Hi Team,

Customer is doing full-duplex config and wondering if RT needs to be placed on both side end of the bus?

Below we see different picture, so want to double check, thanks.

  • Hi Andrew,

    Thank you for reaching out to us!

    The termination resistor (RT) should be placed at both cable ends to remove line reflection.

    For full-duplex, it has two signal pairs (4 wires) and hence you need four termination resistors as shown

    in the below figure.
