The IR Emitter
Understanding IR emitter?
An IR signal needs a clear line of sight in order to work. If you point an IR remote control in the opposite direction of the device intended to receive the signal, most likely nothing will happen. The signal transmission will not be effective. To avoid this kind of problem, all our IR control systems use local IR emitters. An IR emitter is basically, a remote control that is placed just in front of the device that you want to use and is connected to our control system by a wire.
IR emitter placement
You should mount the IR emitter with double sided tape on the front of the device you want to control. It is important to place the IR emitter directly over the IR receiver of the device to ensure reliable functioning (see Image 4). If you cannot see where the IR receiver is located, you will need to move the IR emitter around while testing the remote in order to find the proper place to mount it.
Proper placement and positioning
Strong sunlight can interfere with the receptions of IR signals. Placement in a location with minimum exposure to sunlight will return the best result. When you connect more than one emitter to an IR output, remember that the strength of the IR signal decreases with each additional emitter you attach. Therefore, proper positioning of the IR emitter is always important.
