Description Of Errors Of Split Pairs; Test With More Remote Units - HT QUICKLAN6050N User Manual

5.2.2. Description of errors of split pairs

Inside the network cables, the eight conductors are twisted two by two, thus forming four
pairs: 1-2, 3-6, 4-5, 7-8 and this guarantees the performance declared by the
manufacturer. The error condition SPLIT PAIRS is given by the exchange of two
conductors belonging to different pairs, found in both positions of the cable to be tested
(see Fig. 8). Correspondence pin to pin is maintained, but the cables of the two pairs are
physically crossed. The two pairs thus crossed influence each other, thus making data
exchange at high frequency/speed difficult, if not impossible.

5.2.3. Test with more remote units

The instrument allows carrying out mapping tests also on multiple cables by using other
optional remote units and is capable of recognizing up to 4 remote units.
1. Switch on the instrument by pressing the key.
2. Select the category (CAT5, CAT6) of the cables to be tested (see § 5.1.3).
3. Select the type (UTP, STP) of the cables with RJ45 connector to be tested (see §
5.1.3).
4. Connect the end of one of the cables to be tested (e.g.: #3) to the instrument
connector RJ45 and to the corresponding remote unit (e.g.: #3) using the patch cables
as shown in Fig. 9.

5. Press the SET/UNIT key to select the current remote unit (e.g.: #3)
6. Press the TEST/
7. Disconnect the instrument, connect it to another cable and repeat the operations
starting from point 5.
