Connecting to the Internet with CAR-550
2.1
Configuring
Your PCI
Express Mini
Card
The CAR-550 is a carrier card for PCI Express Mini Cards. Those mini cards can
interface with a host using either PCI Express or USB 2.0 connectivity.
The CAR-550 only gives access to the USB 2.0 connectivity. It connects the PCI
Express mini card USB pins to the USB host port on the CPU layer.
Although you can use the CAR-550 with various types of PCI Express mini
cards, this manual focuses on using a Sierra wireless MC8790 card that offers
UMTS/HSPA and quad-band GSM/GPRS/EDGE network access for roaming on
high-speed networks worldwide.
Note that CAR-550 is only supported by the UEIPAC.
2.1.1
Prerequisites
You need to purchase a data plan with a cell phone provider that supports UMTS
and/or GSM/GPRS. ATT and T-Mobile provide such a service in the USA.
Once you purchase a data plan, you will receive a SIM card that you need to
insert in the CAR-550 before being able to establish a connection.
Don't forget to activate your account as soon as you receive your SIM card
(usually done over the phone or on-line).
2.1.2
Manual
Configuration
From the UEIPAC point of view, the wireless modem is seen as a serial port to
which it can send Hayes AT commands as if it were an old fashioned RTC
modem.
UEIPAC uses the PPP software to control the modem and configure a network
connection with your phone provider.
