So what is the link to this Firmware version 3.62? I assume with the mention of FW 3.15 that this is a VP2? Latest FW version for the VP2 (that Davis wants anybody to know about anyway) is FW 3.80, never heard about or seen a FW version 3.62.
And just to complicate things there is actually a FW version 3.83 that Davis does not want anybody to know about.... apparently? Why not, have absolutely no idea, more Davis secret squirrel crap
