Help for TouchWindow Users (Windows 95 & Windows for Workgroups 3.11) Contents I. Windows 95 New Technology Troubleshooting The TouchWindow is not getting power The TouchWindow is connected to your computer, but is not recognized The TouchWindow is connected to a port that is in conflict with another device. II. Windows for Workgroups 3.11 Troubleshooting I. Windows 95 New Technology If you have an older TouchWindow that has a resolution of 256x256, you may want to upgrade to our latest model, with a resolution of 1024x1024, which provides you with greater control and precision. For more information, contact our customer service department at 800-362-2890. Troubleshooting If Windows 95 has trouble running the TouchWindow, this may be due to one or a combination of the following problems. If the suggestions below do not solve the problem, refer to your TouchWindow manual for more detailed troubleshooting information. If you still do not find an answer there, please call Edmark Technical Support, Monday through Friday, 8 a.m. to 5 p.m. (Pacific Time) at 800-528-7158. Extended hours, evenings and weekends, vary with the season. A. The TouchWindow is not getting power. Check the TouchWindow for loose connections. B. The TouchWindow is connected to your computer, but is not recognized. This is most likely caused by non-standard serial, interrupt request (IRQ), or port settings. To correct this problem, you must know the address and IRQ setting of the port that is connected to the TouchWindow. If you know these, follow the instructions below to fix the problem. (If you do not know these, contact Edmark Technical Support for assistance.) 1. Check to make sure that the TouchWindow control panel is closed. 2. Run the Registry Editor. There is no icon for the Editor, so you must run it from the "Start" menu. Click on "Start" and locate the "Run" option. 3. Click on the "Run" option. 4. Type "REGEDIT". 5. Click "OK". 6. Locate the item "HKEY_LOCAL_MACHINE" and click on the plus sign (+) in front of this line. This should reveal a list of sub-folder items. 7. Now click the plus sign (+) in front of "System". 8. Locate the entry "CurrentControlSet" and click once on the plus sign (+) in front of this item. 9. Locate the entry "Services" and click once on the plus sign (+) in front of this item. 10. Locate the entry "Class" and click once on the plus sign (+) in front of this item. 11. Locate the entry "TouchWin" and click once on the plus sign (+) in front of this item. 12. Locate the entry "0000" and click once on the plus sign (+) in front of this item. This last item should reveal a list of entries on the right-hand side of the Registry Editor window. 13. There are three items on the right-hand side of the Registry Editor window that may need to be edited; change these as needed: IRQnum Interrupt request number PortAddress Communications port address PortName COMx To change a setting, double-click on the item that you wish to change. You will then see a dialog box similar to the one shown in Figure 2. (For example, if you want to change the IRQnum from 4 to 5, double-click on "IRQnum". Remove the number 4 and type in the number 5. Click "OK". Don't worry about the other settings in this dialog box.) After the changes are made, open the TouchWindow control panel to turn the driver on. Do not attempt to change the port settings from the control panel or you will have to reset them in the Registry again. C. The TouchWindow is connected to a port that is in conflict with another device. Most PC computers have only two unique serial ports. If your computer has more than two, it is likely that those extra ports are sharing resources with the first two. Ports COM 1 and COM 3 usually share interrupt request 4 (IRQ 4), while COM 2 and COM 4 usually share interrupt request 3 (IRQ 3). Due to this sharing of resources, you should avoid using the TouchWindow with another device using the same interrupt. (For example, if the TouchWindow is connected to COM 2, do not use any device on COM 4, since COM 2 and COM 4 share IRQ 4.) Some possible causes of conflict are: i. Using a Serial Mouse with the TouchWindow The TouchWindow will not work on an interrupt request (IRQ) that is being used by a serial mouse. Avoid connecting the serial mouse to the port COM 1 while the TouchWindow is connected to COM 3, and avoid connecting the serial mouse to COM 3 while the TouchWindow is connected to COM 1 (because both ports generally use IRQ 4). Similarly, avoid connecting one device to COM 2 and the other to COM 4 (both ports generally use IRQ 3). However, if you reset the interrupts of these ports, so that they are not using the same interrupt, the TouchWindow should work fine. The interrupt of a particular port may be changed either through your computer's BIOS setup or by physically changing a jumper in the computer. Refer to your computer's owner's manual for instructions on changing the interrupt of a port. ii. Using a Modem with the TouchWindow Normally, a modem (external or internal) will NOT work on the same interrupt request (IRQ) as the TouchWindow; the modem will not be able to dial out. There is one exception to this rule: a modem on a primary port (COM 1 or COM 2) sharing the IRQ with the TouchWindow on a secondary port (COM 3 or COM 4) may be able to function. (The TouchWindow, however, will not respond while the modem is communicating). iii. Physically Changing Ports for the TouchWindow The TouchWindow should work on any of the four serial communications ports. The easiest way to make sure that the TouchWindow will work after changing it to a different port is: 1. Open the TouchWindow Control Panel and disable the Touch Window. 2. Restart Windows 95. It should not be necessary to turn off the computer first. 3. Open the TouchWindow Control Panel again. Use the "Find" option to find the port, then change it. Or, choose the port directly from the communications port list, then change it. II. Windows for Workgroups 3.11 Troubleshooting Using the TouchWindow with Windows for Workgroups may require some system modifications. Should you encounter problems installing the TouchWindow, try the following: 1. Replace the Serial.386 file in your C:\WINDOWS\SYSTEM directory with the one provided on the TouchWindow installation disk. This is a maintenance file provided by Microsoft that enables "High Speed" serial ports (with 16550 UART) to work properly with Windows for Workgroups. To replace the Serial.386 file, first insert the TouchWindow installation disk. Then, at any DOS prompt, type the following: RENAME C:\WINDOWS\SYSTEM\SERIAL.386 SERIAL.BAK COPY A:\WFW\SERIAL.386 C:\WINDOWS\SYSTEM (Note: "A:\" represents your floppy disk drive, and "C:\" represents the drive or directory on which Windows is installed.) ** You must shut OFF your system, pause for a few (5) seconds, and restart your system for all changes to take effect. ** Detailed information on the new Serial.386 file can be found in the MSREADME.TXT file found on the TouchWindow installation disk, in the WFW directory. To view this file from the DOS prompt, type: EDIT A:\WFW\MSREADME.TXT (where A:\ represents your floppy disk drive). 2. If--after replacing the Serial.386 file as described above--the TouchWindow still fails to respond, an additional modification may be required. To make this modification, follow these steps: i. From Program Manager, click the "File" menu and select "Run". ii. Type: sysedit iii. Press the ENTER key. iv. Click on the Window titled "C:\WINDOWS\SYSTEM.INI" v. Scroll down and look for a line that says: device = *vcd vi. Insert a semicolon in front of this line so that it now reads: ;device = *vcd vii. Click the "File" menu and select "Save". viii. Click the "File" menu again and select "Exit". ** You must shut OFF your system, pause for a few (5) seconds, and restart your system for all changes to take effect. ** 3. If you are still experiencing difficulty, you may be encountering a conflict with your Windows mouse driver. You can try installing a different mouse driver to fix this problem. (The Logitech mouse driver is usually compatible with the TouchWindow.) If you do not have a standard Microsoft-compatible mouse, then you will need to contact Edmark's Technical Support department for further assistance. To change your Windows mouse driver, follow these steps: i. From Program Manager, open the "Main" group and double-click the Windows Setup icon. ii. Click the "Options" menu and select "Change System Settings". iii. Change the Mouse driver from its current setting to "Logitech". If the mouse driver is already set to Logitech, try changing it to "Microsoft/PS2 style". iv. If prompted, ensure that you install from the disk; do not use the existing driver. v. Follow the on-screen instructions. =========================================================================== Copyright (C) 1995-1996 Edmark Corporation. All Rights Reserved.
