Question
The NS-series Programmable Terminal is not equipped with an RS-422A port, so how can it communicate beyond the rated distance for RS-232C (15 m)?
Answer
Use an NS-AL002 RS-422/RS-232C Converter.
Just attach the NS-AL002 Converter to the RS-232C connector to use it as an RS-422A port. Use an NT-AL001 RS-232C/RS-422A Link Adapter to Convert serial communications at the Programmable Controller.
