I am newbie in this field.
I have two AD5700 hart modem, I connected it with AD5421. signal output of AD5700 is very good 1.2 and 2.2 Khz sin wave frequency fed to Cin of AD5421, but the output of the AD5421 is fix 1.2 KHz (approx) freq seen by oscilloscope with much noise.
When I connected output to Hart modem for receive signal it give garbage only.
my baudrate is 1200 for communication.
