6-6 Communications Settings
 
● Interface Setting (NS5 Only) 
A setting in the System Menu for the NS5 enables switching serial port B between using the 
expansion interface connector and the serial port B interface connector. Communications will 
not be possible with the CX-Designer through the serial port B connector if the expansion in-
terface is selected. 
The use of the expansion interface is for future expansion and cannot yet be used. Always 
use the serial port B connector. (The default setting is Disable.)
