INTRODUCTION The 4 in 1 cable tester tests 4 common LAN and computer cables. It tests installed cables or patch cords with RJ-45, RJ-11, USB, and BNC connectors. It is intended to test cables with straight through connections not cables with reversed or transposed connections like some LAN crossover cables or reverse wired telephone cables.

such as rain snow, fog, or locations with steam, explosive gases or dusts. 11. Do not use tester in condensing atmospheres. That is, do not use tester in conditions where ambient temperature and humidity could cause condensation of water inside of the tester. 12.
(high voltage power lines, televisions, computer monitors, etc.). The tester may display readings that are in error. 21. Avoid usage near strong RF fields (radio or television transmitters, walkie talkie, cellular phones etc.).The tester may display reading that is in error. 22.
SPECIFICATIONS 1. Cables Tested: UTP and STP LAN cables Terminated in RJ-45 male connectors. (EIA/ TIA 568)RJ-11 cables with male connectors, 2 to 6 connectors installed. USB cables with Type A flat plug on one end and type B square Plug on other end.
OPERATION 1. General Information: The 4 in 1 Cable Tester performs its tests when the single button on its front panel is pressed and released.6 Status LEDs indicate the condition of the cable being tested, as well as informing the user that Power is turned on, and that the battery is good (or bad).8 additional connection LEDs light to indicate that specific wires in a cable...

are not installed in a wall or ceiling. Since both ends are accessible, one end can be plugged into the 4 in 1 Main unit, and one end into the Remote unit. It is not necessary to remove the Remote unit from its docked position on the Main unit.

6.2 Low Battery LED: The power LED should slimming. If it does, replace the battery. 6.3 No connection LED/Single Beep If the Remote is not connected to the main unit with a cable, or the cable has no intake conductors, the No Connection LED with light and the Beeper will sound once.

RJ-11 cables may have 2 connections, 4 connections, or as many as 6 connections. For 2 connection cables, LED 3 and 4 must light .For 4 connection cables, LED 2,3,4, and 5 must light. For6 connection cables, LED 1, 2,3,4,5, and 6 must light.
connections but do not indicate the location of the cross. RJ-11 cables used for telephone connections are often crossed. Even new cables are often crossed. This seldom affects the performance of standard analog telephone lines (POTS). Digital telephone lines and old touch-tone phones may be polarity sensitive, so a crossed cable may prevent then from working properly.

or flexing of the cable close to connector body. While the 4 in _ can identify a bad cable, it cannot determine if the wire or the connectors are at fault. The user must examine the different parts of the cable to determine the cause of failure and take the appropriate steps to correct the problem.

mail through the wire, or a crushed or pinched wire) if the 4 in 1 indicates a short. A visual examination of the RJ connectors may reveal the fault---but keep in mind that what-ever the cause of a connector problem (i.e. mis-wiring improper stripping of the wire, bad crimp, etc.) The only solution is to replace the connector.

purposely mis-wring, with their Receive and Transmit wires cross over. The 4 in 1 will test this as a bad cable, but it may work just fine as Crossover cable. 6.2 The 4 in 1 says my cable is good, but it does not work on my LAN: Many cable testers like the 4 in 1 only perform continuity style tests (open, short,...

Notes: Cross talk increases with the length of the cable. A LAN system will tolerate a certain amount of cross talk. A short cable (10ft or less) that is improperly) paired may work just fine. However, longer cables paired in exactly the same way, may not work.
