!
If you are using WINtelligent LINX software with PLC-500 A.I., we recommend that
you run PLC-500 A.I. in a sizable window (NOT full screen). The default settings
under Windows for a full screen DOS box will not allow enough CPU time for LINX
to run properly in the background.
To switch between full screen and window display mode, press [Alt-Enter]. To set
the size of the window display, select Fonts … from the File menu, and pick a font
size.
2. Click the Advanced… button and set the following options.
