Setting up a correction link - Arducopter integration?

Dear Mikhail,
here is my cable connection:

I have connected a separate power source to pin 5 V and ground. The Reach M2 module also starts and can also be accessed with Reachview.
In addition, I also tested the original connection cable from EMLID, also the same result, no GPS signal on the GPS2 port from Pixhawk.

But I get GPS injection signal in.
If you wish, i can send you Mission Planner settings file.
Thank you very much.
