a second control unit which has a second termination path and a second terminating resistor connected to the second termination path; a first connector which is configured to connect the first control unit to the transmission lines and thus integrate the first control unit into the bus system; a second connector which is configured to connect the second control unit to the transmission lines and thus integrate the second control unit into the bus system; wherein the first connector and the second connector are designed differently from one another; wherein the first connector differs structurally from the second connector exclusively in respect of a line bridge in the first connector which is configured to connect the first termination path to at least one transmission line and thus integrate the first terminating resistor of the first control unit into the bus system; and wherein the line bridge is configured to be detachably insertable into the first connector. ### Claim 2 (depends on 1) The control system as claimed in claim 1, wherein the first connector differs from the second connector at least in respect of a line bridge in the first connector which is configured to connect the first termination path to at least one transmission line and thus integrate the first terminating resistor of the first control unit into the bus system. ### Claim 3 (depends on 1) The control system as claimed in claim 1, wherein the line bridge in the inserted state is configured to establish a permanent, non-switchable connection between the first termination path and a transmission line. ### Claim 4 (depends on 3) The control system as claimed in claim 3, wherein precisely one termination path having precisely one terminating resistor is provided in the first control unit. ### Claim 5 (depends on 3) The control system as claimed in claim 3, wherein at least two termination paths are provided in the first control unit and are provided in each case with a terminating resistor, and the termination path which is integrated into the bus system is selectable by the connector. ### Claim 6 (depends on 5) The control system as claimed in claim 5, wherein at least two first connectors are configured so that they in each case integrate a terminating resistor via the respective termination path of the respectively contacted control unit into the bus system, and at least a second connector is designed and configured so that the terminating resistor provided in the respectively contacted control unit is not integrated into the bus system. ### Claim 7 (depends on 1) The control system as claimed in claim 1, wherein the first connector comprises: a control unit side interface which is adapted to accommodate a first data transmission path, a second data transmission path, and a termination path; and a bus side interface which is adapted to connect the first path to a first transmission line and the second path to a second transmission line; wherein the bus side interface has a chamber into which a line bridge is insertable in order to connect the termination path to at least one transmission line. ### Claim 8 (depends on 7) The control system as claimed in claim 7, wherein the line bridge is inserted into the chamber. ### Claim 9 A method for configuring a bus system having at least two transmission lines comprising: connecting a first control unit having a first termination path and a first terminating resistor connected thereto to a first connector which connects the first control unit to at least one transmission line; connecting a second control unit having a second termination path and a second terminating resistor connected thereto to a second connector which connects the second control unit to at least one transmission line; inserting a line bridge into at least one of: the first connector so that an operative connection is established between the first termination path and at least one transmission line and the first terminating resistor is therefore integrated into the bus system, wherein the line bridge in the inserted state establishes a permanent, non-switchable connection between the respective termination path and at least one transmission line, and the second connector so that an operative connection is established between the second termination path and at least one transmission line and the second terminating resistor is therefore integrated into the bus system. ### Claim 10 (depends on 9) The method as claimed in claim 9, wherein the insertion of the line bridge into the first or the second connector is reversible. ### Claim 11 (depends on 3) The control system as claimed in claim 3, wherein precisely one termination path having precisely one terminating resistor is provided in the second control unit.
