Operating a NextWindow 2700 Touch Overlay with an Apple Mac Computer

Apple Mac Mode

To operate with an Apple Mac computer, the 2700 Touch Overlay must be in Apple Mac mode. This is achieved by running NextWindow’s CalibrateNWTS utility program, which also allows you to calibrate the touch screen. You only need to run this program once only—when first connecting to an Apple Mac.

To Enable Apple Mac Mode:

With the USB cable connected from the touch overlay to the computer, run the utility program, CalibrateNWTS, which is available on the CD, or can be downloaded from NextWindow’s website.

After a few seconds, the utility automatically puts the touch screen into Apple Mac mode. You then should calibrate the touch overlay before using it.

Calibrating the Touch Overlay

To initiate the calibration procedure on a NextWindow 2700 touch overlay connected to an Apple Mac computer, you can use the CalibrateNWTS program, or you can press the hardware Calibration button, which is recessed in a hole on the side of the unit.

Calibration Procedure

With a clear desktop on the computer:

1.	Click the [Calibrate] button in the CalibrateNWTS program.
	(Or gently press the calibration button through the hole on the side of the unit until you hear a beep.)
	The mouse pointer automatically moves to a position at the top left of the screen.
2.	Touch and hold your finger on the screen at that position until you hear a long beep.
3.	The pointer moves to three further positions in sequence—top right, bottom right and bottom left. Touch each point in turn until you hear the beep.

This completes the calibration procedure.

Test the calibration by moving your finger around the screen checking that the mouse pointer follows it closely. If the calibration is not satisfactory, you can re-calibrate.

The touch screen is now ready for use.
