Registering the Screen Data
Section 3-6
Note
When screen data is transmitted to an NT20, it is written into a free area of the
memory without overwriting the existing data. This means that if data trans-
mission 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 impossi-
ble. If this happens, transmit the data in file units to reorganize the contents of
the NT20 memory.
Transmitting the Screen Data from the Support Tool
To transmit the screen data from the Support Tool to the NT20, connect the
NT20 to the computer on which the Support Tool is being used, and follow the
procedure below.
Note
When the screen data transmission is attempted, the screen data memory in
the NT20 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 NT20-ST121-E/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 (per-
sonal computer) before attempting screen data transmission.
