Integrating Modems into Products
This section describes the QUALCOMM Globalstar
GSP-1620 Satellite Data Modem hardware, including
mechanical descriptions of the modem, its Data, Control and
Diagnostic port signals and pinouts, DC power, and
grounding.
Using this information for your specific products, you can
create custom cables, which connect a modem (the DCE) to:
• A terminal or processor (the DTE) running custom
application software for your product — using the Data
port only, or both Data and Control ports
• An appropriate DC power source
• A Dielectric Resonator Antenna (DRA) — for information
about installing antennas and calculating cable lengths,
see Mounting Antennas On-Site on page 7-22.
Note
This section also describes the Diagnostic port, although typically it is
used only during development and for service programming.
