Hi all.
I have two design:
1/ RS232 to Rs485 converter
I use Txd, Rxd from PC ==> max232 => opto => max3089. I use RTS(from PC) to control DE and /RE pin max3089
2/ USB to Rs485 convert.
I use USB=>> FT232RL => opto => max3089. I use CBUS2(pin 13 of FT232RL) to control DE and /RE pin max3089.
With 2 this design I can send/receive data to the device with speed <= 38400 baud, the data good,
When I send/receive with speed as: 57000,...,115200, the data error.
I don't understand that.
Could you help me,pls?
Thank you,
