5.2 Connecting Cables for Testing

Before connecting any cables, ensure they are disconnected from all active network devices.

• For patch cables (uninstalled cables): Connect one end of the cable to the RJ45 port on the main unit and the other end to the RJ45 port on the remote ID locator.
• For installed cables: Connect the main unit to one end of the installed cable (e.g., a wall jack) and the remote ID locator to the other end of the cable (e.g., in a patch panel).

6. Instrucciones de funcionamiento

6.1 Encendido / Apagado

The device typically powers on automatically when a cable is connected and the TEST button is pressed, or by pressing the TEST button. It usually powers off automatically after a period of inactivity to conserve battery.

6.2 Realización de una prueba de cable

1. Ensure the cable is properly connected to the main unit and the remote ID locator.
2. Presione el PRUEBA botón.
3. The tester will automatically scan the cable and display the results on the LCD.

6.3 Interpreting Test Results (Wiremap)

The LCD will display the wiremap, indicating the connection status of each wire pair. Common indications include:

• Aprobar: All wires are correctly connected (1-1, 2-2, etc. for straight-through, or appropriate cross-over mapping).
• Open/Discontinuity: A break in one or more wires. The display will show which wire(s) are open.
• Cortocircuito: Two or more wires are touching. The display will indicate the shorted wires.
• Incorrect Connection/Miswire: Wires are connected to the wrong pins at one or both ends. The display will show the incorrect mapping (e.g., 1-3, 2-6).
• Pares divididos: A more complex fault where two pairs are swapped, but the wiremap appears correct. The tester is designed to detect this.

6.4 Measuring Cable Length

1. After performing a test, press the L / W button to switch to Length measurement mode.
2. The display will show the estimated length of the cable.
3. To change the unit of measurement (meters, feet), press the SET/UNIT button while in Length mode and use the arrow buttons to select the desired unit. Press SET/UNIT De nuevo para confirmar.

7. Mantenimiento

7.1 Limpieza
