Download ppjoy. When it is downloaded go to the "ppjoy" folder. In there is "setup.exe". Open that and it will install the folder "parallel port joystick". Then go to control panel and open "parallel port joysticks" which is a "configuration utility for joysticks that plug into the machines parallel port". Open that. Click "add". It will open the "configure new controller" window. Then change the "parallel port" drop down from "LPT1" to "virtual joysticks". Plug in and turn on your transmitter then click "add". Then ppjoy will go through downloading whatever it needs to and it may take a while. After that to use your transmitter on fms you need to do this. Open "ppjoycom" in the "ppjoy" folder and change the "serial protocol" to "zhen hua 5 byte protocol" then turn on (and plug in) your transmitter. You will see the "waiting for stream int..." change to "reading serial stream...". Then open fms (leave ppjoycom open reading the serial stream) and go to the "controls" toolbar then in that go to "analog controls". Then change from "no interface" to "joystaick interface". Then click mapping calibration. Change the numbers to the same as the picture down the bottom and then click "calibrate" and follow the instructions given. This process work perfect for me and there used to be a website with all this info on it but now it doesn't exsist I've had to sit here for 45mins typing it out. I really hope these 45mins make you able to use fms...
