Reference: When data is written to the NT31/NT31C, the data that has been stored up until
that point is lost.
Method of Execution
Use the following procedure to write the screen data in the memory unit to the
NT31/NT31C by automatic transmission.
1, 2, 3... 1. Check that the NT31/NT31C power is OFF, then set the DIP switches on the
memory unit as follows after installing the memory unit in NT31/NT31C.
OFF
SW1
SW2-3 ON: Bank 1
OFF: Bank 0
SW2
OFF
1 1 2 2 3 3 4 4
It is not strictly necessary to set SW2-2 to OFF (to disable writing to the
memory unit), but it is recommended to do so to avoid loss of data in the
event of operating errors.
2. Switch the NT31/NT31C power ON.
The screen data is automatically written into the PT.
The messages Preparing, Transmitting, Verifying and Finished are dis-
played on the screen in accordance with the progress of data writing.
When messages Preparing, Transmitting, and Verifying are displayed, the
RUN LED flashes, and when the message Finished is displayed, the RUN
LED lights.
3. Switch the NT31/NT31C power OFF, and remove the memory unit.
To operate NT31/NT31C continuously, switch the NT31/NT31C power back
ON.
In this method, the direction of transmission and area of the memory unit used
are set by touch switch operations at the NT31/NT31C. Transmission can be
executed while checking the settings.
Reference: When data is written to the NT31/NT31C or memory unit, the data that has been
stored up until that point is lost.
Method of Execution
Use the following procedure to read and write screen data using manual trans-
mission.
1, 2, 3... 1. Check that the NT31/NT31C power is OFF, then set the DIP switches on the
memory unit as follows.
