Use the following Cables to connect the RS-232C port on an Option Board to an NT-AL001 RS-
232C/RS-422A Link Adapter.
Wiring the Recommended Cable (XW2Z-070T-1/XW2Z-200T-1)
Note The shell (FG) is internally connected to the protective earth (GR) terminal on the CPU Unit. FG can thus be
connected by connecting the protective earth (GR) terminal on the Power Supply Unit.
Precautions for Correct UsePrecautions for Correct Use
•The XW2Z-@@0T-1 Cable is designed to connect the NT-AL001 and contains special wiring for
the DS and RS signals. Do not use this cable for any other application. Connecting this cable
to other devices can damage them.
• Always turn ON the terminating resistance on the ends of the RS-422A/485 line.
