Calibration

Plug one end of the cable (min. 10m) with a known length into a corresponding port on the transmitter (RJ45 MAIN port for a network

cable) and leave the other end of the cable disconnected. Select Length on the main page and press the OK button (8). Choose the required

cable type and then select Calibration. Adjust the result if needed using the ▲ and ▼ buttons and press the OK button (8) to save the data.

For more precise results, it is recommended to calibrate the device on a cable with a known length from the same manufacturer.

Usage

Plug one end of a tested cable into a corresponding port on the transmitter and leave the other end of the cable disconnected. Select Length,

choose the required cable type and then select Load data. Choose the calibration result that you need from the list and press the OK button

(8) to load it. Press the Back button (9) to return to the main menu.

Select Length and choose the required cable type. Select Cable length and press the OK button (8) to test.

Possible outcomes are shown below:

Normal (coaxial cable) Short (telephone cable)

If the results for each pin dier noticeably, consider the result for pin 3 to be the reference value for the network cable length (the

pin 4 result for a telephone cable and the pin 2 result for a coaxial cable respectively).

Network connection test

This function is used to check if the cable connection and the network equipment operate correctly. Plug one end of the RJ45 patch cord

(included) into the RJ45 MAIN port (3) on the transmitter and the other end into the wall socket or to the network switch directly. Select

Mapping, choose the RJ45 cable type, and select Start to test.

Possible outcomes are shown below:

Network connection is correct Breakage on pins 1, 2

PoE test

This function is used to identify the pins that provide PoE and to measure PoE voltage. Plug one end of the cable or the RJ45 patch cord (included)

into the PoE/Ping port (6) on the transmitter and the other end into the PoE source equipment (such as network switch, router etc.). Select PoE in

the main menu, and then select Start to measure the PoE voltage.

Possible outcome is shown below:

Ping test

This function is used to test data transmission. Plug one end of the cable or the RJ45 patch cord (included) into the PoE/Ping port (6) on the

transmitter and the other end into the PoE source equipment (such as a network switch, router etc.). Select Ping in the main menu, and then

select Congure before starting the test. There you can setup the IP address, the local IP address and the data packet setting or let the device

obtain it automatically.

Press the Back button (9) to return to the previous menu and select Ping, then select Start to test. Possible outcome is shown below:

Port Flash function

This function is used to locate the exact port on the PoE switch or router to which the cable is connected. Plug the loose end of the cable into the

PoE/Ping port (6) on the transmitter (the other end is connected to a PoE source equipment) and select Flash Port in the main menu. The circle

on the display and LEDs under the PoE/Ping port (6) will ash with the same frequency as the LED of the target port on a PoE switch or router.
