protocols of remote controlers

[chava]

Hello all
I have a remote control, design for air conditioning systems.
The transmitting is by infra-red or led.
I need its protocol.
I searched for its model (LCDG2) on the internet, but no results were found.
is there any knowe protocol for devices like this?

if you can receive the datastream, I am sure you can easily figure it out.. perhaps just hook a scope up to the transmitter diode and capture the pulse train for different key presses...
