A unipolar pulse communication system exploits the fact that certain computer terminals will react only to information pulses of a specific polarity and remain passive to pulses of the reverse polarity. A device at one end of the system passes pulses unchanged, from a first station of a computer to a single cable at the output of the device. Pulses received from a second station of the computer pass through the same device but are inverted before being passed through to the same cable. At the other end of the cable, all pulses are passed unchanged to a third station, and all pulses are inverted and then passed through to a fourth station. As the third and fourth stations only react to information pulses of a specific polarity, the result of the device is to permit two stations of the computer to be connected to two remote stations using only a single interconnecting cable. The device at either end of the cable may be designed so as to permit the same device to be used at either end of the cable.
