Telebyte’s Multiplexers employ techniques that allow a number of simultaneous transmissions over a single circuit. Many can be used to interface between two signal types such as RS-232 and RS-422. Telebyte Multiplexers include RS-232 to RS-422 full-duplex interface converters, RS-232 to current-loop converters, V.35 line driver eliminators and more. Features include four and eight-port for copper, fiber optics and port sharing.
