Did the software work in the past?
If the software package worked with the tablet in the past, then the problem lies with the new setup.
Troubleshooting chart
The following table lists common DrawingBoard III problems, their causes and their solutions.
Frozen screen
pointer
Problem Cause Solution
Pointing tool is in “sleep” mode.
Press any button on the tool.
Menu strip is in configuration mode. If the configuration light is on, click on the
Config/Exit key on the menu strip.
Tablet plugged into the wrong serial
port on the computer. Check that the serial port used is correctly
identified in your software application.
Tablet not powered correctly. Check that the power cable is installed correctly.
Batteries low in pointing tool. Replace the batteries in the pointing tool.
Software application set up incor-
rectly. Check that the tablet is identified in your soft-
ware application.
Another device is connected to a
COM port that shares the same IRQ
as the tablet COM port (i.e., your
tablet is connected to COM1 IRQ4
and your modem is connected to
COM3 IRQ4). Move one of the devices to another COM port.
Contact your system manufacturer for assis-
tance in relocating the device.
Software application set up incor-
rectly. Check that the tablet is identified in your soft-
ware application.
Unable to use the
entire tablet
surface Incorrect format selected. Check your selections in the menu strip.
Tablet’s frequency setting may
conflict with the display. Alternate the pointing tool’s frequency. (See the
Reducing monitor frequency section earlier in
this chapter.)
Screen pointer
appears to shake
or jitter Tablet is set too close to the screen
monitor. Move the tablet farther away from the screen.
Check all the connectors. Is the tablet still plugged into the same port? If yes, reset the tablet by unplugging
and replugging the power supply and restart the software.
Did you reset or power down the computer?
During reset and power on the computer can send meaningless characters out the serial port and this can
disable the tablet. Reset the tablet again.
Have you installed any new software or hardware? Remove it from your system and see if the problem goes
away.
Did you move any cables?
If you are using a PC, did the new software alter your AUTOEXEC.BAT file?
Have you updated the software or its drivers?
Are you loading another mouse driver?
Did you reinstall the software, perhaps after a problem with your hard drive? Double check your installation
procedure and the driver you selected.
Reinstall the software from its master diskettes. The program files may have been corrupted.
