The computer Z RS-23 serial interface current loop circuit diagram

Published:2011/3/30 22:09:00 Author:Ecco | Keyword: serial interface, current loop

This circuitry is used for the joggle between computer Z RS-23 serial connecting current ring and current ring circuitry, it can transform the voltage semaphore of transmission into the current semaphore with 20 mA, the biggest speed can reach 1200 bits. Light-coupled device IC3, T1 make up receiving port connecting interface circuit, T2, T3 constitute transmitting terminal interface circuit. When the source is 12V, T2, T3 deliver energy, the current will be sent to IC1 by the circuitry from T2, and pass light-emitted diode of IC1, return to the transmitting terminal again, and the current is about 20mA. When the source is -12V, T2, T3 wil be cut off, and there is no current in circuitry. When transmitting terminal IC1 passes current, the receiving terminal will be breakovering, T1 is ON. And T1 is cut off, the signal of -12V will be sent to RS-232 by R4. From here, the circuitry realizes transmitting figure semaphore by using current ring.   (View)
