    By using the RS-232C/RS422A Link Adapter (NT-AL001), RS-232C can be converted to RS-422A, and commu- nications over a distance of up to 500 m is possible. Connection is possible using the NT30/NT30C’s RS-232C connector or using the NT30/NT30’s RS-422A terminal block. The methods differ in the way shown below.
