This page contains answers to common questions handled by our support staff, along with some tips and tricks that we have found useful and
presented here as questions.
Note: In these answers we will follow a few shorthand conventions for describing user-interface
procedures. Key combinations will be presented like this: Ctrl+Alt+Delete, which means that you should press and hold down the Control key, the Alt key, and the
Delete key at the same time. Menu selections will be presented like this: File > Open, which means that you should open the File menu, and then make the
Open selection.
The video refresh rate for Windows should be set to no greater than 60 Hz. To modify this setting, either connect a regular CRT to your computer or boot into
Windows Safe Mode. Within the Control Panel, open the Display icon and search for the Refresh Rate setting depending on your operating system.
The monitor's touchscreen controller is not communicating properly with your computer system. To rectify the problem, try
the following:
For touchscreens with TC-2000 controllers (Model FPx-2xxx), the touchscreen power may need to be recycled. This is often the case whenever the monitor has been moved from computer to computer
and/or the type of controller connector has been changed (from serial to USB or vice versa). After shutting down your computer, unplug and replug the power supply cable from the back of
your touchscreen. Reboot your machine.
Check that the touchscreen serial cable is properly connected between your touchscreen and your computer serial (COM) port.
The serial (COM) port that the touchscreen cable is connected to must be active. Depending on your operating system, go to Control Panel > System > Device Manager >
Ports, Coms and LPT and verify that the chosen COM port is present.
If the COM port is absent, then it must have been disabled either by the computer's BIOS or by another device, other than the touchscreen, using same the resources
(IRQ and I/O) that the COM port requires. If the former case is true, you must re-enable the COM port from the BIOS. If the latter case applies, you will need to either
assign different resources to that device or connect the touchscreen cable to a different serial port. You may need to reboot the system before the changes can take take effect.
If the COM port is present but crossed out, double click the COM port. Under the General tab, remove the checkmark from the "Disable in this hardware profile"
checkbox and click on "OK". You may need to reboot the system before the changes can take effect.
If the COM port is present but contains an exclamation mark, another device other than the touchscreen may be using the same resources (IRQ and I/O) that the COM
port requires. You will need to either assign different resources to that device or connect the touchscreen cable to a different serial port.
If the COM port is neither crossed out nor contains an exclamation mark, then a serial device other than the touchscreen is using the COM port. Either disconnect that
device from its current serial port and replace it with the touchscreen serial cable or connect the touchscreen serial port cable to a different serial port. You may need
to reboot the system before the changes can take effect.
Before permanently accepting new video settings, some Windows 2000/XP video card drivers require that the monitor type of the touchscreen be properly identified as a Flat Panel. Go
to Control Panel > System > Hardware > Device Manager. Double click the "Monitor" icon and then the "Default Monitor" listing. Under the Driver tab, click on Update Driver > Next > Display a
list of the known drivers for this device...etc. > Next > Show all hardware of this device class > Digital Flat Panel (preferred resolution) > Next > Finish.
After touching all 3 calibration crossairs, you must press "Yes" at the "Check Video Alignment" prompt within 30 seconds to save the alignment/calibration settings. If you have done this
but the cursor remains offset from your touch, you may have to re-run the alignment/calibration process. It is recommended that you use the
touchscreen stylus for pinpoint alignment.
The touchscreen connected through the USB port will work up to 15' away from the computer. The touchscreen connected through the serial port will work up to 50'
feet away from the computer.
