  • How do I install a Topaz LCD signature pad with serial interface on my computer?

    Topaz LCD tablets with serial interface require more power than can be provided by just the serial port of your PC.  Therefore these tablets are supplied with the cables needed to power the unit from the keyboard port while sending the signature data to the standard serial port.  To view the installation instructions for LCD tablets, click here. An AC wall transformer is available for those who would prefer it. Please contact the factory for more information.

    To connect your Topaz serial tablet to a network, you must utilize the ethernet adapter and cable. View the Ethernet Adapter How-To for installation.



  • How do I change the ink tip in the pen?

    DO NOT OPEN THE PEN! The pen tip is removed from the tip of the pen and replaced all from the open end of the pen. Simply grasp the tip of the cartridge and pull it out from the end of the pen. If the pen is forced open, it will be virtually impossible to re-assemble without special factory tools.
