Do you use VLAN1 (untagged) as management VLAN on ZD?
If you have WEB access to AP, it must be in standalone mode, what is the status of management services on it? Please, publish screenshot. You need to enable them to connect to ZD. Also firmware of ZD must support R600.
It is weird that you can't ping other APs or ZD from R600, if you can connect to is through WEB -- what AP is R600 getting, is it on correct VLAN? I don't see how it is possible that you have access to AP, but can't ping other APs, if they are on same VLAN and subnet. If they are on different subnets, than you may have incorrect default gateway on AP.
