    摘要: PURPOSE:To transmit data of H, L binary values at the same time in two directions on a common transmission line by utilizing the presence of a voltage on the transmission line and the presence of a current having a directivity at the presence of voltage through combination. CONSTITUTION:Since transistors (TRs) Q10-Q12 and Q20-Q22 are turned off when transmission data T1, T2 are both logical 0, V, I, D1, D2 are all logical 0, and reception data R1, R2 are logical 0 by pull-down resistors R13, R23. When the transmission data T1 is loginal 1 and the T2 is loginal 0, since the TRQ10 is turned on, the current detection output D1 is loginal 1. Since the TRQ21 is turned on, a current flows in the path of the resistor R21, a transmission line 34 is not grounded directly even at T2=0 but keeps logical 1. The signal with the level 1 becomes the recpetion data R2 via the emitter and collector of the TRQ21. On the other hand, since D1=1 is established in the device 1, the TRQ12 is turned off and since T1=1, V=1 are established, the Q11 is turned off and then the reception data R1 is logical 0.

    摘要: PURPOSE:To obtain a device which requires only one connection line and has a shorter reaction time than a device which employs a polling system with one connection line by using two different start bit patterns for transmission and reception between two devices. CONSTITUTION:When a transmitter/receiver 1 performs transmission to a transmitter/receiver 2, a start bit pattern is sent at first and a serial signal is then transmitted. The device 2 after recognizing the start bit pattern receives the serial signal. Transmission from the device 2 to the device 1 is the same. In this case, 1 is the start bit pattern from the device 1 to the device 2 and 5 is the start bit pattern from the device 2 to the device 1; when the transmission from the device 1 to the device 2 and the transmission from the device 2 to the device 1 coincide with each other, the 1st bits of the start bits patterns are both at a level LOW, but the 2nd bit on the side of the device 1 is at LOW regardless of transmission of HIGH, so it is found that the transmission on the side of the device 2 is carried out. Then, the side 1 is placed in reception mode to confirm that the next one bit from the side 2 is at HIGH, and the serial signal succeeding the next bit is received. Transmission is started after the reception is completed.

    摘要: PURPOSE:To improve the utilizing efficiency of a transmission circuit, by transmitting outgoing and incoming signals with different potential levels to attain bidirectional data transmission via a pair of transmission lines. CONSTITUTION:When the outgoing signal to each terminal is transmitted to a transmission transistor(TR) 6 at the center side 1, the TR6 is driven to convert a signal into the outgoing signal having a high power supply voltage VCCT level, and the signal is transmitted to a signal line 3. Since the voltage VCCT exceeds the Zener voltage of a Zener diode 9 at a terminal side 5, a current corresponding to the outgoing signal flows to the Zener diode 9, a resistor 10, and an LED11, and the outgoing signal is converted into a receiving signal by a photocoupler 8. When an incoming signal is given to a transmission TR14, the TR14 applies the incoming signal of the VCCR power supply voltage level to the signal line 3. Then, the incoming signal is converted into the receiving signal by a photocoupler 15. Since the potential of the signal line 3 in this case goes to the VCCR or below lower than the Zener voltage of the Zener diode 9, no outgoing signal is received by the photocoupler 8.

    摘要: PURPOSE:To attain an inexpensive transmission line, by supplying power to a terminal side and transmitting an outgoing signal of a voltage polarity and an incoming signal of opposite polarity via a pair of transmission lines. CONSTITUTION:When no signal is transmitted, a timer 3 at the center is reset, an output terminal TO is at H level, a positive voltage is applied from a positive voltage power supply to a signal line 9, and a power receiving circuit 29 at each terminal is charged. A P-S converter 2 receives outgoing data and sets it, and a serial signal is outputted from a output terminal SO1 with an indicating signal. A timer 3 is set in this case and the power supply is stopped. The voltage of a BUSY signal from the converter 2 to a receiving means 17 is dropped to inhibit the receiving of the outgoing data, and an output of the terminal SO1 drives a transmitting means 4. A signal line 9 in this case is a negative. Thus, an outgoing signal current flows only to a resistor 13, a receiving means 11 and a diode 12 at the terminal side, and the outgoing signal is outputted from a signal circuit 14. When the outgoing signal is finished for transmission, the BUSY signal goes to L, a receiving control means 22 is turned off and a positive potential is given to the signal line 9.
