Can I use the QuikRuler with my Ridgid Super LII Plus digitizer?

[The QuikRuler works without any additional cables with the Roll-Up Digitizer however to use it with the SLII+ you must purchase the optional cable kit which includes a separate power supply for the QR. The QuikRuler will only work with Super L series tablets which have the grey colored Super LII+ controller. [Will not work with Type 5 or 5A (Black Box) controllers]

How can I test my GTCO Digitizer?

THIS TEST ONLY APPLIES TO THE SUPER L, SUPER LII AND SUPER LII+ (with Type 5, 5A and Grey Box Super L Controllers) These tests are not Valid for the Super LIII and Super LIV. (Black Plastic Box Controllers)

[When a digitizer does not work it is normally because of 3 possible reasons. 

1. The digitizer is defective! 
2. The Serial Interface (Com Port) on your computer is defective! 
3. Your application or Windows WinTab driver is not setup correctly. 

The following procedure covers testing the digitizer, once you eliminate this possibility you can get your IT support person or a technician to check out your serial port. This procedure requires you to first download the GTCOTEST Program from our Web site or to locate this program on disk 1 of your driver set that was provided with your digitizer. 

1. To download the GTCOTEST.EXE program go to http://www.gtco.com/files/gtest.exe and download this and install to your computer. (You need to install this while in Windows)

2. Restart Windows by selecting [START]-> [SHUTDOWN]->[RESTART IN MSDOS MODE] , this will start your machine into DOS, we want to eliminate Windows from this procedure in order to test just the Digitizer. (With Win2000 and XP you may need to find a bootable DOS disk, to boot into plain DOS or if Wintab is not loaded you can open a cmd box (Start -> Run - type "cmd" )

3. Once in DOS find the GTCOTEST program by going to the MS-DOS Folder/Directory where you downloaded it. Use the DOS "Dir " command. Say the file was placed in the GTCO Folder on your C: Drive then type ' CD \GTCO ' to verify you are in the correct folder type " dir [ENTER] and you should see the GTCOTEST.EXE program listed. 

4. Now type GTCOTEST [ENTER] -> this will start the test program. 

5. Select communication and make sure you select the correct com port. 

6. Select super set code "01" on your digitizers superset menu. If your digitizer does not have a super set menu then using the dip switches set the tablet to the following: high resolution binary, 9600 baud, 8 data bits, 1 stop bit, no parity, continuous mode. The rest of the settings are not critical for this test. 

7. Now select Output from the menu option on the right hand side, select high resolution binary and voila you should see the co-ordinates coming from the table. Move the cursor or pen on the tablet to the bottom left corner and the co-ordinates should read close to 0.0000,0.0000 move to the top right and the number should be much larger. 

8. To test the grid you will need to run the read diode diagnostic, copy down ALL the 1's and 0's exactly as displayed and fax them to our support department. If you have a printer attached to your LPT1 port you may be able to do a print screen from the diode display. A musical tone at power up usually indicates a bad diode in the grid, occasionally this could be due to a defective power supply. Voltages are listed at this link.

9. There are other tests under the diagnostic menu, to interpret them you may need to call our technical support department. Calls for digitizer support while under warranty are free, after the 1 year warranty period the support department will charge you $75.00 per incidence. Windows 2000 and XP require special settings in the tablet works driver to be changed, suggest you call support at 877-902-2979

How do I know if my GTCO Digitizer is working?

[All GTCO Super L, Super LII, Super L II+, Super LX, Roll Up's and Accutab tablets emit 4 short beeps when you apply power. If you get these four beeps then with 99% certainty the digitizer is working correctly and the problem could or should be elsewhere.]

I have an old Black Type 5 controller with a Super LII tablet, can I still obtain a power supply for this?

[Yes, the model power supply is a DP-UPS and available from stock. In fact this Power supply will also work with the type 5A (Black Colored) controller - 9 pin D Shell connector]

My GTCO System uses a controller inside my computer, think it is called a DigiPad PC, can I use this with my new PIII-600 system?

The DigiPad PC was obsoleted about 10 or more years ago. This controller was designed to work with 286 and 386 computers and will not work with the new high speed systems available today. We do however offer an upgrade controller that will allow you to use this tablet and cursor, the part number is: UPGDPC2SLII - Call 1-800-663-6001 for a quote or email: sales@interwld.com
There are very limited quantities of these controllers and once gone that is it. (dated July 2006)

Will the Super L II tablet with Type 5 or 5A controller work with Windows 98/98ME/NT,2000 or XP?

Yes, all GTCO controllers that have been sold in the last 20 years will work with Win 3.1, 95, 98, ME, NT, 2000 and XP. You will require the latest Wintab driver which can be downloaded from our web site at Here Select the correct one for your Operating System.]

Set the switches on the controller as follows
