Abstract
A cable test apparatus includes a power supply terminal, an open circuit indicator with an anode connected to the power supply terminal, a short circuit indicator, a first interface, a second interface, and a switch. The first interface and the second interface have a plurality of pins thereon. In the first interface, a first pin is connected to a cathode of the open circuit indicator, a second pin is connected to an anode of the short circuit indicator, a third pin is grounded, the other pins are shorted. The pins of the second interface are shorted as well. Therefore all wires of the cable are connected in series, even wires located at one side of the short circuit indicator, and odd wires are located at the other side of the short circuit indicator. In a short circuit test, the switch connects the second pin and a fourth pin; in an open circuit test, the switch connects the fourth pin and the cathode of the short circuit indicator and shorts the open circuit indicator.
