Where should the green wire of the monitor be connected?
The green wire (CH3) should be connected to the positive 12V/24V power supply if using a camera as a reversing camera. If this function is not desired, the green wire does not need to be connected.
What is a 12V/24V power supply in the context of this monitor?
The monitor's red wire must be connected to a positive 12V or 24V power supply. This is the voltage required to operate the monitor. Vehicle electrical systems typically provide either 12V or 24V, and the monitor is designed to work with either of these voltages. 12V is generally used in cars and small vehicles, while 24V is more common in trucks and heavy vehicles. Using an incompatible power supply may damage the device.
