3-2 Connecting to the Support Tool
In order to install the system program in the NT31/NT31C, or to transmit
screen data created with the Support Tool to the NT31/NT31C, the NT31/
NT31C must be connected to a personal computer with an RS-232C cable.
The NT31/NT31C connects the RS-232C cable from a personal computer at
serial port A. When the host is connected at serial port B, the connection with
the host can be maintained as it is while the NT31/NT31C is connected to the
RS-232C cable from a personal computer.
However, when a bar code reader is being used, it must be disconnected, so
that the RS-232C cable can be connected, since they both use serial port A.
Communications Conditions
The communications conditions are automatically set when the system
installer and Support Tool are started.
