these 'hex images' are deployment 'packages' which you build/modify with the 'package builder' app, that is part of the console:
AVALANCHE PACKAGE BUILDER
The Avalanche Package Builder SDK simplifies the process of preparing and configuring software deployed to mobile devices
using Wavelink Avalanche. The SDK provides an easy-to-use graphic interface that allows a user to:
- Bundle software into the Avalanche Administrative Console and file system
- Configure the selection criteria that defines which mobile devices will receive the software
- Specify settings within the software
More detail on the Avalanche Package Builder SDK and how it is used is available in the Package Builder User Guide.

I hate to mention this, but I worked with Symbol handhelds and WaveLink stuff for around three years or so....part of a very big SAP roll-out.
