Problems can arise when your hardware device is too old or not supported any longer. Elo uses a three-point calibration sequence that accepts touch screens with any orientation of the X or Y-axis, whether it’s in landscape or portrait mode.
Its an elo touchscreen using a serial port. After touching all 3 targets, the screen will show 'Accept' and 'Retry' buttons. The screen stays the right way up, its just the 'touch' that has moved. The Elo calibration tool is used to calibrate touch recognition on supported Elo touch screen monitors.
This will help if you installed an incorrect or mismatched driver. Video Alignment (Calibration) ST older (6.0) drivers Video Alignment (calibration) ensures that the mouse cursor appears at the position of touch. When I switch off my windows 8 PC, its seems to have forgotten the calibration that I did with the touchscreens driver software and has rotated the touch 180 degrees and I have to do it again. Try to set a system restore point before installing a device driver.
It is highly recommended to always use the most recent driver version available. The solid-state touchscreen and controller provide increased levels of reliability and longer life expectancy, resulting in a drift-free response and a low-maintenance unit that requires no recalibration. The complete system resists impacts, scratches, and vandalism and is also unaffected by moisture, heat, rain, snow and ice, or harsh cleaning fluids, making it ideal for outdoor applications. If eloconfig is not found, the driver loads default calibration values.
Upon reboot, the driver references this file for calibration data. DirectTouch consists of a 7.8 mm sensor with tempered glass outer layer, and ThruTouch works through a customer-installed outer layer. EloTouch Solutions Support Elo Linux Drivers - Calibration If calibration must be repeated after every reboot: Calibration is stored in the file. Projected capacitive technology enables touches to be sensed through a protective layer in front of a display, allowing touchmonitors to be installed behind store windows or vandal-resistant glass.
