2 QUICK BENCH SET-UP
Your GSP-1620 Modem Integrator’s Kit contains a
QUALCOMM Globalstar GSP-1620 Satellite Data Modem.
This chapter tells how to quickly set up the GSP-1620 modem
on a test bench so that you can interact with it, including the
following topics:
• Connecting hardware components as appropriate for a
bench setup
• Providing power to the modem
• Setting up HyperTerminal to talk to the modem and
query its status, using modem AT commands
Keep in mind that the quick bench setup shown in this
chapter differs from the setup you might use for developing
applications, integrating modems permanently into OEM
products, or for field installation.
For example, in the quick bench setup, you communicate with
the modem by typing AT commands into HyperTerminal,
whereas a SCADA application will communicate with the
modem using AT commands embedded within its code.
Also, in the quick bench setup, you can use the cables
provided in the kit to connect to the modem ports and
antenna, whereas for a SCADA field installation, OEMs will
make custom cables.
Note
Examples in this chapter assume you are connecting a Windows PC to
the modem.
