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. The RS-422/485 repeater simply amplifies, or boosts, existing RS-422/485 signals to enable them to cover longer distances. It extends the communication distance by 1200m (4,000 ft.) or increases the maximum number of connected nodes by 32.

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.
