Model: VSM3

Positioning Universal, Inc. - Confidential & Proprietary

3 Programming and Configuration Summary

VSM3 is programmed and configured either via the serial UART connection or via an

Over the Air (OTA) process on the cellular data network.

3.1 DMAN Server

A Device Manager Server on the Positioning Universal infrastructure automatically

updates Applications and Settings files for groups of devices. When an update of the

application or new settings are released, they are loaded into the DMAN server and

assigned to the Groups of devices that are to receive the update. The DMAN server

automatically updates devices to the latest assigned versions. In normal operation,

devices “check in” to the DMAN server regularly to report their health, and to check

whether they are due to get updates.

The application provides standard tracking functionality to the VSM3. The specific

operation and variations in behavior are provided via parameters included in a Settings

file. These parameter values may vary depending on the nature of the specific tracking

application that the device is employed in.

3.2 Applications

The Tracking Application is software developed to run on the VSM3 device family and

provide functions that are typically used in vehicle and asset tracking. Updates to the

application are provided by Positioning Universal to provide improvements, corrections,

and add new functionality when it is ready for release.

3.3 Settings Files

The parameters used by the application to control tracking and other functions are

contained in a settings file on the DMAN server and loaded to devices over the air. A

simple interface allows users to specify the values of relevant parameters for devices or

groups of devices. Below is an example of the settings file creation interface.

Please see the DMAN User Guide for details on how to create Settings Files.
