"It's been a long time since I got into the radio but as I recall the reason I connected on the inside is that I couldn't get the Taranis to connect through the trainer port. The 9xR did work through the trainer port but not the Taranis. Plus…"

"I can't get the pictures to load. You got them though when we first started this. You PM'd me and I replied with pictures.But, it's pretty simple. On the INPUTS page 6/13 I renamed input 6 "MODE" and made the SOURCE TR1. 
On the Mixer page 6/13…"

"If you set up your mixing screen like in the pictures it will work. (probably)  I should have posted those pictures here instead of in the messages part. The Arduino program sets the value of PPM-1 to a set number for each output. If it's working…"

"On your back board next to the right had ribbon connector is a pattern of six solder pads. In that six pad pattern the left pad is the signal and the lower right, or second from the right is a ground. Those are coming from your trainer port. On your…"

"There aren't any labels around the ribbon cable sockets? Maybe on the back side? Looks like you are going to have to get out the multi meter and find the 3.26 volts (on mine)  and a ground. those are fairly easy to find. I'll trace my signal wire…"

"There should be a wire on the back cover PCB that is marked TR_PPM. That is the signal. There are also two wire positions marked Vcc and GND next to each other. That's where the 3.26 volts comes from."

"I say Hmm.... I'll take my radio apart later tonight and see if we can find some common markings. Is your radio the new one? The plus or something like that? Mine is an "old" one but the PCB is probably printed with common markings. "

"First off a disclaimer. I have not had to play with the Arduino coding. I've looked at it and modified it but have not written a program from scratch. I've put Stefan's code in several radios and haven't had to modify it. That's a great little piece…"

"Holly smokes!! You've taken mods to a whole new level."
