Hi there, We are planning to configure I/A 7.0 system with mix of Ver 7.0 and 6.4 (XP & NT). There will be 3 stations on I/A 7.0 and 1 station on I/A 6.4. It will be using non-redundant Control Network configuration. Based on B0193AC document, there was no splitter cable used at all. Is that only apply to I/A 7.0 (XP) only or it apply to all the stations (XP and NT)? Earlier, I saw a document stating that if you have I/A 7.0 running, you'll use NCNI and you can throw away all the DNBIs and DNBTs. Is this correct? Based on the documents, there will always be two versions of I/A 7.0 Day0 CD (redundant and non-redundant). Thank you.
