MM II 30
When updating to relative coordinates, the lower left corner of the tablet becomes the
active area origin. 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 and to the right is
positive; up and to the left is negative.)
Also, when the tablet is using relative coordinates, reports issued out-of-prox are zero.
Origin
Use the Origin command to define the location of the tablet’s origin (0, 0). It can be the
lower or upper left corner of the active area. The default is the lower left.
When the origin is in the upper left corner, Y coordinates are positive, not negative. This
departure from the standard Cartesian coordinate system is to aid in the compatibility
between the MM II and terminals with a screen origin in the upper left corner.
Reset (to Defaults)
Use
Reset
to run the Self-Test diagnostic function and returns the MM to the defaults:
Axis Update: 0, Axis Update Mode off
Coordinate system: absolute
Increment: 0, Increment Mode off
Origin: lower left corner
