parameters, PEG rules, and firmware can all be updated over the air. Our web-based maintenance
server, PULS™ scripts, and firmware, can all be updated over-the-air. PULS™ offers out-of-the-box
hands free configuration and automatic post-installation upgrades. You can also monitor unit health
status across your customers' fleets to quickly identify issues before they become expensive problems.
2 System Overview
2.1 Overview
The entire purpose behind a fleet management system is to be able to remotely contact a vehicle,
determine its location or status, and do something meaningful with that information. This could include
displaying the vehicle location on a map, performing an address look-up, providing real-time driving
directions, updating the vehicles ETA, monitoring vehicle and driver status or dispatching the vehicle to
its next pick up.

These functions, of course, are completely dependent on the capabilities of the vehicle management
application. The role of the CalAmp TTU-4530™ is to deliver the location information when and where
it is needed.
A typical fleet management system based on a CalAmp device includes the following components:
A wireless data network
An TTU-4530™
Host Device (GPS NMEA only)
An LM Direct™ communications server
Backend mapping and reporting software which typically includes mapping and fleet reporting
functions
PULS™
TTU Manager™

Basic System Architecture
2.2 Component Descriptions
2.2.1 Wireless Data Network
The Wireless Data Network provides the information bridge between the LM Direct™ server and the
TTU-4530™. Wireless data networks can take a variety of forms, such as cellular networks, satellite
systems or local area networks. Contact the CalAmp sales team for the networks available to the TTU-
4530™.
2.2.2 TTU-4530™
The TTU-4530™ is responsible for delivering the location and status information when and where it is
needed. Data requests mainly come from the following sources:
PEG™ script within the TTU-4530™
A location or status request from the LM Direct™ server
A location or status request from TTU Manager
An SMS request made from a mobile device such as a customer’s cell-phone
In some cases, it is necessary to run an application in the vehicle while it is being tracked by the
backend software. Such examples could include instant messaging between vehicles or a central
office, in-vehicle mapping or driving directions, email or database access. In most of these cases you
will be using the TTU-4530™ as a wireless modem as well as a vehicle-location device.
]2.2.3 LM Direct™ Server
LM Direct™ is a CalAmp proprietary message interface specification detailing the various messages
and their contents the TTU-4530™ is capable of sending and receiving. This interface allows System
Integrators to communicate directly with TTU-4530's™. Please refer to the LM Direct Reference
Guide for details.
2.2.4 Backend Software

Backend software is a customer provided software application. Regardless of its purpose, one of its
primary functions is to parse and present data obtained from the LM Direct™ server. This allows the
application to do any of the following:
Display location database on reports received from the TTU-4530™ in a variety of formats
Present historic information received from the TTU-4530™, typically in a report/chart style format
Request location updates from one or more TTU-4530s™
Update and change the configuration of one or more TTU-4530s™
2.2.5 PULS™
PULS™ (Programming, Update and Logistics System) is CalAmp’s web-based maintenance server
offering out-of-the-box hands free configuration and automatic post-installation upgrades. PULS™
provides a means for configuration parameters, PEG scripts, and firmware to be updated Over-The-Air
(OTA) and allows CalAmp customers to monitor unit health status across your customers’ fleets to
quickly identify issues before they become expensive problems.
2.2.6 TTU Manager™
TTU Manager is the primary configuration tool in the CalAmp system. It allows access to almost every
feature available to the TTU-4530™. Unlike the backend software, it has the option of talking directly to
a TTU-4530™ or making a request forwarded by the LM Direct™ server.
For further details on using TTU Manager, please refer to the TTU Manager Users Guide.

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.
3.1.3 Environmental Specifications

The TTU-4530™ is designed to operate in environments typically encountered by fleet vehicles,
including wide temperature extremes, voltage transients, and potential interference from other vehicle
equipment.
To ensure proper operation in such an environment, the TTU-4530™ was subjected to standard tests
defined by the Society of Automotive Engineers (SAE). The specific tests included temperature, shock,
vibration, and EMI/EMC. These tests were performed by independent labs and documented in a
detailed test report. In accordance with Appendix A of SAE J1113 Part 1, the Unit is considered a
“Functional Status Class B, Performance Region II” system that requires Threat Level 3 Testing.
The following shows the environmental conditions the TTU is designed to operate in and the relevant
SAE tests that were performed. No formal altitude tests were conducted.
