Powered device (PD) test

This function is used to test the voltage, current, and power consumed by DC appliances. Connect the power adapter to the DC input (7).

Then, plug one end of the DC cable (included) into the powered device and the other end into the DC output (8). Select POWER (PD test) in

the main menu, and then press the OK button (12) to test.

Possible outcome is shown below:

Loop-back test

This function is used to check if the signal transmission between the network switch and the powered device is working properly.

Plug one end of the cable or the RJ45 patch cord (included) into the loop-back test port (3) on the transmitter and the other end into

the network switch. Select LOOP (Loop-back test) in the main menu. The device will send a signal to the network switch and wait

for the response signal. If the LED on the network switch lights up and "Loop testing…" is continuously displayed on the screen, it

means that the signal transmission is good. If the LED on the network switch does not light up, it means that there are problems in the

communication channel.
