#121822 - 485 connection with 8051 |
Dear all,
I am using RS232 serial communication with 8052 chip. My other device is running for RS485 connection. I have used 232 to 485 converter for communication. But i want to remove 232 to 485 converter and want to connect directly 485 with 8052. Can anybody have idea for that, schematic also. Thanks. |
