Abstract (en)
A remote control with a two-wire interface has a number of control keys with associated resistors. The resistance value that can be measured between the terminals of the two-wire interface is translated into a command by the interface circuit of the device to be controlled. A hold switch is arranged such that a DC path is always present independent of the position of the hold switch. The interface circuit of the device to be controlled is designed such that even when the device is in a low-power or off-mode and the hold switch is activated the operation of a control key can be detected and a message or indication can be issued. The user is thus informed about the status of the hold key.
