Home Serial Data Communications Isolators and Repeaters RS-232/422/485

Isolators and Repeaters RS-232/422/485

RS-232 boosters from B&B Electronics 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.
