Other Parallel Devices/
Your parallel port can also be used with other parallel port devices (e.g. a tape backup unit). Your
parallel port is capable of supporting enhanced ECP and EPP transfer modes. ECP transfer mode
provides significant performance increases for transfer to 1-way parallel devices (such as printers).
EPP transfer mode provides increased performance for 2-way transfers such as those used to link
another computer to your WinBook XP5 Pro system for file transfer. You might need to check the
documentation of your device to determine the modes supported. If you need to change the transfer
mode of your printer, you can do so in the Setup program (see Chapter Six).
[Sidebar: Pencil icon: If your device is Plug and Play, it might be detected on boot. If so, you will
receive a message that new hardware has been detected and then instructions for completing the setup.
If not, then you will need to set up the device according to the instructions provided by the device
manufacturer.]
Be sure to shut down your system before connecting the device to your system to prevent damage to
your system and the parallel device.
External Monitor
You can connect an external VGA or SVGA monitor to your WinBook XP5 Pro through the video
port on the rear of the system. You can direct the output to the LCD, the external monitor or both by
toggling the LCD/CRT setting ([Fn]+[F12]).
[Sidebar: Eyeball icon: Directing the video output to both the LCD and the video monitor will slow
the video response time.]
Your external monitor might require that you change the video driver from the default driver for the
LCD screen. You can make this adjustment by clicking on the Display icon on your taskbar and then

. Select the appropriate driver and
resolution for your monitor.
[Sidebar: Pencil icon: If your monitor is Plug and Play compliant, the WinBook XP5 Pro should detect
its presence and set up the necessary drivers.]
A higher resolution on your external monitor might also mean a slower refresh rate, the speed at
which a monitor sends a new image to the screen. A cathode ray tube (CRT) sends an image vertically
down a screen one line [XP5 Pro 4.12] at a time. The whole screen is thus refreshed at a certain
interval (as the CRT cycles down the screen and then returns to the top). This speed is usually
measured in MHz (megahertz or millions of hertz), which is a unit of frequency. A refresh rate of 60
MHz will produce a slightly perceptible flicker of the screen that can cause eye strain. A rate of 72
MHz or faster will usually produce a comfortable image. Your monitor may refresh at different
frequencies depending on the resolution. Check your monitor specifications for the refresh rate, this
may help prevent eye strain.
