Thanks for the input BIGPHIL!

You must have something other than the RF Deluxe Serial Port Printer Transmitter Interface or the RF G2 USB Software CD...or you've figured out something the manufacturer doesn't acknowledge.

Both the Seller of the Real Flight G2 USB Software CD and Great Planes, the manufacturer?/distributer of the Real Flight Simulators
say that the RF Deluxe Transmitter interface defiantly will not work with RF G2 USB. The Software looks for a USB control device
and actually will not start to run unless it finds the USB control device included with the software.

The Real Flight Add-ons will work with either the Deluxe (or Standard? or Custom?) and the G2.
