Digitizer Specifications

The Stylistic 2300 pen tablet digitizer consists of the pen, an electromagnetic sensor grid, and supporting
controller circuitry. The sensor grid is built into the pen tablet behind the display screen and receives an
electromagnetic signal from the pen. The signal indicates the pen location relative to the sensor grid. The
pen signal is received by the sensor grid when the pen is within a minimum proximity of approximately
10 mm from the screen surface. (This allows the pen to control the cursor position without touching the
screen surface.) Switch information on the pen is determined by the characteristics of the signal
transmitted from the pen. Digitizer specifications are given in Table 5-4.
Note: The pen tip switch must be pressed to turn the pen on (pen transmitting). The pen turns off
automatically after a period of time (between 1.5 to 4.5 minutes) with no activity.
