3-3 Connecting the NT Support Tool
In order to install the system program in the NT21, or to transmit screen data
created
with the NT Support T
ool to the NT21, the NT21 must be connected to a
personal computer with an RS-232C cable.
The
NT21 connects with
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 NT21 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.
Serial
port A
(RS-232C, 9-pin)
Communication Conditions
The
communication conditions are automatically set when the system installer
and NT Support Tool are started.
