RS-422/485 Repeaters
RS-422/RS-485 repeaters overcome the limitations of standard serial ports by using differential voltage lines for data and control signals.
RS-232/422/485 Converters
Serial media converters provide conversion between serial networks and other media.
RS-232/422/485 to Fiber Optic Converters
Fiber optic converter is used as an RS-232/422/485 point-to-point or point-to-multipoint connection for transmitting and converting full/half-duplex signals within a fiber optics environment.
