2.2.1 Wireless Data Network
The Wireless Data Network provides the information bridge between the Actsoft servers
and the TTU-2830™. Wireless data networks can take a variety of forms, such as cellular
networks, satellite systems or local area networks.
2.2.3 Backend Software
Backend software is provided by Actsoft. Regardless of its purpose, one of its primary
functions is to parse and present data obtained from the TTU-2820. This allows the
application to do any of the following:
•
Display location database on reports received from the TTU-2830™in a variety of
formats
•
Present historic information received from the TTU-2830™, typically in a
report/chart style format
•
Request location updates from one or more TTU-2830s™
3 Hardware Overview
3.1 Location Messaging Unit-TTU-2830™
Anytime the sub assembly is shipped and it is not fully packaged in its final housing it
must be sealed in an ESD safe bag.
Electrical Over-Stress (EOS)
The GPS receiver can be damaged if exposed to an RF level that exceeds its maximum
input rating. Such exposure can happen if a nearby source transmits an RF signal at
sufficiently high level to cause damage.
Storage and Shipping
One potential source of EOS is proximity of one TTU-2830™GPS Antenna to another
TTU-2830™GSM Antenna. Should one of the units be in a transmit mode the potential
exists for the other unit to become damaged. Therefore any TTU-2830™GPS Antenna
should be kept at least four inches apart from any active TTU-2830™GSM Antenna or
any other active high power RF transmitter with power greater than 1 Watt.
3.1.2 Battery Back-up devices
Please properly dispose of the battery in any of the CalAmp products that utilize one, do
not just throw used batteries, replaced batteries, or units containing a back-up battery into
the trash. Consult your local waste management facility for proper disposal instructions.
