I have bought Avionic RCB OS-10 transmitter for my airplanes. I have heard that its DSC port on front panel can be used for simulator training purposes, but I don't know actually how to use that port, since i tried connecting Aux or audio cable to that port and then plugging onto my PC's microphone port and then checked with smartpropoplus software for Joystick movements, but its not working. please help me how can i use that DSC port? I also have one more old Hobbyking 6channel basic transmitter which also have got a trainer port on backside, so i thought of modifying its PS2 connector on the back by soldering somewires from inside to the PPM line and one more to ground and then other ends to audio jack, and that method actually worked on simulator. But this new transmitter isn't. The old one is analog signals i guess so its controls are not accurate in simulator. So i wanted to use my new transmitter. please help me. Thank you.
