INTEGRATION AND TEST
The Eagle II module has been designed to minimize the amount of time required for
integrating and testing the application. By being fully GSM Type Approved, the Eagle II
module provides seamless integration into the GSM network.
integrating and testing the application. By being fully GSM Type Approved, the Eagle II
module provides seamless integration into the GSM network.
The integration issues for the application can be narrowed to the utilization of the AT
commands and the use of the GSM functionality. Coverage and signal quality may be
evaluated by using the LED of the on-board status indicator. Additional network
information can be determined by using AT commands.

Using the Eagle II Developer's Kit to Reduce Development Time and Effort
The Eagle II Developer’s Kit can also speed the development and implementation of an
application. This kit provides a platform for the development of an embedded application
and can easily be tailored for custom applications. The kit also provides a significant
amount of pre-developed software intended to speed the development of the application
and to reduce the time required for bringing a new device to market.

Integrating the Eagle II Module
Note: Generally, all interfaces that are externally available to the end user need to
be ESD-conditioned and terminated in some way. Many of these interfaces should
not be connected with power applied.
be ESD-conditioned and terminated in some way. Many of these interfaces should
not be connected with power applied.
At the highest level, this is done using some type of GSM test equipment (such as, Racal
6103E), a computer, and a serial interface tester. The GSM test equipment must be able
to simulate a GSM call and measure the key parameters related to the module.

to simulate a GSM call and measure the key parameters related to the module.
Additionally, the serial interfaces and some minimal SIM functionality can be verified by
sending AT commands to the Eagle II module.
sending AT commands to the Eagle II module.
All of this needs to be verified at ambient as well as extreme conditions.
