Installation guide

Table E–1 can help you determine how to set up the entries for the tablet
in the /usr/var/X11/Xserver.conf file.
Table E–1: CalComp DrawingBoard III Tablet Configuration Options and
Values
Option Description
device The port (tty) to which the device is connected. The default is
tty00.
mode This should be set to 1 for absolute motion.
tabletWidth Width of the active tablet area in inches, not the physical size.
The default is 12.
tabletHeight Height of the active tablet area in inches, not the physical size.
The default is 12.
numbtns Number of buttons on the puck or pen. The maximum number
is 16 and the default is 16.
corePointer 0 indicates a native tablet mode (no system mouse). 1 indicates
emulate core pointer (the mouse and tablet are both core pointer
devices. The default is 1 (emulate core pointer).
mouseScale 1 to 50 scaling factor in relative mode. Determines the speed of
the cursor; the higher the number, the slower the cursor moves.
The default is 8.
resolution 1 to 2540 lines per inch (lpi). The default is 1000.
Xincrement How much the X axis must be incremented to cause the tablet
to send new coordinates to the Xserver. The range is 0 to 65536.
The default is 1.
Yincrement How much the Y axis must be incremented to cause the tablet
to send new coordinates to the Xserver. The range is 0 to 65536.
The default is 1.
The device option is required and specifies which tty device should be
associated with the tablet. By default, the installation software assigns the
CalComp DrawingBoard III tablet to tty00, which you may want to change
if that tty is already allocated. For information on how to determine which
serial port your tablet is connected to, see the hardware documentation
that was shipped with your processor.
Note that when the stylus or puck is moved as far as the minimum
Xincrement or Yincrement value, the value of the corresponding axis is
updated. For example, if the Xincrement value is set to 10 and the tablet is
moved 10 units along the X axis, the value of the Y axis will also be
updated simultaneously with the X axis, even if the Yincrement value has
not been reached. Keep this in mind when setting the Xincrement and
Yincrement options.
