Functions relating to data input
Input by touch switches
Data can be input by simply touching touch switches displayed on the screen.
The possible functions of touch switches include sending data to the host and changing the screen display.
Pop-up window function

In addition to fixed character and graphic displays, control keys and character keys created as touch switches can also be set
inside the window. A maximum of three windows can be displayed simultaneously

Numeral/character string setting function
Numeric keys and character keys can be assigned to touch switches so that numeric values and character strings can be input at
the operation site.
The input data is written to numeral/character string memory tables and also sent to the host. It is also possible to disable input by
control from the host.
Input from a bar code reader
Data read with a bar code reader can be input to a character string input field.
Functions relating to communication
Communications with the host
The NT31/NT31C can communicate with the host by four methods: host link, NT link
(1:1), and NT link (1:N) and Memory link. Data can be read from the host, and data
input by means of touch switches and numeral/character string settings can be sent to
the host. It is also possible to connect with other model PCs.
Functions relating to the system

System settings and maintenance can be performed by selecting from system menus displayed on the screen.
Creation of screen data
Screen data created using the Support Tool at a personal computer can be transferred and stored in the built-in screen data
memory.
