摘要： The present invention relates to radio engineering, in particular, to methods for transmitting signals between devices. A technical result provided by the present invention is a simpler design of circuitry for signal transmission between a master devices and slave devices connected thereto.
According to the method for transmitting signals between a master device and at least one slave device, the master device has at least two external first-kind contacts, at least one internal power supply line, a voltage measurement means and at least one external second-kind contact connected directly to the voltage measurement means and, via an impedance, to one internal power supply line. The method comprises: detecting a connection between one of the master device second-kind contacts and a slave device by determining the voltage at such second-kind contact; identifying the master device first-kind contact to which the slave device is connected by setting different voltages at the first-kind contacts and determining the voltage at the second-kind contact; changing the voltage between the first-kind contact to which the slave device is connected and the internal power supply line connected, via the impedance, to the second-kind contact to which the slave device is connected; generating a signal in the slave device by changing resistance between the contacts connected to the master device; receiving the signal in the master device by measuring the voltage at the second-kind contact to which the slave device is connected.
