NX-series Communications Interface Units User’s Manual (W540)
To make the maximum of 20 patterns, purchase two sets of NX-AUX02 Pins. (One set for 10 Units.)
Precautions for Correct Use
• OMRON uses the holes other than No. 1 to 6 in the figure on the previous page. If you insert
a Coding Pin into one of the holes used by OMRON on the terminal block side, this makes it
impossible to mount the terminal block on a Unit.
• Do not use Coding Pins that have been attached and removed.
Inserting the Coding Pins
1 Hold the pins by the runner and insert a pin into one of the incorrect attachment prevention
holes on the terminal block or on the Unit.
2 Rotate the runner to break off the Coding Pins.
