Here is the resume of my findings.
HP 8600 – No connection possible either with the Keyspan USB – RS232 or directly with the DataPort box. Both connections are live
Z400 – Intermittent connection possible using Keyspan USB – RS232 but check decks does not work. I can only connect by using a manual config and after many attempts.
I have 6 suites all connected to the Videohub that I cannot digitise out dump from. This is nothing short of a disaster. Please can someone at BM put on line a fix very quickly or an old install so I can now use my installation. For that matter, I can only find a mac download on the BM website.
