The USB connection of the Mini Card is connected directly to the USB port of the
UEIPAC Cube. The minicard driver is part of the Linux kernel; UEI only supports
minicards that are supported by default in Linux. No need for a user to hunt for
proprietary drivers.
The CAR-550 provides a slot and reader for the standard SIM/UIM identity cards
commonly provided by network suppliers. The card may be inserted through the
front panel of the UEIPAC, which allows the user to add or modify service
without having to open the UEIPAC housing.
External RF connections are provided through two standard SMA coaxial.
connectors. RPSMA connectors can also be supplied as an option. The coaxial
connectors for the antenna are mounted directly on the front panel of the Cube
and are connected directly to the Mini Card by flexible leads, as shown in
Figure

. These connectors can be used to connect to various antennas for Cell,
WiFi, or GPS devices.
Four annunciator LEDs are provided. One is lit whenever power is on.The others
are controlled by the three LED indicator control pins that are standard with PCI
Express Mini Cards.
The CAR-550 not only provides simple, direct connections to a wide range of
Cell/CDMA/GSM and WiFi networks, but also enables direct connection to the
satellite GPS system.
