Hi,
I have had no issues connecting to the RBM33G serial port for monitoring and control. I use Putty along with a WaveShare serial to USB interface.
I can only get gibberish back from the RBM11G when connecting the serial interface. I feel like I have tried every configuration, software and hardware connection, possible.
Has anyone had any success with the RBM11G serial interface and what were the parameters you used to connect?
Yes looks like you should use port A with the voltage switch set to 3.3. Do a loopback test of the converter by connecting the TX and RX wires together (not to the router) and test that whatever you type in the terminal echoes back. When you break the connection you should not see what you type.
