RX
1 to 15Ω
(Note) Please choose the most suitable
CX according to the noise level
and noise frequency of power
supply.
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 15Ω)
in the circuit drawing.
