Do I need terminating resistors? What value should they be?

Yes.

RS-485 and networks based on RS-485 (CANopen, DeviceNet) require terminating resistors on both ends of the bus. Only true bus topology is supported. Star, mesh, and other network topologies are not supported.

We recommend using a 100-120ohm terminating resistor.
Did you restart it?
