GENERAL QUESTIONS

12) ARE ALL PORT-POWERED CONVERTERS COMPATIBLE WITH NEW COMPUTERS?

Answer: Yes, our converters work well with newer computers, which normally come with lower voltage RS232 COM ports (typically +/-6VDC compared to the +/-15VDC used by older computers). If you are unsure whether your computer will port-power the converter properly, we recommend using the CON-422-PIE or CON-485-PIE which may be optionally used with an external power source, or use our one of our externally powered converters.
