The test tool is designed around a "Test as You Go" philosophy. This reduces the time necessary to install and service LAN cables by allowing ONE PERSON to detect most cable failures from only one end of the cable. The test tool tests for incorrect pairing (split pairs), miswires, shorted and open wires on all twisted pair cables, as well as shorts on coaxial cables. The test tool comes with the following: 1 620 Softcase 1 RJ45-RJ45 Straight-Through Patch Cable (EIA/TIA 4 Pair Cat5) 1 RJ45-RJ45 Female Coupler 1 User Manual 1 Cable Identifier #1 1 Quick Reference Card 1 Warranty Registration Card Caution To reduce wear on the test tool connector, leave the patch cable connected to the test tool and use the patch cable to connect to the cable under test.

Selecting a Cable Type Characteristics for a variety of LAN cables are designed into the test too and can be accessed through SETUP. See Table 3. 6 CableMeter Preparing the Test Tool for Use Note Cables not wired according to the predefined cable list cause the test tool to detect failures. However, the test tool will determine the cable's length and display the actual cable wiring with the wire map function. It may be possible to use the test function by making an adapter that causes the cable to appear to be properly wired to the test tool. To set up the test tool for the desired cable, perform the following: 5. 6. Press C or Duntil the desired category is displayed, then press E. Press C or D until the desired wire size is displayed. Note You can check the cable selection at any time other than during the setup mode by pressing the E key. The cable characteristics are now defined by the factory settings for the cable selected. However, cables coming from different batches or manufacturers can have characteristic variances of up to 20 %, causing deviations in length measurements. To obtain more accurate measurements, calibrate the test tool to the specific cable under test. Note The number of steps necessary to select a cable definition will depend on the type of cable selected. 1. 2. 3. 4. Turn the test tool on by selecting TEST, LENGTH, or WIRE MAP. Press A. Press C or D until the desired cable type is displayed, then press E. Press Cor D until the desired wiring standard is displayed, then press E. Calibrating the Test Tool to the Cable When calibrating the test tool to a specific cable, the cable should be at least 100 feet (30 m) long and of the same type and category as the cable under test. Calibrating with cables longer than 100 feet (30 m) will improve length measurement accuracy. During the calibration process, if the cable is found to be defective or if the cable is less than 50 feet (15 m), "BAD CABLE" is displayed and the calibration process is terminated. 7 620 Users Manual Caution For proper calibration, connect the cable under test directly to the test tool, not through a patch cable. Caution To ensure accurate measurements, make sure conductive objects, including fingers, do not come in contact with any of the connectors while the test tool is measuring the cable under test. To calibrate the test tool to the currently selected cable, perform the following: 1. Connect a good cable of known length, 100 feet (30 m) or longer, to the appropriate test tool conenctor and turn the rotary switch to TEST, LENGTH, or WIRE MAP. 3. abm04f.eps Note When you select a cable type for which the test tool has already been calibration, "CAL" will appear in the second line of the display. To erase this calibration and use the factory settings, remove all cables from the test tool, press D D until "YES" is displayed, and press E. Press C D until YES is displayed, and then press E. The test tool takes a few measurements on the attached cable and displays the measured length. Note If you have just completed the cable selection process, the test tool should already be i the calibration setup selection. 2. Press A and then E until the following display appears. abm05f.eps 8 CableMeter Making Tests and Measurements 4. Press C D until the known cable length is displayed, and then press E. These cable parameters are stored and will remain in memory even if the test tool is turned off. All future measurements for this cable type are compared to these new parameters until another cable is selected or another calibration is performed. Table 4. Active Pin Connections DB-9 Line Name Data Connector Color Red Green Black Orange 8-Pin RJ45 1 6 5 9 RX+ RXTXTX+ 4 5 3 6 Making Tests and Measurements The test tool displays test results in relation to individual pin numbers. For example, in the LENGTH mode, the following display indicates the twisted pari connected to pins 1 and 2 is 301 feet long whilc the pair connected to pins 3 and 6 is 300 feet long. Note When you test STP cables, the IBM Data Connector in the STP Adapter Kit or AMP part number 555414-2 must be used with the Cable ID Unit. abm06f.eps Testing Cables The TEST function teststhe attached cable and indicates PASS or FAIL based on hte cable's compliance with the parameters stored in the test tool for the selected cable. The tests that are performed (Table 5) depend on whether or not a Cable ID unit is connected to the far end of the cable. When you are testing STP cabling, the pin number displayed always corresponds to the pins at the STP (DB9) connector. Table 4 shows the connections for the active pins. 9 620 Users Manual Table 5.

"CAL" appears in the second line of the display if a cable calibration has been performed The test tool may not sense the Cable ID Unit under some open and short conditions. The test tool will alternately display a ? and a number when the Cable ID is detected but its number can not be dertmined with certainty. 10 CableMeter Making Tests and Measurements When testing coaxial cables with a termination, the test tool displays the totatl resistance of the termination and cable wires. abm09f.eps Coaxial cables must be unterminated for the test tool to display the cable's length. An open in a coaxial cable looks just like an unterminated cable. A length measurement that is less than the known cable length would indicate a possible open in the cable. The test tool sounds three short tones and displays FAIL if a failure is detected. Additional information about the failure is printed on the second line of the display and if the ] symbol is displayed, additional information can be viewed with the D C keys. Note The failure messages refer to individual wires rather than pairs of wires. Failure messages for the TEST mode are described in Tables 6 and 7. 11 620 Users Manual Table 6. Test Failures (without Cable ID Unit) Failure Short* (UTP/FTP/STP) abm10f.eps Display Description Displays shorted wires and the most likely distance to the short.

Pair Length Indicates that the length of the pairs within a cable are abnormally different. Use LENGTH to check pair lengths. A portion of the cable assembly has split pairs or a poor quality cable such as telephone wire was used instead of LAN type cabling which may cause excessive crosstalk. Detects anomalies that do not fit a specific category or failure.** Split Pair Fault *Flashes the number of the wires incorrectly connected. **These non-specific faults are as follows: · A cable with a resistive path between the wires. Displays measured resistance. · Shield connected with UTP cable selected. · UTP cable connected with STP or COAX selected. 14 CableMeter Making Tests and Measurements Measuring Cable Length The test tool measures the length of both twisted-pair and coaxial cables. If the test tool is not calibrated to the cable under test, then factory default characteristics are sued to compute hte length. If a more accurate length measurement is desired, refer to "Calibrating the Test Tool to the Cable". Before a length measurement is made, the test tool performs diagnostic tests to prevent any cable failures from corrupting the length measurement. All failures are described in the "Testing Cables". To measure the length of a cable, do the following: 1. 2. 3. Connect the cable under test to the appropriate connector on the test tool. Turn the rotary switch to LENGTH. This step can be omitted if you know the cable selection is correct for the cable under test. Press E to check the cable selection. The test tool displays the cable selection for a few seconds and then starts the test. "CAL" appears in the second line of the display if a cable calibration has been performed for the selected cable type. If the test tool is not set up for the cable under test, refere to "Preparing the Test Tool for Use" to select a new cable setting. Note When the display flashes 999' (350 m) during a length measurement, the length of the cable exceeds the tst tool's range of measurement. The information that is displayed depends on the type of cable selected. For twisted pair cables, each pair has its corresponding length measurement. A 5 percent difference in length between pairs is not uncommon. For EIA/TIA 4PR cable with no failures, the display shows the following: abm21f.eps abm22f.eps 15 620 Users Manual Length of a coaxial cable terminated in a resistance cannot be determined by the test tool. Only the total resistance of the wire and termination is displayed. An unterminated coaxial cable 445 feet long will display the following: of the display if a cable calibration has been performed for the selected cable type. If the test tool is not set up for the cable under test, refere to "Preparing the Test Tool for Use" to select a new cable setting. Note If you select the COAX wire type while in the WIRE MAP mode, the test tool will perform the LENGTH function on the cable. Assuming the cable attached to the test tool is a EIA/TIA 4 pair cable with no failures, the following display indicates a good cable: abm23f.eps Checking the Wire Map Using the test tool's Wire Map function and a Cable ID Unit, you can determine the wiring of both the near and far end of the cable. To test the Wire Map, perform the following: 1. 2. 3. Connect the cable under test to the appropriate connector on the test tool. Turn the rotary switch to WIRE MAP. This step can be omitted if you know the cable selection is correct for the cable under test. Press E to check the cable selection. The test tool displays the cable selection for a few seconds and then starts the test. "CAL" appears in the second line Near End Far End abm24f.eps The top line always displays the near end of the cable; the second line always displays the far end. When the test tool detects a Cable ID Unit but cannot determine the ID number, #? Is displayed for the ID number. The test tool will alternately display a ? and a 16 CableMeter Checking the Wire Map numbe when the Cable ID is detected but the Cable ID number cannot be detemined with certainty. Without a Cable ID Unit connected to the far end of the cable, the test tool displays "--" for the ID number. The following display indicates the near end wiring of a cable without a Cable ID Unit connected. Pins connected to wires comprising twisted pairs are grouped together in the display. abm25f.eps The IBM data connector contains self-shorting connections between pins 5 and 6 (TX- and RX-) and 1 and 9 )RX+ and TX+) on the STP connector. Since this is a normal connection for the IBM data connector, the tst tool does not display a failure. In the wire map function, the presence of these shorts are displayed as shown below: abm26f.eps 17 620 Users Manual Table 8.
