featuring the additional Analog Inputs 3 and 4 are automatically identified as Rev. B in this area of the screen.

3- Parameter Selection and Setting and Special Functions

This is the program’s main frame and includes several types of tabs, each of which has sev- eral buttons, menus and other User Interface objects. These tabs and the functions they contain are described in detail in the following sections.

Navigate from one set of commands to another by clicking on the desired tab.

4- File and Program Management Commands

This frame contains a variety of buttons needed to load and save the parameters from and to the controller or disk. This frame also contains the button needed to initiate a software update to the controller.

5- View Controller Connector Pinout

Clicking on this link will conveniently pop a window containing the Controller’s connector pinout.
