LCD Display

GStatus display — The 20-column by 4-line LCD displays configuration menus and status information (see “Front Panel Operations,” below, for details).

Menu Control Buttons

HMenu button — The Menu button enters and moves through the main menu system in the ISM (see “Front Panel Operations,” below, for details).

Next button — The Next button steps through the submenus in the ISM menu system (see “Front Panel Operations,” below, for details).

Adjustment Knobs

IAdjust (horizontal) and Adjust (vertical) knobs — The Adjust and Adjust knobs change settings when used in conjunction with the picture adjustment buttons or the menu system. Rotate these knobs to change picture settings when one of the picture adjustment buttons is selected.

on

The following paragraphs detail the power-up process and then describe the menu system, the picture adjustments, and selection of executive mode.

Power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks all of the front panel LEDs and then lights only the LEDs for the previously selected output and the tied input. The self-test also displays the model name, part number, and the firmware version in the LCD display. After approximately 2 seconds, the LCD reverts to its default display cycle, alternating between two displays: one showing the inputs selected for outputs 1 and output 2, and the other showing the selected output rates (see figure 16). An error-free power up self-test sequence leaves all of the LEDs off, with the exception of the selected output’s and input’s LEDs, off and the LCD cycling through the default displays.

The selected inputs for output 1 and output 2, the picture adjustments, and other current settings are saved in nonvolatile memory. When power is applied, the latest configuration is retrieved.

NOTE: On figure 16 and all other flowcharts in this section, solid lines indicate screen changes initiated by the operator. Dashed lines indicate screen changes that are the result of a timeout function.
