摘要
A digital tachograph unit (TCO) includes a continuous voltage input (DIN), an ignition voltage input (ZIN) and an activation voltage input (AIN). A continuous supply unit (VSD) is coupled to the continuous voltage input (DIN) and is configured to supply a continuous supply area of the tachograph unit (TCO) as a function of a voltage at the continuous voltage input (DIN). An operation supply unit (VSZ) coupled to the ignition voltage input (ZIN) and the activation voltage input (AIN) is configured to electrically connect an operation supply area of the tachograph unit (TCO) in response to a voltage at the ignition voltage input (ZIN) and / or the activation voltage input (AIN) to supply. A data processing module (MC1), which is assigned to the continuous service area, is set up to carry out data transmission via an interface module (SM1), which is assigned to the operating service area, as a function of a concern of the supply voltage (VB) at the activation voltage input (AIN).
