CHAPTER 5: Operation: On-Screen Display

5.4.3.C Show Computer Number

This item determines whether or not the computer number is displayed along with the computer label. To change this setting, press [Enter] while “Show computer number” is highlighted. A yes/no input box appears. Use the arrow keys to select “Yes” or “No” and hit [Enter]. The input box disappears and the new setting appears in the “Show computer number” field. Factory default is “Yes.”

5.4.3.D Fade Out

This item determines how long the ServSwitch continues to display the computer label after you switch to a different CPU before allowing it to “fade out.” If you set “Fade out” to anything from 1 to 254, the Serv unit will wait that number of seconds before fading out the computer label. If you set “Fade out” to 255, the unit will display the label at all times. If you set “Fade out” to 0, the unit will never display the computer label at all.

This item also determines how long the Switch displays the computer label after receiving a Display Label ([Ctrl] [D]) keyboard command (see Section 4.3.9). The Switch will display the label for five seconds if “Fade out” is set to 0, for the corresponding number of seconds if “Fade out” is set to 1 to 254, or always if “Fade out” is set to 255. Factory default is 5 seconds.

To change the fadeout setting, press [Enter] while “Fade out (seconds)” is highlighted. An “Input new value” box appears. Use the shared keyboard’s number keys to input a new value from 0 to 255 and hit [Enter]. The input box disappears and the new setting appears in the “Fade out (seconds)” field.

5.4.3.E Font

This item determines in which font the ServSwitch displays the computer label. The choices are: 8x16 modern, 8x16 classic, 16x24 modern (the factory default), 16x24 classic, 16x32 modern, and 16x32 classic.

8x16 is the size of the text in the configuration menus. 16x24 is twice as tall and half again as wide. 16x32 is both twice as tall and twice as wide. The “modern” font is a sans-serif font similar to Helvetica®. The “classic” font is a serifed font similar to Times®. The actual size of the font on the screen depends on the resolution of the input video from the CPUs. At higher resolutions the fonts are proportionally smaller, so use larger sizes to keep the labels legible.

To change the font, press [Enter] while font is highlighted. A font-input box appears. Use the arrow keys to select the desired font and hit [Enter]. The input box disappears and the new setting appears in the “Font” field.
