Start of Communication with the Host

Operation Start

Self diagnosis — including a check on the internal memory of the NT31/NT31C and a system program check — and the internal processing required for startup, are performed.

If an error occurs during initial processing, an error screen is displayed.

If there is an error in the system program, the system program must be re- installed. For details on the installation procedure, refer to 6-5 Operations in the System Installer Mode (page 150).

Check if a memory unit is installed. If a memory unit is installed, processing (screen data and system program reading/writing) is executed in accordance with its DIP switch settings (pages 39 and 47).

If there is an error in the screen data, an error screen is displayed. Pressing the OK touch switch on the error screen will return the display to that immediately before the error occurred. It is also possible to display the System Menu from the error screen by pressing two of the four corners of the touch panel simultaneous- ly. If there is an error in the system program, the main menu of the system install- er mode is displayed. If this is the case, reinstall the proper system program.

Initialize the memory or change the settings as required.

Communication with the host starts in accordance with the communication method set in the system memory of the NT31/NT31C. During the interval until communication is established, the system initialization screen (screen No. 9000) is displayed.

For details, refer to 6-8 Starting Operation (page 168).

If the system initialization screen remains on, display the System Menu by pressing two of the four corners of the touch panel simultaneously, and check the settings for the communication conditions for communication with the host.

The RUN mode is established, and operation starts in accordance with the screen data in the NT31/NT31C.

When changing the settings or checking the statuses, perform the appropriate operation by displaying the System Menu. For details on displaying the System Menu, refer to 6-3-3 Operations with the System Menu (page 138).
