Computer checklist
Is the computer plugged into a live outlet? Did you turn on the computer?
Does the computer work with any software? Try one of your other programs. If the computer has a diagnos-
tic diskette, use it.
Is your software package installed correctly?
Does the serial port work? The only way to test the port without special equipment is to reinstall something
that has worked in the past and test if it still works.
Have there been any recent electrical storms in your area that may have damaged your equipment?
Software checklist
Does the tablet work with some software?
If your tablet currently works with some software packages, you know that the tablet, serial port, and computer
work.
Even if the software package you are trying to install and the software that is working both support the same
tablets, it does not always mean that you can use the same tablet settings. The output format may be the
same, but the communications protocol, resolution, operating mode, and data rate may be different. Check
your software’s requirements.
Call the software manufacturer. Perhaps the software package has a problem with another component of
your system.
Tablet checklist
Is the tablet power supply plugged into the serial connector and into a live outlet?
Is the tablet power switch on?
Does the power light glow steadily when the pointing tool is inside the drawing area? Does it blink when the
pointing tool is outside the drawing area?
The power light will blink if the pointing tool has gone into sleep mode. Press any button on the tool to
activate it. If the power light continues to blink and the pointing tool is in the drawing area, change the
pointing tool’s battery.
Are all cable connections tight?
Power cable to serial connector?
Pointer cable to tablet?
Serial cable to tablet?
Serial cable to computer? Check that the cable is connected to the serial port specified in your software
package.
Is the tablet set up according to the software recommendations?
Are any of the connector cables or receptacles damaged? Check for bent pins, cut insulation, and loose
wires.
