2500 Series 12
Operating Modes
The operating mode sets the conditions that must be satisfied before the tablet will
transmit position to the host. One or more modes may be active concurrently.
Prompt Mode
The host must transmit a prompt character to the tablet before a data point will be output.
The default prompt character is “?”. Prompting can operate in conjunction with any other
mode.
Relative Output Modes
A relative mode does not have a direct relationship between the tablet cursor position and
the screen cursor position. The movements of the screen cursor will duplicate the tablet
cursors’ movement’s right, left, up and down, but its exact position on the screen will
depend only on where it was when the cursor was activated.
Delta
The data output represents the change in the transducer’s position since the last point was
output rather than the absolute position of the transducer on the tablet. DELTA may be
used in conjunction with Line, Run, Point or Track.
Absolute Output Modes
Absolute modes have a direct relationship between the tablet’s active area and the screen
display. If the cursor is moved from the lower left to upper right on the tablet, the screen’s
cursor will move from the lower left of the screen to the upper right.
HALT
LINE
POINT
Tablet continues to accept commands, but no data will be
output until a new mode is selected.
Tablet outputs position data continuously while the stylus
tip or a cursor button is depressed. One additional point
is output when the stylus or button is released.
Tablet outputs one data point each time the stylus tip or
cursor button is depressed.
