M851 WristApp GUI Plug-in Design Guide
Rev 1.0
2 System Overview
This part of the documentation describes how the system is integrated as a whole. The PIM is the main
application that handles all of the different parts of the system. When you double click on an application in
the mode list, the PIM either launches the built-in mode editor if the mode is an internal application, or it
launches the WristApp GUI Plug-in if the mode is a WristApp and has a GUI Plug-in associated with it.
The PIM also handles calling the module that handles communicating data with the watch. Finally, the
PIM contains all of the data editors for each of the built-in modes. The data-editors themselves handle
import plug-ins that allow you to import data from different sources such as CSV files or schedules over
the Internet. The simple diagram shown below represents the Timex Data Link USB system.
