Portrait and landscape modes
NextWindow's touch screens can be installed in portrait or landscape orientation. The calibration procedure allows the touch screen to align itself correctly with the picture on the display screen. Note that, the display itself may need software to rotate the picture into portrait orientation.
Identifying the optical sensor locations
NextWindow's touch screens incorporate two optical sensors in two adjacent corners of the screen. For diagnostic purposes, it may be necessary to identify the sensors. The sensors are always numbered '1' and then '2' in a clockwise direction along the side of the screen that contains them. For example, if the sensor side is the top of the screen, the top left is sensor 1 and the top right is sensor 2.
On some products, the section that supports the two sensors and the connections to the touch screen is known as the "camera bar."
You can rotate a NextWindow's touch screen to the required orientation, fix to the display screen, and then calibrate.
The optimum position of the camera bar for different models is as follows.
2100 Models
The 2100 touch frames normally have the camera bar at the top for both portrait and landscape applications.
2700 Series Models
The 2700 touch overlays are designed so that the camera bar is at the top for both portrait and landscape modes and must be ordered as either a landscape or portrait model.
Calibrating a NextWindow USB touch screen?
All of NextWindow's USB touch screens use the same simple one-time calibration procedure. For instructions, see Calibrating a NextWindow USB Touch Screen.
Where is the calibration key / button?
The default calibration key is the Scroll Lock key on a computer keyboard. The default way to start a calibration is to press the scroll-lock key 6 times. In addition, on some models, a hardware button is provided that can be used to start the calibration procedure with one press.
How do I turn the beeping sound off?
In USB Config, go to the General tab and set the buzzer time to zero.
How do I disable right mouse click?
For some applications, such as kiosks, it may be necessary to disable the right-click option so that users cannot access operating system functions.
To disable the right-click option, go to the Mouse tab in USB Config and set Right Click Delay to zero.
