The TCT-355 Cable Tester is a convenient instrument for testing different shielded/unshielded wiring schemed communication cable with RJ-11 and RJ-45 connectors and coax cable. This tester can be used for testing cables before and/or after they are installed. Testing status is indicated by multiple LEDs. Soft vinyl case provides storage for the tester, remote and terminator. CATEGORY OF CABLE • Shielded/unshielded communication cable with RJ-11 and RJ-45 connectors. • Ethernet 10 Base-T, Token Ring, EIA/TIA-568A/B, AT&T 258A, and USOC. • 50 or 75Ω coaxial cable with BNC connectors. • 50 or 75Ω coaxial cable with F connectors. Must use BNC to F adapters (not supplied) Maximum testing length for all cable types is 1,000 feet MULTIPLE FUNCTIONS • Testing cables before or after their installation. • Mapping Function (to test individual wire pairs or coaxial cables). • Cable identification (straight or cross-pinning). • Pair identification (straight or cross-pinning). • Open/short wiring test. • Shield opens • Automatic two speeds OPERATION INSTRUCTIONS Warning: 1. Caution: Do not connect the cable tester to live circuits as it may be damaged by over voltage. 2. Turn on the TCT-355. If the power light ( O ) does not light, please replace the 9V battery with a new one. 3. When testing communication cable with RJ11 connectors, use only the RJ11 jacks on the tester and remote. How to Use the TCT-355: 1. Turn on the power switch, the power light will flash (“S” for low speed test). 2. To test communication cable, connect an end of the cable to the tester and the other end of the cable to the remote. 3. The LED’s will light in sequence 1 - G on the tester. Check that the correct corresponding LED lights on the remote unit per your wiring configuration. A short is indicated by no LED’s lighting on the remote. An open wire/shield by no LED’s lighting on the tester and remote. 4. To test a coaxial cable, connect one end of the coaxial cable to the connector on the tester and connect a terminator to the other end. If the cable is good, the TCT-355 indicator light “B” will be lit green and the terminator LED will be lit. If the light does not turn on, the cable has an open connection or short.
