Abstract:
An electric arrangement for transmitting digitally encoded information from a first electric device to a digital processor in a second electric device, comprising:a) an encoder located in the first electric device and containing the digitally encoded information, the encoder containing the digitally encoded information on at least one output terminal,b) a single communication line capable of conveying electric information signals representing the information between the electric devices,c) a decoder located in the second electric device, said decoder capable of decoding the information signals into information and supplying the information to the processor in the second device,d) a variable voltage generator located in the second device and connected to the communication line, said variable voltage generator capable of supplying a sequence of voltage levels to the communication line,e) a voltage dependent current generator located in the first device and connected to the at least one output terminal of the encoder and to the communication line, said current generator capable of outputting the information signals in the form of a sequence of current levels through the communication line, said sequence of current levels being dependent both on the voltage level as detected on the communication line and the digitally encoded information on the at least one output terminal of the connected encoder, andf) a current detector located in the second device and connected between the communication line and the decoder for conveying the information signals to the decoder.
