I am working on a project with R-90 as the vehicle. Today I want to connect the FF9 transmitter to an FM transceiver, but I find that the FF9's connector type is the "square" one. This type is so different from the original type.
From Google, I find some website describe the pins of the FF9's connector:
Of course, I check all the pins with the oscilloscope to make sure everything is OK. I also get a female 6-pin DIN plug from an old FF4 transmitter.
Finally, I make a new connector cable with 2 different plugs. It works. :-)
