My D700 attached to a Windows XP ran UI-View32 and programming via the MCP without issues via an RS232/USB adapter. That laptop died, and I can't make a connection with either my Windows 7 or Windows 10 laptops. This includes the RS 232/USB adapter and a cable with the USB connector on it.
I don't know what the difference between the COM & DATA ports are in this regard.
Any help in solving this issue is appreciated.
