tri-stated or set low when the
GSM0308/GSM0306 is shutdown for an extended period of time to prevent any leakage
current from the processor to the modem.
