Control plasma TV 42PC1RR

Connect

Connect your TV to Carambola using serial cable

Setup your TV to known ID. To do this, use your remote.
- Press MENU, select SPECIAL
- Select Set ID
- Adjust ID from 1 to 99. I left default, which is 1.

Setup carambola

Setup Carambola network. (I used Wireless as client (STA) mode). In this mode Carambola connects to my WIFI router automatically.
Install picocom to carambola

opkg update
opkg install picocom

I used USB 2 Serial converter, so I had to build custom firmware with enabled USB serial port support:

Under Kernel modules / USB support / kmod-usb-serial select all drivers if you are unsure which one you have or kmod-usb-serial-ftdi in our case.

Now you can test if it works. Run picocom.

picocom -f n -p n -b 9600 -i -r -l /dev/ttyUSB0

To power off your TV type (TV remains responsive, and you can turn it on remotely):
