The 235 network cable tester is an easy and effective cable tester which can test all the wiring faults of 10Base2 (Coax), 10BaseTx, 100Base Tx, RJ45, 356A, TIA-568A, TIA-568B and Token Ring cables. It can identify not only the wiring faults, such as open pairs, shorted pairs, reversed pairs, crossed pairs and split pairs, but can also identify up to 4 different cables at one end. A large flashing LED displays the fault code, and the 4 pairs individual LEDs tells you which pairs are tested. The remote identifiers are provided to make a remote test. Just push the "TEST" switch. It will automatically run all tests within a few seconds and show you what faults are present. It is simple and easy to use.
