Controls and Indicators Interface
48 G30 - Module Hardware Description December 15, 2009
A DC resistance below 100kohm (+10%) is defined as a valid antenna connection, and the
ANT_DET output signal is set high.
Note: Antenna detect indicator is valid after 2 second from power-up only.
GPRS Detection
The GPRS output signal indicates the network GPRS connection status. When G30 is connected
to a GPRS network, this signal is enabled. When G30 is not connected to the GPRS network this
signal is disabled.
General Purpose I/O
The G30 incorporates 9 general purpose IO signals in the 81 pin LGA interface, or 8 general
purpose IO signals in the 70 pin connector interface for the user application. Each GPIO signal
may be configured and controlled by AT command. These signals may be used to control or set
external application circuits, or to receive indications from the external application.
