The DrawingBoard V
Output format
The system of characters used by the DrawingBoard IV tablet for output-
ting data.
Parity
A type of error detection where a bit is inserted into every character the
digitizer transmits. The status of the parity bit confirms that the data was
not altered during transmission.
Pen tilt correction
An option that allows for tilt correction in the pressure pen.
Pen tilt data
An option that allows output of tilt data in the pressure pen.
Point mode
The digitizer transmits one coordinate data point when a cursor button or
the pen tip is depressed.
Pressure pen data
Data output from the pressure pen.
Prompt mode
The digitizer transmits one coordinate pair each time the computer sends
a prompt character to the unit. Prompting can operate with any mode
except Mouse mode.
Proximity
The greatest distance above the Active Area that the transducer can be
raised and still be sensed by the tablet.
RAM
Abbreviation for Random Access Memory, a specific type of memory
used by the computer.
Resolution
The distance increment that the tablet outputs in lines/inch or lines/mm.
ROM
Abbreviation for Read Only Memory, a specific type of memory used by
the computer.
Run mode
The digitizer transmits coordinate data points continuously, regardless of
the status of the cursor buttons or the pen tip. This mode is also called
Stream
by some manufacturers.
Serial transmission
Data transmission protocol where each bit of the data character is sent
one at a time over a single circuit. This system saves on transmission
circuitry, but is usually slower than parallel transmission.
