How to Use a DataShark RJ45 Network Tester Kit

Computer networks are made up of physical cables that interconnect the various nodes and computer systems in the network, enabling the devices to communicate with one another. Paladin Tools manufactures the DataShark line of network tools, specifically the RJ-45 tester kit, to diagnose and test these vast computer networks to resolve any physical connectivity issues that may arise.

Network cables can become crimped or broken, resulting in downed communication.

Step

Plug the terminator into one end of the patch cable, or into the wall-jack end of the cable run you want to test.

Step

Plug the hand-held unit into the other end of the cable, or into the patch panel in the wiring closet, if you are testing a cable run.

Step

Turn the device on. The circle of lights on the front represent the four pairs of wire that makes up the network cable; each light should blink in sequence. When one of the LEDs lights up, that means the wire it is testing is properly wired and intact. If there are missing lights, you have a bad cable or run on the indicated wire.

Step

Re-crimp or terminate the cable if it is bad, and retest to see if that fixed the problem. If not, you may need to re-run the cable or throw it away.
