Data communication interface for an agricultural utility vehicle
First Claim
1. A data communication interface for an agricultural utility vehicle, particularly an agricultural tractor, having an interface connector (12) that can be connected either to a first data communication network (16) or to a second data communication network (18) by means of an electrically operatable changeover device (14), wherein the first data communication network (16) is terminated at a line end (20) associated with the interface connector (12) by means of a disconnectable terminating resistor (22), and having a control unit (28) that connects the interface connector (12) to the first data communication network (16) by means of appropriate operating of the changeover device (14) exclusively when it infers the presence of a control signal that is provided for disconnecting the terminating resistor (22).

Abstract
A data communication interface for an agricultural utility vehicle, particularly an agricultural tractor, having an interface connector that can be connected either to a first data communication network or to a second data communication network by means of an electrically operatable changeover device, wherein the first data communication network is terminated at a line end associated with the interface connector by means of a disconnectable terminating resistor, and having a control unit that connects the interface connector to the first data communication network by means of appropriate operating of the changeover device exclusively when it infers the presence of a control signal that is provided for disconnecting the terminating resistor.
