14.6 Beeper Acknowledgement
The EXLW/XLW PRIME contains an internal beeper that provides an audible acknowledgment
when an operator touches a graphic object that accepts touch input. When the graphic object
is enabled, a short 5ms tone is emitted. When the graphic object is disabled, a longer 100ms
tone is emitted to enounce that graphical object is not currently accepting the touch input.
If beep acknowledgement is not desired, the beeper function can be disabled from the System
Menu.
14.7 Touch (Slip) Sensitivity
Touch
slip
sensitivity is preset to meet most applications; however, adjustment is available to
reduce the sensitivity for touch release. That is, once a graphical object (button) is touched and
held by a finger, the default touch
slip
sensitivity allows for a slight
slip
of the finger on the
graphical object before the EXLW/XLW PRIME assumes touch has been released (equates to
approximately a quarter inch of movement with a stylus).
In some applications (such as jog buttons) where the operator is pushing a button for a period
of time, the amount of
slip
while holding a button pressed may exceed the default sensitivity.
To increase the amount of tolerable
slip
and prevent false releases of the button,
the
EXLW/XLW PRIME allows adjustment of the allowable
slide
up to 5x the default value.
To enable the touch (slip) sensitivity, first an OCS data register must be allocated through the
Graphics editor Configuration menu for Display Settings. Once a Touch Sensitivity register is
assigned, that register may be modified [range = 1(Low) to 5 (High)] to the desired slide amount.
If a value outside the valid range is entered in the touch sensitivity register, it is ignored, and
the last valid value is used.
