gc100 is a device which allows you to have remote conection almost anywhere. It's a network device which will forward all your data to :

• couple of serial ports
• IR senders and/or sensors
• several relays

For more details about the product check [1].

Send IR codes

Pluto implementation of GC100 assumes that in device tree we'll have children and the messages are actually addressed to them instead of gc100 itself.

So when you are sending "ON" to TV controlled by gc100, the message is routed to gc100, it fingds infrared code for "ON" for that specific TV, sends a command to gc100 to send a specific infrared sequence, which will blink IR sender connected to specific port, and the TV will turn on.

The only two commands that GC100 implements itself are : CMD_Send_Code used to test which IR is suitable for your equipment and CMD_Learn_IR used to learn new IR codes.

Learn IR codes

The learning device is actually unrelated to gc100. It may be plugged into one of gc100's serial ports (don't forget to set them to 9600 bps), or in regular serial port, just be sure you specified right port in gc100 device data.

There are several other devices that support learning of infrared codes : IRTrans, Tira, USB_UIRT.

Learning is done from web page. When clicking "Learn" gc100 will start a thread that will try to get data from the port. If nothing is received in 30 seconds the thread will die. The page will continue to refresh trying to see if anything was added, but after 30 seconds it's useless.
