Glossary
Accuracy
The similarity of a distance measured by the tablet with the actual distance. When we specify that the accuracy
of a tablet is ± .010 inches, we mean that every point in the drawing area is within .010 inches of where it should
be.
ASCII
Abbreviation for American Standard Code for Information Interchange.
Baud rate
The rate of speed that data flows between a host computer and the digitizer. It is the number of bits transmitted
per second. The lower the baud rate, the slower the speed.
Bit
The basic unit of information in the binary system—either 0 or 1.
Button
A switch on the cursor or pen used to input data.
Byte
A group of eight bits that acts as a single unit of information.
Coordinate pair
A pair of numbers representing a unique point on the digitizer surface, usually the distance across and up from
the tablet origin.
CR
The ASCII carriage return character usually added to the end of the X,Y coordinate pairs sent by the tablet
(ASCII formats).
Cursor
1) A pointing tool used to select specific points on the tablet surface. 2) A symbol displayed on the screen
marking where the next action will take effect or where the next character typed from the keyboard will appear.
Data bits
Each transmission contains 7 or 8 data bits.
Data rate
The number of coordinate pairs (X,Y) the tablet sends to the computer per second.
Default
A value, action or setting that a computer system assumes unless the user gives an explicit instruction to the
contrary.
Drawing area
The area on the tablet surface intended for digitizing.
Format
The form in which data is sent from the tablet. The DrawingBoard III tablet can output 32 different formats.
Frequency
The number of waves that pass a fixed point in one second.
Height
See Proximity.
