Re: GTCO CalComp Drawing Board III 34480

This tablet,when turned on,should only beep once.
It sounds like their may be a hardware problem or corrupt firmware.
Make sure you are using the correct power supply, these use a 12 volt power supply,center negative.

If this fails contact GTCOCalcomp Tech Support.

Drivers for GTCO, GTCOCalcomp or Calcomp digitizers for Windows XP, 7 and 8 can be downloaded from this url:

If you are trying to use your digitizer with AutoCad these drivers will not work and you will need to buy a driver from (They provide a 30 day free trial/demo) only works with serial RS232 interface. If your digitizer uses USB then you will need an interface kit for your specific digitizer to convert it to RS232. Most new digitizers come with USB, some have serial but require you to buy an interface kit. Contact your Digitizer supplier.

If your digitizer is a GTCO, GTCOCalcomp, Calcomp or Summagraphics brand, try these guys:
They do not know about any other brands. Wacom contact Wacom, Numonics contact Numonics. If you have Mutoh or Science Accessories or any other brand you are on your own as those manufacturers have all gone out of business as far as I know.

Does the drawing board III use WinTab for arcGIS 10?

ALL ESRI ARC Programs as far as I am aware use the Standard GTCO Tablet Works drivers. All GTCOCalcomp digitizers are or were level 1 supported by ESRI and the standard tabletworks driver will work just fine (This only applies to Windows versions of ARC, not Unix or other OS's)
Drivers can be obtained from GTCOCalcomp or from this link at the Interworld Site:

If your digitizer has a serial interface use the SuperSet code 01 or 11. If you digitizer uses USB then no superset is active or needed (This only applies to GTCO or GTCOCalcomp Digitizers)

Calcomp or Summagraphics digitizers will need to be set to 9600,8,N,1 with High Resolution Biinary output to work with Tablet works. Hope this helps you

Autocad 2008 et Drawing Board III (is there compatibility?)

If you are using the drivers supplied by GTCO, they won't work with Autocad 2008.
They are not a fully compliant Wintab driver. Check with the Autocad software to be sure of what kind of tablet driver it needs.
There is a site called that sells a tablet driver that is fully Wintab compliant.

Calcomp Drawing Board III

If you need documentation, go to and they have FREE documentation for your tablet.
It may be a software switch is turned on and is causing this problem. Also check the driver and turn off any mapping.
When you read the manual it will show you how to turn off/on the software switches on the tablet.
These tablets should boot-up in the GTCO binary mode.
