7.2 PD powered detected
PoE switch or PSE power supply device connected to the "PD" port of the wire receiver, if the indicator light is on,
it means PoE voltage output working normal. There are 2 indicators lights of the "PD" port, when testing
the pins used of PoE switch for power supply, if 1236 indicator light is ON, it means PoE switch supply power
through Pin 1236. If 4578 indicator light is ON, it means PoE switch supply power through pins 4578. If 1236 and
4578 indicator lights are ON, it means device power supply through pins 1236 and 4578.
If the indicator light is lighting on, that is non-standard PoE. If the indicator light is flashing, that is standard PoE.
It also supports 24V and 48V PoE supply power device. The lamp brightness of 24V PoE is relatively dark, and the
lamp brightness of 48V PoE is relatively bright.
1236 pins supply power
4578 pins supply power
1236 and 4578 pins supply power
Application: Checking the pins used of PoE switch or other device for power supply, to avoid cause cannot supply
power or camera and other device damaged. Can detect the voltage of POE power supply device, PoE is standard
or non-standard.
7.3 Telephone status
Telephone status detection: If detected the telephone status, please turn off the cable tester. The RJ11 indicator
light flash is ringing, the indicator light on is standby, the indicator light off is off-hook.
Positive/negative polarity detection: Turn off the cable tester, the red and black alligator clip of RJ11 to clip the
cable. If the indicator light is red, that means the red wire clip is positive, and the black wire clip is negative. If the
indicator light is green, that means the black wire clip is positive, and the red wire clip is negative. The level higher,
the indicator light is brighter, if the level lower, the indicator light is darker.
