Abstract:
1. A road paver comprising: an electronic control system which includes an operator's console at an operator's stand and a host system unit which is connected via a bus system with electronic subsystems and which has an inputting and indicating section and a memory area for machine parameter-data, the machine parameter data being installed and stored in the form of data in the memory area of the host system unit for parameterization of the road paver, a bi-directional data exchange port at the operator's stand which is connected with the host system unit, a passive data memory device, which remains at the road paver and is permanently plugged-in at the data exchange port, configured to save and externally store in redundant fashion the same machine parameter-data as already internally stored in the host system unit for retrieval by the host system unit after a service, a failure, or replacement, or a breakdown of at least the host system unit; and wherein the passive data memory device has an outer housing made of plastics materials and having at least one of a reinforcement against mechanical loads and a shielding against data losses, the housing containing at least one parameter data micro storage unit for parameter data and a first fastening mechanism that mates with a second fastening mechanism that is associated with the data exchange port to securely couple the two fastening mechanisms together.
