Overview

The ÜberTracker represents a merger of GPS and Cellular technologies
into one package capable of real-time asset tracking. GPS fixes are
taken according to a user specified interval, then reported via email or
GPRS to the user's designated email address or web server according
to a user specified number of logs per report.
The ÜberTracker is designed to work with a 6V input, or between
8V and 14V with the use of the included regulator module for use in
automotive applications. It uses the Telit GM862 Quad GSM cellular
module and the US Globalsat EM406 GPS SiRF 3 GPS module.
The ÜberTracker is FCC and PTCRB certified. Use of this device
requires a SIM card with an active AT&T Wireless
preferably an unlimited account to avoid the possibility of excessive
data fees. An unlimited account is not necessary, though we do
recommend it.
If the user wishes to alleviate themselves of the hardware,

The power converter (shown in Figure 2) takes its input from a
12V source on the white (+12V) and black (negative) leads, and
should connect to the ÜberTracker (red to red and black to black)
with the included wire nuts. For noise considerations, the converter
is of linear type, and thus may become slightly warm to the touch
during operations.

The Programming adapter (shown in Figure 3) is used for setting
up the ÜberTracker with your configuration and firmware upgrades.
It plugs into a 6-pin female header inside the ÜberTracker case,
accessible by removing the four screws from the top of the
ÜberTracker.
