Serial Converters, Repeaters and Suppressors Serial Media Converter and Repeaters provide conversion between serial networks and other media. Our Serial Media Converter can transparently convert RS-232 signals to RS-422/485 signals, as well as wireless and fiber optic signals. Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range and networking capabilities. The RS-422/485 standards overcome these limitations by using differential voltage lines for data and control signals.
