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
This is the easiest connection method. OMRON cables with connectors can be used, de-
pending on the host being connected.
PT
• A 1:1 Connection using RS-422A and an NS-AL002 or NT-AL001 RS-232C/RS-422A Con-
verter
This connection method allows an extended communications distance of up to 500 m.
PT
*1: The maximum transmission distance is 50 m when using the CJ1W-CIF11.
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.
PT
Note: Each port allows 1:N connection. With the NS-AL002, NT-AL001, or CJ1W-CIF11, connect ei-
• RS-422A Connection (NS15 Only)
If the RS-232C/RS-422A selector is used to select RS-422A, RS-422A
communications can be performed on serial port B.
