I spoke to a friend who just did the newest firm ware update. I have not done it so I am quoteing someone else,but it is a person who I trust and he also really helped me get thru the apex and the vdm programing. If you do the latest firm ware update be prepared to completely reprogram yourmApex !! He had to identify all his outlets and reprogram them. Since he is running six dc -8's I will take his word on it and will hold off tell he has time to help me thru it !! Lmao. I do love the app tho !!
