This document describes the Pin Keypad Device (PIN) classes based on the basic architecture of J/XFS which is similar to the JavaPOS architecture. It is event driven and asynchronous. Three basic levels are defined in JavaPOS. For J/XFS this model is extended by acommunication layer, which provides device communication that allows distribution of applications and devices within a network. So we have the following layers in J/XFS : - Application - Device Control and Device Manager - Device Communication - Device ServiceApplication developers program against control objects and the Device Manager which reside in the Device Control layer. This is the usual interface between applications and J/XFS devices. Device Control objects access the Device Manager to find an associated Device Service. Device Service objects provide the functionality to access the real device (i.e. like a device driver). During application startup the Device Manager is responsible for locating the desired Device Service object and attaching this to the requesting Device Control object. Location and/or routing information for the Device Manager reside in a central repository. To support Pin Keypad devices the basic Device Control structure is extended with various properties and methods specific to this device which are described on thefollowing pages.
