Troubleshooting
Problem: I have followed all the instructions for
establishing Pen-PC communications and my Pen will
still not communicate with my PC. What else can I do?
Solution:
1. Make sure you have new, fresh batteries in your Pen.
2. Make sure you are an administrator on your computer.
Sometimes installations will be unsuccessful if you try to
install new software n a computer where you do not
have full administrator rights.
3. Unplug any devices that sync data between the device
and your PC, i.e. PDAs or digital cameras. If the icon for
the device appears in the notification area of the
windows taskbar (bottom right of the screen next to the
time display) right-click on the icon and exit the
application.
4. When you connect the USB cable to both the Pen and
PC, make sure the cable jack is pushed all the way into
the Pen and confirm that you hear the last little 'click'
when the cable is fully inserted.
5. If this doesn’t help, try inserting the USB cable into a
different port on the computer.
6. If you are using a laptop and the baud rate in the device
manager is set to 115200, try changing the baud rate in
the Device Manager as follows:
a. On your computer go to
Start
/
Settings
/
Control
Panel
and select
System
.
b. Click on the
Hardware
tab and then click on the
Device Manager
.
c. Scroll down to
Ports (COM & LPT)
and open the
drop-down list of ports.
d. Find the "Prolific USB-to-Serial Comm Port".
e. Double-click on the prolific driver and go to
Port
Settings
. Try changing the Port Settings only in
the Device Manager (not on the Desktop or Pen).
f. Try a few different settings. This should help.
