Hello
I'm working on my first HART enabled application. The question I have is this:
The carrier detect pin goes HIGH when a valid carrier is detected. Therefore... in order to reduce the number of lines required to be isolated, can I do something like [if(CD) then (RX) else OUTPUT HIGH?] My understanding is this: Valid frames are delivered only AFTER the CD pin goes high. Some garbage data may be coupled after the last frame before the CD pin goes low. So is this feasible?
