Overview of Menus

4.0OVERVIEW OF MENUS

There are two ways to access the AC4: the LCD on the front of the enclosure and the Service Terminal Interface, which is accessible through any computer using a communications program. Many viewing and configuration tasks can be performed through either interface, but some are available only through the Service Terminal Interface.

Step-by-step instructions for all functions appear in Sections 5.0 through 7.0. These instructions use examples of LCD screens to illustrate most functions, except those not available via the LCD.

Examples of all Service Terminal Interface screens appear in Appendix A - Service Terminal Interface, along with instructions on how to connect to the Service Terminal Interface.

Table 6 lists all AC4 functions and shows whether they can be performed through the LCD interface and where to find information.
