Using a Memory Unit Section 2-5
Reference:
• Setting SW2-4 to ON (System/Screen transmitted simultaneously) dis-
ables the setting of SW1-4.
• Setting SW2-4 to ON (System/Screen transmitted simultaneously) dis-
ables the setting of SW2-3. In this case, the data transmission becomes
possible only if the data inside Memory Unit is in either of following combi-
nations.
Bank 0: system program, Bank 1: other than system program
Bank 0: other than system program, Bank 1: system program
If the combination is not as listed above, a data transmitting error occurs.
• When writing the system program into the NT20, the type of system pro-
gram inside Memory Unit and the PT model must correspond.
2. Turn the NT20 power ON.
The screen data is automatically written into the PT.
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 data writing status is displayed by the
means of the number of bytes and blocks (1 bank = 16 block = 1024k byte).
The 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.
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 NT20. Transmission can be
executed while checking the settings.
Reference:
When data is written to the NT20 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 NT20 power is OFF, then set the DIP switches on the Mem-
ory 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 Unit from which the
data is to be read.
2. Turn the NT20 power ON.
Display language select screen appears.
