I don't think I'm alone in needing to upgrade my system. It will involve replacing the Ocelot but keeping my SECU16's. I'll need to talk to them via RS485. The protocol has always been called proprietary. With ADI not coming out with anything new in a long time, I think the protocol should be made available for personal use to the loyal ADI supporters who participate in this forum. Come on ADI it's way overdue. I would be willing to sign a Non Disclosure.
