Interface circuit for transmitting and receiving data |
摘要 |
An interface circuit for transmitting and receiving binary data as between a plurality of transmitting/receiving units such as for example electronic typewritters which are connected together. The circuit is suitable for transmitting and receiving data and timing (clock) pulses on two different lines, at a frequency particular to the transmitting unit. The circuit is provided with a binary counter prior to the transmission of data, the clock line is sampled to establish if the line is free and thus ready to receive, or occupied.
