DVI applications for the KD-CATHDX

synced. This includes the HDMI connectivity between source and
KD-CATHDXTx balun, Data and Video/Audio CAT5e/6 connectivity
between KD-CATHDXTx and KD-CATHDXRx baluns, and HDMI
connectivity between KD-CATHDXRx balun and display.
Extending Control Signals with KD-CATHDX

RS-232 control. Use the 3.5mm mono mini connection on the KD-CATHDXTx and
KD-CATHDRx.
