I'm trying to hook up my transmitter to fms, but it's not working. I just bought the usb/tx interface cable but it appears as though the tx is not being recognized. Whenever I try to calibrate, nothing happens.

Iv'e done some searching, but can't figure out my problem. Iv'e already tried two transmitters- my hitec optic 6 and a laser 4. Same problem.


Any help?

Thanks!
