PURPOSE:To avoid the unstable state of a receiver by providing a circuit to give a prescribed differential voltage to a network, inside a terminal resistor, and supplying a power source from a node, in which the terminal resistor is packaged. CONSTITUTION:The terminal resistor 6 is connected only to two nodes 1, installed at the both ends of the network 2. The terminal resistor 6 is provided with a terminal resistor 5 and the resistor 8 to pull-up a pair of the transmission lines of the network 2, and the resistor 7 to pull-down the same, in its inside, and when it is connected to the node 1, it receives the supply of the power source of +5V from the node 1, and terminates the network 2, and at the same time, it generates a differential potential difference on the network 2 by means of a divided voltage due to the resistors 5, 7, 8. Thus, the disorder of the receiver of all nodes can be improved.
