DECS-200 Human-Machine Interface 2-1
SECTION 2 • HUMAN-MACHINE INTERFACE
INTRODUCTION
This section describes the DECS-200 human-machine interface (HMI), illustrates how to navigate through
the menu screens, and explains how to use the front panel interface to view and change settings.
FRONT PANEL CONTROLS AND INDICATORS
The front panel HMI consists of a backlit liquid crystal display (LCD), six pushbutton switches, six LED
indicators, and an RS-232 communication connector. The LCD displays DECS-200 settings and
excitation system information through the use of a structured menu. Menu screens are viewed and
settings are changed by operating the front panel pushbuttons. Active conditions are annunciated by the
front panel LEDs. The RS-232 connector (Com 0) enables communication between the DECS-200 and a
PC operating BESTCOMS software.
Front panel HMI components are shown in Figure 2-1 and described in Table 2-1.
