Cable Tester ST-248 for UTP/STP - RJ45 networks

Tester for coaxial cables or network cables ending with RJ-45 connectors. You can use it to find whether the cable is damaged, has short-circuited wires, or determine whether it's a patch or cross type. It can be used to test free cables using just the tester, or fixed cables using the tester and a special terminator that simply connects to the other end of the cable.
