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. SAFETY RULES& WARNINGS 1. 2. 3. Read all instruction in this manual before using this tester.
. Follow the recommendations of any Trade Organizations or Regulatory Agencies whose scope encompasses the use of this tester failure to do so may result in damage to the tester or injury to the user. 5. Do not open this tester for maintenance without first disconnecting it from all external circuitry. Failure to observe this precaution may result in damage to the tester or injury to the user. 6.

That is, do not use tester in conditions where ambient temperature and humidity could cause condensation of water inside of the tester. Do not use this tester if it is wet, either from exposure to the weather, or after cleaning the case of the tester.
(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. Remove the battery when the tester may be left unused for longer than month. Chemical leakage from the battery could damage the tester. PRODUCT FEATURES 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

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 connected. Note: Only one cable can be tested at a time. i.e. A BNC cable and an RJ-45 cable cannot be tested simultaneously. 2.
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. 4. Testing Installed cables: To test cables installed in ceilings or walls, or in applications that prevent the ends from being in the same location, the Remote can be detached from 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. 6.4 Connected LED/lo-Hi Beep /Numbered LEDs If the Connected LED lights and the Beeper emit a Lo-Hi beep, examine the numbered LEDs (i.e. LEDs numbered to 8 and the S LED).
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. The numbered LEDs DO NOT indicate that a GOOD connection exists, only that a connection exists. If the Short or Cross LEDs are lit, there is a fault in the cable. 6.
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. CABLE REPAIR 1.
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. 3. Which end is bad? The 4 in 1 like many cable testers, cannot fine the location of the fault, or even determine which end or connector is bad. It simply knows that a fault exists.
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. Consequently, it is not necessary for the user to know the exact cause of the problem, simply to make sure that he installs the new connector correctly! 6.
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, crossed, etc). Ethernet LAN cables are constructed in a special way. The 8 wires inside are grouped into 4 pairs of 2 way. The 8 wires inside are grouped into 4 pairs of 2 wires each.
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. This explains why an installer can make short jumper cables that work (although they are improperly paired), but when he installs RJ-45’s in exactly the same way on a longer cable, the cable does not work. 6.
machine may not answering machine may not answer when the line rings. MAINTENANCE Your 4 in 1 cable tester is a precision test instrument and, when used as described in this manual, should not require maintenance .there are no internal adjustments. Calibration is not required. To clean the outside of the tester, use a cloth dampened with a mild detergent solution. Do not use any abrasive cleansers or chemical solvents that may damage the case of the tester.
