Futaba 8JN Transmitter RF Pin Out
I am need of the pin out of the Futaba 8JN transmitter RF module. I has 10 pin connector.
I can probably trace the connections but would save some time if someone has done this. A friend wants to convert his 8JN to 2.4 Gig tomorrow.

We figjured out the pin out today using an ocilloscope. What my friend needed was ground, bat plus and the PPM stream. He wants to interface a FrSky Tx module. In was interesting to find out the PPM out in the back of the Tx is positive switching from ground to plus 9 volts. The PPM at the charge plug is going from Plus 5 to ground. The PPM signal out the back of the Tx worked, the PPM out the charge plug did not work with his FrSky module.
