32TouchWare for Windows User's GuideConnectionCommunication PortDisplays the COM port used for the touchscreen hardware connection.If you have two serial devices operating together, such as a touchscreen anda mouse, be sure each device uses a unique COM port and IRQ number.For example, the mouse can use COM1/IRQ4 and the touchscreen can useCOM2/IRQ3. Using the same COM port or IRQ creates device conflicts.The touchscreen must have a unique IRQ; it cannot share an IRQ withanother device.Use the Microsoft Hardware Conflict Troubleshooter (available inWindows Help) to try and resolve this problem.Find TouchscreenWhen you select the Find Touchscreen option, TouchWare:• Scans the available communication ports supported by Windows for atouchscreen. Find Touchscreen searches the baud rates used by thetouchscreen.Note: TouchWare will only work with COM ports configured, recognized,operational and supported by Windows at the time of install.• Tries to communicate with the touchscreen controller.• Waits for the touchscreen controller to respond.• Requests information about the touchscreen and its controller.If TouchWare does not find the touchscreen, check that the touchscreen isconnected properly, and then repeat the search. Refer to Chapter 4Troubleshooting the Touchscreen for more information on what to do ifyour touchscreen is not found. Note that this option cannot search anyCOM ports in use by other applications.Verify that any previously loaded hardware/software (i.e., mouse ormodem) that used the same COM port as your touchscreen has beenuninstalled. Just because the hardware is disconnected doesn’t mean thatthe software isn’t claiming the port. Ensure that all components arecompletely removed from the System files.
