What Is IR?

Many devices connected to Caavo can be controlled directly and reliably using IP (internet protocol), BT (Bluetooth) or HDMI-CEC (Consumer Electronics Control) protocol.  However, there are also many devices that don't use these methods (e.g. TV, cable box, TiVo, many BluRay players, some AVRs, etc) so Caavo resorts to using IR (infrared) control.  IR signals are digitally-coded pulses of infrared radiation to control functions such as power, volume, and channel changes.  These devices require a direct "line of sight" with an IR transmitter to work properly.  If the "line of sight" is changed/blocked, or the transmitter is moved out of alignment, IR control can become sporadic or stop working altogether.

Due to the nature of IR, it can be difficult to troubleshoot, because it cannot be seen with the naked eye.  Try using a digital camera (your phone's camera should work; iPhones use the front camera) to "see" the Infrared signal blasting from the Caavo box as well as any attached emitters. The Caavo box has two emitters on the front and one on each side that will light up when issuing IR commands like Volume UP/Down.  This is also a good method to determine if your IR transmitter is actually sending a signal or not.
