ADP-1154 User Manual 38
Stream/Point Mode
Stream and point modes control the touch and drag function of the touch screen. The
point mode only allows “touch” interaction with the screen and does not allow the user to
drag objects. The point mode is useful for maintaining the location of screen icons such
on POS terminals. The stream mode allows a user to touch and drag icons and other
items around on the screen, similar to using a mouse.
Drawing Mode
Drawing mode is a utility that lets the user draw on the screen using a finger or stylus.
This allows the user to test the touch screen and touch controller to see if it is operational
or is mapped correctly. The drawing mode can display either the matrix address of points
touched or just show lines drawn. One of the PenMount driver’s strengths is a special
mathematical algorithm that minimizes the occurrence of noise and smooths the drawing
of lines.
Beep Sound
All of PenMount’s drivers support the beep sound function; however, some PC systems
may only offer a fixed buzzer sound.
Beep Sound Adjustable
Software drivers for Windows systems let the user adjust the frequency and length of the
beep sound. The drivers let the user adjust the desired touch screen sound, as well as
turn the sound off.
Wake Up Function
The Wake Up function lets the user touch the screen and wake the system up from
‘suspend’ mode.
Point Calibration Data
The Plot Calibration Data function displays the touch screen linearity map, which is
available if the PenMount driver provides an Advance Calibration function when touch
screens age their touch linearity declines. This non-linearity is apparent when the
touched point on the touch screen is not the same as the point on the display. The plot
calibration data function shows the linearity status of the touch screen. This is only a
support function for the user. The exact linearity of a touch screen requires a linearity
test machine.
