CR 1212 28
Relative Coordinates (Delta Mode)
The tablet defaults to an absolute coordinate system. This command changes it to a
relative coordinate system. Absolute coordinates are measured from the tablet’s origin (0,
0). Relative coordinates are measured relative to the last report location. (Refer to
Chapter 1 for details.)
In this operational mode, the active area origin is the lower left corner of the tablet.
Stylus/cursor movement up and to the right is positive. Movement down and to the left is
negative. (You can change the origin location to the upper left corner with the Origin
command. Stylus/cursor movement down to the right is positive; up and to the left is
negative.)
Reset (to Default Operating Characteristics)
Use Reset to return the CR 1212 to the default operating characteristics:
 Coordinate system: absolute
 Increment: 0, Increment Mode off
 Origin: lower left corner
 Report Mode: In the Bit Pad One configuration, the mode is Stream. In the
Bit Pad Two or CR configuration, the mode is Remote Request.
 Report Rate: 110 or 72 rps (reports per second) depending on hardware
configuration
 Resolution: 200 lpi
 Tablet Beep: enabled
If the stylus/cursor is out-of-prox when the tablet receives the Reset command, and if it is
still out-of-prox when the tablet issues a report, the X and Y coordinate values are zero.
