#63023 - Problem using RS-485 (75176) with 89C55 |
I´m using the serial port of 89C55, then I conect a 75176 (converter TTL to RS-485). If I use only the serial port with a MAX-232, the comunication is perfect, but when I conect de 75176 then comunication fail, sometimes the micro can´t be reset, I got to turn off the power. I know that the 75176 change the pin RX when I put him on Reciver or Transmiter. If you who solver that problem, please send a mail.
