RS-232/422/485 Converters


The serial media converters provide conversion between serial networks and other media. They can transparently convert RS-232 signals to RS-422/485 signals, as well as convert RS-422/485 to RS-232 signals without changing the PC's hardware or software. The converter lets you easily build an industrial grade, long distance communication system with standard PC hardware.
