Using a Memory Unit Section 2-5
2. Turn the NT20 power ON.
The screen data is automatically written into the Memory Unit. The screen
data in the NT20 is preserved.
The messages Preparing, Transmitting, Verifying, and Finished are dis-
played on the screen according to the progress of data writing.
At the same time, the progress of the data writing status is displayed by the
means of the number of bytes and blocks (1 bank = 16 block = 1024k byte).
RUN Indicator 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. Turn the NT20 power OFF, remove the Memory Unit.
To operate NT20 continuously, turn the NT20 power back ON.
Writing Screen Data to the
PT Using Automatic
Transmission (Memory
Unit to PT) In this mode, the system program or screen data in the Memory Unit is forcibly
written to NT20 irrespective of the setting status of the NT20.
Since data transmission by this method is faster than when the NT Support
Tool or system installer is used, it can save a lot of time. When transmitting the
same system program or screen data to multiple NT20, this mode becomes
convenient.
Reference:
When data is written to the NT20, the data that has been stored up until that
point is lost. When the system program is changed, the operation of NT20
also changes.

Method of Execution
Use the following procedure to write the screen data in Memory Unit to the
NT20 by automatic transmission.
1,2,3... 1. Check that the NT20 power is OFF, then set the DIP switches on the Mem-
ory Unit as follows after installing Memory Unit to NT20.
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.
SW2-4 ON: System/Screen transmitted simultaneously
OFF: System/Screen not transmitted simultaneously
