Touchscreen

Standard Calibration

When you click this button, arrows

 

appear pointing to red squares. Use your

 

finger or stylus to touch the red squares in

 

sequence. After you touch the fifth red

 

square, calibration is complete. To skip,

 

press <Esc>.

Note To access the Advanced Calibration option, go to the Tools tab and select Advanced Calibration.

Advanced Calibration

Advanced calibration uses 4, 9, 16, or

 

25 points to effectively calibrate the

 

linearity of aged touchscreens. Click

 

this button and touch the red squares in

 

sequence with a stylus. To skip, press

 

<Esc>.

Note The older the touchscreen, the more advanced calibration points you need for accurate calibration. Use a stylus during advanced calibration for greater accuracy.

Plot Calibration Data

When you select this function, a touch

 

panel linearity comparison graph appears

 

after you finish advanced calibration.

 

The blue lines show linearity before

 

calibration, and black lines show linearity

 

after calibration.

Multiple Monitors

The Multiple Monitors function supports two to six touchscreen displays for one system. Each monitor requires its own PenMount touchscreen control board, installed inside the display or in a central unit. You must connect the control boards to the computer COM ports via the RS232 interface. Driver installation procedures are the same as for a single monitor. Multiple Monitors supports the following modes:

•Windows Extend Monitor function

•Matrox DualHead multiscreen function

•nVidia nView function

Note The Multiple Monitors function is for multiple displays only. Do not use this function with only one touchscreen display.
