As we know, a RJ45 cable is used to connect two devices to transfer data. RJ45 cable plays a critical role in the network connection as it is a key component in modern technology. However, sometimes we may not have a tester to check whether the cable is working properly or not. In this article, we will discuss some tips on how to test an RJ45 cable without a tester.
Method 1: Testing the cable using a laptop or PC
This is a simple method that involves connecting the RJ45 cable to your laptop or PC.
Step 1: Connect one end of the RJ45 cable to the network port on your laptop or PC.
Step 2: Connect the other end of the RJ45 cable to the network port on the other device.
Step 3: Open the control panel on your laptop or PC, click “Network and Sharing Center,” and check if the network connection is active.
If the network connection is active, it means the cable is functioning correctly. However, if the network connection is not active or showing limited connectivity, the cable may not be functioning correctly.
Method 2: Testing the cable using a multimeter
This is a more advanced method that requires the use of a multimeter.
Step 1: Set the multimeter to continuity test mode.
Step 2: Attach the red lead of the multimeter to one end of the RJ45 cable.
Step 3: Attach the black lead of the multimeter to the opposite end of the RJ45 cable.
Step 4: Test each pin on the RJ45 cable with the multimeter one by one. If there is continuity, the multimeter will beep, indicating that the pin is in good condition. If there is no continuity, the multimeter will not beep, indicating that the pin is not in good condition.
This process should be repeated for each pin on the RJ45 cable. If there is no continuity on some pins, it means that the cable is defective, and it needs to be replaced.
Method 3: Testing the cable using a cable scanner or toner
A cable scanner or toner is an advanced tool that helps locate and verify the cable's continuity. It sends a signal through the cable, which can be detected by the receiver.
Step 1: Attach the transmitter to one end of the RJ45 cable.
Step 2: Attach the receiver to the other end of the RJ45 cable.
Step 3: Scan the cable using the scanner/toner. If the receiver detects the signal, it means the cable is in good condition. If there is no detection, the cable may be defective.
Conclusion
In conclusion, we have discussed three different methods that can be used to test RJ45 cables without a tester. These methods include using a laptop or PC, using a multimeter, and using a cable scanner/toner. No matter which method you choose, it is essential to ensure the cable is functioning correctly before you start using it. Testing the cable before use can save you a lot of time and effort in the long run, and ensure that your network connection is stable and reliable.
