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 data
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.
