External Keyboard and PS/2 Mouse Port

The external keyboard and PS/2 mouse port allows you to connect an external full-sized
IBM AT-enhanced keyboard. When an external keyboard is connected, both the built-in
keyboard of the notebook and the external keyboard can be used simultaneously.
The NEC Versa 550 also provides an optional Y-connector adapter allowing simultaneous
use of external AT-enhanced keyboard and PS/2 mouse. When an external PS/2 mouse is
connected using the Y-connector, the built-in trackball will automatically be disabled.

VGA port

The 15-pin female VGA connector allows you to connect an external VGA monitor that
supports up to 1024x768 pixels resolution. When displaying on the external VGA monitor
alone, the VGA port can support resolution at 800x600 at 256 colors and 1024x768 at 16
colors for the NEC Versa 550D1 and 640x480 at 64K colors, 800x600 at 256 colors, and
1024x768 at 256 colors for both the NEC Versa 500D2 and 550D2.

NOTE: When connecting an external PS/2
mouse, it is required that you power off the
computer first before connecting the PS/2
mouse. This way, the system can detect the ex-
ternal PS/2 mouse and disables the built-in track-
ball device.
