Question

I have problem trying to save the baud rate for RUT955 when using Modbus RS485 serial.  I had made changes for the baud rate from 115200 to 9600 and saved it.  when I execute the test, the baud rate reset to 115200 and give a message "Request sent

No response from slave device, check wiring and configuration"  My device only communicate at baud rate 9600.

Hi,

I didn't quite understand the question. The error shown a 9600 baud rate, do you want to use 115200 instead of 9600?

Also, do you have a modbus device connected to the RUT955? This issue will appear if you don't have connected devices.

Nevertheless, do you have the last released firmware? if don't, can you please upgrade it and test again?
