PHYSICAL INTERFACES OF THE EAGLE II
MODULE
The Eagle II module provides the following interfaces:
Antenna connector, which allows the Eagle II module to communicate with other
GSM devices.
Signals on the 60-pin I/O connector allow the carrier board of the application to
communicate with the Eagle II module. Two V.24 serial data interfaces allow
simultaneously holding a circuit-switched call while sending and receiving SMS
messages
LED indicator provides a visual indicator for the operational status of the module
Refer to the Eagle II Interface Control Drawing (ICD), Document # 06700103, for the
physical locations of these interfaces.
Note: For optimum performance and reliability, ensure that all mating connectors
have a minimum of .76 microns (30 micro-inches) of gold plating on contact
surfaces.
Antenna Interface
The Eagle II module is designed to support interchangeable antenna types, provided that
each antenna has 50-ohm impedance and has been tuned to the frequency band
intended.
The Eagle II module provides a connector for either a female SMA-type antenna
(standard) or a female MCX antenna (optional). This allows a choice in the type of
antenna configuration best suited for the application. The SMA-type connector is
recommended for high-vibration or mobile environments.
Input/Output (I/O) Signal Connector
The Eagle II module communicates with the carrier board via a 60-pin, dual-row, surface-
mount connector with a 0.8 mm pitch.
