1. A branching device for a transmission line, comprising:
- a main transmission line including at least two signal lines and having respective connectors provided at either end;
a first branch transmission line comprising a branch-use connector at an end, and at least two branch wires, each branch wire branching from a respective signal line;
a second branch transmission line comprising a branch-use terminal block at an end, and at least two branch wires, each branch wire branching from a respective signal line;
a terminating resistor having one end connected to one of the signal lines that branches into both the first branch transmission line and the second branch transmission line; and
a selection switch that is operated to connect the other end of the terminating resistor with an other one of the signal lines that branches into both the first branch transmission line and the second branch transmission line.

Abstract
A branching device for a transmission line, including a main transmission line including at least two signal lines and having respective connectors provided at either end; a first branch transmission line which branches from the signal lines and which has a branch-use connector at an end; a second branch transmission line which branches from the signal lines and which has a branch-use terminal block at an end; a terminating resistor having one end connected to one of the signal lines; and a selection switch that switches the other end of the terminating resistor between connecting with an other one of the signal lines, and forming an open circuit.

13. A device for monitoring or testing components, comprising:
-
a first line; a second line; a ground line; a plurality of signal lines; a first connector connected at one end of the first, second, ground and signal lines; a second connector connected at an opposite end of the first, second, ground and signal lines; a plurality of resistors, one end of each resistor connected to the first line; a rotary switch having a connection for each resistor at each resistor'"'"'s opposite end and an open position, a fixed end of the rotary switch connected to the second line; and at least two branch transmission lines, each branch transmission line having three lines, a line connected at one end to each of the first, second and ground lines, and an opposite end of the three lines connected to a terminal block. - View Dependent Claims (14, 15, 16)
