Depend on noise level and noise frequency of power supply, CX does not work well. There are cases that some pulse noises from RXD other than signal will occur in certain communication area. Please check by finish product that there are no problem at all communication area and data rate. If there are any problem, please check by inserting RX (1 to 10Ω) in the circuit drawing. Pin 1 and 2 are not connected internally.
