Hey,

i need to communicate an ingersoll rand compressor to the delta v (emerson) via a serial card. But I can't be able to do this job. i know that i have to use the ucm to communicate but i get the error illegal data address or error response. What should i do? i connected half duplex and full duplex but it doesn't work. I am using rs-422/485
