Abstract
An interconnect device permits use of 150 ohm twisted pair transmission lines to interconnect computers designed for use with 75 ohm coaxial cable. The device includes a pair of toroidal transformers mounted in an aluminum housing and separated by a Faraday shield. The primary winding of each transformer is connected to a separate coaxial connector. The second winding of each transformer is connected over a separate a twisted conductor pair to one terminal of a balanced data connector assembly.
