Hello,

OK, if no one can answer my questions about the 518 into the 568, can anyone tell me what firmware the 568 should be running and where I can get any upgrades but it’s an old version?

It should arrive tomorrow and I would like to make any updates before installing.

Thanks for any help.
Andy
