Frequently Asked Questions

Question 24:  WILL THE CONVERTERS WORK WITH USB TO RS-232 ADAPTERS?

Answer:  Most of modern computers (especially Laptops) do NOT come with RS-232 COM ports, therefore USB to RS-232 Cables / Converters (which creates a Virtual COM port on the PC) are widely used. We have tested our converters with many kinds of USB to RS-232 Cables / Converters available in the market. There is no problem using our converters with USB to RS-232 Cables / Converters. However, if you found your USB/RS232 converters/cables do not work with our converters, please send us an email.
