The CD_ADJ input of the GS9024 is biased via a resistor network including a potentiometer allowing the user to adjust the level at which loss of carrier is detected. For a detailed description of the CD_ADJ voltage level versus muting threshold refer to the GS9024 data sheet. Turning the potentiometer completely clockwise allows for maximum possible cable length equalization. In addition, the GS9024 outputs can be put in a HIGH-Z state by putting jumper JMP1 into the 1-2 position.
