Frequently-Asked Questions for GTCO Brand Products

How can I get drivers for my digitizer?

Simply download the drivers from the GTCO Calcomp website or click here: DRIVERS

What is the maximum length for a USB cable?

The maximum length for a USB cable is 5 meters (197 inches). The power transferred through a USB cable that is greater than 5 meters in length will start to decrease, and the device may not function properly.

ROLL-UP III’s

What is the difference between a Roll-Up II and Roll-Up III?

The Roll-Up III has the built-in USB port. The Native USB connectivity allows power to be supplied via the USB port. Installation is quick and easy—Wintab™ applications use the Roll-Up III with our TabletWorks drivers. For non Wintab™ applications, the Roll-Up III will be restricted to serial connection setup through SuperSet Menu or Custom Configuration Menu.

Will the Roll-Up III work with Windows 98/NT/W2K/XP?

Yes. You may also need one of our TabletWorks drivers.

Does the Roll-Up III support cordless transducers?

No, the Roll-Up III can only be used with the corded type transducers.

My Roll-Up III is emitting a series of strange beeps. What should I do?

Make sure your stylus/cursor is connected tightly. Reset the digitizer. If these actions do not correct the problem, check the Help File for a chart of diagnostic tones and what they mean or call GTCO CalComp Technical Support.

I moved my Roll-Up III and now it doesn't work. What should I do?

Check the connections. Be sure that the I/O cable (the cable running from the computer serial port to the digitizer or the USB cable between digitizer and computer) is connected on both ends. If all cables appear to be properly attached, reset your digitizer using the appropriate Super Set code and listen for the tones. If you hear anything other than the four Success tones, consult the Help Files for assistance. Also, be sure you have selected the correct serial communications port in your software application

I have a separate power supply for my Roll-Up III---do I really need to use it?

Yes. If the Roll-Up III connects via serial port, the external power supply is needed to ensure the digitizer has a constant power source. This is especially true if you are using the digitizer with a laptop computer. The power supply is not needed if the Roll-Up III connects via USB port.

Why do I get dead spots and areas where the stylus/cursor jumps around my Roll-UP III?

There are a few possibilities: Pencil Marks. Pencil marks contain graphite. Graphite is a conductor and will interfere with proper functioning of the digitizer. Erase any pencil marks from the tablet. If the plans or paper resting on the tablet have pencil marks, remove the plans and see if this action corrects the problem.  Objects in contact with the digitizer. Be sure there are no metal objects (such as staples) on or below the digitizer. A Roll-Up cannot be used effectively on a metal surface. Be sure there are no electronic devices (such as a monitor, phone, radio, or even a keyboard) on the digitizer tablet because these devices can cause interference.  Dirt or film builds up. The digitizer should be clean and dry. Clean the digitizer with a mix of isopropyl alcohol and water on a soft cloth. DO NOT apply liquid directly on digitizer surface.  Static electricity. Try to ground yourself before using the digitizer. If the air is very dry, try using a humidifier. An anti-static air spray and/or grounding floor mat may also help. Clothing made of synthetic fabric also creates a lot of static electricity. If static is a problem, you may want to minimize how much synthetic material you are wearing.  Cuts or slices in the tablet. Cuts or slices in the tablet may result in dead spots. If you believe your tablet is damaged in this way, call GTCO CalComp Technical Support.

Does it matter what order I plug the stylus/cursor, power supply and I/O cable in?

Yes. For serial connection: First connect the stylus/cursor and then the separate power supply if you have one. Next, connect the I/O cable. The digitizer will emit the four Success tones when you connect the external power supply. There is no specific order for disconnecting the components. For USB connection: connect the transducer before the USB cable. There is no specific order for disconnecting the components

Can I use my Roll-Up III with the older QuikRuler?

Yes. Connect the QuikRuler the same way as with the Roll-Up II using Interface Module and interface cable provided with the QuikRuler, or call the GTCO Sales Department or your local GTCO Dealer for more information about the QuikRuler Legacy Kit.

SUPER L TABLETS

My digitizer is emitting a series of strange beeps. What should I do?

Check the ribbon cable connections on both ends. Disconnect and then reconnect the ribbon cable to be sure it is seated well. Then press the reset button on the controller. If this does not correct the problem, check your User’s Manual for a chart of diagnostic tones and what they mean or call GTCO Technical Support.

I moved my digitizer and now it doesn't work. What should I do?

Recheck the connections. Be sure that the I/O cable (the cable running from the computer serial port to the digitizer) is connected on both ends. Be sure that the I/O cable is connected to the correct port on the digitizer. If you have a standard RS232-C cable, be sure it is connected to J6 Port B. If you have a null-modem cable, be sure it is connected to J5 Port A. If all cables appear to be properly attached, reset your digitizer and listen for the tones. If you hear anything other than the four Success tones, consult your User’s Manual for assistance. Also, be sure you have the correct serial communication port selected in your software application

Can you replace the Pen tip?

Yes, to replace the pen tip, grasp the tip and pull straight out. Insert the new tip and press until it clicks into place.

What kind of batteries does the cordless pen use?

The cordless pen uses two 393 silver oxide (hearing aid) batteries. For installation instructions see the on-line Help Files. The average battery life is 750 to 1,000 hours.

What kind of batteries does the cordless cursor use?

The cursor requires two AAA batteries. For installation instructions see the on-line Help Files. The average battery life for the cursor batteries is 4,000 hours

There is no power light when the transducer is inside the drawing/active area.

Check the board’s power and be sure you are getting the normal 4 beeps on start-up. The power light will be out if the transducer has gone into sleep mode. Press any button on the transducer to activate it. When the cursor is not in sleep mode, but out of the active area, the green LED will flash. If the power light continues to be out and the transducer is cordless and within the active area, change the batteries.

The pointer on my screen shakes or jitters.

The tablet may be set too close to the monitor. Move tablet further away from screen. If you are using a small format cursor or stylus, the tablet’s frequency setting may be conflicting with the display. See the on-line Help File for instructions about changing the frequency.
