will not be able to communicate with external devices. Try replacing the cable.
Problem : I ca n’t get my Serial Infrared Port to work properly.
Actions :
• Go into the Advanced Menu of the Setup Program (under the Integrated Peripherals su b -menu) and
make sure the infrared port is enabled on COM2. If you are using Windows 95, also check that the
Advanced Menu of the Setup Program is set to the "Plug and Play OS" mode.
• You must line up the external device correctly. The Serial Infrared Port uses infrared light to
communicate with external devices. To use the port, you must have an unobstructed visual pathway
between the WinBook XP5 Pr o
’s serial infrared transceiver and the external devic e ’s serial infrared
transceiver. If the line of sight between the transceivers is blocked, communication between the
devices will stop. The WinBook XP5 Pro and the external device should be about two feet apart with
an angle of no more than 1 5
°. Some devices work best if kept at least six inches apart.
• Make sure that the transceiver windows on each device are clean. Finger prints or dust buildup may
obstruct the line of sight between the devices.
• The virtual COM port link between two computers may not be reliable if a third IR adapter (such as
a printer) is also within range. Move other IR adapters out of range.
• Connecting and disconnecting over a lo w -speed IR link or over a poo r -quality link can take a long
period of time (a few seconds), during which time the screen will appear to be frozen. To work around
this, you should use a highe r
-speed connection or attempt to improve the connection. Try realigning
the IR devices so they point right at each other, [XP5 Pro 7.6] moving the devices closer together, or
plugging in the AC power to boost power to the connection (in case of a weak battery).
Problem : My external printer is not working.
Actions :
• Make sure the printer is ready to print. Check the printe r ’s power cable to see that it is properly
plugged into the printer and the electrical outlet. Also see that the printe r ’s communication cable is
connected properly to the WinBook XP5 Pr o ’s LPT1 Port and to the back of the printer.
• If the printer is turned on, there should be a power indicator that illuminates. There is also usually an
indicator showing that the printer is "ready" or "o
n -line." If this indicator is not illuminated, check to
see that the printer has paper, and that the paper is aligned properly in the paper tray.
• The printer port may not be enabled. Check the Advanced Menu of the Setup Program (under the
Integrated Peripherals su
b -menu) to be certain that the port is enabled and set to LPT1 with an ECP
port mode.
