A panel of 6-row x 12-column touch switches, each switch sized 1 x 1 cm, will
be displayed.
• Press a touch switch on the screen. If the touch switch is highlighted while
it is pressed, the touch switch is normally functioning.
• When the check is finished, press the EXIT touch switch. The I/O check
menu will be redisplayed.
If memory switch setting for the key press sound has been made for ON, the
key press sound will be made when a touch switch is pressed.
The status of touch switches pressed during an I/O check is not sent to the
host.
Execute a NT20-to-Support Tool communications check by the menu opera-
tion from the System Menu as described below.
The NT20-ST121-E/ST128 uses the same connector (Port A) for connection
to the Support Tool and connection to the Host. If this connector is currently
connected to the host, disconnect the cable from it and connect it to the Sup-
port Tool (personal computer) before attempting screen data transmission.
