Step 1: Open up LP5DSM Transmitter
Take out the 4 screws holding the transmitter together and flip it open. Be careful not to rip any of the wires.
Step 2: Split the serial signal and tap the GND signal
The serial signal wire is the grey one - cut it in half. The ground wire is the black one - solder an additional GND wire at one end of the main GND wire. Put some sort of connector onto the ends of all three wires, and route it outside the case.
Step 3: Wire up a cable from the LP5DSM to the FT232 serial board
Step 4: Install Java 6 Update 3
If you don't already have it, install the latest version of the Java runtime. 1.6.0_03 is the version I use, but you can probably use a newer version without issues.
Step 5: Install FT232 D2XX driver
Unzip jd2xx-msw-20070409.zip. Plug in the FT232 USB Serial breakout board into a USB port on your computer. When prompted for a driver, use the one found in the ftdi directory of jd2xx-msw-20070409.zip.
Step 6: Install CopterController
Unzip CopterController_1.1.zip to a directory of your choice.
Step 1: Connect FT232 Serial Breakout Board to LP5DSM Transmitter
Make sure you have the TX and RX hooked up correctly, otherwise you may let out some magic smoke. Double check this before plugging the serial breakout board into the computer or before turning the LP5DSM on.
Step 2: Turn on LP5DSM Transmitter
Step 3: Run ControlDemo.bat
Go to the directory where you unzipped CopterController, and run ControlDemo.bat
Step 4: Enable LP5DSM Interface
Ensure that the throttle slider is set all the way down, and change the interface from "Disabled" to "Enabled".
Step 5: Plug In Helicopter Battery
Turn on the Blade CX2 helicopter by plugging in the battery
Step 6: Move Sliders To Test Response
