RS-232/RS-485 Protocol Translator
Figure 15 shows the MAX3162 configured as an RS-
232/RS-485 protocol translator. The direction of transla-
tion is controlled through the RTS signal (R1IN). The
single-ended RS-232 receiver input signal is translated
to a differential RS-485 transmitter output. Similarly, a
differential RS-485 receiver input signal is translated to
a single-ended RS-232 transmitter output. RS-232 data
received on R2IN is transmitted as an RS-485 signal on
Z and Y. RS-485 signals received on A and B are trans-
mitted as an RS-232 signal on T1OUT.
Ну вот же всё по человечески написано.
RTS рулит направлением.
Данные RS-232 с ноги R2IN транслируются на Z и Y, а с A и В - на T1OUT.
Это по вашей схеме.
Программирование делится на системное и бессистемное. ©Моё :)
