Using a Memory Unit Section 3-5
If the combination is not as listed above, a data transmitting error occurs.
• When writing the system program into the NT31/NT31C, the type of sys-
tem program inside Memory Unit and the type of PT must correspond.
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.
At the same time, the progress of data writing status is displayed by the
means of the number of bytes and blocks (1 bank = 16 block = 1024k byte).
The RUN LED operates as follows according to the processing status.
Preparing: flashes at intervals of 1 second
Transmitting: flashes at intervals of 0.5 second
Verifying: flashes at intervals of 0.5 second
Finished: lights up
3. Switch the NT31/NT31C power OFF, remove the Memory Unit.
To operate NT31/NT31C continuously, switch the NT31/NT31C power
back ON.
Reading and Writing Data
by Manual Transmission
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 write screen data using manual transmission.
1,2,3... 1. Check that the NT31/NT31C power is OFF, then set the DIP switches on
the Memory Unit as follows.
In order to avoid loss of data in the event of operating errors, it is advisable
to set SW2-1 and SW2-2 so as to disable writing to the PT from which the
data is to be read.
2. Switch the NT31/NT31C power ON.
