Configure 9205 in 9144 via EtherCat Master for Differential mode

[Strykertool]

We have a 9205 module in a 9144 EtherCat Module.   It seems we can configure and read an analog test voltage wiring it for Single Ended Mode but we can't figure out how to configure it to read a channel in Differential Mode.    We have a chart that shows how to set config bits for single ended but diff mode is not listed?   Can this be done and if so how!

Thanks

Greetings Strykertool.

You might have a look at the following example, specifically the file "NI 9205 Gen Configuration (Host).vi".  If this doesn't help shed some light on things, please let me know.

OK that helped us a  bunch.   We got it working fine.    We had a documentation sheet that showed the NRSE and RSE mode values but nothing about Differential.   We guesed correctly but didn't get it to work because we didn't have all the channels we needed set to the same mode.   We are still unsure of how I  guess you could call it the "banking" of channel properties works but when we set them all to Differential mode this time it worked fine.   The example you gave confirmed we were on the right track and that helped us find the other problem.   Thank you very much for the help, this one really had us stuck for a while.
