Signal conversion circuit for interconnecting coaxial cable and a twisted pair

摘要: In typical multi-terminal computer installations, each display terminal is connected to a controller by coaxial cable (commonly referred as coax) with concommitant limitation on the distance from that any can be placed, normally in range of few thousand feet. The disclosed invention eliminates need for direct connection between and terminals. form described, two interface units are utilized. first unit single cable. That second pair twisted wire, such telephone line. Connected many eight connections Using half duplex operation then address poll terminals transmit receive data. circuits great five If additional required, sets used.
