IR Emitter Control

When using an IR Emitter / IR Extender (sold separately), the IR Emitter must be mounted over
the IR Sensor on the front of the KD-VW4x4Pro. One end of the cable is connected to the IR
Receiver/ Master Controller / IR Extender / IR Connecting Block, while the other end is mounted
over the IR Sensor of the KD-VW4x4Pro

Serial IR Control

As a more robust alternative to optical IR, KD-VW4x4Pro may also be controlled via hard-wired IR.
Use a 3.5mm Male Mono plug with the IR Signal carried on the tip of the connector.
