ABSTRACT:
A method for interfacing two remote electronic units uses four lines and a handshaking routine including the steps of: causing the first unit to simultaneously transmit a strobe signal on one of the four lines and a signal representing one bit of the information to be communicated on a second of the four lines, sending the two signals continuously until acknowledged by the second unit; causing the second unit, when it receives these signals, simultaneously to transmit a strobe signal on a third line and a data signal, which may or may not be the same as that on the second line, on the fourth line, the third and fourth signals being transmitted continuously until their receipt is acknowledged; terminating transmission of the first and second signals when the first unit receives the third and fourth signals; and terminating the transmission of the third and fourth signals when the second unit determines that the first and second signals are no longer being transmitted. This routine is used for transmission of each bit of information to be communicated. If desired, a fifth line may be provided to carry a signal by means of which the first unit can reset the second unit so that transmission of the communication can be reinitiated in the event of difficulties.
