Hello,

When Pulse shift polarity is defined in a model at "Positive", in Real is 
negative. And when "Negative" is Positive ..

Bye

Hi,

Sorry it took me so long to get back to you.  How do you measure the polarity?  
Do you have problems with your gear?

I'm asking because the gear I use outputs the correct polarity so I'm trying to 
understand why it's reversed on yours.  (maybe mine is reversed :)

Hello,

I'm use my oscilloscope for measuring. I have no problem with gear. I have see 
it when I have measuring ppm on jack for interconnect tgy9x with mc12. It's not 
a reel problem. It's just a constatation.

Thanks

In fact, 

I've see:
In a model when Pulse shift polarity is configure to "Positive", in real the 
PPM send to HF module or Jack is a PPM negative. And when is configure to 
"Negative", It's a PPM positive in real.

I've measure it with oscilloscope on pin PPM_OUT of Atmega64, after 4066 and 
final on Jack

It's more clearly now ... perhaps ...

Bye

PS: Sorry for my bad english ...

While this may be true I think in this case it's better to leave as-is in order 
to not create confusion.
