Connecting to the Support Tool

1. In cases where there is a potential difference between the grounds of the
NT631/NT631C and the host, ground as shown in Fig. If there is some dis-
tance between the NT631/NT631C and host and grounding at a single
point is difficult, do not connect the functional ground terminal (
NT631/NT631C.
2. If the NT631/NT631C is installed in the same panel as equipment that gen-
erates noise, such as a motor or inverter, do not ground the functional
ground terminal (
NT631/
NT631C
Carry out grounding correctly in order to prevent operating errors due to
noise.
In order to install the system program in the NT631/NT631C, or to transmit
screen data created with the Support Tool to the NT631/NT631C, the NT631/
NT631C must be connected to a personal computer with an RS-232C cable.
The NT631/NT631C 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 NT631/NT631C 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.
