Jetson nano connect to pixhawk 3dr radiolink

Hello community,

I am building from scratch an autonomous quadcopter using pixhawk 3DR with the jetson nano. the problem is that i can not figure the connection from the telem2 of the pixhawk to the jetson nano. i do understand the pins connection RX TX and GND from both pixhawk and jetson but i can not find a cable to connect them. also pixhawk telem2 should be a df13-6s female adaptor but i already got two different df13 and they do not fit.

sorry for posting this question again because the previous solutions did not solve my problem

THANK YOU FOR TAKING YOUR TIME TO READ, AND RESPOND

Hope someone has experience can share, just remind that the TX, RX should be swapped between pixhawk and jetson.
