The modem cable should have a round mini-DIN 8 connector on one end, to
connect to your Macintosh. On the other, it should have a 25-pin female
connector. An adapter connects the 25-pin end of the Macintosh modem
cable to the 9-pin end of the QUALCOMM data cable. For connection
details, see “Connecting Macintosh Components” on page 57.
Both the Macintosh modem cable and the adapter must have specific pin
configurations to work with Globalstar data. For pinout details, see Table 1.
QUALCOMM Globalstar Hands-Free Car Kit Cable
To use Globalstar data service in a vehicle equipped with a QUALCOMM
Globalstar Hands-Free Car Kit, you need one additional cable: a serial cable
with a male 9-pin connector on one end and a female 9-pin connector on the
other. This is the same type of cable as the optional extension cable, only
shorter.
This cable connects the GEM (Globalstar Electronic Module) box of the car
kit to a laptop computer. For connection details, see “Connecting Car Kit
Components” on page 107.
