【 PoE Function】 Identify which pins are providing power and detect how much voltage.
【 PING Function】To test network performance, data packet, min & max time.
【 AC Filter 】Tone trace cable with complete AC Interference Rejection.
【 Hub Blink 】Hub blink for locating network port by the flashing port light on Hub / Switch.
【 TF Function】 To import and export data from comupter (160 sets, txt format).
【Warning】Please make sure to test on the POE/PING port during the POE test, if you test on other ports, it may damage the motherboard. The withstand voltage of POE/PING port is 48V or less, and the withstand voltage of other ports is 24V, if the test voltage is greater than the above voltage range, it may also cause damage to the motherboard, so please pay attention to it before testing.
