Using the Front Panel
Overview
This chapter is designed to familiarize you with the Excalibur Multirate DAP front panel.
It describes the functions of all buttons and LED indicators, shows you what you will see
when you first plug in the DAP, and explains how to move through the menus to enter
commands. It also contains instructions on entering unit addresses, establishing
password protection, and testing the front panel buttons and indicators.
Front Panel Components
The Excalibur Multirate DAP front panel contains eight pushbuttons, two LED
indicators, and a 48-character LCD screen. Figure 4-1 illustrates the front panel and
describes the functions of its various components.
The front panel provides an audible beeper that you can enable or disable as desired. The
beeper can be configured to sound every time a button is pushed and/or an alarm is
reported. It can also be disabled completely. (For instructions, see "Beeper" in Chapter
5.)
