Serial RS232 to RS422 Converters

   Commercial vs Industrial ?
There are no quality differences between the two.  All of our converters come with a 5 year warranty and are made to last. The only difference is the operating temperature range. Industrial typically is from -40°F to 185°F as compared to Commercial which typically is from -5°F to 140°F.   For most applications, industrial converters are not necessary and especially for indoor usage, commercial converters provides the best value.
