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-12x0™ 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-12x0™ is capable of sending and receiving. This interface allows System Integrators to communicate directly with
TTU-12x0'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-12x0™ in a variety of formats
Present historic information received from the TTU-12x0™, typically in a report/chart style format
Request location updates from one or more TTU-12x0s™
Update and change the configuration of one or more TTU-12x0s™
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 LMU Manager™
LMU Manager is the primary configuration tool in the CalAmp system. It allows access to almost every feature available to
the TTU-12x0™. Unlike the backend software, it has the option of talking directly to an TTU-12x0™ or making a request
forwarded by the LM Direct™ server.
For further details on using LMU Manager, please refer to the LMU Manager Users Guide.
