Connection Methods
This section describes the methods for connecting the host to serial port A or B of the PT us-
ing RS-232C or RS-422A communications. The connection methods are as follows:
• Direct Connection using RS-232C
• A 1:1 Connection using RS-422A and an NS-AL002 RS-232C/RS-422A Converter
The NS-series PTs have two serial ports that can be used simultaneously. Therefore, two
hosts can be connected at the same time. Any combination of devices can be connected to
the PT.
Note: Each port allows 1:N connection. The NS-AL002 Converter can be connected to one serial port
• RS-422A Connection (NS15 Only)
• Supported RS-232C Host Units
Some models and series of OMRON PLCs have a built-in 1:1 NT Link function. Some PLCs
can also be connected in a 1:1 NT Link by adding a Serial Communications Board or Com-
munications Board.
When connecting the PT to a PLC, check the series and model of the PLC and the model of
If the RS-232C/RS-422A selector is used to select RS-422A, RS-422A
communications can be performed on serial port B.
Precautions
for Safe Use
This is the easiest connection method. OMRON cables with connectors can be used, de-
pending on the host being connected.
This connection method allows an extended communications distance of up to 500 m.
