Remote file transfer without J716 FTP interface

My company just bought a used robot (ArcMate 120iB; RJ3iB controller). I thought that J716 was a standard option, but apparently not. Is there any other way to make backups and transfer files over the network or am I stuck with the MC as the only way to transfer? I've attached my summary.dg if anybody wants to see what options I have that might help.

Thanks.
