X.Org setup

No special setup needed, EDID is reported correctly on HDMI port and X defaults to the 1080p@60hz mode. A "Just Scan" aspect ratio mode is present for 0 overscan. A 24fps 1920x1080 modeline is also available through xrandr.

RS/232 Control

A hacker's dream. Standard interface with well documented commands all in the standard user's manual. Works out of the box on a Linux computer with serial port and nullmodem (reversed) cable and using terminal commands like:

echo 'kf 01 1a' > /dev/ttyS0

(sets volume to 10%).

It even acknowledges commands and allows queries:

cat < /dev/ttyS0 &
echo 'kf 01 FF' > /dev/ttyS0
f 01 OKNNx
where NN is the volume percentage (in hexadecimal).

Commands available to control every function including power on/off, and even emulate IR codes.
