Guidelines for models that are not listed here
If your model is not listed here, you can try to locate the signals by yourself.
- try to locate 'dead-end' resistors (one pad is not connected to anything)
- the signals directly go to the ARM processor
- the signals level is 3.3v when the console is idle
- press INFO on the remote controller to generate traffic on the TX signal
- using an oscilloscope will ease this task
