z Application Example
Note The following cables can be used for this connection.
It is recommended that one of these cables be used to connect the RS-232C port on the Option Board
to the NT-AL001 RS-232C/RS-422 Conversion Unit.
z Wiring for the Recommended Cables (XW2Z-070T-1 or XW2Z-200T-1)
Note The hood (FG) is internally connected to the ground terminal (GR) on the CPU Unit.
Therefore, FG is grounded by grounding the ground terminal (GR) on the power supply termi-
nal block.
Precautions for Correct UsePrecautions for Correct Use
⢠The XW2Z-î
î
0T-1 Connecting Cables for the NT-AL001 Link Adapter uses special wiring for
the DS and RS signals.
Do not use these signals with other devices.
Connecting this cable to other devices can damage them.
⢠Always turn ON the terminating resistance if the node is at the end of the RS-422A/485 trans-
mission path.
