Operating Modes
There are two types of operating modes available in the operating terminals, the
standard mode of operation and the transparent mode of operation.
Terminals operating in the transparent mode represent full-size ANSI-terminals.
Each key generates a press and release code, which will be transmitted via the
interface SER1 in the form of an ASCII character. The displays and the key LEDs
are controlled via ESC sequences. The number of character sets and character
attributes varies with the type of display. For a detailed description please refer to
the chapter ‘Transparent Mode’.
In the standard mode of operation, the entire operating system is integrated in the
terminal. The standardized operating concept completely frees the connected con-
troller from any operator guidance tasks as well as data display. In standard mode, a
decoding of the keys or selection of masks from within the controller is not required.
3.1
Setting the Operating Mode
The operating mode can be set by means of the User-Mode-Switch. The terminals
are factory-set to the standard mode of operation.
The user-mode switch is accessible at the side of the terminal NT4S-SF122B-E
and at the rear side of all other operating terminals.
