Ok, that one is powered.. so it should be OK..
SAMBA protocl, is SMB.. its a type of file connect.. often used between windows/mac/linux for file sharing on a network... little more universal than windows file share
Try maping a drive with this format
smb://ServerName/ShareName
So smb://youripaddress/
and the sharname possibly as it you had it working on the one above?
Unfortunately, thats about all the documentation says on it :(
Maybe next would be to put in a support ticket with Hitron? They might be able to send you the right info.
