Point the remote control into a camera and push a button, if you see it blinking the remote control itself is okay.
Thank you

First, I've looked at the led of the remote

The led must be seen on the screen of the camera

Now, when I press button of the remote, it's like if I press a key of my keyboard.
/opt/bin/mediaclient --updaterc=3
Does this code is to set the driver only ? There is no button to press on the remote to configure it ? How to configure a remote if I have more than one Media Pro III ? Because I suppose that the Media Pro II doesn't send command to the remote.
