2.2.2 LMU-2600™
The LMU-2600™ 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 LMU-2600™
A location or status request from the LM Direct™ server
A location or status request from LMU 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 LMU-
2600™ 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 LMU-2600™ is capable of sending and receiving. This interface allows System Integrators to
communicate directly with LMU-2600'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 LMU-2600™ in a variety of formats
Present historic information received from the LMU-2600™, typically in a report/chart style
format
Request location updates from one or more LMU-2600s™
Update and change the configuration of one or more LMU-2600s™
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™
