Reflex XTR and Multiplex Cockpit MM.
I was given a Reflex XTR as a gift in 2005. It has never been used but has now been successfully installed on my older 'XP' computer. I would like to use it with my old 2003 Multiplex Cockpit MM transmitter, but I note that the Reflex interface cable has a 5-pin (DIN?) plug, and the transmitter has a 7-pin socket.
I'm new to RC and desparately need simulator time.

Any advice would be much appreciated.
Thanks in advance,
Andrew.
