Should TFTP be binding to 192.168.0.50 the IP of the controller?
I then connected via telnet to the controller, ran the commands shown below and after a couple of seconds the controller shuts off and the telnet window says 'lost contact'. The ac3loader program never changes from the ready prompt above.

The other possibility is that some older 3 Pro units have a bootloader which will not ever work with the 'option A' way of updating the firmware. If that is the case, then you must use the option B procedure to update the firmware.

That was it. Option B worked. I guess that means I have an older unit and should always use B... Thanks everyone for the help.

but my controller is still flashing "power failure" on the status screen.

Updated my firmware today. The process was as smooth as it could be. I do have to agree with the others that I would prefer to have 3 graphs showing instead.
Unfortunately, Microsoft decided to make IE8 so that it can do 6 simultaneous accesses to the webserver - they did not put in any compatibility hooks that it would remain compliant with a http 1.1 webserver. Http 1.1 specifies that only 2 simultaneous requests can sent to any given server. The AC3 webserver can't handle 6 simultaneous requests, so we had to reduce the number of graphs displayed at once. If you want to see the graphs all at once access this URL: ac3_ip_addr/cgi-bin/graph.cgi. It is not officially supported, but it may work fine for you depending on which browser you are using.

Did you maybe accidentally plug the power xformer into the batter power rather than the main power jack??
