Advantech's Serial Media Converter and Repeaters provide conversion between serial networks and other media. Our Serial Converters can transparently convert RS-232 signals to RS-422/485 signals, as well as wireless and fiber optic signals.

Serial Isolators & Repeaters

RS-232 boosters double the range of your RS-232 data signal. Repeaters may be daisy-chained for extra range. Many CE computers, laptops, and some desktops ship with low-power ports that are unable to drive port-powered devices or full-length RS-232 cabling. RS-232 signal boosters amplify these weak signals up to the RS-232 standard.
