Default Old Futaba tx pinout?

Found this pinout for the Futaba FP-TP tx module that's in the 3PJ, 7U, 8U, 9C & 9Z:

looking at the back of the transmitter, antenna pointing away from you:

left side
#1 PPM
#2 switched battery positive
#3 RF good (pulled low through a transister when signal is present at the final amp)
#4 ground
#5 RF out
right side

I knew my old 3EGX modules were 10 pin but when I opened one to have a look the pins are tied together so the result is only 5 inputs to the module:




So using the same orientation as previous, pins 1/2, 3/4, 5/6/7, 8/9, 10 feed the tx. Any idea whats what? Any way to find out?

Guess you figured where this is going. Here's the FASST unit that replaces that FP-TP module:

Here's a conversion board I made so the old FP-TF transmitter can take a TP module. Hope this helps.

Thanks for that. Talked to a reputable repair facility that just recently did a conversion on the 3EGX, apparently there's more to it than just matching up the pins. Good to know it works tho!

I have Futaba T8JN and tried to convert into 2.4GHZ so stated measure pinouts and this is what I found.

Pin 1/2 PPM 10V Max
Pin 3/4 +
Pin 5/6/7 _
Pin 8/9 ANT
Pin 10 RF Pull

Hope this can help...

In my opinion, you may have to use trainer port PPM to convert 2.4GHz and it has PPM amplitude of 3.2V.

Long shot request from 13 years ago; but, can you elaborate on the Pin 10 RF Pull? Is this for the output meter?.

Finally pulled my T5JN and T6JN out of storage and converting them over to FrSky 2.4ghz modules.
