Modem Integration Guide
Figure 13 shows a typical connection from an external processor to the Enfora Enabler III-G module,
using the external PWR_CTL_SIGNAL solution. The Enfora Enabler III-G can be powered on by using
the PWR_CTL_SIGNAL signal. When using PWR_CTL_SIGNAL, the I/O or serial lines can be at any
voltage state desired. It is suggested that the I/O and serial lines be tri-stated or set low when the
GSM0308 is shutdown for an extended period of time to conserve power.
