I am currently using the TXDU & RXDU command on a CS1. I have the TXDU functioning without any concerns. I am having difficulty seeing the received data (expected ACK 06). I can see the Reception Counter with the expected Nos of Bytes but when the RXDU is executed the count clears and no data in the allocated destination word D7000. I currently have the RXDU set up with no start or end code and the completion flag is used for the correct number of bytes.
I have also tried this using a different command which has a response of 2 bytes including end code 0D. Set up the serial settings to match, using the end code and I get the same issue. The RXDU is executed but no change of data in the Destination Word. expected 020d
Any advise much appreciated. What am I missing, ripping my hair out!!
