The NT20S allows the transmission of data for specified screens. By selecting the
screen number of the screen to be transmitted using the support tool, it is possible
to transmit the required screen only to the NT20S (it is also possible to transmit
multiple screens in a batch).
When changes have also been made to the memory tables or direct connection
information, transmit the changed data to the NT20S too, for example by using
transmission in screen units.

When screen data transmission is in screen units, if there is data other than screen
data, for example memory table or direct access changes, transmit this data also.
memory without overwriting the existing data. This means that if data transmis-
sion in screen units is performed frequently, there will come a time when there is no
more free area in the memory and further transmission is impossible. If this hap-
pens, transmit the data in file units to reorganize the contents of the NT20S
memory.
To transmit the screen data from the support tool to the NT20S, connect the
NT20S to the computer on which the support tool is being used, and follow the pro-
cedure below.
NT20S is automatically initialized before new screen data is transmitted. It is not
necessary to initialize the screen data memory by using the menu before the
screen data transmission.
The NT20S-ST121-EV3/ST128 uses the same connector for screen data trans-
mission and connection to the Host. If this connector is currently connected to the
host, disconnect the cable from it and connect it to the support tool (personal com-
puter) before attempting screen data transmission.
