Hi,
We're you able to locate the Datronics Protocol Reference?
I'm trying to send RTD data to a Venus/7000 also.
Since I have limited access I've been using RtdTst.exe and my messages are accepted and ITF fields are updated properly.
When I tried it on V7 nothing happened. Since my last test I've figured that the checksum was wrong and the IP port number I configured on the V7 may have been too low.
Do you have access to a V7 for testing?
Together we may be able to figure it out.
