RAJOD - Yep, Chart Links are dead. The info/thread began quite a while back...maybe not being maintained???
I just purchased the APEX, based on all the info I recently reviewed over the last month or so, and RC members discussing/comments. I felt very comfortable with the future of Neptune and level of support they seem to be providing to their customers. Now installed on my tank....all I can say is wow. I'm very pleased with the Apex and look forward to interfacing more hardware in the fish room to it with the expansion modules. Even thought about hooking home security window/door switches to it and controlling an audible alarm with it. If my Toro yard sprinkler controller crashes, I will be building an interface and move that onto the Apex. Yep, I'm a DIY freak.
