A-3-3 Converting the Built-in RS-232C Port to
RS-422A/485
• Four-wire Connections
Use one of the following Conversion Units to convert a built-in RS-232C port to an RS-422A port for a
CP1E N/NA-type CPU Unit.
• CJ1W-CIF11 RS-422A Conversion Unit
Maximum distance: 50 m, convertible to RS-422A or RS-485.
• NT-AL001 RS-232C/RS-422A Conversion Unit:
Maximum distance: 500 m, convertible to RS-422A only.
Note CJ1W-CIF11 cannot be connected to the built-in RS-232C port of the CP1E NS(1)-type CPU Unit.
The CJ1W-CIF11 RS-422A Conversion Unit is used to convert an RS-232C port to RS-422A/485.
It is directly connected to the built-in RS-232C port of the CP1E N/NA-type CPU Unit.
The Conversion Unit is not insulated, so the maximum distance for RS-422A/485 is 50 m.
Note CJ1W-CIF11 cannot be connected to the built-in RS-232C port of the CP1E NS(1)-type CPU Unit.
