5.5. Transmitting and receiving data is messy code
1, Check if the wiring is correct,our 485 wiring is 1A+,2B-.
2, Check if the line distance has exceeded the standard distance and the quality of the line (also by lengthening the line
transceiver or optical isolation)
3, Check whether the baud rate set matches the bottom device
4, Separate from the client's top software, use the network or serial debugging assistant can receive normal data, if you can
receive normal data, may not be compatible with the top software
