Question

Hello.

I would like to clarify my question.

I am using the TRB145 LTE RS 485 Gateway to receive data from the Internet. I take the received data from the RS 485 port. I would like to know the physical parameters of the RS 485 - the amplitude of the signal and its polarity. According to my measurements, the signal swing is only 2.5 V and it is unipolar.

Is it really true?

Best regards, George.
