Enfora Enabler II-G Assisted GPS

Modem Integration Guide

Figure shows a typical connection from an external processor to the Enfora Enabler II-G A-GPS module, using the

external PWR_CTL_SIGNAL solution. The Enfora Enabler II-G A-GPS 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 MLG208 is shutdown for an

extended period of time to conserve power.
