Router system for transmitting data between at least two different data networks, the router system comprising a configuration device arranged in the housing of the router system for creating, storing and managing at least two router configurations, characterised in that the router system comprises at least one receiving device, by means of which at least three different trigger signals can be received, and the receiving device being connected to the configuration device via a data connection and the configuration device being suitable for activating a different router configuration from the router configuration that is active at the time the trigger signal is received, depending on the at least three different trigger signals in the router system, at least one of the trigger signals that can be received by the receiving device being a trigger signal selected from a group comprising a) arrival of an e-mail message that is regularly checked by the router for new messages, b) exceeding or falling below a specified temperature, measured by sensors in the housing of the router or by an externally connected temperature sensor, c) exceeding or falling below a specified value of the external supply voltage, d) failure of one of two or more applied external supply voltages, e) detection of a switching process at a digital input of the router, f) exceeding or falling below a configured voltage value or a current value at an analogue input of the router, g) receiving a short message from a cellular-capable router, h) reaching a certain time of day, i) elapse of a defined period of time (stopwatch), j) event due to detection of a USB device plugged back into a USB port of the router and k) event due to received data via a serial interface, any change in the configuration of a router being referred to as a change of the router configuration, this change being the at least partial change of configuration profiles, and the receiving device being suitable for receiving trigger signals which are selected from a group comprising i) an event due to failed authentication for configuring the device, t) an event when the free RAM storage of the router is not reached. a) arrival of an e-mail message that is regularly checked by the router for new messages, b) exceeding or falling below a specified temperature, measured by sensors in the housing of the router or by an externally connected temperature sensor, c) exceeding or falling below a specified value of the external supply voltage, d) failure of one of two or more applied external supply voltages, e) detection of a switching process at a digital input of the router, f) exceeding or falling below a configured voltage value or a current value at an analogue input of the router, g) receiving a short message from a cellular-capable router, h) reaching a certain time of day, i) elapse of a defined period of time (stopwatch), j) event due to detection of a USB device plugged back into a USB port of the router and k) event due to received data via a serial interface, any change in the configuration of a router being referred to as a change of the router configuration, this change being the at least partial change of configuration profiles, and the receiving device being suitable for receiving trigger signals which are selected from a group comprising i) an event due to failed authentication for configuring the device, t) an event when the free RAM storage of the router is not reached.
