ABSTRACT:
A data communication system between computers comprises communication paths composed of m transmission lines between the computers. Data and data to be transferred is coded based on a coding table. Each code comprises a series or string of figures. Each figure has a numeric value not over the m-th power of 2. Also, those adjacent figures in each code string have necessarily different values. Coded data is transmitted figure by figure through m transmission lines. Since values of each figure in a code necessarily differ, a timing signal is not required.
