Bus node and plug-in connector for a communication bus system with bus termination configuration component

A bus node for a communication bus having end points, said bus node comprising:

• an interface circuit to said communication bus;
• said communication bus requiring a bus termination at least at the end points thereof;
• said interface circuit including a bus termination circuit arrangement;
• and,
• said bus termination circuit arrangement including at least a connection arrangement to at least one configuration component, wherein said configuration component comprises at least a first jumper, wherein said communication bus comprises at least one single twisted pair cable as physical medium, wherein said connection arrangement includes fifth, sixth, seventh and eighth contact clamps for second and third jumpers where said second jumper, when plugged-in or plugged-out in the corresponding ones of said contact clamps, connects a first bus wire of the twisted pair cable with a first end of a termination circuit and where the third jumper, when plugged-in or plugged-out in the corresponding ones of said contact clamps, connects a second bus wire of the twisted pair cable with a second end of said termination circuit.

A plug-in connector for connecting a communication bus having end points to a socket of a bus node, the bus node including:

• an interface circuit to said communication bus;
• said communication bus requiring a bus termination at least at the end points thereof;
• said interface circuit including a bus termination circuit arrangement;
• and,
• said bus termination circuit arrangement including at least a connection arrangement to at least one configuration component;
• said configuration component including first and second jumpers and said connection arrangement including a plurality of contact clamps;
• and, said communication bus includes twisted pair wires as a physical medium;
• said plug-in connector comprising:
• four of said contact clamps assigned to said first and second jumpers;
• two additional ones of said plurality of contact clamps assigned to said twisted pair wires of said communication bus;
• and,
• said first jumper connects the first twisted pair wire of the communication bus with one end of a termination circuit in said bus node when the first jumper is plugged in, and where said second jumper connects the second twisted pair wire of the communication bus with the other end of the termination circuit in said bus node when said second jumper is plugged in.
