In this mode, the system program or screen data in the memory unit is forcibly
written to NT31/NT31C irrespective of the setting status of the NT31/NT31C.
Since data transmission by this method is faster than when the 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 NT31/NT31C, this mode becomes
convenient.
Reference: When data is written to the NT31/NT31C, the data that has been stored up until
that point is lost. When the system program is changed, the operation of
NT31/NT31C also changes.
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 memory unit to NT31/NT31C.
SW1
SW2-4 ON: System/Screen transmitted simultaneously
OFF: System/Screen not transmitted simultaneously
SW2
SW1-4 ON: System program
OFF: Screen data
SW2-3 ON: Bank 1
OFF: Bank 0
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.
Reference:
S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disables
the setting of SW1-4.
S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disables
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 combinations.
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.
S When writing the system program into the NT31/NT31C, the type of system
program inside memory unit and the type of PT unit must be corresponding.
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.
