Composition of the Screen
The NT20 screen is composed of horizontal 256 dots x vertical 128 dots.
Each dot is set by the combination of the X (horizontal) and Y (vertical) coordi-
nates. The origin of coordinates (0, 0) is set at the top left corner of the
screen.
Screen Management
The screens displayed on the NT20 are managed by the screen numbers.
When using the NT20, up to 495 screens can be created and screen numbers
in the ranges 1 to 250 and 256 to 500 can be used (numbers 251 to 255 are
reserved for system use).
The display screens can be switched or the start-up screen can be set by des-
ignating the screen number from the Host.
Special Screen Number
Screen number “0” is reserved for the system as the no-display screen. Select
this to display nothing on the NT20 screen.
