Ati remote

ATI remote/X10/Medion remote control

These 433 MHz remotes seem to produce a 21bit frame.

channel

There are 16 possible channels which can be selected:

• press the hand until the send led blanks as many times as the current channel.
• when the led stops blinking, press the channel 01-16. make sure the led blinks.
• press the hand/setup and check if the led blinks as many times as the selected channel.

r aaaa bbbb cccc dddd iiii 
r   = repeat/first
aaaa= bank + channel?/ checksum?
bbbbccccdddd = keycode
iiii= channel

checksum/bank?

For the lower/standard keys it looks like 0xE + channel but it's not consistent over the keys on the same channel. For example the "stop" key is 0xF + channel.
