Operations in the System Installer Mode
Section 6-5
6-5-2 Clearing/Installing the System Program
Use this function when the system program of the NT31/NT31C has been cor-
rupted, or when installing a new system program.
Reference - In order to install a system program, the system installer must also be installed
at the Support Tool. The system installer is an accessory with the Support Tool
(ZJ3AT1/ZJCAT1-EV2). When installing the Support Tool in a personal com-
puter, install the system installer also. For details on the method for installing
the system installer at the Support Tool side, and the operating procedure, refer
to the NT-series Support Tool Ver. 2.0 for Windows95 Operation Manual
(V045-E1).
- When the system program is cleared by mistake, it becomes impossible to use
the NT31/NT31C at all. Check that the system installer is installed at the Sup-
port Tool side before deleting the program. However, note that the registered
screen data and memory switch settings are retained.
- It becomes possible to install the system program inside the memory unit auto-
matically by installing the memory unit at startup (Refer to 3-5 “Using Memory
Unit (NT31/NT31C with V1)” page 46).
Clear/install the system program by following the menu operation from the System
Installer mode menu shown below.
Clearing the System Program
Select “Download System Program”.
Select “Yes ”.
The system program is cleared. During clear-
ance, the message “Erasing ...” is displayed.
S If “Return to Menu” is selected, the NT31/NT31C returns to the System Installer
mode menu without clearing the system program.
S If clearance fails, a screen asking whether you wish to try again is displayed.
On completion of system program clearance, the NT31/NT31C enters the standby
status for downloading of the system program.
