In-Vehicle Administrator User Guide (Legacy)

This document describes the components of the myAvail CAD\AVL in-vehicle system, both hardware and software, and provides information about the design, structure and configuration of these components. The guide covers the myAvail system at a level intended for system administrators and for providing management staff a system overview.

This document provides information about how data flows within and between in-vehicle hardware components and to the backend system. Additionally, this guide provides references to various other User Guides and Quick Reference materials for detailed information about system features and various daily and less frequent operational tasks. Step by step instructions for performing technical functions such as updating software and other responsibilities are provided in the AVL Service Guide provided when the fleet is installed.

This Guide is intended for use by the staff responsible for the technical administration of the overall myAvail System, for those responsible for the myAvail in-vehicle hardware and for management staff that require an overview of the complete product.
