INSTRUMENTATION
▼ GENERAL CHARACTERISTICS
The LAN Cable Tester – continuity check – is a handy, low cost device for checking the conditions and operation of networks. With
its attractive design, it is equipped with a handy case to protect both the main and the remote units. It is specifically designed for
fast testing of mapping, polarisation, and continuity of pairs as well as data cable screening (as per EIA/TIA 568A&B).
It is equipped with RJ45 inputs on both the main and remote units, for connecting the section of circuit being tested. It is powered
with a normal 9 V battery. The LAN Cable Tester runs an automatic scan of any kind of cable equipped with RJ45 or RJ12 or RJ11
connectors. Furthermore, the remote terminal (separate from the central unit) makes it easy to test a channel which has already
been installed: a considerable advantage for maintenance technicians.
THE TESTER DETECTS THE FOLLOWING FAULTS:
• Open circuit • Crossed pairs
• Short circuit • Divided pairs, for cable runs from 0.5 to 200 metres
• Swapped wires of a given pair • Open cable screen
• PAIRS LED (GREEN) Indicates LAN cable twisted pairs. Pairs 1/2, 3/6, 4/5, 7/8 are all processed during the test.
• SCREEN LED (GREEN) Turns on when the screen of a cable is connected. Turns off when the cable is either not screened
or the screen is open.
• FAULT LED (RED) Indicates a fault on the pair of the LAN cable being tested.
The following four faults are highlighted on the front of the tester:
SHORT CIRCUIT : One of the wires of the pair is shorted somewhere along the length of the cable or at the connector.
SWAPPED: The two wires of a twisted pair have been swapped (e.g. 1-2 and 2-1)
CROSSED: Two complete pairs have been swapped (e.g. pair 1/2 run to 4/5 and 4/5 to 1/2)
DIVIDED PAIRS: Wires belonging to two different pairs have been used to make a connection.
This fault means that the connection is not between pairs and the advantages of twisted connections
are thereby lost.
• BATTERY LOW LED (RED) Turns on when the 9V battery charge is low.
• TEST BUTTON Press the button to test the LAN cable.
A RED LED indicates the type of fault detected on the pair being tested. If one of the GREEN LED’s does not light up (it is skipped
over during the test) this means that the pair in question has an OPEN wire. For a pair to pass the test, ALL GREEN LED’s must light
up, and NO RED LED may light up.
TESTING AND IDENTIFYING THE FAULT
Automatic quick test function – Press the test button for a moment to run an automatic test cycle. The result is displayed perma-
nently. The result can be one of the following:
a) ALL GREEN LEDS ON, NO RED LEDS ON: the cable is OK
b) ONE GREEN LED OFF: One wire of the pair is OPEN
c) ONE GREEN LED OFF and ONE RED LED ON: The pair associated to the green led (off) has a fault and the red led indicates
the type of fault
IMPORTANT - Do not connect the tester of the terminal while any end of the cable is still connected to any other device. This pre-
vents damage to the equipment or tester itself.
