Connector Pin Arrangement
Note:
Connect NT20S-ST128 with an RS-232C Interface Unit installed to the host com-
puter with an RS-232C cable.
RS-232C connection allows a single NT20S to be connected to the host.
A computer or other control device with a built-in RS-232C interface is a suitable
host for connection to the NT20S.
Set the host communication conditions according to the following table.
Set the same communication conditions at the NT20S and Host.
Refer to the appropriate instruction manuals for the method of setting the Host
communication conditions.
Set to the maximum baud rate supported by both the NT20S and Host.
The communication condition settings of the NT20S-ST128 are set with the
RS-232C communication conditions memory switches. For details, refer to “Set-
ting RS-232C Communication Conditions” on page 82.
The RS-232C connection between the NT20S and Host is described below.
The connector specification is described below.
Electrical characteristics: Conforms to EIA RS-232C specifications.
Signal direction: Signal input and output are relative to the host computer.
