Abstract: In a remote control system wherein control commands are sent as telegrams, each containing a fixed number of binary bits, transmission of each telegram is required to span a time interval divisible into equal periods, the number of such periods being equal to the number of bits in a telegram, and each bit pulse being required to persist for a predetermined portion of the duration of its period. Preferably the last pulse of each telegram has a longer duration than the others. The long last pulse is utilized for telegram framing as well as for authenticating received telegrams.
