Using 1x Crossover ethernet cable, 1x panelview+, 1x computer w/ ethernet port.
If the pv+ already has a static ip address: skip to next step, otherwise configure the pv+ to use a static ip address in whatever range(Use a non-routable address for this * 192.168.5.1 for this example*) , so 192.168.5.1 for the ip, 255.255.255.0 for the subnet, no gateway(if you have to set it, use 192.168.5.254), Ignore dns.
Now, Computer, Configure the ethernet port to be 192.168.5.2 ip , same subnet as above, same gateway as above if required, ignore dns.
Connect the crossover between the pv+ and the ethernet port on the computer you just configured(for ease of use, make sure this is the only ethernet port active *shut wireless off*)
Wait 2 mins and the application transfer application should see the pv+ w/ no trouble. If not, Reboot the PV+
