6. Getting Started
After applying the wire harness to the Vehicle Unit, the device will
power up and automatically attempt to register to GSM network.
Provided that your vehicle and the device is positioned in a location
with clear un-obstructed view of the sky, the device will then start
scanning for GPS satellites to obtain its first GPS lock. This first fix
can take several minutes.
Before the device is able to operate properly, some mandatory setup
parameters need to be configured from the Control Base software or
Tracking Websites.
The following basic initializations, SIM card details and GPRS dial-up
information are required to be sent by SMS command in order to
establish communication with the server:
CCNO (included in SuperGuard Service): GSM number
assigned as Control Base number with full authorization
ID: Device ID (8 digits)
APN (Access Point Nodes) for GPRS dial-up
UserID and Password for GPRS dial-up (if required)
IP and Port of host server for data exchange
TO ACTIVATE YOUR EZT DEVICE, PLEASE CONTACT YOUR
DEALER OR TRACKING SERVICE PROVIDER.

IMPORTANT NOTE: Once your device has been
initialized, all following commands sent through
the Control Base have to use the same GSM
number (Control Center Number). To switch to a
different Control Center number at a later time,
you will need to send an Initialization command
with the modified Control Center number using
the original GSM number at the Control Base.
