Hey guys, running on some problems here...

I am setting up my headtracker for my new Twinstar 2 project but my trackr2 won't work!
I bought a 4 pin mini din cable (just a standard s-video cable) And switched both ppm leads as in the trackr2 manual. In the EZuhf manual it states that the ezuhf will provide power to the trackr2 (i'm using 3s lipo on the ezuhf) through the mini din cable.

When I connect my trackr2 to the ezuhf the trackr2 just won't power up... I meassure 5 volts output from the ezuhf to the trackr2... Shouldn't that be 12 volts? The switch on the trackr2 is put in normal as in the manual and I plug in the cable to the trainer port.

Always hateful when your plane is ready except for that one thing!
