Writing Screen Data to the PT Using Automatic Transmission (Memory Unit to PT)

1.Check that the power supply to the NT631/NT631C is OFF, then set the DIP switches of the Memory Unit as follows after installing Memory Unit to NT631/NT631C.

SW1	SW2	SW2-4 ON: System/Screen transmitted simultaneously
		OFF: System/Screen not transmitted simultaneously

SW2-3 ON: Bank 1

OFF: Bank 0

SW1-4 ON: System program

OFF: Screen data

It is not strictly necessary to set SW2-1 to OFF (to disable writing to the PT), but it is recommended to do so to avoid loss of data in the event of operating errors.

•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, writes the system program into bank 0, and the screen data into bank 1 at all times.

2.Switch the NT631/NT631C power ON.

The screen data is automatically written into the Memory Unit. The screen data in the NT631/NT631C is preserved.

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 the data writing status is displayed by the means of the number of bytes and blocks (1 bank = 16 block = 1024k byte).

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 NT631/NT631C power OFF, remove the Memory Unit.

To operate NT631/NT631C continuously, switch the NT631/NT631C pow- er back ON.

In this mode, the system program or screen data in the Memory Unit is forcibly written to NT631/NT631C irrespective of the setting status of the NT631/ NT631C.

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 NT631/NT631C, this mode becomes convenient.
